Everything You Need to Know About the Smart Contract Auditing Process

As the blockchain ecosystem grows, smart contracts have become the backbone of decentralized applications (dApps), DeFi protocols, NFTs, and more. However, with the rise in adoption comes a surge in exploits, hacks, and vulnerabilities. From the infamous DAO hack to more recent flash loan attacks, one common theme runs through them all — insufficient smart contract security.

That’s where smart contract auditing comes in. In this guide, we’ll walk you through a detailed, step-by-step look at the smart contract auditing process — what it involves, who performs it, and why it’s crucial for any serious blockchain project.

What is Smart Contract Auditing?

Smart contract auditing is the process of reviewing the code of a smart contract to identify vulnerabilities, bugs, inefficiencies, or any deviation from expected functionality. It aims to ensure that the code is secure, reliable, and functions exactly as intended.

Smart contract audits are typically conducted before the contract is deployed to the blockchain, although post-deployment audits can still be beneficial.

Why is Smart Contract Auditing Important?

Smart contracts are immutable once deployed — meaning bugs or vulnerabilities cannot be fixed without deploying a new version. A single overlooked flaw can lead to millions of dollars in losses. Auditing is critical for:

Security: Preventing exploits such as reentrancy attacks, overflows, and logic errors.

Reliability: Ensuring the contract performs consistently under all conditions.

Compliance: Aligning with industry standards and regulatory requirements.

Investor Confidence: Providing assurance to users, investors, and partners.

Step-by-Step Smart Contract Auditing Process

Step 1: Collecting Project Information

Before diving into the code, auditors gather as much context as possible about the project:

Architecture Documents: Diagrams and overviews of how contracts interact.

Whitepapers or Technical Papers: Explaining protocol logic, tokenomics, etc.

Business Logic: Understanding what the contract is supposed to do.

Dependencies: Identifying third-party libraries (e.g., OpenZeppelin, Chainlink).

A deep understanding of the contract's intended functionality helps auditors assess whether the implementation matches expectations.

Step 2: Setting Up the Development Environment

Auditors clone the repository and set up a local development environment. This usually includes:

Installing tools like Hardhat, Truffle, or Foundry

Running tests using Mocha, Chai, or similar testing frameworks

Analyzing the contract with Slither, MythX, or Oyente

Setting up the environment ensures smooth access to source code, build scripts, and deployment logic.

Step 3: Manual Code Review

This is the core of the audit process.

Key things auditors look for:

Logical Flaws: Does the logic align with the intended function?

Access Control Issues: Are functions properly restricted (e.g., onlyOwner)?

Arithmetic Errors: Are there overflows/underflows (especially without SafeMath)?

Reentrancy Vulnerabilities: Can functions be recursively called?

Unchecked External Calls: Are calls to external contracts validated?

Gas Optimization: Are there inefficiencies in gas usage?

Manual reviews require deep technical understanding and often uncover complex or subtle bugs that automated tools miss.

Step 4: Automated Analysis

While manual review is critical, automated tools help catch low-hanging fruit and known vulnerabilities.

Common tools include:

Slither: Static analysis tool for Solidity

MythX: Security analysis platform

Securify: Formal verification and analysis

Manticore: Symbolic execution engine

These tools detect:

Unused variables

Uninitialized storage

Integer overflows

Dangerous calls

Code duplications

Automated tools are fast and scalable but should supplement — not replace — manual reviews.

Step 5: Running and Reviewing Test Cases

Well-written smart contracts come with extensive unit and integration tests.

Auditors:

Review existing tests for coverage and completeness

Create new test cases for edge scenarios

Ensure fail-safes trigger under abnormal inputs

Check upgradeability (for proxy contracts)

A robust testing suite adds another layer of confidence to the audit findings.

Step 6: Simulating Attack Vectors

Auditors simulate real-world attack scenarios such as:

Reentrancy attacks (e.g., exploiting withdraw functions)

Flash loan exploits (e.g., manipulating token prices temporarily)

Front-running (exploiting mempool visibility)

Phishing via delegatecall or fallback functions

Economic vulnerabilities like sandwich attacks or oracle manipulation

Advanced auditors might even use tools like Echidna or Foundry’s fuzz testing to automate attack simulations with randomized inputs.

Step 7: Documenting Findings

Auditors compile a comprehensive report with:

Issue Severity Levels:

Critical: Can lead to loss of funds or full system compromise

High: Major impact but may require certain conditions

Medium: Non-catastrophic but exploitable

Low: Minor issues or edge case bugs

Informational: Style issues, unused variables, etc.

Details of Each Issue:

Description

Impact

Code reference (line numbers)

Reproduction steps (if applicable)

Suggested fix

Clear documentation ensures the development team can quickly understand and fix each vulnerability.

Step 8: Remediation and Re-Audit

After receiving the report, the development team works to resolve the issues. Once changes are made, a re-audit is performed to:

Verify all fixes were correctly implemented

Check for any new vulnerabilities introduced during fixes

Update the audit report to reflect remediated issues

A second audit (or “fix verification round”) ensures that the system is ready for deployment.

Step 9: Final Report and Public Disclosure

Once everything is verified, the final audit report is released. This might be:

Private: For internal review only

Public: Shared on GitHub or the project's website

Timestamped On-chain: Some teams publish audit reports directly to the blockchain for transparency

Public disclosure builds trust, especially if the project is launching a token sale or going live with user funds.

Best Practices for Smart Contract Auditing

To ensure a successful audit, here are some tips for developers:

Write Clean, Modular Code: Use clear naming, comments, and structure.

Use Battle-Tested Libraries: Rely on well-audited libraries like OpenZeppelin.

Document Thoroughly: Include README, design decisions, and architectural overviews.

Start Audits Early: Don’t wait until launch day — start audits as soon as the core contracts are stable.

Audit Frequently: Especially after major upgrades or integrations.

How Long Does a Smart Contract Audit Take?

The duration depends on several factors: Project SizeApproximate TimeSimple (1-2 contracts)3–5 daysMedium (3–6 contracts)1–2 weeksComplex (DeFi protocols, DAOs)3–6 weeks

Rushed audits are ineffective. A thorough, careful audit is always worth the time and cost.

Conclusion

Smart contract auditing is an indispensable process in blockchain development. From identifying vulnerabilities and logic flaws to simulating real-world attack scenarios, audits provide a vital layer of security and trust for decentralized applications.

If you’re building on the blockchain, don’t treat auditing as an afterthought. A comprehensive audit can save your project — and your users — from financial disaster.

The Future of Blockchain Hiring: What Makes a Great Solidity Developer?

As this technology gradually matures and permeates mainstream sectors like finance, healthcare, real estate, or even the gaming sector, the competition for highly skilled blockchain talent has surged to an unprecedented level. One prominent position that this hiring wave has thrust into the limelight is the Solidity developer-an expert in the smart contract language used to develop decentralized applications (dApps) on the Ethereum and EVM-compatible platforms. For any company aiming to stay ahead of others, Hiring Solidity Developers has turned out to be one of the strategic decisions that directly influence product security, scalability, and speed to market.

1. Mastery of Solidity and EVM Fundamentals

Such talent in Solidity is best described as an engineer with a skill set to develop basic smart contracts, but still possessing knowledge of, say, Solidity and its relationship with the EVM. They know well the compilation of contracts into byte code, optimization in terms of gas so as not to put undue costs on the user while maximizing efficiency, along with the storage and management in memory. They breathe in the concepts of the contract lifecycle, state mutability, gas consumption, and storage layout. Thus, harnessing this knowledge, they can produce highly optimized working contracts that meet real-world Blockchain constraints.

2. Security-First Mindset

Security is something optional for blockchain; it is everything. With one bug in the smart contract, millions of dollars could have been lost or forever locked. This is why the most elite Solidity developers will put security first right from day one. They are thoroughly aware of the common vulnerabilities such as reentrancy, access control issues, integer overflows/underflows, denial-of-service, and timestamp manipulation. Great developers write clean, modular, and testable code. After the coding phase, the code is usually audited manually and with all sorts of automated tools, such as Slither, MythX, and Hardhat. They also stay abreast of recent exploits in the space to ensure they don't repeat somebody else's past mistakes.

3. Experience with Smart Contract Frameworks

Writing code alone does not do the trick for building production-ready decentralized apps; one has to capitalize on the best tools available for facilitating streamlined development and firm deployment. The best Solidity developers are well-versed in Hardhat, Truffle, or Foundry frameworks to expedite testing, debugging, and deployment. Setting up a blockchain environment locally, writing both unit and integration tests, mocking contract behavior, and the ability to fork to test against live chain data are some of the skills they possess. These are some of the developers you want on your team in order to speed up and scale your investment into a stable development pipeline.

4. Understanding of DeFi and Blockchain Architecture

Many Solidity developers usually work on protocols that form the very core of the decentralized finance ecosystem. A great developer understands the architecture of DeFi primitives such as decentralized exchanges (DEXs), automated market makers (AMMs), lending/borrowing protocols, oracles, and stablecoins. Not only do they understand how to build out such systems, but also tokenomics design, gas optimization, and edge cases such as flash loans or severe market volatility. This contextual understanding aids them in choosing proper design decisions that result in a more solid and future-proof application.

5. Strong GitHub Portfolio and Community Involvement

In open source development, your code is your reputation. Some distinguished Solidity programmers usually maintain an active GitHub profile with smart contract projects, contributions to widely used protocols, or original tools/libraries. They do so to show the industry their chops, as well as their style of coding, documenting, and detailing the work. Many developers are active in hackathons, participate in DAOs, publish technical blogs, and respond on Ethereum StackExchange and Crypto Twitter. Their ability to be a lifelong learner, teach, and collaborate gives them so much more value for the long haul.

6. Collaborative and Agile Working Style

Despite the technical intricacies of blockchain, it is still very much a team discipline. The best Solidity developers know how to work in cross-functional teams, communicate succinctly, iterate fast, and feel comfortable with agile workflows. They collaborate with product managers, UI/UX designers, DevOps engineers, and fellow developers to materialize one shared vision. Whether it means showing up at daily stand-ups, preparing exhaustive documentation, or assessing pull requests, these developers allow themselves to be fairly active players who bear the wider success of the product and team on their shoulders.

Conclusion

The future of blockchain hiring will favor Solidity developers who are not just brilliant technically but similarly conscious of security, efficient, and team-oriented. As the industry grows toward maturity and with more institutional and enterprise use cases being integrated, the talent bar continues to rise higher. As an organization, you should join this trend by investing in a team recruitment strategy.

If you are building on Ethereum or EVM-compatible chains, there could not be a better time. Be deliberate and purposeful in your search. Look out for candidates with a perfect mix of technical depth and practical on-the-job experience, able to prove their worth in terms of code, communication skills, and community presence. Hire a Solidity developer with these capabilities means you aren't just hiring for a vacancy-anytime you hire such a developer, you lay down the foundation for creativity, security, and a winning future.

Whether you're new to blockchain or transitioning from Web2, avoiding common mistakes early can save you time, frustration, and even money. In this article, we’ll break down 9 common mistakes to avoid when learning Web3 development, along with practical advice to get ahead.

1. Skipping Blockchain Fundamentals

Many developers jump straight into coding smart contracts without truly understanding how blockchains work. A solid grasp of consensus mechanisms, transaction flow, gas fees, and blocks is essential.

If you don’t understand the system you’re building on, you’ll likely introduce security flaws or build inefficient applications.

2. Neglecting Smart Contract Security

One of the most critical areas in Web3 development services is smart contract security. Vulnerabilities like reentrancy attacks, integer overflows, or improper access control can cause major losses.

Before deploying anything live:

Study secure development practices

Use auditing tools like Slither or MythX

Learn from past exploit case studies

3. Focusing Only on Ethereum

Ethereum is popular, but it’s not the only chain. Developers should also explore other ecosystems like:

Polygon (Layer 2 scaling)

Solana (high throughput)

BNB Chain

Arbitrum and Optimism (Layer 2 rollups)

Modern Web3 development companies work across multiple chains to optimize performance, fees, and user experience.

4. Ignoring Web2 Skills

Many newcomers believe Web3 requires abandoning traditional web skills. In reality, you still need:

HTML/CSS

JavaScript frameworks like React or Next.js

API integration

A great dApp still needs a solid UI. Web3 solutions that ignore frontend development often end up with poor usability.

5. Not Testing Thoroughly

Failing to test smart contracts and dApps properly is a costly mistake. You should use testnets (like Sepolia, Mumbai, or Fuji) and automated testing tools to catch bugs early.

Use:

Hardhat

Foundry

Truffle

Ganache

Testing is standard practice for every successful Web3 development agency.

6. Underestimating Gas Fees

Gas fees on chains like Ethereum can fluctuate wildly. Writing inefficient code can lead to high execution costs for users.

Web 3.0 developers should optimize smart contracts and understand gas estimation to keep dApps affordable.

7. Not Understanding Token Standards

A good Web 3.0 development company should be familiar with:

ERC-20 (fungible tokens)

ERC-721 (NFTs)

ERC-1155 (multi-token standard)

Knowing when and how to use each standard is essential to creating interoperable Web3 platforms.

8. Skipping Documentation and Community Resources

The Web3 space evolves rapidly. Developers who don’t read documentation or participate in developer forums fall behind quickly.

Stay active on GitHub, Discord, and follow official docs for tools like Ethers.js, Web3.js, and The Graph.

9. Building Without Real-World Use Cases

Many developers jump into projects without solving real problems. Building “just another NFT site” with no unique value won’t succeed.

Study existing Web3 development services and identify how to innovate. Whether it’s finance, gaming, social media, or supply chains—every great project starts with a meaningful problem.

Smart Contract Development Tools and Frameworks How to Use Them?

smart contract development applications are presented as the disruptive tool that could redefine transactions and contractual agreements.

Choose your language

Use an IDE

Test your code

Deploy your contract

Update your contract

Learn from others

1.Choose your language

Before extending smart contracts, selecting a programming language that can meet your requirements is the first thing that you need to do. The reason behind this is that different blockchains support varying languages; thus, you should think about how each option compares in terms of compatibility, functionality and safety. For instance, Ethereum supports Solidity which is an advanced level language meant solely for smart contracts while there is also Vyper that is much easier and more secure. On the other hand, Cardano, Polkadot as well as Tezos embrace languages that are either based on or compatible with Haskell, Rust and OCaml respectively. When selecting any of these languages, you should take into account the availability of documentation as well as tutorials and other community resources.

2. Use an IDE

An incorporated development environment (IDE) is a software tool that offers a handy and person-pleasant interface for writing, checking out, and debugging code. Using an IDE assists you to save time and avoid mistakes while growing Smart contracts. There are many IDEs available for smart settlement improvement, along with Remix, Truffle, Hardhat, and Visual Studio Code. Each IDE has its own functions, advantages, and disadvantages, so you should examine them and choose the one that fits your workflow and goals. For instance, Remix is a web-based IDE that lets you put in writing, assemble, and set up Smart contracts directly for your browser, whilst Truffle is a framework that offers a collection of gear for trying out, deploying, and coping with Smart contracts on diverse networks.

3. Test your code

Verifying your programming is essential for ensuring that your smart contracts are high quality and safe. This is because smart contracts cannot be modified or undone; therefore, any faults or weaknesses could have grave repercussions. As such, you must test your code extensively prior to deploying it on the mainnet.

There are several tools and frameworks that can be used for testing your code such as

Ganache,

Mocha,

Waffle and

MythX.

The implications of these tools and frameworks is that one can create a simulated or private blockchain environment, run unit tests, code analysis and detect potential issues. In addition, it is essential to research smart contract development best practices and standards such as using the latest compiler version, avoiding complex logic and observing coding conventions.

4. Deploy your contract

Once you have examined your code and tested its functionality and protection, you could install your smart contract on the mainnet. To try this, you need to have a pocket that can engage with the blockchain Development network, inclusive of

Metamask,

Geth, or

Parity.

You also need to have a few cryptocurrency to pay for the gasoline expenses, which are the expenses of executing transactions at the community. Depending on the network congestion and the complexity of your settlement, the fuel charges can range significantly. You can use tools which include Gas Station Network or Gas Now to estimate and optimize the fuel charges. You have to additionally screen the fame and overall performance of your settlement after deployment, the usage of equipment inclusive of Etherscan, Tenderly, or Blockscout.

5. Update your contract

Although Smart contracts are immutable through layout, there can be situations where you need to replace or adjust your settlement. For instance, you may want to restore a worm, upload a characteristic, or exchange a parameter. To try this, you want to apply a clever agreement upgradeability pattern, that is a way that permits you to alternate the logic or state of your agreement without affecting its deal with or facts. There are one-of-a-kind kinds of upgradeability patterns, inclusive of proxy, delegatecall, and diamond. After reviewing every example, it can be concluded that they all have some good and bad things, thus one is obliged to deeply think about this trade-off when choosing among them in regards to: flexibility vs. security vs. simplicity. Moreover, you should also adhere to guidelines and best practices which promote smart contract upgradability like OpenZeppelin Contracts or Upgrades Plugins.

6. Learn from others

Essential Skills to Look for When Hiring Solidity Developers

The demand for skilled Solidity developers is growing as blockchain technology continues to evolve. Whether you're building decentralized applications (dApps) or launching a new smart contract-based project, finding the right talent is crucial. Hiring Solidity developers for scalable blockchain solutions ensures that your project remains secure, efficient, and future-proof. However, hiring the right developer is not just about knowing Solidity—it requires a deep understanding of blockchain security, Ethereum architecture, and best development practices. A well-rounded Solidity developer can help you navigate the complexities of blockchain development while ensuring smart contracts are optimized and secure. But what specific skills should you prioritize when evaluating candidates? Let’s explore the essential technical and soft skills to look for in a Solidity developer.

1. Proficiency in Solidity and Smart Contract Development

A strong Solidity developer possesses deep knowledge of the Solidity programming language, including its syntax, data types, functions, and control structures. They can write secure, gas-efficient,and well-optimized smart contracts that fit and work seamlessly on the Ethereum blockchain. Knowledge of the variations and updates of Solidity is also important since upgrades normally introduce improvements that are critical for security and optimal functionality. Furthermore, a competent developer goes beyond basic Solidity coding to include an understanding of best practices such as modular contract design, efficient storage management, and code reuse with an eye toward maintainability. Knowledge of mastery in contract inheritance, event-driven programming, and function visibility modifiers is a prerequisite for building robust smart contracts that integrate smoothly within a decentralized ecosystem.

2. Understanding of Ethereum and EVM

Since Solidity is primarily used for Ethereum-based applications, a solid grasp of the Ethereum Virtual Machine (EVM) is essential. A developer should understand how EVM executes smart contracts, manages storage, and processes transactions efficiently. They should also be knowledgeable about gas optimization techniques, as excessive gas consumption can make transactions expensive and inefficient. Familiarity with Ethereum’s architecture, consensus mechanisms, and scalability solutions like Layer 2 technologies (Optimistic Rollups, zk-Rollups) is a plus, as these solutions help reduce network congestion and transaction fees. Additionally, understanding Ethereum’s account structure, nonce management, and cryptographic functions like Keccak-256 hashing is crucial for implementing secure blockchain applications. Developers with hands-on experience in deploying contracts on testnets such as Goerli, Sepolia, or Polygon Mumbai will be better equipped to handle real-world development scenarios.

3. Knowledge of Security Best Practices

Security remains one of the most important concerns for the blockchain development community, since vulnerabilities in smart contracts can lead to huge monetary losses. A Solidity developer should have a good understanding of how to recognize and prevent common attack vectors such as reentrancy attacks, integer overflow/underflow, front running, and gas limit problems. A Solidity developer should know how to apply security best practices in Solidity, such as the checks-effects-interactions pattern, secure generation of random numbers (Chainlink VRF), and implementing access control mechanisms to limit unauthorized interactions with the contract. Working knowledge with security tools such as Slither, MythX, and OpenZeppelin's security libraries constitutes an asset, as they help in automating the detection of vulnerabilities. Further, an understanding of formal verification and fuzz testing might ensure that smart contracts behave as expected under all conditions. The good-working developer should follow secure development practices as pictured, such as integrating multisig wallets and time-locking critical functions to prevent unauthorized access to essential contract operations.

4. Experience with Smart Contract Testing and Auditing

Testing is a significant part of blockchain development, given that once smart contracts are deployed, they are immutable. A seasoned Solidity developer must be proficient enough in testing frameworks such as Hardhat, Truffle, or Foundry to write automated tests for smart contracts well before their actual deployment. Testing the contracts on both unit and integration testing, and assuring contract stability through a forked network simulation, would be expected of these developers. Familiarity with gas profiling tools and gas coverage reports could help identify contract functions that are inefficient before actual deployment. They must also be aware of auditing best practices and security review methodologies by companies such as CertiK, OpenZeppelin, and Trail of Bits, which can help find vulnerabilities before they become actual issues. Developers that are actively participating in bug bounties and security research display their devotion to advancing the security of blockchain applications.

5. Familiarity with DeFi and NFT Protocols

A Solidity developer working on a DeFi or NFT-related project must be well-versed in common blockchain standards such as ERC-20, ERC-721, and ERC-1155, which lay down the method of operation of tokens on Ethereum. The developer should know how tokenomics, staking mechanisms, liquidity pools, and decentralized exchanges (DEXs) seamlessly integrate with DeFi protocols. Knowledge of lending platforms, yield farming strategies, and governance mechanisms like DAOs (Decentralized Autonomous Organizations) may also be crucial to DeFi projects. For the NFT side of things, familiarity with royalty mechanics, metadata storage (IPFS, Arweave), and on-chain/off-chain rendering techniques is required. All these developers that have experience in deploying and interacting with Uniswap, Aave, Compound, or OpenSea smart contracts will be better suited to build scalable and interoperable blockchain solutions.

6. Backend and Frontend Development Knowledge

Smart contracts are programmed in Solidity; however, in addition to Solidity, blockchain applications need front- and back-end development for a smooth customer interface. A full-fledged Solidity developer must also learn the usage of web3.js, ethers.js, and React or Next.js frameworks for integrating smart contracts with frontend developments. Backend knowledge is also beneficial for performing off-chain computations, indexing blockchain data, and setting up API gateways in Node.js, Python, or Rust. Also, knowledge of GraphQL (The Graph), IPFS for decentralized storage, and Chainlink as your oracle solution can significantly increase your dApp's capabilities. A Solidity developer with much knowledge about frontend and backend interactions, including API security and serverless architecture, will pitch in with the idea of full-stack blockchain development.

7. Problem-Solving and Debugging Skills

Smart contract development is an encompassing zone requiring intense problem-solving. Solidity developers must be well versed with debugging tools like Remix IDE, Hardhat console, and Tenderly, which help identify issues during development. They should be able to analyze failed transactions, optimize gas fees efficiently, and troubleshoot contract execution errors. Critical thinking and attention to detail are vital in troubleshooting unexpected behaviors of blockchain applications. Low-level Solidity debugging, such as opcodes and call traces, is valuable in addressing very intricate contract problems. Developers who regularly engage in discussions on blockchain communities and forums, such as Ethereum Stack Exchange or Solidity GitHub conversations, can stay well-informed regarding the new debugging processes or industry vanguard.

Conclusion

Hiring the right Solidity developer is crucial for the success of your blockchain project. From smart contract development to security, testing, and DeFi integration, a skilled Solidity developer should possess a wide range of expertise. Evaluating candidates based on their proficiency in Solidity, Ethereum architecture, security best practices, and full-stack blockchain development will ensure that your project is built on a strong foundation. Additionally, an ideal developer should demonstrate continuous learning, adaptability, and a proactive approach to solving blockchain-related challenges. If you're looking to Hire Solidity developer for blockchain projects, make sure they have the technical and problem-solving skills to build secure, scalable, and efficient smart contracts that drive long-term success.

What is a smart contract security audit, and what are the best practices for cryptocurrencies?

As the mainstay of decentralisation in the majority of blockchain applications, the term "smart contract" is often used in the cryptocurrency industry.

In case you're wondering, smart contracts are digital contracts that self-execute and have a preset agreement between all parties (e.g., buyer and seller). When all parties have fully complied with or completed their respective sides of the contract, these specified terms and conditions, which are written into lines of code and saved on the blockchain, are automatically carried out.

Having defined what smart contracts are, it is now obvious that they are essential to both blockchain technology and decentralised applications (dApps). Furthermore, a potential security vulnerability or discovered error in the self-executing digital contract can be extremely dangerous and must be prevented at all costs, resulting in the need for a smart contract security audit. Smart contracts are crucial to the overall success of blockchain transactions, so any flaw or discovered error must be prevented at all costs. So what does a security audit of a smart contract actually mean?

Benefits and Best Practices of Smart Contract Security Audit for Crypto Projects

Beginning with token contracts/crowdsales, dApps, DeFi projects, NFT markets, and any other blockchain project that uses smart contracts, smart contract auditing is necessary for a number of activities.

Any project may gain from smart contract audits in a variety of ways, including the detection and prevention of significant systemic faults, building confidence with investors and end users, risk assessment and mitigation, and the construction of hack-proof walls around a project, among others.

Even if there are several advantages, it is crucial for projects to follow industry best practises for creating smart contracts, which include but are not limited to the following:

1. Conduct regular audits and pentests: Even when a system seems to be faultless, it is crucial to routinely carry out audits and penetration tests. This is because security holes and vulnerabilities may always be exploited by hackers, even when they don't seem to exist. However, it is far simpler to identify possible security flaws in your system and to give yourself enough time to repair them before an attacker targets your platform by executing a routine security audit.

2. Adhere to the blockchain security checklist: Following thoroughly investigated and practically carried out checklists is always a good idea for the security of your blockchain-based applications. Sticking to multifactor authentication, enforcing IAM control, utilising SIEM, and other important items are on some well-known checklists.

3. Run automatic security scans: This can help you find code issues that could result in security vulnerabilities and stop various kinds of assaults.

4. Use only trusted blockchain tools: ConsenSys, SWC-registry, Awesome Buggy ERC20 Tokens, MythX, Octopus, Echidna, SmartCheck, Manticore, Ouente, and other reliable blockchain tools are among them.

Why You Should Care

Security audits of smart contracts are now considered best practise for cryptocurrency projects. Investors and end users rely on smart contract security audits to assess how trustworthy the project they are investing in or using is, much too how people care about what Trustpilot has to say about a website.

In Cyphershield.tech we also have BSC smart contract audit. By certifying your upcoming project on the Binance Smart Chain, you have the opportunity to lock in millions of dollars' worth of value. Your smart contract is analyzed by our BSC smart contract audit professionals using a combination of automatic and manual audit techniques.

¿Cómo empezar a programar en Solidity?

omo ya hemos mencionado, Solidity es el nombre de un lenguaje de programación de alto nivel, muy parecido al conocido JavaScript, usado para la programación Web. Este lenguaje es usado para programar smart contracts o contratos inteligentes para la blockchain de Ethereum, los cuales serán ejecutados por la EVM. Más específicamente, Solidity es un lenguaje de alto nivel que nos permite programar de forma sencilla para EVM y que luego puede ser compilado bytecode para que finalmente se ejecuten en la Máquina Virtual Ethereum. Al ser un lenguaje de alto nivel, significa que los desarrolladores cuentan con una herramienta sencilla para programar. Evitando así la dificultad de programar usando OP_CODES o códigos de operación, o bytecode de forma directa, algo que sí ocurre en Bitcoin. Como resultado, la creación de aplicaciones descentralizadas (DApps) resulta una tarea mucho más sencilla de realizar, revisar y testear, quedando al alcance de cualquier persona con conocimientos básicos de programación.

Herramientas para comenzar a programar en Solidity

Documentación y Libros sobre Solidity Si tienes experiencia en programación, seguramente sabrás la importancia de contar con una buena documentación oficial sobre las posibilidades del lenguaje de programación que estás usando. Pues bien, esta premisa se cumple a conciencia con Solidity. En primer lugar, la documentación oficial de Solidity es excelente. En suweb oficial puedes encontrar toda la información técnica que necesitas sobre las potencialidades y mejoras que presenta este lenguaje con cada nueva versión. Además, el desarrollo y mejora al lenguaje es constante demostrando que la comunidad busca mejorar e implementar nuevas funciones para hacer más sencillo y seguro la programación de DApps. Si lo que deseas es programar en Solidity y ya tienes conocimientos previos de programación y desarrollo en otros lenguajes, este es el primer lugar al que debes ir. Si por el contrario, no tienes conocimientos en programación y desarrollo, primero deberás conocer las formas y operaciones básicas de los lenguajes de programación para entonces iniciar tu proceso de aprendizaje sobre Solidity. Por otro lado, dos de los libros más importantes dedicados al desarrollo en Solidity son Solidity Programming Essentials de Ritesh Modi y Ethereum Smart Contract Development de Mayukh Mukhopadhyay. Ambos libros han sido editados por Packt y están pensados para que interesados en el mundo de programación de Solidity pasen de ser principiantes a avanzados programadores en este lenguaje. Si quieres conocer aún más sobre Ethereum entonces puedes complementar tu lectura con Mastering Ethereum escrito por Andreas Antonopoulos y Gavin Wood. Si unes todos estos elementos de lectura entonces comenzarás a comprender muy bien qué es Ethereum y cómo puedes usar Solidity de forma efectiva para programar tu primera DApp y tal vez, con suerte, cambiar el mundo a mejor. Herramientas para programación y depuración Ahora bien, conocer la parte teórica es solo un primer paso para comenzar tu camino a programar en Solidity. Pero es un paso sin valor si no eres capaz de llevar ese conocimiento teórico a lo práctico. Para hacer posible esto deberás contar con herramientas para programar y depurar lo que escribas en este lenguaje. En ese caso, los IDE o Entorno Integrado de Desarrollo (Integrated Development Environment, en inglés), serán tu herramienta para lograr esto. Un IDE es un programa que cuenta de forma integrada con una serie de herramientas que harán más sencilla tu labor de programar en un determinado lenguaje. Generalmente estos IDE contienen correctores de sintaxis, integración con librerías, localizadores de errores y modos que te permiten probar tu aplicación antes de desplegarla de forma pública. En el caso de Ethereum, existen dos grandes IDE soportados oficialmente por la comunidad. El primero de ellos es Remix. Remix es un IDE web que podemos usar desde nuestro navegador y con el cual podremos programar y probar nuestras aplicaciones escritas en Solidity sin necesidad de instalar nada. Otra herramienta muy usada en el mundo del desarrollo sobre Ethereum y Solidity es Truffle. De hecho, Truffle es por lejos la herramienta mejor integrada del mundo Ethereum para la programación en Solidity. Pero por otro lado, la cantidad de opciones de Truffle lo hace una herramienta compleja de usar, en especial, si estás comenzando a aprender, por lo que solo es recomendable para personas con conocimientos más avanzados. Del lado contrario está ETHFiddle, una sencilla web que te permite ejecutar código escrito en Solidity y aprender a programar de la forma menos compleja posible. Sin embargo, si lo que deseas es crear tu propio ambiente de programación usando alguna otra herramienta, también puedes hacerlo. Existen otros IDE y plugins que te permiten hacer esto. Por ejemplo, IntelliJ IDEA es un IDE para múltiples lenguajes de programación, pensado especialmente para programar en Java, pero que también puede ser usado para programar usando Solidity. Otras herramientas de desarrollo como Atom o Visual Studio Codetambién te permiten instalar plugins que habilitan la programación usando Solidity. En cualquiera de estos casos, contarás con todo lo necesario para poder armar tu código Solidity. Herramientas de simulación Otra herramienta vital para la programación es contar con acceso a la testnet de Ethereum. Esto es necesario ya que deberás poder probar tu aplicación en un entorno muy similar al real, pero donde no te cueste dinero ninguna prueba o error. Para ello puedes instalar un nodo de Ethereum y seguir los pasos de configuración para trabajar sobre alguna de las testnet de Ethereum, o bien acceder a las redes testnet usando un deployer (desplegador) con dicha capacidad para el IDE que estés usando. El uso de una red testnet te permitirá poner tu DApp en un ambiente muy parecido al que podrías encontrar en la red principal de Ethereum, y constatar así que la misma funciona de forma correcta en todo momento. Sin embargo, una forma más sencilla de lograr esto es Ganache. Ganache es una herramienta que te permite simular un nodo completo de Ethereum sin los costos asociados de tener un nodo que mantiene todo una blockchain en tu computador. Gracias a esto, Ganache es una herramienta mucho más sencilla, rápida de usar y que obtiene los mismos resultados. Además, cuenta con una amplia integración con Truffle y es fácilmente integrable con otros IDE. Herramientas de análisis de seguridad y monitoreo Si bien la tecnología blockchain es muy segura, la seguridad es algo que requiere proactividad en todo momento. Por esa razón, la comunidad detrás de Ethereum y Solidity ha creado una serie de herramientas de análisis que ayudan a mejorar enormemente la seguridad del código escrito para nuestros smart contracts evitando con ello que los bugs se nos escapen y terminen ocasionando pérdidas a nuestros usuarios. Herramientas como MythX, Mythril o Alethio son algunas de las opciones más potentes en este sentido, permitiéndote potentes análisis de seguridad (para los casos de MythX y Mythril) y para la monitorización de tus smart contracts (en el caso de Alethio). Otros recursos de aprendizaje Por supuesto, esto es solo una pequeña parte del universo de opciones que existen en la comunidad de Ethereum. En dicho caso, una de las recopilaciones más completas de herramientas y recursos de aprendizaje para Ethereum y Solidity la puedes encontrar en este repositorio de ConsenSys. Acá podrás acceder a distintos recursos de gran relevancia en la comunidad para aprender al máximo como programar en Solidity y sacarle el mayor provecho a tus conocimientos en este lenguaje. Pero ¿Qué tal si en lugar de solo nombrar herramientas te mostramos el potencial de Solidity en un sencillo ejemplo? Pues bien, si te gusta la idea solo debes continuar leyendo.

Nuestra primera experiencia con Solidity

Para nuestra primera de programación en Solidity usaremos Remix. Nuestra elección de esta herramienta responde a que permite probar de forma muy sencilla el código que escribimos, así como nos brinda salidas de depuración sencilla y la facilidad de usar distintas versiones de Solidity. En ese caso, lo primero que deberás hacer es ir a esta web y seleccionar el plugin “Solidity” con el fin de tener todas las opciones de programación y depuración para este lenguaje. Es cierto que la mejor forma de aprender algo es haciéndolo. Y es importante que programes, pero intenta ponerle sentido a lo que haces. Así que busca hacerlo con una idea de proyecto en mente, con ello te encontrarás ante situaciones reales que solventar. Para encontrar buenas ideas es importante empaparte de la cultura que rodea toda la tecnología blockchain. Una tecnología que ha sido creada para descentralizar todo lo descentralizable. Seguro que, a poco que pienses, encontrarás situaciones donde unos pocos monopolizan el poder, toman decisiones de forma unilateral y todo ello sin transparencia. Recuerda que la tecnología blockchain se ha creado para hacer un planeta más justo, democrático y transparente. Todo ello sin importar que caiga quien tenga que caer por medio: gobiernos, reyes, religiones, corporaciones,… No tengas miedo a plantar cara a lo que sea que consideres injusto.
