Best Practices and Pitfalls in Smart-contracts Development

A computer program called “smart contract” is made to automatically carry out the terms and conditions of a contract. Because it is based on blockchain technology, the contract can be executed securely and decentralized. Moreover, Smart contract uses the blockchain to verify and record every transaction, it is extremely safe and impervious to tampering. A smart contract guarantees that all parties to the agreement are bound by its terms because once created, it cannot be changed or removed. The process of Smart Contract Development is complex and revolutionary for Web3 apps. A careful consideration of best practices and potential pitfalls is discussed in this blog.

Best Practices for Smart Contract Development

Understanding of best practices and potential pitfalls is important when it comes to develop a smart contract. For businesses to get successful Smart Contract, these best practices can be time-saving, if followed;

Prioritize Security with Community Engagement:

Establish a robust security framework by actively involving the community through bug bounty programs, encouraging ethical hackers to identify and report vulnerabilities.

Safeguard Against Vulnerabilities with Design Patterns:

Integrate proven design patterns like check effects interaction, ensuring the intended impact of operations; secure transfer ability to protect assets during transfers; emergency stops for immediate intervention, and access restrictions for controlled contract interactions.

Maintain Comprehensive Documentation:

Develop and uphold detailed documentation outlining proof-of-work processes and procedures, ensuring a clear and comprehensive resource for developers, auditors, and stakeholders to reference.

Enhance User Experience through Clear Instructions:

Provide users with explicit instructions on contract usage, potential interactions, and troubleshooting procedures. Include real-time performance metrics to offer transparency and foster user trust. Additionally, share contact information for relevant authorities to address any concerns promptly.

Utilize Static Analysis Tools:

Employ advanced static analysis tools to delve into the codebase, identifying and rectifying style inconsistencies and potential code errors. This proactive approach aids in maintaining code quality and adherence to best practices.

Conduct QA Cycles and Security Audits:

Implement thorough Quality Assurance (QA) cycles that encompass functional and security testing. Conduct regular security audits to ensure the robustness of the development process and achieve high test coverage, minimizing the probability of overlooked vulnerabilities.

Optimize Smart Contract Code for Web3 Efficiency:

Enhance the efficiency of Smart Contract code in the Web3 context by optimizing it for cost efficiency. This involves streamlining operations to reduce computational expenses associated with blockchain transactions.

Understanding Gas as a Computational Unit:

Develop a deep understanding of Gas as the unit measuring computational effort in blockchain operations. This knowledge is crucial for optimizing Smart Contract execution, as it directly influences transaction costs and processing speed.

Overcoming Immutability Challenges:

Address the inherent challenges of Smart Contract immutability by exploring third-party solutions that facilitate updates and modifications. This includes strategies for transitioning states and migrating users seamlessly during contract upgrades.

Streamline Manual Transitions and User Migration:

Simplify the process of manual transitions during Smart Contract upgrades. Prioritize a seamless user migration experience by minimizing disruptions and providing clear communication on the transition process.

Pitfalls to Avoid When Developing Smart Contracts

  1. Firstly, mitigate vulnerabilities like integer arithmetic errors, reentrancy attacks, and front-running attacks and avoid pitfalls like default visibility and proper handling of ERC-20 tokens.
  1. Secondly, take mitigation steps like conducting audits thoroughly. Moreso, locate and remove weaknesses through comprehensive audits.
  1. Thirdly, document every identified smart contract issue to prevent unforeseen risks. And, regularly check the source code for potential bugs with an internal security team. It is essential to enhance security through bug bounty programs, allowing participants to earn rewards for identifying vulnerabilities.
  1. Fourthly, Protect against unauthorized attempts by deploying alert services or monitoring tools. Companies should maintain continuous monitoring as a proactive measure against potential threats.
  1. The early stages of blockchain technology underscore the significance of rigorous testing and auditing. Developers must grasp blockchain features and limitations for effective architecture design. Lastly, maintain transparency and open communication with stakeholders throughout the development process.

Significance of Smart Contract Development For Traditional Industries:

1. Finance and Banking

  • Smart Loan Contracts: Automating lending and borrowing processes ensures efficiency and transparency.

2. Real Estate

  • Tokenized Property: Real estate tokenization broadens access, allowing fractional ownership and facilitating automated transactions.
  • Smart Tenancy Contracts: Automation in tenancy agreements streamlines property management.

3. Supply Chain

  • End-to-End Visibility: Smart Contracts provide end-to-end visibility in the supply chain, reducing information gaps and delays.
  • Automated Compliance: Ensures efficient compliance with industry regulations at every stage.
  • Smart Legal Contracts: Automation of legal processes, including contract execution and enforcement, reduces the need for intermediaries.
  • Immutable Record-Keeping: Smart Contracts offer immutable and transparent records, enhancing trust in legal transactions.

5. Healthcare

  • Patient Data Security: Smart Contracts enhance the security of patient data through decentralized and encrypted systems.
  • Automated Healthcare Processes: Streamlining processes like insurance claims and billing improves efficiency.

6. Cross-Border Payments:

  • Efficient Remittances: Blockchain and Smart Contracts enable fast, low-cost, and secure cross-border payments.
  • Financial Inclusion: Facilitates financial inclusion by connecting individuals and institutions worldwide.


In conclusion, the potential of Smart Contract creation in Web3 is vast but requires a great attention to detail. Many of the industry leaders have developed smart contracts and many new businesses are looking to advance their paper contact system to digital contracts. Before getting it developed, one should consider knowing the pitfalls of the development of smart contratcs as well as what best practices. BloxBytes is a blockchain and web3 development company that specializes in assisting clients for choosing the cost effective smart contract development solution to thrive across industries. 

Consider looking for a partner who advocate for the prioritization of security, staying abreast of industry advancements, and learning from past experiences for robust and secure development of smart contract.
