2.6 Precautions for MainNet
Critical Precautions for Mainnet Smart Contract Deployment: Involving Real Money
Deploying smart contracts on the mainnet, where real money and assets are at stake, demands heightened vigilance and adherence to stringent precautions. Failing to exercise due care could lead to financial losses or security breaches. Hence, it is of paramount importance to prioritize the following measures:
Thorough Testing on TestNet: Leave no stone unturned in conducting rigorous testing on the testnet environment to identify and rectify potential flaws, ensuring a robust and secure contract.
Code Review and Audits: Engage in meticulous code review and, if possible, enlist the services of third-party security audits to fortify the contract against vulnerabilities and risks.
Gas Optimization: Optimize contract code to minimize gas usage, reducing deployment costs and ensuring economic viability.
Backward Compatibility: Safeguard existing systems by ensuring the contract's backward compatibility, ensuring seamless interactions with previous versions.
Verify Contracts: Verify the contract code post-deployment on the blockchain explorer to maintain transparency and verify its integrity.
Test with Small Funds: Prioritize initial testing with small amounts of currency or tokens, guaranteeing flawless functionality before involving larger sums.
Emergency Stop Mechanism: Embed an emergency stop mechanism, enabling the prompt suspension of contract operations if necessary.
Community and Peer Review: Seek insights from the blockchain community and peers to benefit from diverse perspectives and meticulous scrutiny.
Security Best Practices: Adhere unwaveringly to security best practices, leaving no room for lapses in secure coding and mitigating potential risks.
Avoid Hardcoded Values: Eliminate hardcoded values to steer clear of security vulnerabilities and potential breaches.
Secure Key Management: Implement foolproof key management practices, ensuring robust protection of private keys and sensitive account data.
Monitor Contract Activity: Closely monitor contract activity and transactional flow to swiftly identify any anomalous behavior or suspicious activities.
