To ensure the reliability of your smart contract when deploying it on mainnets, it is important to extensively test it on both local and public testnets. Here are some steps you can take to do so:
• Create a comprehensive test suite using tools like Forge or Hardhat to thoroughly test each function of your smart contract. This will help you identify and fix any bugs before deployment.
• Deploy your smart contract on a testnet and offer bug bounties to encourage other developers to audit it, test it, and submit solutions for any bugs they find.
• Invite a diverse group of people to test your smart contract, including other developers, investors, and potential users of the application that will utilize the smart contract.
• When ready for the mainnet, consider a beta deployment in which certain functions are only available for a trial period. After this period, you can use the upgradeability feature to replace it with a fully tested and finalized version (example code in the image below).
