Diamond-Hand.Me
During the NFT and crypto bull market, and even right now in the bear market, many traders have a lot of regrets... Some sold their Bored Ape Yacht Club NFTs at 1ETH, which later reached 120 ETH. Others sold Azukis at 2 ETH (me included), which later reached 30 ETHAfter many such painful experiences, I started to look for tools that could help me get rid of my emotions and prevent myself from panic-selling. I couldn't find any trustworthy tools. However, I know that smart contracts are the perfect vehicle to create such tools as they can allow users to directly interact with programs without having to trust a central/third party with their assets.So I created my own tool – Diamond-Hand.Me a platform designed to help traders take control of their emotions and stick to their trading strategies. The core feature of the platform is a time-lock mechanism, which allows users to set a future date before which they cannot withdraw their assets. For added flexibility, I included an emergency unlock option, where users can withdraw their funds prematurely by paying a penalty fee that they set themselves. This ensures that traders have the tools they need to stay disciplined while still having a safety net in case of emergencies.Leveraging the power of smart contracts, Diamond-Hand.Me operates as a fully decentralized platform, providing a trustless and transparent system. Unlike traditional platforms where users must rely on a central authority to secure their assets, all the functionality of Diamond-Hand.Me is encoded directly into the immutable smart contract. This means the rules of the platform cannot be altered or manipulated, and users can interact with the platform knowing their assets are protected by the plain, verifiable logic of the code. Trust is built not on promises, but on the reliability and security of the program.Coding this smart contract took a lot of time. Not only was this my first large smart contract undertaking, it was also very important for the code to be reliable and immune to malicious attacks. I wrote unit tests spanning over 4,000 LOC, and worked with Certik to further conduct a security audit to ensure this platform could be trusted.Here is the smart contract code if you'd like to take a look!
