At Tesuji Inc., I focused on enhancing the functionality of the gaming ecosystem by enabling seamless NFT management for users. I implemented web3modal to allow users to connect to their legacy wallets, enabling them to unstake their NFTs and transfer them to a new Particle MPC wallet associated with their account. This integration facilitated a smooth transition, allowing users to stake and unstake their NFTs with ease.Additionally, I updated the code to incorporate Particle Network authentication, ensuring safe and secure user login, registration, and user information updates. This enhancement provided a robust security layer for user accounts and streamlined the authentication process.I also refactored the existing codebase, replacing outdated and unsupported dependencies with Particle wallet and web3.js. This overhaul ensured the staking and unstaking processes were fully operational and secure, significantly improving the overall user experience and system stability.
