1. Developed a robust Solidity NFT Freeze Contract on Ethereum blockchain, integrating secure ownership transfer and OpenZeppelin's Transparent Proxy pattern for upgradeability, achieving enhanced traceability and transparency through event emission.2. Developed a vesting contract on the Sui blockchain in Move language to enable GTH-to-Hydro token migration. Implemented flexible vesting mechanisms with secure ownership management to ensure a smooth transition.3. Designed TypeScript-based testing scripts for Sui's programmable transaction blocks, enabling the validation of staking contract functionalities like stake, un-stake, and reward. This approach reduced overall testing time by 60% and improved test coverage, ensuring comprehensive user acceptance validation.
