Research Project: RWA Claim Protocal: Asynchronous Settlement & Liquidity Protocol Developed an asynchronous settlement and liquidity infrastructure for tokenized Real-World Assets (RWAs) bridging multi-day banking delays (T+1 to T+3) via an ERC-7540 asynchronous vault, a real-world state attestation middleware, and a peer-to-peer secondary claim marketplace using Solidity, TypeScript, Node.js, Express, EIP-712, and React. Skills/Keywords: Solidity · ERC-7540 · ERC-4626 · EIP-712 · Smart Contracts · OpenZeppelin · TypeScript · Node.js · Express · React · Vite · Hardhat · Foundry · Web3 · Ethers.js · Cryptographic Attestation · Fail-Closed Architecture Result: Architected a fail-closed protocol achieving a 99/100 certification, verified T+0 liquidity, zero premature minting across 135+ tests, and 481,690 lifecycle gas (~38% lower than ERC-721 wrappers).
