During October 2025, Ming Zhuang developed core cross-chain signing features for the phantom/wallet-sdk repository, focusing on Ethereum and Solana integration. He implemented Ethereum EIP-712 typed data signing and Solana transaction signing within the embedded provider, using TypeScript and JavaScript to ensure standards compliance and robust parsing of raw signed outputs. This work enabled dApps to sign typed data per Ethereum specifications and handle single or multiple Solana transactions, improving compatibility and reducing integration friction for multi-chain wallets. By addressing a bug in HL withdrawals, Ming enhanced signing flow reliability, supporting faster onboarding and a better developer experience for wallet integration.
