PROFILE
Alex Graham
Alex Graham developed core wallet infrastructure for the hyperledger-labs/splice-wallet-kernel repository, focusing on secure key management and robust transaction signing. Over three months, Alex introduced a modular keystore system with a public API, enabling reliable key management and internal signing workflows using TypeScript and Node.js. He integrated Fireblocks signing, supporting both single and multi-user flows, and optimized transaction lookups with pagination and direct endpoint access. Alex improved system performance by reducing unnecessary API calls and enhanced traceability with smarter key caching and transaction identifiers. His work included comprehensive documentation and type clarifications, resulting in a maintainable, secure backend foundation.
