During December 2025, Tom Levine developed a flexible EIP-712 signing feature for the Hyperliquid SDK in the LayerZero-Labs/devtools repository. He integrated Fordefi and Fireblocks APIs to enable secure signing of Hypercore EIP-712 messages, addressing enterprise requirements for robust transaction workflows. Working primarily in TypeScript, Tom focused on API-first design and security-conscious development, ensuring compatibility with industry standards and reducing friction in signing processes. His work laid the foundation for broader ecosystem integration by documenting the approach and supporting future signing flows. The project demonstrated depth in blockchain development, smart contract integration, and cross-team technical collaboration.
