PROFILE
Zhongxi Shen
Worked on BitGoJS, focusing on backend development and cryptographic security for Ethereum transaction workflows. Delivered a feature enhancing ECDSA multi-party signing by introducing a round-domain separator for additional data, which improved integrity and reduced cross-round leakage risk. Addressed a critical bug by enforcing hex-prefix signatures in the Abstract Ethereum module, ensuring data integrity and compatibility with Ethereum tooling. Improved test reliability by adjusting ECDSA TSS test timeouts and documenting the rationale, reducing flaky failures in continuous integration. Utilized TypeScript and cryptography expertise, maintained clear commit traceability, and prioritized code hygiene while delivering targeted security and reliability improvements to the codebase.

Apr 1, 2026In April 2026, delivered a security-focused enhancement to ECDSA multi-party signing in BitGoJS. Introduced a round-domain separator for the additional data (adata), ensuring adata is uniquely tied to each signing round, thereby improving integrity and reducing cross-round leakage risk. This work aligns with HSM-1513 and strengthens the cryptographic guarantees of the signing flow. No major bugs fixed this month; maintenance focused on delivering a high-value security feature and preparing for follow-on hardening and audits. By delivering this feature in BitGoJS, we improved the trust margin for customers relying on MPC signing.
