Madhur Shrimal contributed to Layr-Labs’ eigenda and eigensdk-go repositories by building security-focused backend features and improving developer experience. He replaced private-key-based salt generation with cryptographically secure random salts, reducing exposure risk in registration flows. Madhur also introduced a unified BLS signer abstraction, enabling flexible signing and API key authentication for remote signers, which improved both security and maintainability. His work involved Go, Solidity, and gRPC, with careful attention to code abstraction and dependency management. Additionally, he addressed documentation issues in eigenda-proxy, updating CLI guidance to ensure reliable JSON output, which streamlined onboarding and reduced support overhead for downstream users.
February 2025 — Focused on improving documentation for the eigenda-proxy CLI to ensure reliable JSON output and downstream data processing. Delivered a critical README fix that updates the CLI flag usage to --json, preventing broken examples and reducing onboarding friction. No new features delivered this month; major bug fix centered on documentation and CLI guidance.

January 2025 performance summary: Focused on strengthening security, inter-contract correctness, and signing reliability across Layr-Labs repos (eigensdk-go and eigenda). Delivered slashing functionality with contract binding updates and a robust BLS signing abstraction, plus API key authentication for Cerberus signing. Upgraded dependencies to remote signers and introduced API key-based access controls, enabling scalable, secure signing workflows and improved governance of contract interactions. These efforts reduce risk, improve maintainability, and accelerate future feature delivery.

December 2024 monthly summary for Layr-Labs/eigenda: Delivered a key security hardening feature by replacing private-key based salt generation with cryptographically secure random salts for churner client and operator registration. This change mitigates private-key exposure in salt calculation and strengthens cryptographic hygiene across critical registration flows. Implemented via a targeted code change in the eigenda repo (commit 2d7a94e992161c115cbf4e4711fec416e83cf25d).
