PROFILE

Madhur Shrimal

Madhur Shrimal contributed to Layr-Labs’ eigenda and eigensdk-go repositories by building security-focused backend features and improving cryptographic workflows. He replaced private-key-based salt generation with cryptographically secure random salts, reducing exposure risk in registration flows. Madhur developed a unified BLS signer abstraction, standardizing signing mechanisms and introducing API key authentication for remote signers using Go and gRPC. He also delivered slashing functionality and contract binding updates to strengthen inter-contract correctness. Additionally, he improved documentation for the eigenda-proxy CLI, ensuring reliable JSON output for downstream processing. His work demonstrated depth in backend development, cryptography, and smart contract integration using Go and Solidity.

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).
