PROFILE

Madhur Shrimal

Worked on Layr-Labs repositories, delivering five features and a key bug fix over three months with a focus on backend and blockchain development using Go and Solidity. Enhanced eigenda’s security by replacing private-key-derived salts with cryptographically secure random values, reducing exposure risk in registration flows. Developed slashing functionality and unified BLS signer abstractions in eigensdk-go, introducing API key authentication and improving contract interaction reliability. Upgraded dependencies and implemented gRPC-based access controls for remote signers. Addressed documentation gaps in eigenda-proxy by correcting CLI flag usage, ensuring accurate JSON output and smoother onboarding. Emphasized maintainability, cryptographic hygiene, and secure system integration throughout.

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).
