Immunefi Guide for Bug Bounty Hunters

Immunefi hosts many of the largest smart-contract and Web3 bug bounty programs. High maximum rewards attract strong competition, so speed and focus become critical advantages.

Key Characteristics

• Heavy focus on blockchain, DeFi, bridges and infrastructure
• Often multi-million dollar reward pools
• Detailed severity definitions and impact-based payouts
• Public GitHub repositories for most in-scope contracts

Effective Approach

• Read the full policy – out-of-scope assets and known issues are common
• Monitor the linked repositories for new commits and upgrades
• Prioritise changes that alter critical paths (auth, funds movement, governance)
• Write reports that clearly demonstrate impact and economic risk

Why Live Monitoring Helps

When a protocol deploys a new contract or upgrades an existing one, the fresh code is the highest-value surface. Researchers who receive the commit alert first can analyse the diff before the rest of the community notices.
