Immunefi

The main bug bounty platform for crypto, DeFi and smart contracts, with very large payouts.

Immunefi hosts bounties for blockchain protocols, where critical findings can pay out six or seven figures. Programs spell out in scope assets, severity tiers and payout caps, and many publish past disclosures. Payouts usually require identity verification (KYC). Expect to need Solidity and DeFi knowledge.
