Bug Bounty Program
Earn up to 1,000,000 USD and a place on the leaderboard by finding protocol, client and language compiler bugs affecting the Ethereum network.
Clients featured in the bounties











In Scope
Our bug bounty program spans end-to-end: from soundness of protocols (such as the blockchain consensus model, the wire and p2p protocols, proof of stake, etc.) and protocol/implementation compliance to network security and consensus integrity. Classical client security as well as security of cryptographic primitives are also part of the program. All bug disclosures and vulnerability submissions must be made through our bug submission form (opens in a new tab).
Vulnerability severity qualifications
Severity is assessed based on a each discovered vulnerability's unique ability to do the following:
- Slash >0.01% of validators
- Trivially cause network splits affecting >0.01% of the network
- Be able to bring down >0.01% of the network by sending a single network packet or an onchain transaction
- Slash >1% of validators
- Trivially cause network splits affecting >5% of the network
- Be able to bring down >5% of the network by sending a single network packet or an onchain transaction
- Slash >33% of validators
- Trivially cause network splits affecting >33% of the network
- Be able to bring down >33% of the network by sending a single onchain transaction
- Slash >50% of validators
- Exploit an EIP/specification or client bug to easily create an infinite amount of ETH which is finalized by the network
- Steal ETH from all EOAs
- Burn ETH from all EOAs
- Take down the entire network by sending a single malicious onchain transaction that ends up crashing all clients

Rewards are paid out in ETH or DAI after the submission has been validated, usually a few days later. Local laws require us to ask for proof of your identity. In addition, we will need your ETH address.
We can donate your reward to an established charitable organization of your choice.
We aim to respond to submissions as fast as possible. Due to the increase in AI submissions, please allow up to a week for us to respond to your submission.
Submitting anonymously or with a pseudonym is OK, but will make you ineligible for ETH/DAI rewards. To be eligible for ETH/DAI rewards, we require your real name and a proof of your identity to be sent, encrypted using PGP on our secure drop website, to our legal team at the Ethereum Foundation who are the sole reviewers of the documentation. Donating your bounty to a charity doesn’t require your identity.
Please let us know if you do not want your name/nick displayed on the leader board.
Every found vulnerability / issue is assigned a score. Bounty hunters are ranked on our leaderboard by total points.
