Clients featured in the bounties
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. When in doubt, send an email to firstname.lastname@example.org and ask us.
The Ethereum Specifications detail the design rationale for the Execution Layer and Consensus Layer.
It might be helpful to check out the following annotations:
Clients run the Ethereum Network, and they need to follow the logic set out in the specification and be secure against potential attacks. The bugs we want to find are related to the implementation of the protocol.
Currently execution layer clients (Besu, Erigon, Geth and Nethermind) and consensus layer clients (Lighthouse, Lodestar, Nimbus, Teku and Prysm) are included in the Bug Bounty Program. More clients may be added as they complete audits and become production ready.
See the Solidity SECURITY.MD for more details about what is included in this scope.
Solidity does not hold security guarantees regarding compilation of untrusted input – and we do not issue rewards for crashes of the solc compiler on maliciously generated data.
Only the targets listed under in-scope are part of the Bug Bounty Program. This means that for example our infrastructure; such as webpages, dns, email etc, are not part of the bounty-scope. ERC20 contract bugs are typically not included in the bounty scope. However, we can help reach out to affected parties, such as authors or exchanges in such cases. ENS is maintained by the ENS foundation, and is not part of the bounty scope.
For each valid bug you find you’ll earn rewards. The quantity of rewards awarded will vary depending on Severity. The severity is calculated according to the OWASP risk rating model based on Impact on the Ethereum Network and Likelihood. View OWASP method
The EF will also provide rewards based on:
Quality of description: Higher rewards are paid for clear, well-written submissions.
Quality of reproducibility: A Proof of Concept (POC) must be included to be eligible for rewards. Please include test code, scripts and detailed instructions. The easier it is for us to reproduce and verify the vulnerability, the higher the reward.
Quality of fix, if included: Higher rewards are paid for submissions with clear description of how to fix the issue.

The bug bounty program is an experimental and discretionary rewards program for our active Ethereum community to encourage and reward those who are helping to improve the platform. It is not a competition. You should know that we can cancel the program at any time, and awards are at the sole discretion of Ethereum Foundation bug bounty panel. In addition, we are not able to issue awards to individuals who are on sanctions lists or who are in countries on sanctions lists (e.g. North Korea, Iran, etc). Local laws require us to ask for proof of your identity. You are responsible for all taxes. All awards are subject to applicable law. Finally, your testing must not violate any law or compromise any data that is not yours and must take place on local running testnets.
