Bug Bounty Program

Consensys bug bounty program

At Consensys, we take cybersecurity seriously and value the contributions of the security and DeFi community. As the leading blockchain company, our bug bounty program (also known as vulnerability disclosure program), is the right place for skilled security researchers and bug bounty hunters to be recognized and rewarded for reporting vulnerabilities or weaknesses in our technology,  keeping our DeFi community safe.

If you believe you’ve identified a potential security vulnerability in our products or services, please report it to us using one of the following options disclosed in this Program.

Your participation in this Bug bounty program is voluntary and subject to the terms and conditions set forth here.  By reporting a vulnerability to ConsenSys, you acknowledge that you have read and agreed to fully comply with the rules disclosed in this program.

Reporting a vulnerability

Bugs and vulnerabilities can be reported using these options:

Disclosure Policy

  • Please do not disclose your findings outside this program until we have had the opportunity to review and address them with you.

  • Follow HackerOne’s disclosure guidelines.

Program Rules

  • Please provide detailed reports with reproducible steps. If the report is not detailed enough to reproduce the issue, the issue will not be eligible for a reward.

  • Submit one vulnerability per report, unless you need to chain vulnerabilities to provide impact.

  • When duplicates occur, we only award the first report that was received (provided that it can be fully reproduced).

  • Multiple vulnerabilities caused by one underlying issue will be awarded one bounty.

  • Social engineering (e.g. phishing, vishing, smishing) is prohibited.

  • Make a good faith effort to avoid privacy violations, destruction of data, and interruption or degradation of our service. Only interact with accounts you own or with explicit permission of the account holder.


Please see the structured bounty table in HackerOne. Our bounty table provides general guidelines, and all final decisions are at the discretion of ConsenSys.
