UMA Bug Bounty Program

Security of the platform is our highest priority. All contract code and balances are publicly verifiable, and security researchers are eligible for a bug bounty for reporting undiscovered vulnerabilities.


UMA encourages the community to audit our contracts and security; we also encourage the responsible disclosure of any issues. The bug bounty program is intended to recognize the value of working with the community of independent security researchers, and sets out our definition of good faith in the context of finding and reporting vulnerabilities, as well as what you can expect from us in return.

The contracts in the common directory and the oracle directory of the /protocol repo have been carefully audited by OpenZeppelin. The audit report can be found here.

The contracts in the financial-templates directory have been audited by OpenZeppelin. The audit report can be found here.

Updates to the Expiring Multiparty contracts and flash loan mitigations for the voting contracts have been audited by OpenZeppelin. The audit report can be found here.

The Perpetual Multiparty and Optimistic Oracle have been audited by OpenZeppelin. The audit report can be found here.

Additionally, OpenZeppelin audits incremental upgrades to UMA's contracts on a continuous basis. The continuous audit report can be found here.


UMA offers substantial rewards for discoveries that can prevent the loss of assets, the freezing of assets, or harm to users.

All rewards will be paid in $UMA, and the amount of compensation will vary depending on bug severity. Reward amounts typically correspond to severity in the following manner.

SeverityReward amount in USD

Severity is calculated according to the OWASP risk rating model based on Impact and Likelihood.

If you comply with the policies below when reporting a security issue to us, we will not initiate a lawsuit or law enforcement investigation against you in response to your report.

We ask that you:

  • Report any vulnerability you’ve discovered promptly.
  • Avoid violating the privacy of others, disrupting our systems, destroying data, or harming user experience.
  • Use only to discuss vulnerabilities with us.
  • Keep the details of any discovered vulnerabilities confidential until they are publicly announced by the UMA Foundation on the documentation website.

  • Not engage in blackmail, extortion, or any other unlawful conduct.
  • Not be a current or former UMA Foundation employee, vendor, contractor, or the employee of an UMA vendor or contractor.

Public disclosure of the bug or the indication of an intention to exploit it on Mainnet will make the report ineligible for a bounty. If in doubt about other aspects of the bounty, most of the Ethereum Foundation bug bounty program rules will apply.
