Euler’s $1 Million Bug Bounty Programme With Cantina Is Live

Building on the success of our recent code competition with 602 researchers, we're thrilled to continue our collaboration with Cantina to further fortify Euler v2's contracts and launch a $1 million bug bounty programme, now live.

Over the past year, we've worked closely with numerous security teams and individual researchers whose insights have helped us refine and strengthen both Euler v2’s contract design and security. The goal of this programme is to continue to work with the security community by inviting them to test, identify, report vulnerabilities and further enhance the security of the contracts. 

Following the imminent launch of Euler v2, this will be just one of the many ongoing security measures we’ll implement, as detailed in our security framework blog.

Scope

This bug bounty focuses on the vaults which are smart contract addresses returned by the verifiedArray() function of the following default perspectives:

The bug bounty covers the contracts in the master/main branch of the key repositories that the above vaults RELY ON:

Severity Levels & Rewards

We've structured our rewards based on the severity of the identified vulnerabilities:

  • Smart Contracts:
    • High Impact: Up to $1,000,000 (minimum payout: $200,000)
    • Medium Impact: Up to $200,000 (minimum payout: $50,000)
  • Web Interface:
    • Critical: $25,000
    • High: $5,000
    • Medium: $1,000

Rewards are calculated based on the economic impact of the vulnerabilities. For smart contract bugs, a minimum payout of $200,000 is guaranteed for high-severity findings.

Out of Scope

Certain areas are considered out of scope for this bug bounty:

  • Issues related to previously acknowledged or fixed bugs.
  • Findings based on outdated or unsupported contracts, scripts, or third-party integrations.
  • Non-security-related bugs such as UI glitches or performance issues.
  • Vulnerabilities affecting non-sensitive endpoints, outdated browsers, or plugins.
  • Issues involving actions controlled by Euler DAO entities are assumed to be trusted and are therefore out of scope.
  • In governed vaults, configuration mistakes made by the governor are out of scope.

Website-Specific

Only the official Euler V2 protocol launch site is within scope. Non-security bugs and certain vulnerabilities, such as clickjacking or CSRF on non-sensitive forms, are excluded.
