We invite all white hat hackers to join the hunt on ether.fi audit competition

All experience levels are welcome; whether you are a seasoned security veteran or an amateur, show us what you got! Prizes will be given based on the severity level of each vulnerability found.

About the Competition

Starting Nov 6th a new vault will open in the Hats dApp — ”ether.fi” Participants can check the contracts in scope and start searching for bugs.

ether.fi is a decentralized, non-custodial delegated staking protocol with a Liquid Staking Derivative token. One of the distinguishing characteristics of ether.fi is that stakers control their keys. The ether.fi mechanism also allows for the creation of a node services marketplace where stakers and node operators can enroll nodes to provide infrastructure services.

Stay up-to-date with the competition, chat with the team, and get your questions answered by joining the dedicated Discord channel on the Hats server.
All audit reports will be published in our Discord on the day of the competition. Don’t miss the latest updates and insights — join now and be the first to know!

  • Direct theft of any user funds, whether at rest or in motion
  • Long-term freezing of user funds
  • Theft or long-term freezing of unclaimed yield or other assets
  • Protocol insolvency

Medium Severity

The total prize pool for Medium severities will be ~$10,800 in USDC
The total High-severity reward will be divided between all accepted issues.

However, there is a max reward cap of $2k for a single submission; each new issue gets 1 point.

A 10% service fee is already deducted from this prize pool.

Medium severity vulnerability description:

Issues that lead to an economic loss but do not lead to direct loss of on-chain assets. Examples are:

  • Gas griefing attacks (make users overpay for gas)
  • Attacks that make essential functionality of the contracts temporarily unusable or inaccessible
  • Short-term freezing of user funds

Low severity

The total prize pool for Low severities will be ~$3,600 in USDC
The total High-severity reward will be divided between all accepted issues.

However, there is a max reward cap of $500k for a single submission; each new issue gets 1 point.

A 10% service fee is already deducted from this prize pool.

Low severity vulnerability description:

  • Issues where the behavior of the contracts differs from the intended behavior (as described in the docs and by common sense), but no funds are at risk.

Limitations

Reporters will not receive a bounty for any known issue, such as:

  • Issues mentioned in any previous audit reports
  • Vulnerabilities that were already made public (either by HATs or by a third party)
  • “Centralization risks” that are known and/or explicitly coded into the protocol (e.g. an administrator can upgrade crucial contracts and steal all funds)
  • Attacks that require access to leaked private keys or trusted addresses
  • Issues/contracts mentioned in the out-of-scope section

Submission Guidelines — High/Medium/Low severities:

General Information:

  • The Hats team will create a new repository called “Ether_fi Competition” under the Hats.finance organization on GitHub. The repository will be kept private until the competition starts. Hats bot will fork it on the first submission. To participate, security researchers must submit their findings on-chain, and an automatic GitHub issue will be generated in the forked repository.
  • How it Works: Video Explanation

SUBMISSION GUIDELINES:

  • Submissions should be made using our Dapp.
  • You can submit one on-chain submission mentioning all issues found on the repo.
  • All new submissions will be created on Hats forked repo on Hats: Hats GitHub

Report Format:

  • Please send a plain ASCII description in the following format:
  • [TITLE]: A short description of the issue.
  • SEVERITY: Either High, Medium, or Low (as per the rules).
  • Submission should contain at least one test demonstrating the problem and, if possible, a possible fix.

Report Template:

  • Description: Describe the context and the effect of the vulnerability.
  • Attack scenario: Describe how the vulnerability can be exploited.
  • Attachment:
  • Proof of Concept (PoC) File: Provide a file containing a proof of concept (PoC) that demonstrates the vulnerability.
  • Revised Code File (Optional): If possible, provide a second file containing the revised code that offers a potential fix for the vulnerability. This file should include:
  • Comment with a clear explanation of the proposed fix.
  • The revised code with suggested changes.
  • Add any additional comments or explanations clarifying how the fix addresses the vulnerability.
  • Recommendation: Describe a patch or potential fix for the vulnerability.

***Due to the nature of the audit competition mechanism, the report will not be encrypted.***

Evaluation:

  • The first participant to submit an issue following guidelines gets a bounty for that issue (issues already received or out of scope will not be rewarded).
  • The competition starts on Nov 6th at 14:00 GMT and ends on NOV 16th at 14:00 GMT.
  • Issues that we are aware of (as witnessed by any open issues in the repository) will not be eligible for the bug bounty.

Compensation and Impact

A prize pool of ~$72K In USDC and NFT rewards from our hacker collection will be distributed among security researchers who submit eligible vulnerability disclosures.

Compensation payment timeline:

  • Ten days after the competition ends, we will announce a winner list.
  • Alongside the winner announcement post, submitters can send disputes to the committee team and request clarification. They can also involve the Hats security team in the process. The goal is to facilitate honest and professional debate regarding disputed submissions.
  • Between 7–14 days after the announcement, we will publish a split contract where the winners can claim their rewards.
  • HATS Service Fee: A 10% deduction from the payout will always be allocated as the service fee.

Security researchers play a crucial role in fostering trust and confidence in Web3 technologies, paving the way for mass adoption. By participating in this competition, security researchers can gain recognition for their work, raise their profile, and make valuable connections in the Web3 security ecosystem. Ultimately, they can contribute to creating a more secure and equitable community.
