Event details

Rewards

Vulnerability reports will be scored using the CVSS v3 standard. The reward amounts for different types of vulnerabilities are:

Critical (CVSS 9.0–10.0)

  • $5,000 - $50,000

Major (CVSS 7.0–8.9)

  • $2,500 - $5,000​

Medium (CVSS 4.0–6.9)

  • $1,000 - $2,500

Low (CVSS 1.0–3.9)

  • $500 - $1,000

Rewards will be awarded at the sole discretion of Liquity AG. Quality of the report and reproduction instructions can impact the reward. Rewards are denominated and paid out in USD. If both parties agree, rewards can also be paid out in crypto.

Reporting a Vulnerability

Please responsibly disclose any findings to the development team, following these instructions:

  • In order to report a vulnerability, please write an email to security@liquity.org with [SECURITY DISCLOSURE] in the subject of the email.
  • For sensitive vulnerabilities, please the encrypt the email using this PGP key (Fingerprint: 3F21 FFCD AD2A 7D5B 8E11 3198 FCE7 91AE 1A6F 4793).
  • Team will make their best effort to reply in a timely manner and provide a timeline for resolution.
  • Please include a detailed report on the vulnerability with clear reproduction steps. The quality of the report can impact the reward amount.

Failure to do so will result in a finding being ineligible for any bounties.

Scope

In scope for the bug bounty are all the smart contract components of the Liquity protocol. They can be found in the following repositories:

Solidity code under the contracts directory:

  • Excluding contracts/Dependencies
  • Excluding contracts/LPRewards/Dependencies

The contract StabilityPool.sol is not yet released and therefore out of scope. Nevertheless, team have published the interface for it, Interfaces/IStabilityPool.sol, which includes descriptions for the contract's purpose and for each function. A high level description can also be found in the README file

Out of scope

  • Any frontend applications or client-side code interacting with the contracts, as well as testing code.
  • Mismatch of the functionality of the contracts and outdated spec documents.

Areas of interest

These are some examples of vulnerabilities that would be interesting:

  • Stealing tokens or manipulating the token generation process.
  • Locking or freezing any of the Liquity contracts.
  • Griefing attacks: is it possible to block liquidations, redemptions, borrower operations, rewards distributions, etc?
  • Do the desired constraints on borrower operations hold?
  • Flash loan exploits
  • LQTY token exploits involving the LockupContracts

Eligibility

Terms for eligible bounties:

  • Only unknown vulnerabilities will be awarded a bounty; in case of duplicate reports, the first report will be awarded the bounty.
  • Public disclosure of the vulnerability, before explicit consent from Liquity AG to do so, will make the vulnerability ineligible for a bounty.
  • Attempting to exploit the vulnerability in a public Ethereum network will also make it ineligible for a bounty.
