Program's Out of Scope information

These impacts are out of scope for this bug bounty program.

All Categories

  • Impacts requiring attacks that the reporter has already exploited themselves, leading to damage
  • Impacts caused by attacks requiring access to leaked keys/credentials
  • Impacts caused by attacks requiring access to privileged addresses (governance, strategist) except in such cases where the contracts are intended to have no privileged access to functions that make the attack possible
  • Impacts relying on attacks involving the depegging of an external stablecoin where the attacker does not directly cause the depegging due to a bug in code
  • Mentions of secrets, access tokens, API keys, private keys, etc. in Github will be considered out of scope without proof that they are in-use in production
  • Best practice recommendations
  • Feature requests
  • Impacts on test files and configuration files unless stated otherwise in the bug bounty program

Smart Contracts

  • Incorrect data supplied by third party oracles
    • Not to exclude oracle manipulation/flash loan attacks
  • Impacts requiring basic economic and governance attacks (e.g. 51% attack)
  • Lack of liquidity impacts
  • Impacts from Sybil attacks
  • Impacts involving centralization risks
  • Best practice recommendations
  • Impacts involving unsupported tokens (tokens with transfer hooks (e.g. ERC777), fee-on-transfer tokens, blocklistable tokens, and non-standard ERC20 or ERC721 tokens)
  • Impacts involving griefing and/or denial of service in the Collateral Liquidator due to using unsupported tokens
  • Impacts involving the Pool or Collateral Liquidator deployed with misconfigured or malicious parameters
  • Theft of unclaimed yield by speculation on loan repayment or liquidation
  • Freezing of tokens or funds due to unsupported airdrops to assets in escrow
  • Interest-free loans caused by integer truncation due to short duration, small principal, or small interest rate
