Out of scope

Program's Out of Scope information
  • Best practice recommendations
  • Problems caused by L1 Gas Pricing
  • Logic errors with rebase tokens and interest-bearing tokens
  • Attacks related to deposit and withdraw limits
  • Issues that affect geth (upstream) and are not caused by changes made in the scroll implementation
  • Freezing of own funds due to mistaken operation
  • Throttling or suppression of operations without loss of user funds
Default Out of Scope and rules

Blockchain/DLT specific

  • 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

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 (including, but not limited to: governance and strategist contracts) without additional modifications to the privileges attributed
  • 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
  • Impacts requiring phishing or other social engineering attacks against project's employees and/or customers
