Out of scope

Program's Out of Scope information
  • Best practice critiques
  • Specifically for the crosschaincanonicalbase.sol contract: This contract is outdated bridging code for Layer 2 alAssets, however, the layer 2 alAssets were upgraded and still contain state variables related to this code, therefore the code has not been stripped from the Layer 2 alAssets. The crosschaincanonicalbase.sol contract is out of scope, EXCEPT for any bugs that would allow anyone besides a trusted admin/multisig to access the functions, or any issues with the current implementation of the bridge/L2 token (alchemicalTokenBase) created by this contract.
Default Out of Scope and rules

Smart Contract 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
