Program's Out of Scope information
The following vulnerabilities are excluded from the rewards for this bug bounty program:
- Attacks that the reporter has already exploited themselves, leading to damage
- Attacks requiring access to leaked keys/credentials
- Attacks requiring access to privileged addresses (governance, strategist)
Smart Contracts and Blockchain
- Incorrect data supplied by third party oracles
- Not to exclude oracle manipulation/flash loan attacks
- Basic economic governance attacks (e.g. 51% attack)
- Lack of liquidity
- Best practice critiques
- Sybil attacks
- Centralization risks
- Specifically for the crosschaincanonicalbase.sol contract: This contract is outdated bridging code for Layer 2 alAssets, however, the layer 2 alAssets were upgraded and still contain state variables related to this code, therefore the code has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.
The following activities are prohibited by this bug bounty program:
- Any testing with mainnet or public testnet contracts; all testing should be done on private testnets
- Any testing with pricing oracles or third party smart contracts
- Attempting phishing or other social engineering attacks against our employees and/or customers
- Any testing with third party systems and applications (e.g. browser extensions) as well as websites (e.g. SSO providers, advertising networks)
- Any denial of service attacks
- Automated testing of services that generates significant amounts of traffic
- Public disclosure of an unpatched vulnerability in an embargoed bounty
