Assets in Scope
Impacts in Scope
Critical
Direct theft of user funds, whether at-rest or in-motion, other than unclaimed yield
Critical
Access control is bypassed, including privilege escalation
High
Governance voting result manipulation
High
Permanent freezing of funds
High
Permanent denial of service (smart contract is made unable to operate)
High
Theft of unclaimed yield / Permanent freezing of unclaimed yield - Impact severity is determined by potential yield lost
High
Temporary freezing of funds - Impact severity depends on funds at risk
Medium
Smart contract unable to operate due to lack of token funds
Medium
Griefing (e.g. no profit motive for an attacker, but damage to the users or the protocol)
Medium
Theft of gas
Medium
Unbounded gas consumption
Low
Contract fails to deliver promised returns, but doesn't lose value

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
- Attacks requiring access to leaked keys/credentials
- 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 on test files and configuration files unless stated otherwise in the bug bounty program
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)
- Susceptibility to block timestamp manipulation
- Lack of liquidity
- Best practice critiques
- Sybil attacks
- ERC mandated behaviors
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
