The Impossible Bug Bounty Program
Impossible Finance collaborates with Immunefi on the Impossible Bug Bounty Program!
Impossible Finance collaborates with Immunefi on the Impossible Bug Bounty Program! Further resources regarding Impossible Finance can be found on our website, https://impossible.finance/. The bug bounty program is focused around smart contracts and is mostly concerned with the loss of user funds and other smart contract risks.
Rewards by threat level
Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System. This is a simplified 5-level scale, with separate scales for websites/apps and smart contracts/blockchains. It encompasses everything from consequence of exploitation, to privilege required, to likelihood of a successful exploit.
Smart Contracts and Blockchain
Critical — — USD 50 000–10% of Funds at Risk (max est. USD 94 000)
High — — USD 20 000
Medium — — USD 5 000
Low — — USD 1 000
Smart Contract critical payouts have a maximum total payout of 10% of the funds that are directly potentially affected with a payout floor of USD50,000. The estimated maximum payout is based on the Total Value Locked (TVL) in the Impossible Finance but is explicitly only an estimate and only the actual active amount at the time of reporting will be considered. The actual active amount of staked funds can be found on http://impossible.finance/.
Payouts are handled by the Impossible Finance team directly and are denominated in USD. However, payouts are done in BUSD. For Critical payouts, up to 80% of the reward may be in the project token, IF.

The ImpossibleRouter01.sol smart contract is considered as out-of-scope of the bug bounty program.
Prioritized Smart Contract/Blockchain vulnerabilities
We are especially interested in receiving and rewarding vulnerabilities of the following types:
Re-entrancy
Logic errors
including user authentication errors
Solidity/EVM details not considered
including integer over-/under-flow
including unhandled exceptions
Trusting trust/dependency vulnerabilities
including composability vulnerabilities
Oracle failure/manipulation
Novel governance attacks
Economic/financial attacks
including flash loan attacks
Congestion and scalability
including running out of gas
including block stuffing
including susceptibility to frontrunning
Consensus failures
Cryptography problems
Signature malleability
Susceptibility to replay attacks
Weak randomness
Weak encryption
Susceptibility to block timestamp manipulation
Missing access controls / unprotected internal or debugging interfaces
Out of Scope & Rules
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)
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
The following activities are prohibited by 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
