Critical Reward Calculation

Mainnet assets:

Reward amount is 10% of the funds directly affected up to a maximum of:

$94,000

Minimum reward to discourage security researchers from withholding a bug report:

$50,000

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2.2. This is a simplified 5-level scale, with separate scales for websites/apps and smart contracts/blockchains, encompassing everything from consequence of exploitation to privilege required to likelihood of a successful exploit.

Smart Contract critical payouts have a maximum total payout of 10% of the funds that are directly potentially affected with a payout floor of USD 50 000. 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 https://farms.impossible.finance/farms.

KYC

Country of residence is required for KYC process

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.

Program Overview

Impossible Finance uses decentralised financial protocols to give everyone the same access to financial products, which were previously only available to institutions and select individuals. Impossible Finance has a vision to level the playing field by building a fair, more accessible open financial system for all.

Further resources regarding Impossible Finance can be found on their website, https://impossible.finance/.

The bug bounty program is focused around its smart contracts and is mostly concerned with the loss of user funds and other smart contract risks.

KYC not required

No KYC information is required for payout processing.

Proof of Concept

Proof of concept is always required for all severities.

Prohibited Activities

Default prohibited activities
  • Any testing on mainnet or public testnet deployed code; all testing should be done on local-forks of either public testnet or mainnet
  • 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 that are executed against project assets
  • Automated testing of services that generates significant amounts of traffic
  • Public disclosure of an unpatched vulnerability in an embargoed bounty
  • Any other actions prohibited by the Immunefi Rules

Feasibility Limitations

The project may be receiving reports that are valid (the bug and attack vector are real) and cite assets and impacts that are in scope, but there may be obstacles or barriers to executing the attack in the real world. In other words, there is a question about how feasible the attack really is. Conversely, there may also be mitigation measures that projects can take to prevent the impact of the bug, which are not feasible or would require unconventional action and hence, should not be used as reasons for downgrading a bug's severity.

Therefore, Immunefi has developed a set of feasibility limitation standards which by default states what security researchers, as well as projects, can or cannot cite when reviewing a bug report.
