Felix provides rewards in USDC on Ethereum, denominated in USD.
Smart Contract
Mainnet assets: Reward amount is 10% of the funds directly affected up to a maximum of $100,000
Minimum reward to discourage security researchers from withholding a bug report: $20,000
For critical smart contract bugs, the reward amount is 10% of the funds directly affected up to a maximum of USD 100,000. The calculation of the amount of funds at risk is based on the time and date the bug report is submitted. However, a minimum reward of USD 20,000 is to be rewarded in order to incentivize security researchers against withholding a critical bug report.
If the smart contract where the vulnerability exists can be upgraded or paused, only the initial attack will be considered for a reward. This is because the project can mitigate the risk of further exploitation by upgrading or pausing the component where the vulnerability exists. The reward amount will depend on the severity of the impact and the funds at risk.
For critical repeatable attacks on smart contracts that cannot be upgraded or paused, the project will consider the cumulative impact of the repeatable attacks for a reward. This is because the project cannot prevent the attacker from repeatedly exploiting the vulnerability until all funds are drained and/or other irreversible damage is done. Therefore, this warrants a reward equivalent to 10% of funds at risk, capped at the maximum critical reward.
High vulnerabilities concerning theft/permanent freezing of unclaimed yield/royalties are rewarded within a range of USD 4,000 to USD 10,000 depending on the funds at risk, capped at the maximum high reward.
In the event of temporary freezing, the reward doubles from the full frozen value for every additional 24h that the funds are temporarily frozen, up until a max cap of the high reward. This is because as the duration of the freezing lengthens, the potential for greater damage and subsequent reputational harm intensifies. Thus, by increasing the reward proportionally with the frozen duration, the project ensures stronger incentives for bug disclosure of this nature.
Payouts are handled by the Felix Protocol team directly and are denominated in USD. However, payments are done in USDC on Ethereum.
The calculation of the net amount rewarded is based on the average price between CoinMarketCap.com and CoinGecko.com at the time the bug report was submitted. No adjustments are made based on liquidity availability.
Felix Protocol adheres to the Primacy of Impact for the following impacts:
Primacy of Impact means that the impact is prioritized rather than a specific asset. This encourages security researchers to report on all bugs with an in-scope impact, even if the affected assets are not in scope.
When submitting a report on Immunefi's dashboard, the security researcher should select the Primacy of Impact asset placeholder. If the team behind this project has multiple programs, those other programs are not covered under Primacy of Impact for this program. Instead, check if those other projects have a bug bounty program on Immunefi.
If the project has any testnet and/or mock files, those will not be covered under Primacy of Impact.
All other impacts are considered under the Primacy of Rules, which means that they are bound by the terms and conditions set within this program.
A PoC, demonstrating the bug's impact, is required for this program and has to comply with the Immunefi PoC Guidelines and Rules.
Proof of concept is always required for all severities.
Bug reports covering previously-discovered bugs (listed below) are not eligible for a reward within this program. This includes known issues that the project is aware of but has consciously decided not to "fix", necessary code changes, or any implemented operational mitigating procedures that can lessen potential risk.
ETH_GAS_COMPENSATION set to 0. Due to the nature of the HyperEVM chain, this gas compensation is not required to still keep liquidations incentivised also considering that the COLL_GAS_COMPENSATION is not capped at 2 ether anymore.
Currently we are not including LST tokens therefore the fetchRedemption price mechanism has been excluded by the code. In case we'll include LSTs we will proceed with reintegrating this price logic.
The list below includes the issues arisen from Liquity V2 audits. The ones closed as accepted can be considered accepted by us as well. For what concerns the Cantina competition audit, it is assumed that we acknowledge all the findings.
The list below includes the security assessments performed directly on Felix itself. Also in this case, what is considered acknowledged does not represent a valid finding for the bug bounty program.
Felix Protocol's completed audit reports can be found at https://usefelix.gitbook.io/felix-docs/advanced/smart-contract-audits. Any unfixed vulnerabilities mentioned in these reports are not eligible for a reward.
The submission of KYC information is a requirement for payout processing.
Participants must adhere to the Eligibility Criteria.
Category 3: Approval Required
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
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.
