Katana
Katana is a chain designed specifically for DeFi. It rethinks DeFi to offer what users care about most: deeper liquidity and higher yields, all in a sustainable way. This happens through mechanisms to ensure that all liquidity on Katana is absorbed in only one lending protocol (Morpho), one spot DEX (Sushi), which are the core applications on Katana with hundreds of applications building on top of them. This is achieved with a unique approach to maximizing yield that can be used as incentives on the core applications, including from Vault Bridge, sequencer fees, and Agora USD revenue.
Katana has deeply embedded, user-focused interoperability, using Agglayer for all users to onboard seamlessly. Katana uses ZK proofs to validate state transitions, allowing users to exit the chain without long wait periods.
Katana provides rewards in USDC on Ethereum, denominated in USD.
Smart Contract
Reward amount is 10% of the funds directly affected up to a maximum of $80,000.
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 80,000. 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.
The amount of funds at risk will be calculated with the impact of the first attack being at 100% and then a reduction of 25% from the amount of the first attack for every 300 blocks the attack needs for subsequent attacks from the first attack, rounded down.
High vulnerabilities concerning theft/permanent freezing of unclaimed yield/royalties are rewarded within a range of USD 3,000 to USD 15,000 with the reward calculated based on 100% of the funds at risk, though 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.
Payouts are handled by the Katana 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.
Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2.3.
Katana adheres to Category 3: Approval Required. This Policy determines what information researchers are allowed to make public from their submitted bug reports.
Katana 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.

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.
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:
