Kiln DeFi enables non-custodial platforms to propose DeFi yield products (like lending supply or rwa distributor) where users can deposit any amount of ERC20 on a vault while remaining the only one able to access their staked assets.

Direct theft of any user funds, whether at-rest or in-motion, other than unclaimed yield

Permanent freezing of funds

Protocol insolvency

Theft of unclaimed yield

Permanent freezing of unclaimed yield

Temporary freezing of funds (> 2 days without taking into account possible oracle delay)

Direct theft of any commission, whether at-rest or in-motion

Griefing (e.g. no profit motive for an attacker, but damage to the users or the protocol)

Only the following impacts are accepted within this bug bounty program. All other impacts are not considered as in-scope, even if they affect something in the assets in scope table.

Rewards are distributed according to the impact of the vulnerability based on the [Immunefi Vulnerability Severity Classification System V2.3](https://immunefi.com/immunefi-vulnerability-severity-classification-system-v2-3/). 

__Reward Calculation for Critical Level Reports__

For critical smart contract bugs, the reward amount is 10% of the funds directly affected up to a maximum of USD 500 000. 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 100 000 is to be rewarded in order to incentivize security researchers against withholding a critical bug report.

__Repeatable Attack Limitations__

- 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. 

__Reward Calculation for High Level Reports__

- High vulnerabilities concerning theft/permanent freezing of unclaimed yield/royalties are rewarded within a range of USD 20 000 to USD 50 000 depending on the funds at risk, capped at the maximum high reward.  

- For High Smart Contract vulnerabilities that result in direct theft or permanent freezing of unclaimed yield, or the temporary freezing of unclaimed yield for more than 2 days (oracle timing should not be taken into account in this delay), the reward amount will be capped at 100% of the funds affected, up to a maximum of USD 50 000.  However, a minimum reward of USD 20 000 is to be rewarded in order to incentivize security researchers against withholding a bug report.   

__Reward Calculation for Medium Level Reports__

For Medium Smart Contract bugs, the reward amount is 10% of the commission funds directly affected up to a maximum of USD 20 000. 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 5 000 is to be rewarded in order to incentivize security researchers against withholding a bug report.

__Reward Payment Terms__

Payouts are handled by the Kiln team directly and are denominated in __USD__. However, payments are done in __USDC__ on __Ethereum__
