Anvil is a decentralized finance (DeFi) protocol for the issuance of fully secured credit. The protocol's Ethereum-based smart contracts allow users to deposit collateral in a vault, issue letters of credit, and supply assets to staking pools.

Theft of gas

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

Permanent freezing of funds

Contract fails to deliver promised returns, but doesn't lose value

Temporary freezing of funds

Smart contract unable to operate due to lack of token funds

Manipulation of governance voting result deviating from voted outcome and resulting in a direct change from intended effect of original results

Unbounded gas consumption

Protocol insolvency: Defined as value in the CollateralVault < cumulative account balances within CollateralVault or an active LetterOfCredit not being redeemable by the beneficiary for its face value for any reason other than liquidation exchange rate

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 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 25,000 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 are rewarded within a range of $10,000 to $25,000 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 calendar month 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.

__Reward Payment Terms__

Payouts are handled by the Anvil team directly and are denominated in **USD**. However, payments are done in **USDT** on **Ethereum**.
