Extra Finance Documentation

Rewards are distributed according to the impact the vulnerability could otherwise cause based on the Impacts in Scope table further below. 

__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 15 000 is to be rewarded in order to incentivize security researchers against withholding a bug report.  

__Repeatable Attack Limitations__

In cases of repeatable attacks for smart contract bugs, only the first attack will be counted, regardless of whether the smart contract is upgradable, pausable, or killable.

__Previous Audits__

Extra Finance has provided these completed audit review reports for reference. Any unfixed vulnerability mentioned in these reports are not eligible for a reward.

__Proof of Concept (PoC) Requirements__

A PoC is required for the following severity levels:
- Smart Contract - Critical
- Smart Contract - High
- Smart Contract - Medium

All PoCs submitted must comply with the Immunefi-wide [PoC Guidelines and Rules.](https://immunefisupport.zendesk.com/hc/en-us/articles/9946217628561-Proof-of-Concept-PoC-Guidelines-and-Rules) Bug report submissions without a PoC when a PoC is required will not be provided with a reward.

__Reward Payment Terms__

As part of the bug bounty matching program, Optimism will contribute __52,500__ OP tokens to match the rewards offered by Extra Finance. This means that for every reward paid out by Extra Finance to a security researcher, Optimism will provide an additional, matching reward, in OP tokens. The total reward pool for this program is __52,500__ OP tokens.

Payouts are handled by the Extra Finance team directly and are denominated in USD. However, payments are done in USDC.
