Documentation

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 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 critical bug report.

For critical smart contract bugs on testnet assets, the reward is paid as a flat amount of USD 5 000. This is because there are no actual funds at risk on the testnet, hence limits objective calculation. 

__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. 
- 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.

__Reward Calculation for High Level Reports__

- High impacts concerning theft/permanent freezing of unclaimed yield/royalties are rewarded within a range of USD 3500  to USD 5000  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. 

__Reward Payment Terms__

Payouts are handled by the XOXNO team directly and are denominated in USD. However, payments are done in USDC on ETH.

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.
