SynFutures 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 web/apps bug reports will be rewarded with USD 10 000, only if the impact leads to:

- A loss of funds involving an attack that does not require any user action
- Private key or private key generation leakage leading to unauthorized access to user funds 

All other impacts that would be classified as Critical would be rewarded a flat amount of USD 5 000. The rest of the severity levels are paid out according to the Impact in Scope table.  

__Reward Payment Terms__

Payouts are handled by the SynFutures 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.
