BENQI is a decentralized finance protocol on Avalanche that lets users lend, borrow, stake, and earn yield — either by supplying assets for interest or by staking AVAX to get a liquid staking token sAVAX, which remains usable in DeFi.  Since its 2021 launch, it has grown into a full DeFi ecosystem combining liquidity markets, liquid staking, and validator bootstrapping.

Taking state-modifying authenticated actions (with or without blockchain state interaction) on behalf of other users without any interaction by that user, such as, changing registration information, commenting, voting, making trades, withdrawals, etc.

Rewards are distributed according to the impact of the vulnerability based on the [Immunefi Vulnerability Severity Classification System V2.2](https://immunefi.com/immunefi-vulnerability-severity-classification-system-v2-2). This is a simplified 5-level scale, with separate scales for websites/apps and smart contracts/blockchains, encompassing everything from consequence of exploitation to privilege required to likelihood of a successful exploit.

The final reward amount for critical smart contract and blockchain vulnerabilities is capped at 10% of the economic damage funds at risk based on the vulnerability reported with a payout floor of __USD 50 000__.  All smart contract reports must come with a Proof of Concept (PoC) showing impact. Reports without a PoC will be automatically rejected.

All web and app bug reports must come with a Proof of Concept (PoC) showing impact. Reports without a PoC will be automatically rejected.

Payouts are handled by the __BENQI__ team directly and are denominated in USD. Payouts are done in __USDC__ or __USDT__ for High level bug reports. For payouts __USD 50 000__ and above, up to 80% of the payout may be done in __$Qi__.
