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

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.
