Rewards by Threat Level
Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2.2. This is a simplified 5-level scale, with separate scales for websites/apps, smart contracts, and blockchains/DLTs, focusing on the impact of the vulnerability reported.
Critical Severity smart contract bug reports must come with a PoC with an end-effect impacting an asset-in-scope in order to be considered for a reward. Explanations and statements are not accepted as PoC and code is required.
Known issues highlighted in the following audit reports are considered out of scope: -https://github.com/HalbornSecurity/PublicReports/blob/master/Solidity%20Smart%20Contract%20Audits/NFTfi_Bundles_Airdrop_Smart_Contract_Security_Audit_Report_Halborn_Final.pdf
Payouts are handled by the NFTfi team directly and are denominated in USD. However, payouts are done in USDC.
