Program Overview

NFTfi is the leading liquidity protocol for NFTs. NFTfi allows NFT owners to use the assets (NFTs) they own to access the liquidity they need by receiving secured loans from liquidity providers, peer-to-peer, in a completely trustless manner.

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.
