Program Overview

Holdefi is a decentralized open-source non-custodial money market protocol where users can participate as depositors or borrowers. Depositors provide liquidity to the market to earn a passive income, and everyone can borrow from this liquidity and repay it after a while. The Borrower must add collateral before borrowing any tokens. The value of the collateral should be greater than the value of the assets they want to borrow. This collateral is, in fact, a guarantee that they will repay the borrowed assets.

For more information about Holdefi, please visit their website at https://holdefi.com/.

The bug bounty program is focused on the prevention of negative impacts to its smart contracts. Please see the Impacts in Scope section below for more information on the specific impacts it wishes to prevent.

Rewards by Threat Level

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System. 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.

Payouts are handled by the Holdefi team directly and are denominated in USD. All payouts are done in BUSD or USDC, at the discretion of the Holdefi team. Bug bounty hunters must indicate whether the address they are providing is an Ethereum address or one on the Binance Smart Chain (BSC).
