Program Overview

Enzyme Finance, formerly known as Melon Protocol, is an Ethereum-based protocol for decentralized on-chain asset management. It is a protocol for people or entities to manage their wealth & the wealth of others within a customizable and safe environment. Enzyme empowers anyone to set up, manage and invest in customized on-chain investment vehicles.

More information about Enzyme Finance can be found in their docs and also here in the additional V4 docs. See especially the Known Risks & Mitigations.

This bug bounty program is focused around the Enzyme Finance smart contracts and is primarily concerned with the loss of user funds.

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 encompassing everything from consequence of exploitation to privilege required to likelihood of a successful exploit.

The final reward amount for critical smart contract vulnerabilities is capped at 10% of the funds at risk based on the vulnerability reported.

All bug reports must come with a PoC. If a bug report does not have a PoC it will be rejected with instructions to provide a PoC

All payouts are done by the Enzyme Finance team directly and are denominated in USD. Payouts are done in USDC up to USD $400,000.
