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.

This bug bounty program is focused around the Enzyme Finance smart contracts and app 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, 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 vulnerabilities is capped at 10% of the funds at risk based on the vulnerability reported.

All web and app 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 $250,000.

Assets in Scope

Only web/app vulnerabilities that directly affect the listed web/app assets are accepted within the bug bounty program. All others are out-of-scope.

Prioritized Vulnerabilities

We are especially interested in receiving and rewarding vulnerabilities of the following types:

Smart Contracts/Blockchain:

  • Re-entrancy
  • Logic errors
    • including user authentication errors
  • Solidity/EVM details not considered
    • including integer over-/under-flow
    • including unhandled exceptions
  • Trusting trust/dependency vulnerabilities
    • including composability vulnerabilities
  • Oracle failure/manipulation
  • Novel governance attacks
  • Economic/financial attacks
    • including flash loan attacks
  • Congestion and scalability
    • including running out of gas
    • including block stuffing
    • including susceptibility to frontrunning
  • Consensus failures
  • Cryptography problems
    • Signature malleability
    • Susceptibility to replay attacks
    • Weak randomness
    • Weak encryption
  • Susceptibility to block timestamp manipulation
  • Missing access controls / unprotected internal or debugging interfaces

Websites and Apps

  • Remote Code Execution
  • Trusting trust/dependency vulnerabilities
  • Vertical Privilege Escalation
  • XML External Entities Injection
  • Horizontal Privilege Escalation
  • Stored XSS
  • Reflective XSS with impact
  • CSRF (reports of CSRF must include a demonstration of impact)
  • Direct object reference
  • Session fixation
  • Insecure Deserialization
  • Direct object reference
  • DOM XSS

Out of Scope & Rules

The following vulnerabilities are excluded from the rewards for this bug bounty program:

  • Attacks that the reporter has already exploited themselves, leading to damage
  • Attacks requiring access to leaked keys/credentials
  • Attacks requiring access to privileged addresses (governance, strategist)

Smart Contracts and Blockchain

  • Incorrect data supplied by third party oracles
    • Not to exclude oracle manipulation/flash loan attacks
  • Basic economic governance attacks (e.g. 51% attack)
  • Lack of liquidity
  • Best practice critiques
  • Sybil attacks

Websites and Apps

  • Theoretical vulnerabilities without any proof or demonstration
  • Content spoofing / Text injection issues
  • Self-XSS
  • Captcha bypass using OCR
  • CSRF with no security impact (logout CSRF, change language, etc.)
  • Missing HTTP Security Headers (such as X-FRAME-OPTIONS) or cookie security flags (such as “httponly”)
  • Server-side information disclosure such as IPs, server names, and most stack traces
  • Vulnerabilities used to enumerate or confirm the existence of users or tenants
  • Vulnerabilities requiring unlikely user actions
  • URL Redirects (unless combined with another vulnerability to produce a more severe vulnerability)
  • Lack of SSL/TLS best practices
  • DDoS vulnerabilities
  • Attacks requiring privileged access from within the organization
  • Feature requests
  • Best practices
  • Internal SSRF
  • Path Traversal
  • SPF Configuration Problems

The following activities are prohibited by bug bounty program:

  • Any testing with mainnet or public testnet contracts; all testing should be done on private testnets
  • Any testing with pricing oracles or third party smart contracts
  • Attempting phishing or other social engineering attacks against our employees and/or customers
  • Any testing with third party systems and applications (e.g. browser extensions) as well as websites (e.g. SSO providers, advertising networks)
  • Any denial of service attacks
  • Automated testing of services that generates significant amounts of traffic
  • Public disclosure of an unpatched vulnerability in an embargoed bounty
