Contrax

Contrax is a Decentralized Finance (DeFi) web application that allows users to farm real yield assets, and have them compound automatically. Users can also create tokens and pools in just a few clicks. Our goal is to lower the barrier of entry to DeFi by ensuring an easy onboarding experience, and only listing farms with projects that earn real revenue instead of relying on token inflation.

Program's Out of Scope information

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)
  • Attacks that are the same exploit over multiple contracts would be considered as one exploit

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
  • Centralization risks

The following activities are prohibited by this 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
  • Any vulnerability which leads to assets transferred between Contrax deployed smart contacts (example: hacker finds a way to call earn and harvest early. This technically leads to funds moving, but it is within our intended flow)
