FinNexus Partners with Immunefi to Launch Bug Bounty

Do you think you caught a bug in FinNexus’ protocols? Now you can get rewarded for it!

The FinNexus team is glad to announce we have partnered with Immunefi, the leading bug bounty platform for smart contracts and DeFi projects, where security researchers review code, disclose vulnerabilities, get paid, and make crypto safer.

Together, we are now offering a bug bounty program which will be managed by Immunefi and financed by FinNexus. We are targeting the following assets:


Smart Contract:

Smart Contract:

Smart Contract:

Users who spot a bug will be rewarded for it according to Immunefi’s own classification of Vulnerabilities. The higher the severity of a risk, the more the bounty hunter will be rewarded, as shown below:

Smart Contracts and Blockchain

Critical USD 50 000–100 000

High USD 10 000–20 000

Medium USD 3 000–5 000

Low USD 700–1 000

Please be aware that we are mostly interested in the following types of issues:

Smart Contracts and Blockchain

  • Re-entrancy
  • Logic errors (including user authentication errors)
  • Solidity/EVM details not considered (including integer over-/under-flow and 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, block stuffing and 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

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

The following activities are prohibited by the 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
