Furucombo Bug Bounty Program

Program Overview

The Furucombo team combines the merits of every kind of DeFi protocol to create the most comprehensive DeFi aggregator platform on Ethereum & Polygon. The structure of Furucombo is composed of proxy contracts and handler contracts. The security of our system is of paramount importance to us. While we continue conducting professional audits for the whole system, a bug bounty program is necessary to also ensure the platform’s safety.

This program is intended to work with independent security researchers across the globe and set out our definition of good faith in the context of finding and reporting vulnerabilities, as well as what users can expect from us in return. Should you encounter a security vulnerability in one of our products, we want to hear from you. We believe that the Furucombo ecosystem will be further bolstered with support from our community.

This bug bounty program is focused on smart contracts and is focused on preventing:

  • Loss of user funds during a transaction by freezing or theft
  • Loss of user funds by theft of approved smart contracts
  • Theft of unclaimed yield
  • Freezing of unclaimed yield unable to call smart contract
  • Smart contract gas drainage
  • Smart contract failure to deliver promised returns
  • Interaction with unauthorized handler logic

Note: Other issues found outside of the locations mentioned above, will be considered on a case by case basis, please, reach out to the Furucombo development team for clarification.


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.

Smart Contracts and Blockchain Vulnerabilities

  • Critical: Up to 250,000USD
  • High: 5,000USD
  • Medium: 2,000USD
  • Low: 1,000USD

All Low, Medium, High and Critical Smart Contract bug reports require a proof of concept to be eligible for a reward.

Critical smart contract vulnerabilities are capped at 10% of economic damage, primarily taking into consideration funds at risk & PR and branding aspects — at the discretion of the team. However, there is a minimum reward of 50,000USD.

Any vulnerabilities found in https://github.com/dinngodev/furucombo-contract/tree/master/audit are not eligible for reward.

FURUCOMBO requires KYC to be completed for all bug bounty hunters submitting a report and requesting a reward. The information needed are name and email address. The collection of this information will be handled by the Furucombo team.

Payouts are handled by the Furucombo team directly, and are denominated in USD. Payments may be done in ETH, DAI, USDC and COMBO, with the ratio at the discretion of the team.
