Program Overview

KogeFarm is a low-fee, multi-chain yield aggregator/optimizer that automates reward harvesting and yield compounding across hundreds of farms from dozens of yield farm platforms. It was launched in May 2021 on the Polygon chain and is quickly expanding to others.

For more information about KogeFarm, please visit https://kogefarm.io/vaults.

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

  • Loss of user funds staked (principal) by freezing or theft

Rewards by Threat Level

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2.2. 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 following vulnerabilities are not eligible for a reward: Small difference between principal and vault shares due to rounding to 10^18 decimals.

In addition to Immunefi’s Vulnerability Severity Classification System, KogeFarm classifies the following vulnerabilities as follows. In case of discrepancy, the one below will be followed.


  • Theft of principal is critical if the possible theft is greater than USD 100000.
  • Freezing of principal is critical if it cannot be unfrozen, with impacted amounts greater than USD 100000.

KogeFarm requires KYC to be done for all bug bounty hunters submitting a report and wanting a reward. The information needed is the bug bounty hunter's face and document verification using https://kycaid.com/. The collection of this information will be done by the KogeFarm team.

Payouts are handled by the KogeFarm team directly and are denominated in USD. However, payouts are done in USDC.
