Program Overview

Autofarm is the first cross-chain yield aggregator that operates on Binance Smart Chain (BSC) and Huobi ECO Chain (HECO). Autofarm enables users to get the best return on their assets from yield farming pools by simply staking in Autofarm vaults. With dynamic harvesting, Autofarm compounds staked assets in our vaults automatically by using algorithmically profitable strategies at optimal compounding intervals. This custom optimizing function was built in-house to enable only the best yields for Autofarm users.

Compounding events on Autofarm occur on a daily basis, reaching a frequency of up to 170x a day for certain vaults. This automated process makes it possible for users to reap greater yields with a fraction of the effort required as there is no need for manual harvesting on any individual farming pools.

Together, Autofarm’s compounding strategies maximise APYs across multiple different yield farming protocols to achieve the most efficient capital returns. Users can just sit back, relax, and leave the hard work to us.

For more information, please see AutoFarm’s documentation, available at

The bug bounty program is focused around Autofarm’s smart contracts and the prevention of 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.

Payouts are handled by the Autofarm team directly and are denominated in USD. However, payouts are done in BUSD (BEP-20).

Smart Contracts and Blockchain

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)
  • 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 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
