# Bug Bounty

## Overview

Balancer has completed smart contract audits with Trail of Bits and Open Zeppelin. We also will run a continuous bug bounty program for the bronze release of Balancer core.

## Scope

The bug bounty covers any of the core smart contracts deployed on Mainnet. The code can be found at: <https://github.com/balancer-labs/balancer-core>

Submissions should be based off commit hash: <https://github.com/balancer-labs/balancer-core/tree/2d88257fb27ad3c84b5166304a342e66055a81b3>

Mainnet BFactory can be found at: <https://etherscan.io/address/0x9424b1412450d0f8fc2255faf6046b98213b76bd>

*Additional second layer contracts, such as the exchange proxy or individual smart pool contracts, may be added at a further date.*

## Rewards

The bounty program will pay out rewards according to the severity of a vulnerability. The final reward amount is at the sole discretion of Balancer Labs. See eligibility section below for more details.

## Reporting / Disclosures

Please report any findings to <security@balancer.finance>, with full details about any vulnerability and steps / code to reproduce. Allow us time to review and remediate any findings before public disclosure.

## Ineligible Findings

* Duplicate vulnerabilities. Only the first reporter will be rewarded.
* Findings already known as part of a formal audit.
* Findings related to non-standard ERC20 tokens might be ineligible as many vulnerabilities might be inserted in non-standard ERC20 tokens on purpose for applying for this bug bounty.&#x20;
