All smart contracts of Balancer can be found at [https://github.com/balancer-labs/balancer-v2-monorepo](https://github.com/balancer-labs/balancer-v2-monorepo). However, only those in the Assets in Scope table are considered as in-scope of the bug bounty program.

If a Critical impact can be caused to any other asset managed by Balancer that isn’t on this table but for which the impact is in the Impacts in Scope section below, you are encouraged to submit it for the consideration by the project.

Balancer is a community-driven protocol, liquidity provider, and price sensor that empowers decentralized exchange and the automated portfolio management of tokens on the Ethereum blockchain and other EVM compatible systems.

Rewards are distributed according to the impact of the vulnerability based on the [Immunefi Vulnerability Severity Classification System V2.2](https://immunefi.com/immunefi-vulnerability-severity-classification-system-v2-2). This is a simplified 5-level scale, with separate scales for websites/apps, smart contracts, and blockchains/DLTs, focusing on the impact of the vulnerability reported.

All Critical/High severity bug reports must come with a PoC with an end-effect impacting an asset-in-scope in order to be considered for a reward. Explanations and statements are not accepted as PoC and code is required.

Critical smart contract vulnerabilities are further capped at __10%__ of economic damage, taking into account the funds at risk at the moment of the bug report submission. However, there is a minimum reward of __USD 250 000__. Additionally, the maximum reward is capped at __USD 1 000 000__, even if __10%__ of the damage in USD equivalent is greater than __USD 1 000 000__.

High severity smart contract vulnerabilities are also further capped at __10%__ of economic damage, taking into account the funds at risk at the moment of the bug report submission. However, there is a minimum reward of __50 000 USD__. Additionally, the maximum reward is capped at __USD 250 000__, even if __10%__ of the damage is greater than __USD 250 000__.

Vulnerabilities involving non-standard ERC20 tokens are considered out of scope, as it would be trivial to insert an exploit into a token for the sake of applying to this bug bounty. A standard, Balancer-compatible ERC20 token is one that conforms to all [EIP-20 interfaces](https://eips.ethereum.org/EIPS/eip-20) and exhibits expected behavior in implementation; i.e., transfers move exactly N tokens from sender to recipient, and balances do not change by any means other than transfers. Notably, tokens with transfer fees, rebasing supplies, streaming mechanics or multiple entrypoints are not compatible with Balancer, but that list is not exhaustive.

Known issues such as those previously highlighted in the following audit report are considered out of scope (list is not exhaustive): 
  - [https://github.com/balancer-labs/balancer-v2-monorepo/tree/master/audits](https://github.com/balancer-labs/balancer-v2-monorepo/tree/master/audits) 

Payouts are handled by the __Balancer__ team directly and are denominated in __USD__. However, payouts are done in __ETH__ or __USDC__, at the discretion of the team.
