Though only the proxy contracts are listed as in-scope, current implementation and any further updates to the implementation contracts are considered in scope. When reporting a bug, please make sure to select the relevant proxy smart contract as the target.

However, only those in the Assets in Scope table are considered as in-scope of the bug bounty program.

If an impact can be caused to any other asset managed by Metronome 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.

Metronome is continuing its journey by relaunching and innovating for DeFi in 2022. Metronome was a pioneer in the DeFi space when it was launched in June 2018. With an elegant system of four smart contracts, Metronome has had success with its daily auctions and DEX functionality. Since Metronome’s launch, DeFi has evolved due to the composable nature of protocols.

Metronome Smart Contracts

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. 

Bounty payouts will be dependent on actual risk to the platform.  Total bounty will either be the minimum of the range, or 5% of the total funds that could be lost in the exploit (up to the maximum cap based on the tier severity) - whichever amount is greater.

All smart contract and web/app 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. Bug reports are required to include a runnable PoC in order to prove impact. Exceptions may be made in cases where the vulnerability is objectively evident from simply mentioning the vulnerability and where it exists. However, the bug reporter may be required to provide a PoC at any point in time.

Known issues highlighted in the following audit reports are considered out of scope: 
- [https://github.com/autonomoussoftware/metronome-synth-audit/wiki/Audit](https://github.com/autonomoussoftware/metronome-synth-audit/wiki/Audit)

Payouts are handled by the __Metronome__ team directly and are denominated in USD. However, payouts are done in __USDC, DAI,__ and __MET__, at the discretion of the project.
