Moonbeam is an Ethereum-compatible smart contract platform on the Polkadot network that makes it easy to build natively interoperable applications. This Ethereum compatibility allows developers to deploy existing Solidity smart contracts and DApp frontends to Moonbeam with minimal changes. As a parachain on the Polkadot network, Moonbeam benefits from the shared security of the Polkadot relay chain and integrations with other chains that are connected to Polkadot.

Moonbeam Network Codebase

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 and smart contracts/blockchains, encompassing everything from consequence of exploitation to privilege required to likelihood of a successful exploit.

All  bug reports must come with a detailed PoC demonstrating the exploit in a real-world scenario; and written instructions to reproduce, in order to be considered for a reward. Theoretical vulnerabilities without a working POC will not be accepted. 
The payout for **critical vulnerabilities** is dependent on the ratio between the funds at risk and the **combined market cap** (as listed on coinmarketcap on the day of the report) of the Moonbeam and Moonriver Blockchains. 

The payout for __critical vulnerabilities__ is dependent on the ratio between the funds at risk and the combined __market cap__ (as listed on coinmarketcap on the day of the report) of the Moonbeam and Moonriver Blockchains. 

This ratio is known as the __“risk ratio”__, i.e.:

Risk Ratio = Funds at Risk / ( Moonbeam Market Cap + Moonriver Market Cap)

The exact payout is determined as follows:

  - If the risk ratio is at or below 0.5, the payout is calculated linearly between 2,500$ and 25K.
  - If the risk ratio is above 0.5, the payout is calculated linearly between $25K and $100K; with a maximum cap of $100K

This results in the following payout graph:

Note that a bug reported for one of either the Moonbeam or Moonriver networks that applies to both will be treated as a single report and paid only once. 

The Moonbeam Foundation requires KYC to be done for all bug bounty hunters submitting a report and wanting a reward. The information needed is an ID scan along with a selfie to verify identity. 

Payouts are handled by the __Moonbeam Foundation__ team directly and are denominated in USD. However, payouts are done in __USDT__ or __USDC__.

The Moonriver parachain on Kusama and the Moonbeam parachain on Polkadot (estimated launch in Jan 2022) are both included in the assets-in-scope.
