Interlay 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, smart contracts, and blockchains/DLTs, focusing on the impact of the vulnerability reported.

All 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. All Smart Contracts and Blockchain/DLT bug reports require a PoC to be eligible for a reward. Explanations and statements are not accepted as PoC and code is required.

Critical, high, and medium smart contract and blockchain/DLT vulnerabilities are capped at 10% of economic damage, primarily taking into consideration funds at risk, but also PR and branding aspects, at the discretion of the team.  However, there is a minimum Critical reward of USD 5 000, minimum High reward of USD 1500, and minimum Medium reward of USD 750. 

The following vulnerabilities are not eligible for a reward:
