Sovryn 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.

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. Explanations and statements are not accepted as PoC and code is required. In addition, Critical and High severity reports must come with a suggestion for a fix to be considered for a reward. 

Critical and High severity Solidity Contracts 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 or pseudo code is required. In addition, Critical and High severity reports must come with a suggestion for a fix to be considered for a reward.

Rewards for critical smart contract and blockchain/DLT vulnerabilities are further capped at 10% of economic damage, with the main consideration being the funds affected in addition to PR and brand considerations, at the discretion of the team. However, there is a minimum reward of __USD 50 000__ for Critical bug reports. 

For Blockchain/DLT infrastructure, only vulnerabilities that result in direct economic damage to yield will be considered as __High__, and only vulnerabilities that result in direct economic damage to principal funds will be considered as __Critical__.

Payouts are handled by the __Sovryn__ team directly and are denominated in USD. 50% of the payouts are done in __BTC__, and the other 50% is paid out in __SOV__ according to a 24 month vesting schedule (with monthly vesting).

| __Blockchain/DLT__     | __Payout__     |
| ---------- | ---------- |
| __Critical__       | Up to USD $1,000,000       |
| __High__       | USD $22,140       |
