Rewards are distributed according to the impact the vulnerability could otherwise cause based on the Impacts in Scope table further below. 

__Overtime Attack Limitations__

In cases of attacks executed over time for smart contract and blockchain/DLT bugs, an explicit two hour window without human intervention is provided, starting from the first erroneous or malicious action. Only achievements during this window will be counted, regardless of further impact.

__Public Disclosure of Known Issues__

Bug reports covering previously-discovered bugs acknowledged below are not eligible for any reward through the bug bounty program.

__Proof of Concept (PoC) Requirements__

A PoC is required for the following severity levels:
- Blockchain/DLT - Critical

In addition, PoC will be required for the following low impact:
- Undocumented panic

All PoCs submitted must comply with the Immunefi-wide [PoC Guidelines and Rules.](https://immunefisupport.zendesk.com/hc/en-us/articles/9946217628561-Proof-of-Concept-PoC-Guidelines-and-Rules) Bug report submissions without a PoC when a PoC is required will not be provided with a reward.
