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 app bug reports must come with a PoC in order to be considered for a reward. All Medium and Low app bug reports require a suggestion for a fix to be eligible for a reward. 

The following vulnerabilities are not eligible for a reward:

  - Any vulnerability that can only be abused by a local attacker
  - Local Attackers (with access to the user’s machine/browser) are not part of our threat model.

Bug reports involving the ability to correctly determine the seed phrase will be paid at __USD 150 000__. All other extension bugs that are critical and result in loss of funds are paid at __USD 50 000__. High, Medium, and Low Web/App bug reports have the final reward determined by the BlockWallet team depending on exploitability, final impact, and ease of attack  

Payouts are handled by the __BlockWallet__ team directly and are denominated in USD. However, payouts are done in __USDC__.
