Rewards by Threat Level

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2.1. 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.

Issues previously highlighted in the following audit reports are considered as out of scope:

In addition, the following bug are also considered out of scope:

  • The team is aware that UniswapV3 TWAP oracles can be manipulable if liquidity is low and there is a warning for low liquidity pairs on the front-end to address this. Hence, security assessments should be done under the assumption that oracles return the correct price.
  • Tokens ERC20 with more than 36 decimals, that are deflationary or perform some kind of rebasing.
  • Bug reports that require escalated privileges

Payouts are handled by the Mean Finance team directly and are denominated in USD. However, payouts are done in USDC.
