Rewards by Threat Level

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

The following vulnerabilities are not eligible for a reward:

  • Storing a box in a box prevent to withdraw tokens unless it’s sent back to a regular address
  • Storing a box in a box and vice-versa prevent for ever to withdraw tokens
  • Admin can specify a token id range for a type that overlap the range of another type
  • We consider the collision hash impossible
