The bug bounty program covers its Website and Chrome Extension and is focused on preventing the following impacts:

  • Thefts and freezing of principal of any amount
  • Theft of any funds / tokens / nfts
  • Leak of seed phrase
  • Manipulating the user to send funds within the wallet
  • Man in the middle attacks that lead to financial loss
  • XSS/CSRF with financial loss as a result
  • Loss of any fiat amount when user will be using on/off ramp services

Rewards by Threat Level

Rewards are distributed for critical vulnerabilities only, defined as vulnerabilities that lead directly to a financial loss for users.

All bug reports must come with a PoC demonstrating direct financial impact in order to be accepted.

Bug reports that do not contain a vulnerability that leads to a direct loss of funds are not accepted in this bug bounty program. Additionally, any vulnerability that involves social engineering is not in-scope.

Payouts are handled by the GeroWallet team directly and are denominated in USD. Payouts are done in $GERO.
