Program Overview

Moola is a non-custodial liquidity protocol built on the Celo blockchain that is democratizing access to yield and credit. Depositors actively earn yield which is paid for by borrowers who are able to take over-collateralized loans in perpetuity, under-collateralized credit delegated or flash loans. Moola has shared ancestry with Aave v2.

For more information about Moola, please visit https://moola.market/.

This bug bounty program is focused on their smart contracts, website and app and is focused on preventing:

  • Thefts and freezing of principal of any amount
  • Thefts and freezing of unclaimed yield of any amount
  • Website goes down
  • Leak of user data
  • Deletion of user data
  • Access to sensitive pages without authorization

Rewards by Threat Level

Rewards are distributed according to the impact of the vulnerability based on the 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 bug reports must come with a PoC with an end-effect impacting an asset-in-scope in order to be considered for a reward.

Moola requires KYC to be done for all bug bounty hunters submitting a report and wanting a reward. Bug bounty hunters will need to show a government-issued ID, including a physical address.

Payouts are handled by the Moola team directly and are denominated in USD. However, payouts are done in cUSD or MOO at the discretion of the team. For payouts done in MOO, the price of MOO will be calculated based on a 30-day average USD price. MOO payments may incur a linear unlock period up to twelve months.
