Ensuring protocol security with Immunefi bug bounty program
Maple Finance is an institutional capital marketplace powered by blockchain technology. Developed to solve the inefficiencies seen in traditional systems, Maple brings the corporate credit market 100% on-chain using smart contracts to remove time and cost frictions, and blockchains for immutability. Today the Maple platform has found product-market fit amongst crypto-native institutions needing access to capital to power their business operations.
We’re committed to ensuring the safety of our platform for all users including Borrowers, Lenders, Pool Delegates and Cover Providers. We recently earned an impressive 92% in a Process Quality Review from @DefiSafety indicating how closely our security, testing, auditing, validity processes and documentation follow best-practice: https://www.defisafety.com/pqrs/78.
Now, in partnership with Immunefi, Web3’s leading bug bounty platform protecting $100 billion in user funds, we’re kicking off a bug bounty program to prevent:
- Thefts and freezing of principal of any amount
- Thefts and freezing of unclaimed yield of any amount
- Thefts and freezing of any collateral
- Unintended changes in smart contract permissioning
- Unintended changes in proxy/upgradeability functionality
- Unfair liquidations of collateral
For more information on Immunefi, please visit their website at https://immunefi.com/.
The program opens at 12.30pm EST on 2/25/2022, and you can submit bugs here: https://immunefi.com/bounty/maple.
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.
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.
All known issues highlighted in the following audit reports are considered to be out-of-scope:
Maple requires KYC to be done for all bug bounty hunters submitting a report and wanting a reward. The information needed is a government issued photo ID as well as a proof of address issued within the last 3 months (eg. utility bill).
Payouts are handled by the Maple team directly and are denominated in USD. However, payouts are done in USDC or MPL.
Critical USD 50 000
High USD 25 000
Medium USD 1 000
Assets in Scope
All proxies deployed from the listed factories are also considered as in-scope.
