Program Overview

88mph is a DeFi protocol that allows users to lend crypto assets at a fixed interest rate or buy floating-rate bonds. With 88mph, users can earn upfront $MPH and staking rewards (100% protocol's revenues, DAI cash flow).

88mph is interested in securing its smart contracts and is primarily interested in preventing the loss of user funds, permanent impairment of the protocol state, or severe damage to the protocol state, in addition to any issue that might cause user dissatisfaction or minimal failure.

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.

Payouts are handled by 88mph directly and are denominated in USD. However, payouts are done in MPH.

Out of Scope & Rules

The following vulnerabilities are excluded from the rewards for this bug bounty program:

  • Attacks that the reporter has already exploited themselves, leading to damage
  • Attacks that rely on social engineering
  • Attacks requiring access to leaked keys/credentials
  • Attacks that rely on spamming
  • Attacks that rely on Denial of Service
  • Any physical attacks against 88mph property or data centers
  • Incorrect data supplied by third party oracles
    • Not to exclude oracle manipulation/flash loan attacks
  • Basic economic governance attacks (e.g. 51% attack)
  • Lack of liquidity
  • Best practice critiques
  • Sybil attacks

The following activities are prohibited by bug bounty program:

  • Any testing with mainnet or public testnet contracts; all testing should be done on private testnets
  • Any testing with pricing oracles or third party smart contracts
  • Attempting phishing or other social engineering attacks against our employees and/or customers
  • Any testing with third party systems and applications (e.g. browser extensions) as well as websites (e.g. SSO providers, advertising networks)
  • Any denial of service attacks
  • Automated testing of services that generates significant amounts of traffic
  • Disassembly or reverse engineering of binaries for which source code is not published, not including smart contract bytecode
  • Public disclosure of an unpatched vulnerability in an embargoed bounty
