88mphV3
Submit a BugProgram Overview
88mph is a DeFi protocol for providing fixed-term fixed-rate interest. It does so by pooling deposits with differing maturations and fixed-rates together and putting the funds in a yield-generating protocol, such as Compound, Aave, and yEarn, to earn floating-rate interest. The debt incurred by the promised fixed-rate interest of a deposit is offered as floating-rate bonds (or fundings as referred to in the contracts), which someone can purchase in exchange for the floating-rate interest generated by the corresponding deposit. Buyers of floating-rate bonds thus speculate on the floating-rate yield generated by the underlying protocol, while decreasing the debt of the pool and the risk of insolvency.
88mph is interested in securing its V3 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 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 Critical and High Smart Contract bug reports require a PoC and a suggestion for a fix to be eligible for a reward. Explanations and statements are not accepted as PoC and code is required.
Critical smart contract vulnerabilities are capped at 10% of economic damage, primarily taking into consideration funds at risk, but also PR and branding aspects, at the discretion of the team. However, there is a minimum reward of USD 10 000.
Payouts are handled by the 88mph team directly and are denominated in USD. However, payouts are done in MPH.
