88mph · interactive mechanism simulation

Depositors lock a fixed rate on a stablecoin deposit; a "Yield Token" funder pays upfront to take the other side of the bet on the underlying variable-rate venue. At maturity the actual yield is split: depositors always get principal + the fixed promise, funders keep whatever's left over — or eat the shortfall.

Illustrative simulation. Defaults mirror 88mph's researched mechanism: a quoted fixed rate (EMA of variable yield minus a safety margin), Yield Token funders taking the other side of the rate bet, MPH liquidity-mining rewards, and the Nov 2020 launch-day MPH-minting exploit that was rescued with no user losses. Deposit sizes, timing and the exact exploit numbers are simplified for visualization — not live onchain data. Part of The Onchain Experiment Atlas.
