USDD · interactive mechanism simulation

USDD 2.0: users lock collateral in CDP vaults to mint USDD; undercollateralized vaults get liquidated; a PSM swaps 1:1 against USDT to defend the peg; sUSDD pays a savings yield. Edit the parameters, or test a TRX price crash.

Illustrative simulation. Reflects USDD 2.0's researched CDP + PSM design (vaults lock TRX/BTC/USDT, mint USDD, liquidate below the min collateral ratio; a PSM arbitrages 1:1 against USDT; sUSDD pays a savings yield) with starting values approximating reported figures (~112% average system collateralization). Amounts, timing and the crash response are randomized/compressed for visualization — not live onchain data. USDD v1 (2022) was an algorithmic design that depegged in a TRX selloff; the crash button lets you see how the v2 CDP + PSM system responds instead. Part of The Onchain Experiment Atlas.
