OPEN LAB · PEG / RESERVE / REDEMPTION

Stablecoin Free Lab

Deposit collateral, mint USD-LAB, move the market price, redeem, and apply reserve losses. Watch where “stability” fails at the boundary. Every number is virtual.

STABLECOIN 001 · PEG / RESERVE / REDEMPTION

COLLATERAL → USD-LAB

Put a one-dollar target stablecoin into a state machine and watch minting, price, redemption, and reserves define the stability boundary.

Supply is a protocol promise; reserves are the assets actually available at exit. Keep both on the same ledger.

PRICE INPUTS · PEG BOUNDARYTarget price is not market price

Move the outside market, then choose when the oracle updates. Current deviation 0.00%.

RESERVE RISK · RUN SCENARIOWho reaches the boundary after reserve loss?

Supply does not shrink automatically when reserves are lost. Apply loss, redeem part of the balance, and inspect coverage and exit capacity.

Not sure where to start? Try these four experiments.

01

Deposit 100 COLLATERAL, mint 60 USD-LAB, and record the minimum ratio and remaining issuance room.

02

Move the market price to $0.94, redeem, and follow supply and reserves shrinking together.

03

Drop the market price while keeping the old oracle, then update it and compare when the protocol sees the move.

04

Apply a reserve loss, redeem repeatedly, and observe when coverage crosses the safety boundary.
