Emergency actions: pause everything, freeze one address, switch off a stablecoin that has lost its peg	Immediate	Pauser wallet

Worked example: a redemption window

Mint

A business mints 1,000,000 USDh. Its wallet now holds 1,000,000 USDh, so its limit is set to 500,000 USDh per window.

Monday

It redeems 300,000 USDh. A 7-day window opens.

Wednesday

It asks to redeem another 300,000 USDh. That would take it to 600,000 in this window, over the limit, so the contract refuses. It can still redeem 200,000.

The next Monday

The window closes. A new one opens with its next redemption.

These figures show how the rule works. They are not a forecast.

Where this page differs from the Mint user agreement or the USDh terms, those documents win.
