0fiat

0Fiat is a checkout agent that lets you pay with stablecoins (USDT/USDC) at almost any online store - even if the store doesn’t accept crypto & at a discount.

It connects your wallet directly to the checkout, so there’s no need to convert to fiat or load a crypto card, and no extra payment fees.

Just install the browser extension:
1. Shop on your favourite store and go to checkout
2. Click “Pay with Crypto” and select your wallet + stablecoin
3. Approve the transaction

The merchant receives local currency without you going through the hassle of off-ramping.
