Pay with Crypto at 190+ Online Stores

0fiat is a free Chrome browser extension that enables cryptocurrency payments at major online stores. You can spend USDT or USDC at 190+ retailers including Amazon, Adidas, Nike, and eBay — without needing a crypto debit card, KYC verification, or paying any transaction fees.

0fiat currently supports USDT (Tether) and USDC (USD Coin) — both US dollar-pegged stablecoins. Payments can be sent across multiple blockchain networks including ERC-20 (Ethereum), BEP-20 (BNB Chain), and SPL (Solana). Support for additional cryptocurrencies and networks is planned in future updates.

0fiat works across 190+ online stores spanning multiple countries and categories — including fashion brands like Nike and Adidas, marketplaces like Amazon and eBay, electronics, travel, and more. New stores are added regularly. View the full list of supported stores.

Your funds remain fully under your control at all times.
