0Fiat is a browser extension that lets crypto holders spend their stablecoins at over 150+ online stores with no banks, no crypto cards and without KYC verification required. Users simply install the extension, shop at any supported online brand from the available list and pay directly from their self-custodial wallet (using USDT/USDC/PYUSD across multiple networks like Solana, BNB, Ethereum) at checkout in just a few clicks.

The core problem 0Fiat solves is the friction gap between owning crypto and actually using it. Traditional crypto spending solutions force users through identity verification, geographic restrictions, and opaque fees that break the promise of instant, borderless spending. 0Fiat eliminates all of that by connecting wallets directly to merchants, without added fees, no identity dossiers, and no middlemen standing in the way.

Merchants receive a seamless purchase experience on the back end while users enjoy a native crypto transaction from start to finish. Key features include multi-wallet support, discounts of up to 14% at supported online stores, and a referral and cashback rewards program that lets early users share in the network's growth. The platform is actively expanding its global store network and tracking new country rollouts in real time, with the long-term vision of making any wallet usable for everyday spending anywhere in the world.

In short, 0Fiat is the checkout layer that makes spending crypto feel as easy and intuitive as using a credit card, without surrendering self-custody, privacy, or control.
