Crypto payments platform 0fiat has added Polygon support, expanding its stablecoin checkout option to one of the cheapest and fastest networks for everyday spending.
Crypto payments platform 0fiat has integrated the Polygon network on its platform, allowing users to spend USDC and USDT directly at more than 190 online stores. The company announced the rollout yesterday on its official X account, and the news was quickly amplified by Polygon itself.
With the new integration, anyone using 0fiat can now check out on supported merchants including major names like Amazon, Flipkart, Nordstrom, and Sephora, using stablecoins on Polygon, alongside the platform’s existing support for Ethereum, BNB Chain, Tron and Solana. Polygon is widely regarded as one of the most affordable and fastest networks for stablecoin transfers, which makes it a natural fit for a checkout product designed to feel as smooth as a regular card payment.
In its announcement post on X (formerly Twitter), 0fiat said the integration is part of its broader push to make crypto spending genuinely usable in day-to-day life. Instead of forcing users to top up a card or go through identity verification, 0fiat works as a browser extension that connects directly to a self-custody wallet such as MetaMask, Phantom or Trust Wallet. Shoppers approve the transaction, and the merchant receives local currency on their end, key benefits of the 0fiat is that they take no KYC, no card issuance, no monthly fees.
The announcement got an unusually warm reception from the Polygon side. Polygon’s official handle quoted the news on X, and the post was retweeted by Marc Boiron, CEO of Polygon Labs, and Sandeep Nailwal, Polygon co-founder and CEO of the Polygon Foundation. That kind of public endorsement from the top of Polygon’s leadership is a strong signal that the network sees consumer-facing payment apps like 0fiat as central to its strategy. Polygon has spent the last year leaning hard into payments and real-world assets, with Nailwal repeatedly emphasising stablecoins and everyday transactions as the chain’s main thesis going forward.
A Real Alternative to Crypto Cards
0fiat has positioned itself as a crypto cards alternative rather than a competitor to existing wallets or exchanges. The pitch is straightforward: most crypto debit cards require KYC, charge issuance and maintenance fees, and need users to pre-load funds. 0fiat skips all of that. Funds stay in the user’s wallet until checkout, settlement happens on regular fiat rails on the merchant side, and the service itself is free to install and use.
Adding Polygon strengthens that pitch considerably. Network fees on Polygon are typically a few cents at most, which makes small everyday purchases like a coffee, a takeaway order, an Amazon orders, economically viable in a way that high-fee networks struggle with. For users in markets where 0fiat is already live across 45+ countries, the Polygon option means lower friction and a meaningfully cheaper checkout experience.
Mobile App Now Live
The Polygon news lands shortly after 0fiat launched its mobile app, a long-requested feature from the user base. Until recently, the platform was extension-only, available on Chrome and Chromium-based browsers like Edge and Brave. Reviews on the Chrome Web Store and Trustpilot frequently asked for an on-the-go option, and the team has now delivered one, making it possible to use the service for travel bookings, food orders and shopping without needing a desktop browser.
Taken together, the Polygon integration and the mobile launch mark a noticeable step up for the platform. 0fiat is no longer just a niche browser tool for crypto-native shoppers; it is starting to look like a credible everyday checkout option for the growing pool of stablecoin holders who want to spend, not just trade.
What It Means for Users
For shoppers, the practical takeaway is simple. Anyone with USDC or USDT sitting in a self-custody wallet can now use it to pay with crypto at a long list of mainstream stores, using Polygon’s low fees rather than paying Ethereum gas. There is no card to apply for, no identity check, and no waiting period. Install the extension or the app, connect a wallet, and check out.
As stablecoin adoption continues to climb and Polygon doubles down on its payments roadmap, integrations like this one are likely to define the next wave of crypto checkout. 0fiat appears to be moving early and quickly to claim that ground.
