0fiat is completely free to use. There are zero issuance fees, zero transaction fees, and zero maintenance fees. You pay only the crypto equivalent of your purchase amount — no hidden charges, no subscription, and no markup on the exchange rate.

The official 0fiat extension is available on the Google Chrome Web Store — it's free to install with no account required. You can also click here to install it directly. It works on Chrome and all Chromium-based browsers including Edge and Brave.

No, 0fiat does not currently have a token. We are focused on building a reliable crypto payments product. Any future token plans will be announced officially through our social channels.

• 0fiat is non-custodial — your crypto stays in your wallet until you approve the payment

Yes, certain merchants restrict spending via crypto. Spend caps vary by store and are set by the merchant, not by 0fiat. You can find the detailed list of spend caps for each supported merchant inside the 0fiat dashboard after installing the extension.
