Clear answers.

The essentials of accepting stablecoin payments with 0fiat.

Have another question?
What is a stablecoin payment gateway?

A stablecoin payment gateway connects a business’s payment flow with customers paying in stablecoins. With 0fiat, your business integrates payment acceptance and arranges how it receives settlement during onboarding.

Can I accept USDT and USDC payments?

USDT and USDC are the focus of 0fiat’s stablecoin payment offering. The team will confirm the payment options available for your business during onboarding, before you present them to customers.

How does my business receive settlement?

Your business receives settlement in stablecoins to a merchant wallet. Confirm the supported settlement assets, wallet setup, fees and timing with 0fiat before going live.

How long does settlement take?

Payment confirmation and settlement are separate stages. Timing depends on the agreed settlement method and applicable processing requirements. The team will confirm the schedule for your business and when settled funds become available in your wallet.

How do I integrate the payment API?

Request API access and share your business model and payment flow. The 0fiat team will confirm integration requirements, provide the applicable documentation and credentials, and help you scope payment confirmation and settlement before launch.

What are the payment gateway fees?

Contact 0fiat for the commercial terms that apply to your business. Discuss payment processing and settlement costs together so you understand the full cost of your chosen setup.

What should I know about onboarding and refunds?

Verification requirements and refund handling should be agreed during onboarding. Describe your operating markets and customer support process when requesting access so the team can clarify what applies to your integration.

Is this the same as the 0fiat gift-card API?

They serve different purposes. The payment gateway is for collecting customer payments for your own products or services. The B2B Gift Card API adds a gift-card catalog and ordering flow to your product.
