CRYPTO ON-RAMP

Fiat-to-crypto payments

Give customers a way to pay without owning crypto first. Connect your own Coinflow account and receive USDC on Base in your invoice wallet.

Set up card payments

Customer chooses card
Coinflow handles checkout
Your wallet receives USDC

A crypto on-ramp, also written onramp, turns fiat money into crypto. Wholly Crypto connects that payment to your invoice and verifies the funds on-chain.

Card payments → USDC on Base

Own provider account. Enable card payments per store.

Optional per store. Currently USDC on Base only; card payments do not cover all 30 networks.

Availability, identity checks, limits and provider fees depend on your Coinflow account and the customer’s location. Review the final price on Coinflow before paying.

Read the setup requirements

Coinflow is the first supported provider. This list will expand as more integrations become available.

Paid means received

An invoice settles only after its USDC arrives and meets your blockchain confirmation policy. A card authorization or return to checkout is not proof of payment.

On-ramp or exchange sweep?

An on-ramp takes a customer’s fiat payment into crypto. Exchange sweeps send crypto you already received to Kraken, Binance or Coinbase for conversion into fiat or another asset.

Frequently asked questions

Does card payment need identity checks?

Coinflow may require verification. Direct wallet-to-wallet payments remain a separate option without a Wholly Crypto customer account or Wholly Crypto identity check.

Which fees apply?

Wholly Crypto’s processing fee still applies. Coinflow fees and currency conversion are separate and shown before payment. Later wallet transfers also need network fees.
