How stablecoin payments work: issuers, chains, settlement

A stablecoin payment is a transfer of a token designed to hold a steady value against a currency, such as Circle's USDC (US dollar) or EURC (euro), from the payer's crypto wallet to an address controlled by the merchant or its payment provider, with the transfer recorded on a public blockchain. The merchant can keep the tokens, or a provider can convert them and pay out ordinary currency, while the issuer stands behind each token with reserves and redeems it for cash.

The technology sits on three layers: the issuer that creates and redeems the token, the blockchain that records who holds it, and the payment providers that connect wallets, merchants and banks. The table below maps them.

How a stablecoin checkout payment works, step by step

Stripe's published flow is a useful reference because it shows a card-style checkout with a crypto rail underneath.

1. The shopper picks crypto at checkout. The option appears among the other payment methods.
2. The shopper is redirected. Stripe sends the shopper to its own crypto payment page, where they choose a stablecoin and a network and connect their wallet.
3. The wallet signs a transfer. The shopper approves the payment in their wallet, which broadcasts it to the chosen blockchain.
4. The transfer is confirmed on-chain. Once the network records it, the shopper sees a confirmation and can be sent back to the merchant's site.
5. The provider converts. Stripe says completed payments settle in the merchant's Stripe balance in the merchant's local currency.
6. The merchant is paid out. Funds move to the merchant's bank account on the provider's payout schedule, which Stripe says varies by network.

Refunds run the other way. Stripe states that refunds always go back as stablecoins to the customer's original wallet.

Issuers and reserves

The issuer is what makes a stablecoin "stable". It accepts money, creates tokens, and promises to swap them back.

Redemption is not open to everyone directly. Circle says its Circle Mint service lets exchanges, institutional traders, banks and large financial firms mint and redeem USDC with Circle, and that startups and small businesses go through on- and off-ramp providers in its Alliance Program. Individuals usually get USDC through exchanges, neobanks and wallets. Our Circle profile covers the company in more detail.

Chains

A stablecoin can exist natively on several blockchains at once. Circle's developer documentation lists USDC on 38 chains, including Ethereum, Solana, Base, Arbitrum, Polygon PoS, Stellar, Avalanche C-Chain and its own Arc, and EURC on nine, including Ethereum, Solana, Base and Stellar.

The chain matters for payments because a token on one network cannot simply be sent to an address on another. Circle warns that sending unsupported tokens, including bridged USDC, to a Circle Mint address can mean a loss of funds. Merchants and their providers therefore support a fixed list of token and chain pairs.

On-ramps and off-ramps

An on-ramp turns bank money into stablecoins; an off-ramp does the reverse. For a merchant, the off-ramp is usually built into the payment provider: Stripe converts to local currency before settlement. For a business holding tokens itself, the off-ramp is an exchange, a ramp provider or, at institutional scale, the issuer directly. Stripe also offers a fiat-to-crypto on-ramp product for businesses that want to let users buy crypto. Exchanges are covered in our Coinbase profile.

Merchant settlement

There are two quite different uses of stablecoins in merchant payments.

Shopper pays in stablecoins. The shopper sends tokens, and the provider settles the merchant in fiat. Stripe's published terms for this, as of 3 November 2026:

Card network settles in stablecoins. Here the shopper still pays by card, and stablecoins are used between the institutions behind the scenes.

MiCA basics

In the EU, stablecoins fall under the Markets in Crypto-Assets Regulation, Regulation (EU) 2023/1114, which ESMA says applied in full from December 2024. MiCA splits stablecoins into two kinds. E-money tokens (EMTs) reference one official currency, such as the euro or the dollar; holders can redeem them from the issuer at face value, and they pay no interest. Asset-referenced tokens (ARTs) reference other assets or a basket. According to the European supervisors' joint factsheet, only credit institutions and e-money institutions may offer EMTs to the public in the EU. Issuers and service providers can be checked in ESMA's interim MiCA register, last updated on 30 October 2026 according to ESMA's MiCA page. Our MiCA explainer covers licensing and dates in full.

Benefits and trade-offs for merchants

The European supervisors' factsheet also warns that stablecoins may not hold their value in stressed markets. More guides sit in the crypto hub and the cross-border hub.
