How to off-ramp USDC to an IBAN

To move USDC to an IBAN, send it on a network your provider supports, convert it to EUR or USD, and pay the money out by SEPA or wire. With Holyheld Business, you receive the USDC, convert it and send the SEPA or wire payment from the same account.

Best for

• A company paid in USDC that settles its costs in EUR by SEPA.
• Moving a stablecoin balance into USD to pay a supplier by wire.
• A finance team that needs the transaction hash and the bank reference on one record.

Before you start

1. The asset and network. For example, USDC on Base. Both must be supported for your transaction.
2. The wallet you send from. A self-custody wallet or an account at an exchange.
3. The destination account. The IBAN, the account holder's name and the currency it receives.
4. The reference. The invoice number or purpose the transfer settles.

Check the asset and the network together

Circle issues USDC natively on many networks and publishes the official contract address for each, including Ethereum, Arbitrum, Base and Solana (Circle). Circle also distinguishes native USDC from bridged USDC: a service that accepts one does not automatically accept the other.

Holyheld works with USDC on Ethereum, Arbitrum, Optimism, Base, Polygon and Solana, and with EURC on Ethereum, Base and Solana. Use the receiving instructions in your account, and confirm the asset and network combination before sending.

Send the USDC

Copy the receiving address from your account and paste it into your wallet. Never retype it, and never copy it from your transaction history, where attackers plant look-alike addresses. Researchers counted 270 million of these address-poisoning attempts against 17 million victims, with at least $83.8 million lost (USENIX Security 2025).

For a first payment from a new wallet, send a small test amount before the full one. Keep the transaction hash: it is the onchain reference for the payment.

Convert to EUR or USD

Once the USDC arrives, review the quote: the asset, the amount, the fiat amount you will receive and the fees.

If you hold a different stablecoin than the one your route needs, swap it first.

Pay out to the IBAN

Send EUR to an IBAN by SEPA. For USD, send an international wire (SWIFT) to the IBAN: it arrives in 1–3 business days, and banks along the way may deduct their fees from the amount received.

The blockchain confirmation and the bank credit are separate events. A fast onchain transfer does not set the bank arrival time, so check the route before committing to a deadline. To check an IBAN's format before you pay, use the free IBAN calculator.

What it costs

The EUR or USD amount you receive depends on the conversion quote at the time.

When this route doesn't fit

• The asset or network isn't supported for your transaction. Swap it, or move it to a supported combination, before you send.
• The money must arrive on a set day. Onchain speed doesn't set the bank arrival time; discuss the payment with your concierge first.
• The supplier wants stablecoins. Pay them directly instead: read How to pay suppliers in stablecoins.

Common questions

What happens if I send USDC on the wrong network?

Funds sent on a network the receiving instructions don't name may not arrive. Contact your concierge with the transaction hash.

Can I send from an exchange account instead of my own wallet?

Yes, as long as the exchange sends the asset on the network named in your receiving instructions.
