Announcing 0% conversion: USDC to USD and EURC to EUR

Converting USDC to USD and EURC to EUR inside a Stablerail business account now has a 0% conversion fee, with no spread applied. Receiving fiat is also free, and same-currency fiat payments are free over ACH, SEPA, SEPA Instant and UK Faster Payments. Cross-currency payments remain subject to the rate for your plan.

What changed

The pricing change removes the cost of a common stablecoin treasury step: moving from a digital currency balance into the corresponding bank currency before making a payment.

The 0% rate applies to the specific conversion directions announced here: USDC to USD and EURC to EUR. It means there is no conversion fee and no spread added to those conversions. It does not mean that every possible transaction, blockchain transfer or foreign-exchange payment is free.

Plan subscriptions, volume limits and signer counts are unchanged. Existing customers do not need to enable a new setting; the updated pricing is reflected on their next applicable payment.

Why 0% conversion matters for stablecoin treasury

A supplier payment funded with stablecoins can contain several economically distinct steps. The business may receive a stablecoin, transfer it into a treasury wallet, convert it into bank money and then send a domestic or regional fiat payment. If each step has its own fee or spread, the total cost can be difficult to identify before the payment is approved.

Removing the fee and spread from the paired conversion makes the cost model easier to explain. If a company holds USDC and needs to pay a US supplier in USD, the USDC-to-USD conversion does not create an additional percentage charge. If it holds EURC and needs to pay a supplier in EUR, the same principle applies.

A cross-currency payment is different. For example, funding a EUR supplier payment from a USD balance changes the currency of the funds, so the plan's cross-currency rate applies. The pricing distinction is therefore based on whether the payment stays within the matching currency or requires foreign exchange.

The practical rule: converting USDC to USD or EURC to EUR has no conversion fee or spread. A fee applies when the payment itself changes currency.

How common payment scenarios are priced

These examples describe the account-level conversion and payment charges. A blockchain network fee may still arise when stablecoins are transferred onchain, and another underlying rail charge may apply where the rail itself imposes one. Payment timing can also vary by rail, banking cut-off, destination and counterparty bank; the 0% rate is a pricing change, not a promise that all rails settle at the same speed.

How a USDC-funded supplier payment works

A typical USDC-to-USD supplier payment can be handled as one controlled workflow:

1. Receive USDC from a customer or another approved source into the self-custodied treasury wallet.
2. Select the amount of USDC that needs to be converted into USD.
3. Review the conversion before confirming it. The conversion fee is 0%, and no spread is added.
4. Create the supplier payment, select or verify the counterparty and attach the invoice or other supporting document.
5. Complete sanctions and address screening before the payment is sent.
6. Collect the approvals and signatures required by the company's signing quorum.
7. Send the USD payment by ACH and retain the receipt, screening result and approval trail with the payment record.

The equivalent EUR workflow converts EURC into EUR and sends the resulting funds over SEPA or SEPA Instant where supported. Keeping the conversion, approval and payout evidence together reduces the work required to reconstruct why a payment was made and who authorised it.

What 0% does and does not include

There is no conversion fee or spread on USDC-to-USD and EURC-to-EUR conversions. The same-currency payout is also free when it uses one of the listed supported rails.

Cross-currency payments are not included. If the destination currency differs from the fiat balance used to fund the payment, the applicable plan rate is 0.79%, 0.49% or 0.29%, with custom pricing available on Enterprise.

Network and third-party rail charges are separate. Moving a stablecoin onchain may require a network fee. A fee imposed directly by an underlying payment rail may also remain payable where applicable.

Custody treatment does not change. Digital assets remain self-custodied. Fiat balances are held with banking partners and are not self-custodied. Treasury teams should reflect that distinction in wallet controls, account mappings and internal custody documentation.

Accounting events still need to be recorded. A zero-fee conversion may simplify reconciliation, but it does not remove the need to record the stablecoin disposal or conversion, the resulting fiat balance and the later supplier payment. The appropriate accounting and tax treatment depends on the company's policies and jurisdiction.

A finance checklist before the first payment

• Confirm the currency pair: check that the transaction is USDC to USD or EURC to EUR.
• Separate conversion from foreign exchange: identify whether the supplier will receive the same fiat currency or whether a cross-currency fee applies.
• Review the full route: include any onchain transfer and underlying rail charges, not only the account conversion fee.
• Verify the beneficiary: confirm bank details, legal name and invoice information before approval.
• Apply the signing quorum: require the correct approvers rather than relying on a single operator.
• Retain evidence: export the conversion record, screening result, approvals, supporting documents and payout receipt for reconciliation and audit.
• Map the ledger entries: reconcile the wallet debit, fiat credit and supplier-payment debit as separate events.

Controls and audit evidence remain essential

Lower pricing should not reduce payment controls. Stablecoin-funded payouts still need clear separation between preparation, approval and signing. Finance teams should also be able to show the source balance, beneficiary, invoice, screening outcome, approval history and final payment receipt.

Stablerail combines stablecoin treasury, approvals and signing quorum, pre-send sanctions and address screening, global payouts, fiat off-ramp, corporate cards and exportable audit evidence in one business account. The pricing change affects the conversion and same-currency payment costs described above; it does not alter the underlying approval, custody or evidence requirements.

Getting started

Existing customers receive the new pricing automatically on their next applicable payment, with nothing to switch on. Before sending a payment, review the quoted route and currency to confirm whether it is a free paired conversion and same-currency payout or a cross-currency transaction charged at the account's plan rate.
