Pay-by-Bank for Crypto: Open Banking Explained
The rail quietly replacing cards in parts of Europe. You approve the payment in your own banking app, it clears in seconds, and it fixes the decline problem cards cannot.

TL;DR
- Pay-by-bank pushes money straight from your account. You authorise it inside your own banking app rather than typing card details anywhere.
- It sits on open banking rules: PSD2 in Europe, the 2018 UK regime. PSD3 was politically agreed in November 2025 and is expected to apply around 2028.
- European instant payments became compulsory to receive from 9 January 2025, and to send in the eurozone from 9 October 2025, at up to 100,000 euros in ten seconds.
- Success rates beat cards, with TrueLayer reporting over 95%. The trade-off is that there is no chargeback, because you pushed the money yourself.
The card is fine and there is money in the account. The purchase fails anyway, and the bank sends a text asking whether it was really you, twenty minutes after the price quote expired.
That is not a card fault: it is a chain of parties, your issuer among them, each holding a veto, and several exercising it on principle the moment the merchant category reads crypto, and pay-by-bank deletes most of the chain.
None of this is new and none of it is crypto technology, and in some markets it is already how most people fund an account. This is an educational guide, not financial advice.
What it is
You choose pay-by-bank at checkout, and your bank's app opens, or a browser window belonging to your bank. You see the payee and the amount, you approve with a fingerprint or a passcode, and the money leaves your account immediately.
You never type a card number, and the merchant never handles one. There is no 16-digit credential to be stolen, expire or get blocked, because none was used. The industry calls this a push payment, and the label is exact: you push money out, rather than authorising someone to pull it.
Where the plumbing came from
Two pieces of regulation, neither written with crypto in mind.
The first is open banking: Europe's PSD2 forced banks to open APIs so licensed third parties could, with your consent, see your accounts and initiate payments. The UK ran its own version from 2018 following a competition order, and that is the piece that lets a payment company ask your bank to move money on your instruction.
The second is instant settlement: under the EU's Instant Payments Regulation, every bank payment provider has had to be able to receive instant euro payments since 9 January 2025, and eurozone providers have had to send them since 9 October 2025. Transfers up to 100,000 euros must clear within ten seconds, and providers cannot charge more than for an ordinary SEPA transfer. The UK has had Faster Payments since 2008.
Open banking made the instruction possible, and instant payments made it useful. Before that combination, a bank transfer meant waiting a day, which is intolerable when you are buying an asset whose price moves.
The next revision, PSD3 with its companion regulation, reached political agreement on 27 November 2025 and is expected to apply around early 2028.
Why crypto platforms in particular want it
Because cards are a poor fit for this purchase and everyone in the industry knows it.
Declines. Issuers routinely block or flag crypto merchant categories. TrueLayer, which handles close to half of UK pay-by-bank volume, reports success rates above 95%, well ahead of typical card performance on these purchases.
Cost. Card acceptance on crypto runs high because of chargeback exposure. Bank rails are cheaper, and some of that difference reaches the customer as a lower spread.
No expiry, no limit surprises. Cards get replaced, get maxed, get frozen by fraud engines at 11pm, but an account balance does not expire.
Finality. A pushed payment cannot be charged back, which removes the fraud that made processors nervous about the sector to begin with.
Volt, Trustly and TrueLayer all serve crypto venues among their customers. Trustly has run this model since 2008, and Volt has built specifically around exchanges and high-volume merchants across UK, SEPA and Brazilian rails.
The honest disadvantages
Finality cuts both ways: it is the merchant's favourite feature and it is your missing safety net.
With a card, a merchant that fails to deliver leaves you a dispute route. With pay-by-bank, you authorised a transfer to a named party and it is gone, in the same way a normal bank transfer is gone. Verify the payee name on the approval screen, because that screen is the last checkpoint you get.
The second limitation is the one people misunderstand most: pay-by-bank does not route around your bank, it goes through your bank, more directly than a card does. If your bank has decided it does not like payments to crypto platforms, open banking gives it a cleaner view of exactly where the money is going, not a blind spot. Some banks block or warn on these transfers, and a payment initiated this way is no harder for them to see.
Availability is also uneven: coverage is strong in the UK, the Netherlands, the Nordics and parts of Germany, thinner elsewhere, and in the US the equivalent rails are still catching up.
What it looks like in practice
Pick pay-by-bank and choose your bank from a list. Get bounced into your banking app, which is already logged in on your phone, then check payee, check amount, approve. Bounce back to the merchant, which now shows the payment as received. The whole thing takes under a minute and the crypto is ordered before the price quote expires.
The first time is the slowest, because you may be asked to consent to the connection. After that it is faster than finding your card.
Keep the confirmation, because your bank statement will show a transfer rather than a card purchase, so the reference on the platform's side is what ties the two together if you ever need support to trace an order.
Frequently Asked Questions
It is a bank transfer with the details filled in for you and authorisation handled in your banking app. You are not copying an account number or a reference, which removes the most common cause of misdirected transfers, and on European and UK rails it usually settles in seconds rather than the next working day.
Yes. Open banking routes the payment through your bank rather than around it, so your bank sees the destination clearly. Some banks warn, delay or refuse transfers to crypto platforms. If yours does, changing the payment method rarely helps and speaking to the bank usually does.
No. You pushed the money, so there is nothing for a card scheme to reverse. This is the same position as any bank transfer. Check the payee name and amount on the approval screen, because that is the point at which you can still stop.
Different rather than strictly better. No card details are shared or stored, so there is nothing to skim or leak, and authentication happens inside your own bank's app. Against that, you lose the dispute rights a card gives you, so the security advantage is on data and the disadvantage is on recourse.
It depends on local open banking rules and on instant settlement existing at all. The UK, the Netherlands and the Nordics have deep coverage; other markets are thinner. The EU's instant payment obligations only completed their rollout for sending in October 2025, so several markets are still building on top of them.
