Onramper does not sell you crypto. It is a router: when you buy through an app that uses it, Onramper picks a provider and hands the transaction over to them.
So your money never touches Onramper, it holds nothing on your behalf, and it keeps no record you can retrieve. The purchase happened with somebody else.
Your job, then, is to work out who that somebody was.
What you get out of the box
Choisissez votre méthode d'import.
Working out who served you
- Search your email around the date of the purchase. The provider that handled it will have sent its own receipt under its own name.
- Check your bank or card statement. The merchant name on the charge is usually the provider rather than Onramper.
- Then follow the guide for whichever provider that turns out to be.
On Kryptos
- Log in to Kryptos.
- Go to Integrations.
- Click Add Integration, then search for and select Onramper.
- Click the Onramper icon and choose Upload CSV.
- Upload the file. Kryptos reads it and categorises the transactions for you.
Good to know
- Onramper holds no funds and keeps no history you can export.
- The provider that served you is often MoonPay or Transak, but it varies by transaction.
- Your card statement usually names the real provider, which is the quickest way to identify them.
Finding out who you really bought from
Onramper is infrastructure that sits between an app and a set of crypto sellers. When you press buy, it picks one, based on your country, your payment method and the rate, and passes you to them.
The consequence is that Onramper is not a party to your purchase in any way that matters for records. It does not take your money, does not hold your crypto, does not keep your identity documents and does not maintain a history you could export. There is no account to log into.
Which sounds unhelpful, but it points at the answer: your record exists, it is just filed under somebody else's name. Two things will tell you whose.
The first is your bank or card statement. The charge is almost always in the name of the company that sold you the crypto, not Onramper. The second is your email, where that provider will have sent its own confirmation.
Once you know who it was, follow their guide. It is often MoonPay or Transak, both of which are covered here, though the routing genuinely varies from one purchase to the next, so a series of buys in the same app can involve more than one company. For how cost basis works where you file, see the USA crypto tax guide or the UK crypto tax guide.

Tracing a purchase to its real provider
The charge on your statement and the receipt in your email both name whoever sold you the crypto.
Explaining crypto with no obvious source
If coins arrived and nothing in your records accounts for them, an Onramper-routed purchase is a likely explanation.
Handling purchases across several providers
Because routing varies per transaction, a run of purchases through one app can involve more than one provider.

The purchase is with the provider, not with Onramper
Whoever Onramper routed you to is the party you transacted with, and their record is the one that matters for cost basis.
Different purchases can involve different providers
Routing is decided per transaction, so several purchases through the same app may have been handled by different companies with different records.
The purchase still sets your cost
Whichever provider handled it, buying fixes what the coins cost you, and that is what a later disposal is measured against.
Use the amount your bank was charged
That figure captures the whole cost regardless of which provider was involved and how they itemised it.

- Kryptos never asks for your password or login details
- Delete an import at any time and its data goes with it
- Keep the original file: it is your evidence if anyone asks later
Si la synchronisation échoue.
There is not one. Onramper routes transactions rather than holding accounts, so nothing exists to log into.
Check the merchant name on your card statement and search your email around that date. The real provider sent its own receipt.
That is expected. Routing is chosen per transaction, so it can vary between purchases made in the same app.
