One balance for
fiat and crypto.
1Cpay gives you IBANs, cards, and crypto swaps under a single account — so your euros and your USDT stop living in different apps.
Everything a modern account needs. Nothing it doesn't.
Fiat rails and crypto rails, built on the same ledger — not bolted together after the fact.
Personal IBANs
Apply for a dedicated IBAN, subject to KYC/KYB review and acceptance by Swiss Fiat AG.
Crypto swap
Convert between BTC, ETH, USDT, USDC, TRX and SOL at live rates, without leaving your account.
Cards
Virtual cards for online spend. Physical cards, subject to availability, draw from the same balance.
Real-time ledger
Track your SEPA transfers, swaps and card activity from one account.
Skip the exchange. Swap straight from your balance.
No withdrawing to an external exchange and back. Pick the pair, confirm, and the new asset lands in your balance.
- Transparent, live market rates
- Supports BTC, ETH, USDT, USDC, TRX and SOL
- Works the same for fiat-to-crypto and crypto-to-crypto
Three steps, no branch visit.
Every account is subject to KYC/KYB review and acceptance by Swiss Fiat AG.
Open your account
Complete identity verification to apply for your account and get your IBAN and wallet addresses, subject to KYC/KYB review and acceptance by Swiss Fiat AG.
Fund it your way
Top up by SEPA transfer, or by sending crypto directly to your account.
Swap, spend, send
Move between currencies, pay with your card, or send funds — all from one balance.
Money without borders, currency without limits.
Open a 1Cpay account and hold fiat and crypto side by side, for the first time in one place.
