Buy Crypto with a Fiat Bank Transfer — No Crypto Exchange Needed
The old way: bank → exchange → wallet
Buying crypto with a bank transfer usually means a three-hop journey: send fiat from your bank to a crypto exchange, place a buy order, then withdraw the crypto to your own wallet. Each hop has friction:
- Exchange onboarding (another KYC, another account to secure)
- Trading fees and bid-ask spreads
- Withdrawal limits and network fees
- Delays — bank transfers can take 1–3 business days to reach the exchange
If your goal is simply to hold or send USDC, there's a shorter path that skips the exchange entirely.
The new way: bank transfer → USDC, directly
1TCH lets you buy USDC with a standard fiat bank transfer — no exchange account, no order book, no spread to monitor. Here's how it works:
- 1. Open a free 1TCH account and complete identity verification (under a minute via Didit).
- 2. Open a FIAT on-ramp account in USD, EUR, GBP or MXN. You receive real banking details (routing number, IBAN, or sort code).
- 3. Send a bank transfer — Wire, ACH, SEPA, Faster Payments or SPEI — to that account from any bank.
- 4. The transfer is auto-converted to USDB in your custodial wallet.
- 5. Withdraw USDC on-chain to any wallet on Ethereum, Solana, Base, Polygon and more.
That's one bank transfer in, one on-chain withdrawal out. No exchange in the middle.
Why this is cheaper
When you buy USDC through an exchange, you pay: a trading fee (often 0.1–1.5%), a spread baked into the price, and a withdrawal fee. With 1TCH, the conversion is automatic and there's no order book — so there's no trading fee and no spread to pay on the conversion itself. You pay standard bank transfer fees to send the fiat, and standard network gas to withdraw on-chain. That's it.
Why this is safer
Using an exchange means trusting a third party to hold your funds between the fiat transfer and the crypto withdrawal. Exchange outages, withdrawal freezes, and account lockouts are well-documented risks. With 1TCH:
- Your fiat lands in a dedicated account in your name.
- Conversion to USDB happens automatically — no manual order that can fail or be delayed.
- USDC is held in your custodial wallet and can be withdrawn on-chain at any time.
- Every action is protected by optional two-factor authentication and a full audit trail.
Which bank transfers work?
1TCH supports the payment rails that matter for global business:
- USD: Wire transfer and ACH
- EUR: SEPA transfer
- GBP: UK Faster Payments
- MXN: SPEI
Because each currency has a local account with local details, senders pay domestic transfer rates — not international wire fees.
Which chains can you withdraw to?
Once your fiat is converted to USDB, you can send USDC to any supported chain, including Ethereum, Solana, Base, Polygon, Arbitrum and Optimism. Choose the chain that matches your recipient's wallet or your own cold storage.
Who is this for?
- Crypto-curious businesses that want USDC without running an exchange account.
- Freelancers paid in fiat who want to hold or send stablecoins.
- Treasury teams moving fiat reserves into stablecoins for yield or on-chain deployment.
- Anyone who's ever been frustrated by exchange onboarding just to buy USDC.
