- Free dedicated USD account — receive Wire or ACH like any US bank account.
- Instant conversion — USD to USDC/USDT, settled on Bridge custodial infrastructure.
- On-chain withdrawal — send USDC to your own wallet on Solana, Ethereum, Base or Polygon.
- Regulated & compliant — Bridge money transmission + Didit KYC in under a minute.
- Zero monthly fees — no subscription, no maintenance, no hidden spreads.
Step-by-step: USD to crypto on 1TCH
Step 1 — Open your free USD account
Register and pass KYC in under 60 seconds. You instantly receive a dedicated USD account with a real account and routing number — ready to receive Wire or ACH transfers from any US bank.
Step 2 — Fund via Wire or ACH
Send USD from your bank to your 1TCH account. Wire transfers settle same-day; ACH typically lands within hours. Funds are held as USDB (Bridge custodial balance) and available immediately for conversion.
Step 3 — Convert and withdraw on-chain
Choose your destination stablecoin (USDC or USDT) and chain:
- Solana — near-zero fees, sub-second confirmation.
- Ethereum — maximum liquidity and ecosystem reach.
- Base — low-cost, Ethereum-secured L2.
- Polygon — fast, inexpensive global transfers.
Enter your own on-chain wallet address and confirm with 2FA. The USDC lands in your wallet in seconds.
