How to Buy USDC with a US Bank Transfer (ACH)

Why a bank-transfer onramp matters

Not everyone wants to buy crypto with a debit card. Cards come with purchase limits, card-network fees, and, depending on your bank, outright blocks on crypto-related purchases. And for anyone moving a meaningful amount of money — funding a wallet the way you'd fund a brokerage account — a card was never really the right tool to begin with.

A direct ACH link from your own bank is how most people already move money to Fidelity, Robinhood, or any other brokerage. It's a familiar pattern: connect your bank, authorize a transfer, and the funds show up where you sent them. FAX brings that same pattern to funding a stablecoin wallet, using Brale, a regulated stablecoin issuer and orchestration platform, to handle the transfer on the backend.

How it works, step by step

Funding your FAX wallet by bank transfer takes three steps:

Open Deposit in FAX. From your wallet, choose the bank-transfer funding option.
Link your bank via Plaid. Plaid is the same bank-connection technology used by apps like Venmo and Robinhood. You log in through Plaid's secure connection flow — FAX never sees your bank password.
Choose an amount and confirm. FAX initiates an ACH debit from your linked account. USDC arrives in your wallet within 1-3 business days, which is standard ACH settlement timing.

That's it — no card to enter, no card issuer to flag the transaction as suspicious, no purchase cap to bump against.

On bank-linking security

Plaid is the connection layer behind thousands of fintech apps, including many of the brokerages and neobanks you may already use. When you link your account, you authenticate directly with your bank through Plaid's flow — you never hand FAX your bank password, and FAX never stores it.

Who this is for — ACH vs. an instant card buy

FAX also supports instant card-based buys for smaller amounts, so you're not stuck waiting days for every deposit. The two paths are built for different situations:

Bank transfer (ACH)	Larger, planned deposits — 1-3 business days to settle, no card-network fees
Card-based buy	Smaller, urgent deposits — instant, but subject to card limits and fees

If you're funding your wallet ahead of a trip, a rent payment, or just moving savings into stablecoins, ACH is the more direct route. If you need money in your wallet in the next five minutes, use the card option instead.

Your funds go straight to your own wallet

The USDC you buy this way lands directly in your own self-custody FAX wallet. Brale registers your existing wallet address as the destination for the transfer — it doesn't sit as a custodian holding your money in an intermediary account along the way. Your bank account funds your own wallet, directly.

What to do once you're funded

Funding is just the first step. Once your USDC balance is sitting in FAX, a lot of users either put it to work right away — paying a Pix key in Brazil directly from a USDC balance — or let idle balance earn yield instead of sitting flat.

Frequently asked questions

How long does an ACH transfer take?+

ACH debit is standard bank-transfer speed, not instant — typically 1-3 business days from the moment you approve the transfer to when USDC lands in your FAX wallet. If you need funds sooner, FAX also supports instant card-based buys for smaller amounts.

Is my bank information safe?+

Yes. FAX's ACH onramp is powered by Brale, a regulated stablecoin issuer and orchestration platform, and bank linking runs through Plaid, the same bank-connection technology used by apps like Venmo and Robinhood. You never type your bank password into FAX directly — Plaid handles the connection, and FAX never sees your banking credentials.

Does this work with non-US bank accounts?+

Not today. This specific ACH bank-transfer rail is available for US bank accounts only. FAX's onramp options vary by where your bank account is, so what's available to you depends on your declared banking country.

Is there a faster way to buy USDC?+

Yes. Alongside ACH, FAX also supports instant card-based buys for smaller amounts — useful when you need funds in the next few minutes rather than the next few days. ACH is the better choice for larger, planned deposits since it's a direct bank transfer without card-network fees.
