When people ask what will get normal people to hold stablecoins as their main balance, they usually expect the answer to be checkout buttons or crypto debit cards.

Debit at the register is already a mostly solved problem. Visa has reported more than 160 stablecoin-linked card programs. You tap a card at a coffee shop, the program converts your stablecoin balance behind the scenes, and the merchant sees an ordinary card payment.

That is convenient, and it barely changes where anyone keeps their money. Nobody switches banks because they got a new debit card. Most people who manage their money carefully don't want to swipe debit in the first place—they put everyday spend on a credit card for the points, fraud protection, and dispute rights, and then they pay the statement balance off once a month.

So the real question isn't whether you can spend stablecoins at a terminal. It's whether a stablecoin balance can answer the monthly bills that pull from your checking account automatically.

How paying a credit card with crypto works today

Right now it works with an asterisk. Major card issuers don't accept USDC or other stablecoins directly; something in the middle converts the tokens into dollars and sends fiat to the biller.

Two public examples show where the market is today:

• Spritz lets US users pay credit cards, mortgages, phone bills, utilities, and auto or student loans from a non-custodial wallet. You pick the bill, push the stablecoins from your wallet, and Spritz pays the biller in dollars.
• Coinbase One Card runs on the American Express network for Coinbase One members and lets you pay the card balance from your Coinbase account, including crypto that converts to dollars.

Both are useful. Notice what they share, though: the user initiates a push payment or holds funds inside a single platform's walled garden.

That isn't how most people run their household finances. Most people turn on autopay once on their card issuer's website and forget about it. And autopay runs in the opposite direction.

Autopay is a pull, not a push

When you turn on statement autopay with Chase, Amex, or Capital One, you type in a bank routing number and checking account number. Once a month, the card issuer originates an ACH debit against that account. It pulls the money; you don't push anything.

That single mechanism is how recurring money moves in the United States. Nacha reported 35.19 billion ACH payments in 2025, and 19.59 billion of them were debits. Credit card statements, rent portals, electric utilities, tax agencies, and insurance carriers all rely on the same assumption: give us a routing and account number, and we will pull what you owe on the due date.

An on-chain wallet doesn't fit that shape. It has a public key, not a routing number, and nothing on a public blockchain works like an unscheduled ACH debit mandate by default.

What it takes to make a wallet answer an ACH debit

I've worked on bank-side payment systems, and the seam between a 24/7 token ledger and batch ACH rails is where all the real engineering lives. Whatever sits between the biller and the wallet has to do four things cleanly every time:

1. Give the biller a real bank routing and account number. To the card issuer or utility company, the destination has to look like a standard demand deposit account (DDA) on the Federal Reserve's ACH network.

2. Bridge an empty DDA to a live token balance. When an incoming ACH debit arrives in a batch file, the system has to map that bank account to the user's wallet, verify that the spendable stablecoin balance covers the pull, burn or convert the tokens, and move fiat from the reserve into the DDA before the settlement window closes.

3. Race the two-day return clock. If the wallet doesn't have enough tokens to cover the debit, the receiving bank has to return the item. Under Nacha rules, an insufficient-funds return (R01) generally has to be transmitted back within two banking days of settlement. Miss that cutoff and the institution sitting in the middle eats the credit risk.

4. Handle the 60-day reversal tail. On-chain transfers are final in seconds; consumer ACH debits are not. Under Nacha rules, a consumer can claim an ACH debit was unauthorized (R10) up to 60 calendar days after settlement, and a biller can re-initiate a bounced insufficient-funds debit up to two additional times.

Add the timing mismatch—self-custody wallets move 24/7/365, while ACH files settle in weekday banking windows—and you see why most teams build a simple debit card first. Moving tokens is easy. Acting like the bank account the ACH network expects while the user's money lives on open rails is hard systems work.

When checking becomes a pass-through

Once an ACH pull can settle reliably against a stablecoin balance, how you use a bank changes overnight:

1. You swipe your normal credit card all month for rewards and chargeback protection.
2. On statement day, the card issuer pulls the full balance over ACH like it always has.
3. The pull settles automatically from your stablecoins.

At that point, a traditional checking account stops being the place where your money sits. It turns into a dumb pass-through—a legacy routing number that exists only because utility companies and card issuers still speak ACH.

The same plumbing covers rent, electric bills, and insurance premiums that charge a 3% fee for cards or demand a bank account. You stop leaving thousands of idle dollars trapped in a zero-interest checking account "just in case rent pulls before Friday."

And it reinforces the healthiest credit habit. Federal Reserve G.19 data puts the average interest rate on credit card accounts assessed interest at 22.36% APR. The only winning way to use a credit card is autopay in full every month. Making autopay work natively off stablecoins aligns self-custody with how financially disciplined people already pay their bills.

For businesses: an LLC and an on-chain operating account

On the business side, the shift is already happening. Brian Armstrong put it plainly on X:

Every business needs a stablecoin strategy. The ones that move first will win customers.

For a small company or startup, the practical first step is opening an operating account like Coinbase Business under your LLC so the company has a clean deposit address on its books. That lets a business:

• Take instant payouts from global clients and platforms without waiting three days on an international wire or losing a cut to FX spreads.
• Get final settlement on high-ticket invoices with zero chargeback risk once the transaction confirms on-chain.
• Spin up direct payment links and checkouts without a middleman holding a 120-day rolling reserve.

Even there, the last mile is the same. A business holding stablecoins still has landlords, tax authorities, and legacy vendors that insist on pulling via ACH.

Checkout buttons get the demos. Making a wallet answer a boring monthly ACH debit is what lets people leave the old banking stack behind.
