Coinbase has partnered with banking software firm Stablecore to bring digital asset custody, trading and stablecoin payments to more than 3,000 community and regional banks and credit unions in the United States. The partnership is already running with its first customer, Texas-based Amarillo National Bank, and lets banks offer the services under their own brands without customers ever touching a crypto exchange.
The deal works in two layers. Stablecore handles integration between core banking, digital banking and compliance systems, while Coinbase supplies the regulated infrastructure underneath, including custody and exchange services. Customers of a participating bank can buy, sell, hold, stake and pay with digital assets through the same app they already use for checking and savings. The bank keeps the customer relationship and puts its own name on the front end.
Second banks push in a month
It is the second community-banking partnership Coinbase has announced in just over a week. On September 10 the company teamed up with payments firm Moov to bring stablecoin acceptance, settlement and real-time funding to Moov’s base of more than 1,000 community banks and credit unions. The Moov deal focuses on payment rails, letting a small bank accept stablecoin payments and settle them in real time without building a crypto stack. The Stablecore deal goes further and adds full custody and trading on top.
Stablecore, founded in 2025, raised $20 million in a September 2025 funding round that included Coinbase Ventures. The company says its existing integrations already reach thousands of US financial institutions, which is what makes the 3,000-bank figure plausible rather than aspirational. Its software connects core banking platforms, digital banking front ends and compliance systems, the plumbing that normally makes new asset classes expensive for small institutions to adopt.
Why community banks care
Community banks and credit unions have watched customer deposits and payment flows drift toward fintech apps and crypto platforms for years. Stablecoin payments in particular threaten card interchange and wire fee income, two of the steadier earners on a small bank’s books. The pitch from Coinbase and Stablecore is defensive as much as offensive: keep the customer relationship by offering the asset class inside the bank’s own product rather than pushing customers out the door to an exchange app.
Regulatory clarity has helped. The GENIUS Act framework for payment stablecoins and the SEC’s recent moves on tokenized securities have given smaller institutions more confidence that crypto services will not trigger examiner backlash. Several large banks rolled out bitcoin and ether custody earlier this year for wealthy clients. This deal aims at the long tail of the US banking system, the thousands of institutions with under $10 billion in assets that have offered nothing crypto-related so far.
Competition in the infrastructure layer is already forming. Q2, a core banking provider used by many US credit unions, announced its own partnership with Stablecore in March to add stablecoin and digital asset capabilities to its platform. Coinbase now appears to be standardizing on Stablecore as its distribution channel into that same market, effectively reaching the same banks through the same integrator.
What customers would actually get
Under the arrangement, a credit union member could hold bitcoin or ether alongside a checking account, send stablecoin payments to a vendor, and stake supported assets, all billed through the bank. Stablecore orchestrates the compliance checks, including know-your-customer data the bank already holds, while Coinbase provides custody and trade execution behind the scenes. The customer never opens a Coinbase account, and the bank never runs a blockchain node.
That model mirrors what crypto firms have done in Europe under MiCA, where regulated providers white-label services to local banks. In the US it has been slower to arrive, partly because custody rules for state-chartered banks remained murky until federal guidance firmed up this year. Coinbase’s custody arm already serves institutional clients and several spot bitcoin ETFs, so the operational side is established. The new part is packaging it for a bank with 40 employees and no digital asset team.
Pricing for end customers has not been published. Community banks typically mark up wholesale services, so a bitcoin purchase through a credit union will likely cost more than the same trade on a retail exchange. Whether customers accept that premium for convenience is the open question the pilot at Amarillo National Bank is meant to answer. Bankers also have to decide how much of the balance sheet, if any, they want exposed to a volatile asset class sitting next to mortgages and farm loans.
The economics for the banks themselves remain unproven. Community banks are historically slow adopters, and demand from customers in smaller markets is uncertain. Fee splits between Coinbase, Stablecore and the participating bank have not been disclosed. But for Coinbase the strategic value is clear: regulated distribution channels that crypto-native competitors cannot easily replicate, secured at a moment when stablecoin legislation has made bank-grade compliance a selling point rather than a cost.
Neither company disclosed financial terms or a rollout timeline beyond the live Amarillo National Bank deployment. More bank names are expected to be added in the coming months as integrations complete. If the pilot converts at a reasonable rate, the deal could put a crypto counter inside a meaningful share of America’s 4,000-plus community banks within two years, a distribution reach no exchange has managed through its own app alone. For the banks, the bet is smaller: a modest new fee line against the risk of doing nothing while deposits and payments keep migrating to platforms that already speak crypto.
