Coinbase and Marqeta link stablecoins to business payment cards

Marqeta and Coinbase announced a collaboration on Oct. 16 to let Marqeta business customers offer cards funded by users’ stablecoin balances. The arrangement links Coinbase’s custody and conversion services with Marqeta’s card issuing and payment processing, according to Marqeta’s announcement distributed by Business Wire. It extends a relationship in which Marqeta already issues crypto-backed cards for Coinbase.

How does a stablecoin balance become card spending?

Coinbase will hold the stablecoin balances and manage conversion between digital assets and fiat currency. Marqeta will issue the cards, process payments, and manage the bank and payment network relationships. Base, Coinbase’s blockchain, will provide the on-chain settlement infrastructure.

In practical terms, a cardholder spends against a stablecoin balance at a merchant that accepts cards. The card payment still runs through the familiar card system, while the companies’ services connect that purchase to digital assets behind the scenes. Think of it as a handoff: Coinbase handles the digital money, and Marqeta handles the card transaction.

Who can use the cards, and what changes for businesses?

The collaboration is aimed at Marqeta’s enterprise customers, including crypto-native and traditional businesses. Those businesses will be able to issue stablecoin-backed cards and fund their card programs 24 hours a day, seven days a week. Cardholders will be able to spend at millions of merchants globally that accept cards, the companies said.

The announcement describes the division of work, but does not identify which stablecoins will be supported or explain the precise transaction sequence between authorization, conversion, and settlement. It also gives no launch date or fee details. The service is a planned collaboration, so the announcement does not establish that cards are available now.

What role does Base play in the payment?

Base is the on-chain settlement layer in the arrangement. The companies say it will provide infrastructure for settlement that is fast, secure, and low-cost. Coinbase’s custody and conversion functions sit alongside that blockchain layer; Marqeta’s issuing and processing functions connect the product to banks, card networks, and merchants.

That split matters because a stablecoin balance alone does not make a payment card work. The card program needs a way to hold the digital funds, convert them to fiat when required, settle on-chain, and process a purchase through conventional payment infrastructure. The plan assigns those jobs across Coinbase, Base, and Marqeta, bringing stablecoin balances into a card product without changing where cardholders can spend. Marqeta and Coinbase have worked together on Coinbase’s own crypto-backed cards; this collaboration extends that relationship to other Marqeta enterprise customers.
