Zero Hash and Marqeta (NASDAQ: MQ) announced a partnership to integrate Zero Hash's stablecoin infrastructure into Marqeta's card issuing platform, according to a press release issued July 22, 2026.

The integration is designed to allow Marqeta customers to embed stablecoin payments into financial products without rebuilding existing systems. Users will be able to spend digital dollar balances at merchants globally using a standard payment card, with merchants receiving fiat currency as in any standard card transaction.

Under the arrangement, Zero Hash will handle custody, compliance, and liquidity for on-chain money movement, while Marqeta will manage card issuance, acceptance, and bank and network relationships.

Marqeta's platform processed nearly $400 billion in payments volume in 2025. Zero Hash reported 690% year-over-year transaction volume growth and 208% growth in transaction frequency on its platform in 2025. The company currently supports payouts for platforms including Gusto and Worldpay, and account funding for Interactive Brokers, Kalshi, and tastytrade.

"By integrating with zerohash, we will be able to give our customers a full solution to deliver multinational and stablecoin-backed card programs that meet the needs of their users, while also being compliant and ready for global scale," said Anthony Peculic, Interim Chief Product Officer at Marqeta.

"Compatibility between stablecoins and traditional payment networks is a critical unlock for users' onchain money, while also opening new opportunities for traditional businesses through stablecoin-backed cards," said Edward Woodford, Founder and CEO of Zero Hash.

The press release noted that in February 2026, stablecoin monthly transaction volume reached $7.2 trillion, compared with $6.8 trillion processed by the U.S. ACH network during the same period.
