The partnership will enable Marqeta customers to embed stablecoin payments directly into new and existing financial products without rebuilding core systems or taking on new regulatory burden.

The collaboration comes as stablecoin adoption accelerates across financial services. In February 2026 alone, stablecoin monthly transaction volume hit $7.2 trillion, surpassing the U.S. ACH network ($6.8 trillion) for the first time in history. On zerohash’s platform specifically, transaction volume grew 690% year-over-year in 2025, while transaction frequency was up 208%, underscoring significant growth as stablecoins become embedded in financial workflows. zerohash today supports instant global payouts for platforms including Gusto and Worldpay, as well as real-time account funding for Interactive Brokers, Kalshi, tastytrade, and more.

Marqeta has been a trusted partner for crypto-native companies, powering debit card offerings in the U.S. and Europe that enable users to spend in fiat currency based on crypto holdings and earn rewards back in crypto. The partnership will extend Marqeta’s capabilities, allowing both crypto and non-crypto companies to take advantage of the value of stablecoins through this integration. Marqeta’s platform processed nearly $400 billion of payments volume in 2025, while enabling innovative, global payment experiences across diverse use cases.

The partnership will let users spend digital dollar balances at tens of millions of merchants globally using a standard payment card. Merchants get paid in fiat currency, just as with any other card transaction. zerohash will provide the underlying infrastructure that handles custody, compliance and liquidity for onchain money custody and movement. Concurrently, Marqeta will manage card issuance, acceptance and bank and network relationships. Together, the integration will give platforms a faster, more flexible way to create spendability for stablecoins with real-time settlement and improved capital efficiency.
