How the Single API Integration Handles Digital Assets

The single API model consolidates several crypto functions into one layer. Banks avoid building separate systems for compliance and brokerage needs entirely. Processing, custody, and regulatory monitoring all route through Nium's own infrastructure.Nium issues cards across four payment networks: Visa, Mastercard, Discover and UATP. The company issues more than 38 million card tokens every year, according to its March 2026 announcement. In October 2022, Nium partnered with Zero Hash for additional crypto capabilities.That partnership brought crypto-to-fiat payment solutions onto the platform directly. It broadened the range of digital asset transaction options for clients. The infrastructure approach reduces time to market for financial institution clients. Clients integrate once and then gain access to all evolving crypto capabilities. Nium handles backend updates without requiring clients to rebuild existing connections. Future roadmap items included stablecoin wallets and crypto payment acceptance features.

Nium's Stablecoin Expansion With Visa and Coinbase

In November 2025, Nium joined Visa's stablecoin settlement pilot program directly. That pilot used Circle's USDC stablecoin for cross-border settlement purposes globally. It marked an early step toward stablecoin integration on major payment rails.By March 2026, Nium launched its stablecoin card issuance platform more broadly. The platform enabled card issuance on both Visa and Mastercard networks globally. That expansion positioned Nium as an early mover in stablecoin-backed card products.Alex Johnson, Chief Payments Officer at Nium, addressed the strategic significance. "By settling with Visa via stablecoins, we're aligning payments to the speed of the internet, not the speed of traditional rails," Johnson said in Nium's November 12, 2025 announcement. The approach aims to reduce settlement delays associated with traditional payment infrastructure.Nium co-founder and Chief Executive Officer Prajit Nanu highlighted the company's stablecoin card offering. "Today, Nium delivers exactly that, on both major payments networks, in every major market, through one integration," Nanu stated in the March 30, 2026 announcement. The platform allows partners to offer stablecoin-backed cards through a single integration.In April 2026, Nium partnered with Coinbase for USDC stablecoin payments across its platform. Coinbase serves as the wallet provider and regulated custodian for the partnership.

This monthly comparison does not mean stablecoins exceeded ACH's annual transaction volume.
