Citi has extended its Spring merchant platform to let institutional clients receive stablecoin payments without holding the digital assets themselves. The new workflow relies on Coinbase, which automatically swaps the tokens for fiat and passes the funds to Citi for final settlement.
Integration of Coinbase with Spring by Citi
The partnership deepens a collaboration first announced in October 2025. Coinbase’s payments stack now plugs directly into Citi’s Spring platform, enabling merchants that bank with Citi to present a stablecoin option at checkout. When a customer pays with a token such as USDC, Coinbase’s infrastructure converts the amount into U.S. dollars in real time. Citi then records the transaction as a standard fiat payment, acting as the bank of record.
Coinbase Virtual Accounts Powered by Citi’s Banking-as-a-Service
In parallel, Coinbase is leveraging Citi’s Virtual Account Wallet, a component of the bank’s BaaS offering, to create what Coinbase calls Virtual Accounts. These accounts behave like traditional bank accounts for businesses building on Coinbase: inbound fiat is automatically tokenized into stablecoins, while outbound transfers can be sent as either fiat or stablecoins. The feature is designed to simplify cash management for firms that need both on-chain liquidity and conventional banking services.
Scope and Future Rollout
Both capabilities are initially available only in the United States, with the companies indicating that additional features will be introduced over the coming months. Coinbase estimates the addressable market to exceed 150 million stablecoin holders worldwide, suggesting a sizable pool of potential users once the service expands beyond the U.S. borders.
Strategic Context for Both Firms
For Citi, the move represents a concrete step toward broader digital-asset services, complementing its earlier announcement to add Bitcoin custody to its Custody+ suite. Coinbase, meanwhile, continues to diversify beyond its core exchange business, having recently launched fixed-rate USDC loans backed by Bitcoin and tokenized stocks on its Base layer-2 network.
Why it matters
The integration bridges a regulatory gap by allowing regulated banks to facilitate crypto-based commerce without exposing their clients to direct token custody. By converting stablecoins to fiat before settlement, Citi maintains its traditional banking controls while offering merchants a modern, 24/7 payment method. This could accelerate the adoption of stablecoins in everyday commerce and set a precedent for future collaborations between legacy financial institutions and crypto platforms.
