Coinbase Institutional and Citi announced an expansion of their partnership on September 28, 2026, aimed at developing a stablecoin infrastructure stack. The initiative combines Citi’s regulated banking capabilities with Coinbase’s digital asset payment rails to bridge traditional finance and crypto markets.

The collaboration features two primary components: Coinbase has selected Citi’s Virtual Account Wallet to power Coinbase Virtual Accounts, enabling automatic conversion of incoming fiat into stablecoins via Citi’s infrastructure. Additionally, Coinbase’s payments technology will allow merchants using Spring by Citi to accept stablecoin payments at checkout. In this arrangement, Coinbase converts received stablecoins into fiat, while Citi settles the funds as the bank of record. The service is scheduled for an initial launch in the United States, with further capabilities expected in subsequent months.
