Coinbase and Citi link bank rails to stablecoin payments for merchants

Coinbase Global and Citi have launched new features linking the bank's payment systems with Coinbase's stablecoin infrastructure. Citi's Virtual Account Wallet for Coinbase will automatically convert client fiat balances into stablecoins and convert incoming stablecoins back into fiat. Merchants using Citi's Spring platform can now accept stablecoin payments whilst keeping settlement within Citi's regulated banking system. The partnership supports Coinbase's strategy to reduce reliance on trading fees by expanding subscription and service revenue, including payments infrastructure and custody services. The rollout targets US merchants and enterprises. Adoption rates, active user numbers, and processed transaction volumes will indicate the partnership's success. The move aligns with Coinbase positioning itself as an institutional gateway as payments shift onto blockchain infrastructure.

IPID raises $16M to tackle payment fraud expected to reach $331B by 2027

International Payments Identity has raised $16 million in Series A funding led by Foundation Capital, with participation from Citi, HSBC, and existing investors. The payment intelligence firm addresses insufficient payment verification as digital transactions accelerate globally. IPID highlights that information flow lags behind payment system advancements, leaving institutions uncertain about recipients. This verification gap increases fraud vulnerability, with losses projected to reach $331 billion by 2027. The company currently operates bank account verification across more than 50 countries and plans to expand into US payments and digital assets. The funding will strengthen its global network and improve payment decision-making capabilities for financial institutions.
