Payment giant Visa announced yesterday that USDC settlement services are now live in the US mainland, with the first partner banks being Cross River Bank and Lead Bank. This directly fills the long-standing weekend liquidity gap of FedWire and SWIFT, with stablecoin settlement funds of $3.5 billion annually now available for 24/7 on the Solana chain.

On-Chain Settlement Breaks Weekend Vacuum

We know that traditional finance enters “sleep mode” after 5 p.m. on Friday, and funds usually cannot be settled until Monday. According to Visa’s official statement, USDC settlement allows issuing and acquiring banks to use blockchain finality, enabling real-time account credits even on weekends.

• 7-Day Settlement Window: Improves the speed and liquidity of weekly settlements for banks and fintech companies, replacing the traditional 5-business-day settlement window.
• Modernized Liquidity and Fund Management: Enables automated, next-generation fund operations for banking participants.
• Interoperability: Connects traditional payment channels with blockchain-based infrastructure.

From Payment Network to Validator

Visa revealed that it will set up proprietary validation nodes on Circle’s newly developed Layer 1 chain, Arc, extending the role of the payment network into the infrastructure layer. This signifies that Visa is gradually upgrading from a simple clearing intermediary to a blockchain operator.

Meanwhile, Cross River Bank and Lead Bank have integrated their deposit and withdrawal APIs with Visa, allowing fintech clients to facilitate bidirectional flows of USD and USDC through the same pipeline.

The Next Step for Banks

Rubail Birwadker, Visa’s Global Growth Officer, stated that partner banks are “not just asking questions—they are preparing to go live.” For banks, adopting on-chain settlement is no longer an innovative option but a necessary course; only the adaptable will survive, especially as consumers no longer want to wait through a weekend.
