How does Visa settle using USDC?

TLDR

Visa now lets approved banks settle their obligations to Visa in USDC (USDC) by sending stablecoin transfers over public blockchains, starting with Solana, with rollout expanding in 2026 per a major payments update.

1. Mechanism: issuer/acquirer banks transfer USDC on Solana to meet daily settlement with Visa, replacing some fiat bank transfers per a network announcement.
2. Benefits: faster funds movement and seven?day settlement windows without changing cardholder experience per a finance report.
3. Scope: initial partners Cross River Bank and Lead Bank; program at a $3.5 billion annualized run rate, with Arc L1 support planned per a market update.

Deep Dive

1. Settlement Flow

Visas approved issuers and acquirers settle what they owe Visa by transferring USDC over the Solana network into designated settlement accounts, rather than relying solely on traditional bank wires. The network reconciles these on?chain transfers against obligations, just like fiat settlement, but with programmable treasury flows and on?chain finality per a network announcement.

• The U.S. rollout begins on Solana, with more partners added through 2026 per a market update.
• Visa plans to use Arc, Circles high?throughput L1, for future USDC settlement and to operate a validator when Arc goes live per the same update.

2. Operational Benefits

USDC settlement enables near?instant funds movement and seven?day windows (including weekends and holidays), improving liquidity timing, while the cardholder experience stays the same per a finance report.

• Treasury teams gain programmability for intraday liquidity and automated reconciliation per a market summary.
• The framework sits alongside legacy rails so institutions can mix fiat and stablecoin settlement as needed per the finance report above.

3. Rollout And Infrastructure

Cross River Bank and Lead Bank are the first U.S. participants, and broader availability is planned through 2026, with program volume already at a $3.5 billion annualized run rate per a market update.

• The U.S. launch builds on pilots since 2021 and formal stablecoin settlement starting 2023 per a network announcement.
• Visa intends to support Arc for USDC settlement and validate the network, deepening its infrastructure role per the market update above.

Conclusion

Visas USDC settlement uses on?chain transfers to meet issuer/acquirer obligations with faster, programmable treasury flows, while keeping the consumer card experience unchanged. If expansion continues and Arc comes online, the mix of fiat and stablecoin settlement could materially improve liquidity timing and weekend resiliency for banks.
