Mastercard announced yesterday it's expanding its global settlement infrastructure to support on-chain settlement using regulated stablecoins. The upgrade lets partner banks and fintechs settle transactions on blockchain networks around the clock — weekends and holidays included. No more waiting for traditional banking windows to clear cross-border payments.
Six stablecoins, eight networks
The initial rollout supports six regulated stablecoins: Circle's USDC, PayPal's PYUSD, Paxos-issued USDG and USDP, Ripple's RLUSD, and SoFi's SoFiUSD. Settlement runs across eight blockchain networks — Ethereum, Solana, Polygon, Base, Arbitrum, the XRP Ledger, Canton, and Tempo. That's a wide net, covering both public chains and permissioned networks like Canton.
Initial partners and regions
Mastercard named five partners that will start using the stablecoin settlement option: ARQ (formerly DolarApp), CBW Bank, Cross River, Lead Bank, and Nuvei. The rollout targets the United States and Latin America first. Broader expansion through the rest of 2026 is planned.
Backend upgrade, not a consumer product
This is a change to Mastercard's settlement layer — cardholders won't notice a difference in how they pay. Stablecoin settlement runs in parallel with traditional fiat settlement. Raj Dhamodharan, Mastercard's EVP for blockchain and digital assets, said the enhancement gives partners more flexibility in liquidity management for an always-on digital economy. Ripple SVP Jack McDonald called the announcement a landmark validation of blockchain technology for critical global payments infrastructure.
The announcement comes as stablecoins increasingly find use in real-world payments and remittances, not just crypto trading. Mastercard's move could pressure other legacy settlement networks to offer similar 24/7 capabilities. For now, the company says the eight chains and six stablecoins are just the start — more networks and tokens are expected as the rollout expands through 2026.
