Mastercard (NYSE: $MA) is widening its settlement window to nights, weekends and holidays, with Polygon (CRYPTO: $POL) selected as one of the networks carrying the card giant’s onchain settlement push.
The expansion gives issuers and acquirers more flexibility in how they settle card transactions across Mastercard’s global network. The new options include intraday, weekend, and holiday settlement, along with regulated stablecoin settlement that can sit alongside existing fiat processes rather than replace them outright.
Polygon said it has been selected to carry that settlement onchain for Mastercard, placing the network inside a broader group of supported blockchains that also includes Arbitrum (CRYPTO: $ARB), Base (CRYPTO: $BASE), Canton (CRYPTO: $CC), Ethereum (CRYPTO: $ETH), Solana (CRYPTO: $SOL), Tempo and XRPL. Mastercard’s supported stablecoins include Circle’s USDC (CRYPTO: $USDC), Paxos-issued PYUSD (CRYPTO: $PYUSD), USDG and USDP, Ripple’s RLUSD and SoFi’s SoFiUSD.

The first wave is expected to include ARQ, CBW Bank, Cross River, Lead Bank and Nuvei in the United States and Latin America, with additional expansion planned through 2026. The setup is aimed at use cases where timing, liquidity and transparency are especially important, including cross-border payments, treasury operations and payouts.
For Polygon, the announcement adds another institutional payments use case at a time when stablecoin activity has become one of the clearest areas of blockchain adoption. Polygon said it processed $79 billion in stablecoin volume in May, representing 26% of stablecoin activity across chains and putting it ahead of BNB Chain and Solana for the month.
The network is also using the Mastercard integration to frame its Open Money Stack as enterprise infrastructure for regulated money movement. Polygon says the chain supports more than 3,800 transactions per second, with fees that remain a fraction of a cent.
Mastercard is not presenting stablecoin settlement as a separate crypto experiment. It is trying to fold digital-asset rails into the settlement infrastructure that banks and payment companies already use.
Polygon (CRYPTO: POL) is currently trading at $0.094 U.S. per digital token.
