Mastercard expands stablecoin settlement as crypto rails keep moving into the real world

Mastercard is expanding its settlement capabilities to support regulated stablecoins, another sign that crypto infrastructure is becoming more useful outside of pure speculation. The company said the new framework will support USDC, PYUSD, RLUSD, and other stablecoins across multiple blockchain networks, giving issuers and acquirers more flexibility in how they settle transactions.

A key part of the update is timing. Mastercard’s new setup will support intraday, weekend, and holiday settlement, which can make liquidity management easier for payment partners and businesses that need faster movement of funds. That kind of flexibility is one of the main advantages stablecoins have over traditional settlement systems.

The broader trend is clear: stablecoins are increasingly being used as payment and settlement rails rather than just trading assets. Mastercard’s recent New York BitLicense approval also shows that this push is being built inside a regulated framework.

The supported assets include Circle’s USDC, Paxos-issued PYUSD and USDP, Ripple’s RLUSD, plus USDG and SoFiUSD. Mastercard said these will be available across networks including Ethereum, Solana, Polygon, Base, Arbitrum, Canton, Tempo, and XRPL.

The rollout comes as other major players continue to move in the same direction, including Visa, MoneyGram, and Western Union.

In that environment, platforms like Keytom fit naturally, especially where users want easier access to multiple stablecoins and cross-chain movement without having to manage each network separately.
