Mastercard on Tuesday opened its global card-settlement network to regulated stablecoins, a move that lets issuers and acquirers clear transactions directly onchain. The network now supports eight blockchains and adds intraday, weekend and holiday settlement cycles for the first time.
The eight chains
Mastercard didn't name the specific blockchains in its announcement, but the company has previously worked with public networks like Ethereum and Solana through its Multi-Token Network initiative. The eight chains selected for this rollout are all compatible with the firm's existing crypto card programs, meaning the settlement rails can handle stablecoin-denominated payments without forcing users off the traditional Visa-Mastercard loop.
Settlement cycles expand
Until now, card settlements in crypto mostly cleared on a T+1 or T+2 schedule — same as fiat. Adding intraday, weekend and holiday cycles changes that. Merchants and acquirers can now settle in stablecoins around the clock, which cuts the float risk that builds when banks are closed. For an industry that never stops trading, the timing matters.
Stablecoin regulation angle
Mastercard is only opening the network to regulated stablecoins — meaning those issued by licensed firms under frameworks like the EU's MiCA or New York's BitLicense. That distinction is deliberate. The company has been wary of unbacked or loosely governed tokens since the 2022 collapses. By tying settlement access to regulatory status, Mastercard effectively draws a line between compliant stablecoins and the rest of the market.
The announcement didn't name specific stablecoins either, but USDC and EURC (both issued by Circle under a New York trust charter) are the obvious candidates. PayPal's PYUSD and perhaps a few MiCA-licensed euro stablecoins could follow.
What this means for crypto cards
This isn't a consumer-facing product. It's infrastructure. Crypto card programs — the kind that let you spend Bitcoin or USDC at a coffee shop — have historically relied on a messy backend: the card issuer converts crypto to fiat before settling through traditional rails. Mastercard's onchain settlement removes that conversion step for the acquirer and issuer, cutting costs and settlement latency. Whether that savings reaches the end user is up to the card programs themselves.
Mastercard said the service is live now for participating issuers and acquirers. No word yet on whether Visa plans a similar move.
