Mastercard Adds Stablecoin Settlement on Solana and Other Chains
Mastercard expands its settlement to regulated stablecoins on several blockchains, including Solana. This enables around-the-clock settlement — including weekends and holidays.
What Mastercard Announced
Mastercard announced on June 3, 2026 that it is expanding its settlement network to include regulated, US-dollar-backed stablecoins. Settlement runs across multiple blockchains — Solana is one of the named networks, alongside Ethereum, Polygon, Base, Arbitrum, and XRPL, among others.
Important context: this is a multi-chain expansion. Solana is one of several supported networks, not the only one.
Which Stablecoins and Networks
According to the announcement, support covers several regulated stablecoins, including:
- USDC (Circle)
- PYUSD, USDG, and USDP (Paxos)
- RLUSD (Ripple) and SoFiUSD
These run across a range of supported blockchain ecosystems, which besides Solana include Ethereum, Polygon, Base, Arbitrum, and XRPL.
What Is New
The core of the expansion is timing flexibility: settlement becomes possible intraday and on weekends and holidays — that is, outside traditional banking hours. Settlement can occur on-chain. The initial rollout focuses, per the announcement, on the United States and Latin America, with broader expansion over the course of 2026. Named early participants include banks and payment firms such as Cross River, Lead Bank, CBW Bank, ARQ, and Nuvei.
Context for Solana
For Solana, inclusion means that one of the largest global payment networks recognizes the chain as a settlement rail — alongside established networks. It is an infrastructure signal, not a Solana-exclusive product.
