Mastercard Brings Always-On Stablecoin Settlement to Solana With USDC, PYUSD, and RLUSD

Mastercard is expanding its global payments network to settle card transactions using regulated stablecoins across eight blockchain networks, including Solana, the company announced Tuesday. The move enables issuers and acquirers to settle outside traditional banking hours (nights, weekends, and holidays) with intraday finality rather than waiting for the next business-day settlement window.

Circle USDC$1.0000.0% Circle's USDC USDC is already live in early on-chain settlement flows in select markets. Alongside it, Paxos USDP$0.980+0.2% Paxos-issued stablecoins including [[TOKEN:2b1kV6DkPAnxd5ixfnxCpjxmKwqjjaYmCZfHsFu24GXo]] PYUSD, [[TOKEN:2u1tszSeqZ3qBWF3uNGPFc8TzMk2tdiwknnRMWGWjGWH]] USDG, and USDP, Ripple's RLUSD, and SoFi's SoFiUSD round out the initial stablecoin roster. Supported networks span Solana, Ethereum, Polygon, Base, Arbitrum, Canton, Tempo, and the XRP Ledger.

"The next phase of stablecoin adoption is about real-world utility, especially in settlement, where timing and liquidity matter most," said Raj Dhamodharan, Mastercard's executive vice president of Blockchain and Digital Assets. "By introducing intraday and weekend settlement options across our global network, we're expanding how partners manage liquidity and operate in an always-on digital economy while maintaining the trust, resilience and safeguards they expect from Mastercard."

How Mastercard's Stablecoin Settlement Works on Solana

Under the existing Mastercard model, issuers and acquirers settle in fiat across national clearing systems that pause on weekends and public holidays. A cardholder transaction processed on a Friday evening may not fully settle until Monday, creating overnight liquidity exposure for the acquiring bank.

The stablecoin pathway routes the same settlement obligation through a blockchain network. Once Mastercard designates a regulated stablecoin as the settlement instrument, the issuer transfers the stablecoin amount to Mastercard, which forwards it to the acquirer, all on-chain, with the finality timeline determined by the chosen network. On Solana, where block times run under a second and finality is sub-second at the validator level, the settlement can complete in moments rather than days.

The expansion is designed as an additive layer. Partners can continue settling in fiat alongside stablecoins, giving issuers and acquirers optionality as they build comfort with on-chain rails.

First Partners in the US and Latin America

ARQ (formerly DolarApp), CBW Bank, Cross River, Lead Bank, and Nuvei are named as the first wave of institutions expected to support stablecoin settlement in the United States and Latin America, with broader rollout planned through 2026.

The partner quotes reflect an alignment between infrastructure builders who have already been operating with stablecoins and a global card network that can scale their reach. "Stablecoins have been core to our infrastructure from day one," said Álvaro Correa, co-founder and COO of ARQ. "Partnering with Mastercard to enable on-chain settlement is a major step toward building the financial infrastructure we envision for the Americas."

Cross River, which has been running stablecoin-adjacent settlement infrastructure, pointed to Mastercard's move as network-level validation. "Mastercard's decision to bring on-chain settlement to its global network validates what we've been building toward: a future where digital asset rails operate seamlessly alongside traditional payments infrastructure," said Luca Cosentino, head of on-chain finance at Cross River.

Context: Mastercard's Stablecoin Buildup

Tuesday's announcement follows a sequence of moves Mastercard has made to position itself inside stablecoin infrastructure. In March 2026, the company agreed to acquire enterprise stablecoin infrastructure provider BVNK for up to $1.8 billion. In May, Mastercard secured a BitLicense from the New York State Department of Financial Services, establishing the compliance framework to clear tokenized deposits and payment stablecoins within the state. It also granted a Principal Membership to stablecoin card issuer Rain.

The expansion also places Mastercard alongside Visa, which has been running its own stablecoin-linked settlement pilots across multiple blockchains. Total dollar-pegged stablecoin supply is approaching $300 billion, per The Block's data dashboard, with USDT accounting for roughly $188 billion and USDC ranking second at approximately $76 billion.

For Solana specifically, the Mastercard inclusion adds another institutional credentialing point to a network that has been accumulating traditional finance validation in 2026. Galaxy Digital's Q1 2026 research report found Solana's stablecoin supply diversified substantially in the quarter, with USDT USDT growing 34% while newer entrants gained ground, and the network holding 31% of decentralized exchange volume for the fifth consecutive quarter. Being named alongside Ethereum and Arbitrum in Mastercard's global settlement infrastructure carries weight beyond any single transaction volume figure.

Mastercard said it plans to expand the program to additional regions, partners, and regulated stablecoins over time, subject to local regulation.
