Visa, Nium Test Seven-Day Stablecoin Settlement in MAS Pilot

Stablecoins are moving beyond crypto trading into cross-border payments, treasury management and round-the-clock settlement, pushing card networks to define their role in onchain finance. Visa is positioning itself as an interoperability layer rather than a stablecoin issuer, linking fiat money, blockchains, wallets and its global merchant network. The strategy matters because preserving Visa’s network effects and service revenue will depend on remaining essential as payment infrastructure becomes programmable.

On July 28, 2026, Chief Executive Ryan McInerney told Visa’s fiscal third-quarter earnings call that the company had invested across blockchain, wallet and infrastructure layers, saying its role was “not to pick winners.” Visa joined Open Standard and on July 16 launched a platform initially supporting Open USD. It plans to connect Pismo for tokenized deposits and AI-driven commerce. Visa’s settlement pilot spans nine blockchains and was running at an annualized $7 billion, up 50% quarter on quarter.

Stablecoins are moving beyond crypto trading into payments, cross-border transfers and corporate treasury operations, prompting established networks to connect blockchain rails with conventional finance. Visa’s strategy is to shield banks and fintechs from the technical and compliance burden of running wallets and onchain workflows themselves. The stakes are considerable: Visa settles about $15 trillion annually and connects roughly 15,000 financial institutions with more than 200 million merchants, giving it a distribution network that could accelerate institutional use of digital dollars.

Visa on July 16, 2026, unveiled the Visa Stablecoin Platform, or VSP, a managed environment for minting, redeeming, holding and transferring stablecoins. The initial rollout centers on Open Standard’s newly introduced Open USD (OUSD) and interoperates with Visa’s existing stablecoin services, including Circle’s USDC and Paxos’ USDG. VSP also offers Wallet-as-a-Service, dual-approval controls, audit logs and transfer allow lists. Beta access is initially limited to selected clients. Visa already processes several billion dollars in stablecoin settlements and aims to fold those flows into existing payment, treasury and settlement systems.

Visa has tested stablecoin settlement using USDC on Ethereum since 2021, allowing issuers and acquirers to settle VisaNet obligations over blockchain networks. The model could overcome the constraints of banking hours and cross-border transfers, providing a supplementary settlement channel for traditional payment networks.

Visa said on April 29, 2026, that it had added Arc, Base, Canton, Polygon and Tempo. Together with Avalanche, Ethereum, Solana and Stellar, the additions brought the number of supported networks to nine. Its annualized settlement run rate reached $7 billion, up 50% quarter on quarter. On June 4, Visa also began testing privacy-controlled institutional settlement on Canton with Brale using the US dollar stablecoin SBC.
