Visa added Arc, Base, Canton, Polygon, and Tempo to its stablecoin settlement pilot on Wednesday. The network now spans nine chains and is processing $7 billion in annualised live volume, up 50 per cent in a single quarter.
Visa added five blockchains to its stablecoin settlement pilot on Wednesday, taking the total to nine and pushing the network's annualised volume to $7 billion. The new chains are Arc, Base, Canton, Polygon, and Tempo. They join Avalanche, Ethereum, Solana, and Stellar, which Visa already supported. The $7 billion figure, the company is careful to point out, represents live transaction volume — not projections — and is up 50 per cent since the previous quarter.
What this means in practice is that an issuer or acquirer settling with Visa can now choose to do so in stablecoins, on any of nine networks, instead of waiting two to four days for funds to clear traditional banking rails. The economics are not subtle. Cross-border settlement that takes ninety-six hours through correspondent banks now takes seconds. The cost of moving a dollar across borders falls by orders of magnitude. Visa's role shifts from operator-of-rails to operator-of-rails-and-orchestrator-of-blockchains.
The five new additions tell you which way the company is betting. Tempo, Stripe and Paradigm's payments-focused Layer 1, launched earlier this month. Arc is Circle's own Layer 1, optimised for stablecoin issuance and tokenised dollar payments. Canton is the privacy-preserving institutional chain that runs much of the regulated DeFi infrastructure. Base is Coinbase's Layer 2 and the largest non-Ethereum L2 by daily active users. Polygon is the volume horse of the bunch, with deep merchant and consumer integration. Visa is now a design partner for Arc and a validator for both Tempo and Canton — institutional roles, not just integrations.
The numbers underneath the announcement are what matter for the broader stablecoin race. A $7 billion annualised run rate is small compared to Visa's overall settlement volume of roughly $14 trillion a year. But it has been growing 50 per cent quarter-on-quarter — and 50 per cent on 50 per cent compounds quickly. Tether settles roughly $200 billion in daily on-chain volume across all networks; USDC is closer to $30 billion. Visa is becoming a meaningful share of that flow on the regulated side, and that share is concentrating in chains where regulators have more visibility into who is sending what.
The competitive context is shifting fast. KuCoin put USDC on Mastercard's rails in Australia earlier this month, allowing users to spend stablecoins at any checkout. Western Union is preparing to launch a dollar stablecoin in May backed by 360,000 payout locations worldwide. Lightspark recently became a Visa principal member, allowing AI agents to spend Bitcoin-backed dollars at 175 million merchants. The legacy networks have decided that if they cannot beat stablecoin settlement, they will route it themselves and tax the spread.
There is a regulatory wrinkle worth watching. The Treasury, FinCEN, and OFAC published rules under the GENIUS Act earlier this month that effectively classify stablecoin issuers as banks for AML and sanctions purposes. Visa's new chains are not random in this light. Arc, Tempo, and Canton are explicitly designed for compliance use cases, with built-in privacy controls that can be selectively unwound for regulators. Polygon and Base are public, but both have institutional KYC and KYT layers in active production. Visa is not adding privacy coins.
Where this gets interesting is in the second-order effect. If banks can settle with Visa in stablecoins, and Visa accepts settlement on Base, then the smallest community bank in the United States can effectively use a public blockchain for cross-border movement without ever explicitly opting into 'crypto'. The bank does not need to know what Base is. It just needs to use Visa. The infrastructure becomes invisible — and that is what every legitimate payments product looks like at maturity, the opposite of how crypto sold itself for the better part of a decade.
The risks are not absent. Stablecoin settlement still depends on the issuer, and the issuer still depends on the underlying reserves. A USDC depeg, a Tether attestation problem, or a sanctions enforcement action against an offshore wallet can still propagate through Visa's network within hours. Visa's diversification across chains does nothing to diversify across stablecoins. That is a separate exposure the network has not addressed publicly.
$7 billion annualised is small. Compounding 50 per cent quarter on quarter, it is not small for long. Wednesday's announcement is the moment Visa stopped treating stablecoin settlement as an experiment and started treating it as a product line.
