Visa expanded its global stablecoin settlement pilot to nine total blockchain networks Wednesday, as the payment giant's blockchain infrastructure reaches a $7 billion annualized run rate with 50% quarterly growth.

The newly added networks—Arc, Base, Canton, Polygon, and Tempo—each serve distinct settlement needs, according to Visa's announcement. Polygon and the Coinbase-incubated Base are both Ethereum scaling networks, while Circle’s Arc and Stripe’s Tempo network are layer-1 chains focused on stablecoins and payments, and Canton offers configurable privacy options for institutions.

These additions complement Visa's existing support for Ethereum, Solana, Avalanche, and Stellar, creating a comprehensive multi-chain settlement layer.

The pilot's rapid growth reflects accelerating institutional adoption of blockchain payment rails. Visa’s stablecoin settlement volume jumped from approximately $4.7 billion to $7 billion on an annualized basis in just one quarter, the financial giant said.

Visa's broader stablecoin ecosystem extends beyond settlement infrastructure. The company operates more than 130 stablecoin-linked card programs spanning more than 50 countries, bridging digital assets with traditional payment networks.

“Our partners are building in a multi-chain world, and they expect their options to reflect that reality,” said Visa Global Head of Growth Products and Strategic Partnerships Rubail Birwadker, in a statement. “Expanding our stablecoin settlement pilot program to more blockchains means our partners can choose the networks that best fit their needs, while relying on Visa to provide a common settlement layer across all of them.”

Arc, Tempo, and Canton are newer entrants to the blockchain industry, and Visa has already offered support to all three. Visa is a design partner for Arc, and more recently became a validator for both Tempo and Canton.
