TLDR
Visa is expanding its USDC stablecoin settlement rails by adding five new blockchains, making its pilot a nine-network, multi-chain infrastructure with a roughly 7 billion dollar annualized run rate.
- Visa added Arc, Base, Canton, Polygon, and Tempo to a stablecoin settlement program that already supported Avalanche, Ethereum, Solana, and Stellar, bringing the total to nine networks.
- The program now settles around 7 billion dollars annually in stablecoins, up about 50 percent quarter over quarter, across more than 130 card programs in over 50 countries.
- This is back end infrastructure, not a retail token launch, so the impact for specific chains depends on whether real settlement volume and stablecoin liquidity actually grow on those networks.
Deep Dive
1. What Visa Actually Changed
Multiple reports confirm that Visa has added Arc, Base, Canton, Polygon, and Tempo to its global stablecoin settlement pilot, alongside existing support for Avalanche, Ethereum, Solana, and Stellar, for a total of nine blockchains.
According to Visa-focused coverage, the expansion is framed as part of a multi-chain strategy where partners can choose the network that best fits their needs while Visa provides a common settlement layer for all of them.
Each added chain targets a different segment: Polygon and Base as high throughput, low fee scaling networks; Arc and Tempo as stablecoin and payments focused layer 1s; and Canton as a permissioned, privacy configurable network for regulated institutions.
For crypto users, this is a signal that large payment players see value in multiple chains, not just Ethereum, for real settlement workflows in stablecoins like USDC.
2. Scale And Adoption So Far
Visa says the stablecoin settlement pilot has reached about a 7 billion dollar annualized run rate, roughly 50 percent higher than the previous quarter, as highlighted in several reports on the expansion to nine blockchains.
The program reportedly supports over 130 stablecoin linked card programs in more than 50 countries, and has been piloted across Latin America, Europe, Asia Pacific, Central and Eastern Europe, the Middle East, and Africa.
This is still tiny compared with Visas overall fiat settlement volumes, but it shows that stablecoins have moved from proof of concept into operational use for certain issuer and acquirer relationships.
Stablecoin rails are becoming real infrastructure in traditional payments, though they remain a small, experimental slice of Visas total business.
3. Implications For Chains And Stablecoins
For networks like Polygon and Base, inclusion in Visas program is a strong institutional signal that their low fee, high throughput designs meet compliance and reliability standards for large scale settlement.
For Arc, Tempo, and Canton, Visas support could bootstrap institutional interest, since they are newer chains positioned specifically around stablecoin payments, programmable commerce, or regulated capital markets.
For the stablecoin ecosystem, this reinforces USDC and similar assets as serious tools for cross border and after hours settlement, while also highlighting that real benefits depend on regulatory clarity and on whether banks and fintechs actually route volume through these new rails.
The main opportunity is for chains and stablecoins that can capture real settlement volume and fees; the main risk is that regulatory shifts or technical issues slow institutional adoption just as pilots scale up.
Conclusion
Visas decision to add five new blockchains to its stablecoin settlement program links mainstream payments more tightly to onchain infrastructure and confirms a multi-chain future for stablecoin rails.
The immediate impact is infrastructural rather than speculative, but if issuers and acquirers begin routing meaningful volume over these networks, it could deepen liquidity and onchain activity on chains like Polygon, Base, Arc, Tempo, and Canton.
