Circle, Issuer of USDC, Starts Testing Arc Blockchain With Big Institutions Onboard

Why It Matters

The involvement of leading banks, payment networks and cloud providers underscores growing institutional confidence in blockchain‑based settlement, potentially accelerating mainstream adoption of stablecoins and reshaping the competitive landscape for financial infrastructure.

Summary

Circle, the issuer of the USDC stablecoin, has launched a public testnet of its Arc blockchain and is already engaging major financial and technology firms such as BlackRock, HSBC, Visa, Amazon Web Services and AI startup Anthropic. The testnet’s early traction shows strong institutional interest in a public, permissioned network designed for stablecoin settlement and broader financial applications. Circle’s collaboration with these heavyweight participants aims to validate Arc’s scalability, compliance and integration capabilities ahead of a wider rollout. The initiative signals a push to embed crypto‑native infrastructure within traditional finance ecosystems.
