Circle deploys $649M USDC and $7M EURC on Arc blockchain

Circle isn’t just issuing stablecoins anymore. It’s running the rails they move on.

The company behind USDC has deployed $649M in USDC and $7M in EURC on Arc, its own Layer 1 blockchain that launched its public mainnet on September 16, 2026. For a company that spent years being the “stablecoin issuer that works with every chain,” building its own chain is a sharp strategic pivot, one that CEO Jeremy Allaire has called potentially the most significant launch in Circle’s history.

What Arc actually does differently

Arc’s headline feature is deceptively simple: USDC is the native gas token. Transaction fees on Arc target roughly $0.01, denominated entirely in USDC.

The blockchain delivers sub-second deterministic finality, meaning transactions settle almost instantly with no ambiguity about whether they went through. Traditional blockchains often have probabilistic finality, where a transaction becomes “more confirmed” over time. Arc skips the uncertainty entirely.

Arc also launched with support for 22-plus fiat-linked stablecoins, not just USDC and EURC. The chain integrates Circle’s StableFX product, which enables atomic foreign exchange settlement between different stablecoin pairs.

The validator list reads like a Davos attendee roster

Circle announced the founding validator cohort on August 5, 2026, and it includes BlackRock, Visa, and Mastercard. The network launched with over 100 institutional participants spanning banks, asset managers, and DeFi protocols.

On the DeFi side, protocols like Aave and Morpho are already building on Arc, giving the chain immediate functional utility from day one.

The economics behind the chain

Circle executed a genesis mint of 10 billion ARC tokens. Prior to launch, a presale raised approximately $222M at a $3B fully diluted valuation. That presale price implies early buyers got ARC tokens at roughly $0.022 each.

The $649M USDC deployment on Arc represents a significant initial liquidity injection. Circle, being the issuer, can simply mint and deploy — the advantage of vertical integration.

The $7M EURC deployment is smaller but symbolically important. EURC, Circle’s euro-denominated stablecoin, has grown more slowly than USDC. Embedding it natively into Arc alongside the StableFX settlement system could accelerate euro-denominated DeFi activity.
