Circle's Arc Mainnet Goes Live
BanklessDavid Christopher
The USDC issuer just launched its own Layer 1, arriving to an arena already fielded by Tether and Stripe. To date, you might fairly describe Circle's business model as staying neutral. In other words, USDC is distributed wherever users already are (e.g. Ethereum, Solana, Base, Tron, etc.), and then chains compete for its liquidity. Alas, that singular era is seemingly over. Today, Circle officially flipped the greenlight switch on Arc, its own Layer 1 blockchain. Now the stablecoin giant will be building its own blockspace instead of only renting it. If you haven’t been following the Arc story, Circle first announced plans for the EVM-compatible L1 back in August 2025. The chain’s testnet rolled out in October 2025, and nearly one year later mainnet has finally arrived.
