POPA ReconCircle's Arc L1 hit mainnet. Behind it: 10 months of testnet.
Circle's Arc L1 hit mainnet. Behind it: 10 months of testnet. Since October 2025, Arc's testnet ran a full economy: 3.43M real wallets, 48.3M contracts deployed, 10.9M tokens created, 42.2M stablecoin transfers. The throughput held: 740.9M transactions across 62.4M blocks, 95.2% successful, at a $0.0038 average fee. On Arc, USDC isn't a token, it's the gas. 4.89M holders proved the model before mainnet.
