Circle Internet Group (CRCL) shares fell 7.13% to $80.15 as the company launched Arc on public mainnet. The stock erased earlier gains after trading near $86.30 before a sharp mid-morning decline. Meanwhile, Arc entered production with major financial institutions, exchanges, wallets, and DeFi platforms connected from launch.
Circle designed Arc as a Layer 1 network for payments, trading, lending, asset issuance, and cross-border settlement. The network uses USDC for transaction fees, which removes the need for a separate volatile gas token. It also provides sub-second finality and supports post-quantum signatures for added security.
Arc also supports tokenized assets, stablecoins, and programmable foreign exchange through Circle StableFX. Circle integrated its payments network directly into Arc for near-real-time cross-border transfers. The system also supports confidential transactions, although network-wide privacy features remain under development.
The company built Arc for human users and automated economic agents using programmable payment tools. Circle said USDC already dominates transaction volume across agent-driven payment activity using the x402 standard. Arc now extends that approach with controlled wallets, small payments, and delegated onchain tasks.
Circle launched Arc with a validator group that includes BlackRock, DTCC, Galaxy, ICE, Mastercard, and MoneyGram. Standard Chartered, Sumitomo, Visa, SBI Group, and Worldpay also joined the phased validator rollout. These companies will help operate the network while supporting institutional settlement and tokenized finance.
Arc also launched with more than 100 applications and over 100 institutional and ecosystem builders. Banks including BNY, HSBC, State Street, and Societe Generale gained access to the network. Asset managers and issuers include BlackRock, Bitwise, Janus Henderson, ProShares, Maple, and Matrixdock.
Payments firms and exchanges expanded Arc’s reach across global trading and settlement channels. Binance, Coinbase, Kraken, OKX, Bybit, Bitso, and Upbit joined the exchange group. Visa, Mastercard, JCB, MoneyGram, Thunes, and Global Payments supported stablecoin settlement and broader payment connectivity.
Arc launched with trading protocols including Uniswap, Aero, 1inch, Robinhood, Pump.fun, and LI.FI. Aave and Morpho also brought lending markets to the network from launch. Custody support came from Anchorage, BitGo, Copper, Fireblocks, Ceffu, and Zodia Custody.
The wallet lineup includes MetaMask, Phantom, Ledger, Rainbow, Trust Wallet, and several exchange-linked wallets. Infrastructure providers include Alchemy, Chainlink, Blockdaemon, Figment, Kaleido, and QuickNode. These services give developers access to familiar tools while keeping Arc compatible with Ethereum software.
Circle said Arc’s developer community includes more than 75,000 active members and 10,000 program ambassadors. Developers have built more than 1,200 projects, while the testnet processed over 700 million transactions. Circle also released Arc Studio and Arc App Kits to simplify application development and deployment.
