@Uniswap has confirmed it will be live on @arc from the moment Circle's new blockchain opens to the public. Circle has set September 16, 2026 for the public mainnet launch of Arc, and @Uniswap is among the DeFi protocols committing to be ready from the first day. The move brings Uniswap v4, liquidity pools, swap routing, and developer tools to Arc as the network prepares for its public mainnet launch.
Arc is currently in private mainnet with more than 100 ecosystem and institutional builders and is on track for a public mainnet launch on September 16, 2026.Circle first announced the network on August 12, 2025, launched its public testnet on October 28, 2025, and during the testnet phase the network processed over 244 million transactions.
BlackRock, DTCC, Galaxy, Global Payments, ICE, Mastercard, MoneyGram, SBI Group, Standard Chartered, Sumitomo Corporation and Visa will secure the network alongside Circle. Circle announced the founding cohort on August 5, 2026. Speaking on the company's Q2 earnings call, the Circle CEO called the lineup "a cohort of network validators no other network can match."
BlackRock is expected to deploy BUIDL, its tokenized money market fund, on Arc, while DTCC will enable tokenization of assets it custodies, though not until the second half of 2027.
Arc is an open Layer-1 blockchain operated by a permissioned validator set, and gas on the network is payable in $USDC.Arc is set to launch with day-one applications spanning DeFi protocols such as Aave, Morpho, and Uniswap, as well as stablecoin payments providers and wallet infrastructure. Circle is also working with DTCC to allow tokenization of DTC-custodied assets on Arc, with the connection letting market participants use third-party applications for stablecoin-native settlement against DTC-tokenized assets.
