[Uniswap Fully Integrates Arc, Supporting cirBTC Trading and Pools Token Issuance] Odaily Planet Daily News: Uniswap announced that Uniswap v2, v3, v4, and UniswapX have integrated Circle's Layer 1 network Arc, designed for stablecoin-focused finance, and will serve as its preferred DEX starting from the day Arc launches on its mainnet. Users can exchange tokens, provide liquidity, and build applications on Arc via the Uniswap web app, wallet, and API. Circle's Bitcoin-backed stablecoin cirBTC, issued and custodied by Circle, is now live on Uniswap. Institutions can mint and redeem cirBTC through Circle Mint, while other users can trade cirBTC or provide liquidity for it. Pools has become the official token issuance platform for Arc, and tokens issued via Pools will enter Uniswap v4 liquidity pools paired with USDC, with liquidity permanently locked and no issuance platform fees charged. Project teams can choose to issue tokens immediately or conduct a 1-hour Crowd Launch. Developers can also integrate Arc trading functionality into applications or agents via the Uniswap API.
