Uniswap is Live on Arc

#Protocols

#Products

Uniswap v2, v3, v4 and UniswapX are live on Arc, the Layer 1 built by Circle for stablecoin finance. Uniswap is Arc's preferred DEX from day one, with support on the Uniswap Web App, Wallet, and API. Pools comes to Arc as an official launchpad, and cirBTC trades on Uniswap on Arc from launch.

Arc on Uniswap

Most onchain trades settle in stablecoins, and a growing share of payments between traditional finance and DeFi run on them. Uniswap has processed $2.7 trillion in stablecoin volume since 2020, including roughly $2 trillion in USDC. In the second quarter of 2026 alone, $43 billion in stablecoin-to-stablecoin swaps settled on the protocol, more than the next three onchain venues combined.

That market is what Arc was built for. The network's fees are paid in stablecoins, starting with USDC, and blocks finalize in under a second. Founding validators include BlackRock, DTCC, Mastercard, and Visa. Starting today, anyone can swap, provide liquidity, launch and build on Arc with the same Uniswap products millions of people already use and trust.

Where cirBTC trades

cirBTC is available on Uniswap on Arc at launch. It's bitcoin issued by Circle, backed by BTC in Circle's custody. Institutions can mint and redeem it through Circle Mint. Anyone can swap it or provide liquidity for it on Uniswap.

Pools comes to Arc

Pools joins Arc as an official launchpad from day one. Launch a token, discover new ones, and trade them end to end at pools.xyz.

Every token launches into a Uniswap v4 pool paired with USDC. Liquidity is permanently locked, and there are no launchpad fees. Creators can launch instantly, or run a one-hour Crowd Launch.

Developers and agents

For developers, Uniswap API makes it easy to add swaps on Arc to your app or agent.

  1. Go to the developer dashboard to create an account and get an API key
  2. Follow the Quickstart Guide to get started, setting the chain ID 5042 for Arc
