Uniswap is bringing its entire trading stack to Arc, the Layer-1 blockchain Circle built to serve as a dedicated settlement layer for stablecoins. The deployment covers Uniswap's v4 automated market maker, liquidity pools, swap routing, and a full developer SDK and API, giving Arc a ready-made DeFi backbone from launch.
Integration timed to Arc's mainnet
The integration was first announced on June 15, 2026. Infrastructure goes live alongside Arc's public mainnet launch on September 16, 2026. For a chain built around stablecoin settlement, landing the protocol behind $4.4 trillion in all-time trading volume is a strong opening move.
What Arc is built for
Arc is Circle's attempt to design a blockchain around stablecoin transactions specifically, rather than treating stablecoins as just another token on a general-purpose chain. The network supports direct 1:1 swaps between major stablecoins including USDC, USDS, and DAI. Circle laid the groundwork in late 2025, launching a public testnet that October; over 100 partners took part, including Curve and Aave.
Hooks give developers custom pool control
Uniswap's v4 release introduced "hooks," a modular system that lets developers customize pool behavior without forking the protocol. With v4 hooks, developers on Arc can build pools with custom fee structures, oracle integrations, or compliance layers tailored to institutional settlement. The developer SDK and API deployment signals Uniswap is positioning itself as core infrastructure on Arc, not a standalone app sitting on top of the chain.
Uniswap and Curve now share the same chain
Landing Uniswap makes Arc's pitch to institutional capital more credible, since minimal slippage on stablecoin pairs is a requirement for handling large flows. Curve, which also joined Arc's testnet, has long been the dominant protocol for stablecoin swaps. Having both protocols building on the same stablecoin-native chain means they will either compete on spreads or find complementary niches within Arc's ecosystem.
With Uniswap's infrastructure live from launch, Arc avoids the cold-start liquidity problem that has held back other Layer-1 networks before they got off the ground.
