UniswapX: The Future of Onchain Trading

Since its launch in 2018, Uniswap has revolutionized onchain trading, supporting millions of users and $1.5 trillion in trading volume. Now, Uniswap is introducing UniswapX, a new permissionless, open source (GPL) Dutch auction-based protocol for trading across AMMs and liquidity sources.

Opt-In Beta Now Live!

UniswapX is now available in opt-in beta on the Uniswap Labs interface for Ethereum Mainnet. In the future, it will expand to other chains and the Uniswap Wallet. Check out the code here and read the full whitepaper for a deep dive into the technology.

How UniswapX Enhances Swapping:

🔹 Better Prices: UniswapX aggregates liquidity sources to offer more competitive prices for traders.

🔹 Gas-Free Swapping: Swappers sign an offchain order, and fillers submit it onchain, paying the gas fees on the swappers' behalf. No gas fees for users!

🔹 MEV Protection: UniswapX returns MEV to swappers, preventing worse prices caused by arbitrage.

Better Prices:

Onchain routing is complex, with an explosion of liquidity pools and customized pool designs. UniswapX solves this by outsourcing routing to third-party fillers, who compete using onchain liquidity like AMM pools or private inventory.

With UniswapX, swappers can use the Uniswap interface without worrying about getting the best price. All transactions are recorded and settled onchain, ensuring transparency and efficiency.

Gas-Free and Fail-Safe Swapping:

Thanks to UniswapX, swappers don't need a chain's native network token (e.g., ETH, MATIC) to trade and won't be charged for failed transactions. Fillers price the gas fee into the swap price and can lower costs by batching multiple orders.

Protecting Against MEV:

MEV is a pressing issue in onchain swapping. UniswapX returns MEV to swappers through improved prices and protects users from explicit extractive forms of MEV. Orders executed with fillers’ inventory cannot be sandwiched.

Cross-Chain UniswapX on the Horizon:

UniswapX is getting even better! Later this year, we'll launch a cross-chain version, combining swapping and bridging into one seamless action. Swappers can swap between chains in seconds, choosing their desired assets on the destination chain.

UniswapX is an immutable, permissionless smart contract, free from modification or pausing by Uniswap Labs or anyone else. Swappers maintain full custody of their funds, ensuring security and trust.
