    Since the first version of the Uniswap Protocol launched in 2018, onchain trading has exploded to support millions of users, hundreds of use cases, and $1.5 trillion of trading volume on Uniswap alone. To grow onchain trading and improve self-custody swapping, we're excited to announce a new permissionless, open source (GPL), Dutch auction-based protocol for trading across AMMs and other liquidity sources. Today, we're rolling out an opt-in beta for the protocol on the Uniswap Labs interface, available for Ethereum Mainnet and expanding to other chains and the Uniswap app in the future. You can review the code here and read the full whitepaper here. Over time, UniswapX will improve swapping in several ways: Better prices by aggregating liquidity sources Gas-free swapping Protection against MEV (Maximal Extractable Value) No cost for failed transactions And in the coming months, UniswapX will expand to gas-free cross-chain swaps. Next-level aggregation Onchain routing is an increasingly important and complex problem. Innovations in onchain trading have led to an explosion of liquidity pools. New fee tiers, new L2s, and more onchain protocols fragment liquidity. And we expect thousands more customized pool designs will be built on Uniswap v4, making routing even more challenging. But as liquidity sources grow, continuing to offer competitive prices requires manual integration and significant ongoing maintenance and effort. UniswapX aims to address this by outsourcing routing complexity to an open network of third-party fillers who then compete to fill swaps using onchain liquidity like AMM pools or their own private inventory. With UniswapX, swappers will be able to use the Uniswap interface without worrying whether they're getting the best price and transactions will always be transparently recorded and settled onchain. All orders are backstopped by the Uniswap Smart Order Router, which forces fillers to compete with Uniswap v1, v2, v3 and, once it launches, v4.
