UniswapX: The Future of Permissionless Trading

UniswapX, the latest evolution in onchain trading, is changing the game. This permissionless protocol enhances self-custody swapping while offering gas-free trades and superior liquidity.

A Leap Forward

On July 17, 2023, Uniswap Labs introduced UniswapX — a noncustodial Dutch auction-based trading protocol designed for the Virtual Machine. It aims to elevate the user experience by aggregating both onchain and offchain liquidity. This results in mitigated Maximal Extractable Value (MEV) issues through price improvement, gasless swaps, and cross-chain functionality.

Aggregating Liquidity Like Never Before

UniswapX leverages a Dutch auction model to pool liquidity from various sources. By outsourcing order routing complexity to third-party fillers, it ensures competitive pricing with transparent onchain transactions. The result? An optimized pricing mechanism without the hassle of manual integration or maintenance.

Say Goodbye to Gas Fees

One standout feature is gas-free swapping. Traders sign unique offchain orders submitted onchain by fillers who cover the gas costs. No direct gas fees are required; even failed transactions incur no costs for traders. Fillers can batch multiple orders into one transaction, optimizing costs for everyone involved.

Fighting Maximal Extractable Value (MEV)

MEV can often lead to unfavorable prices for traders. UniswapX mitigates this by returning MEV back to traders as price improvements and preventing sandwich attacks. By incentivizing private transaction relays during order routing, UniswapX makes swaps more efficient and fair.

Customizable Order Parameters

UniswapX offers flexibility in setting initial Dutch auction prices through an offchain Request For Quote (RFQ) system polling various fillers. This approach encourages fillers to propose their best prices, significantly enhancing the user experience.

Transparent Fee Structure

Governed by Uniswap Governance, a fee up to 0.05% can be levied on each swap’s output within UniswapX. Additionally, interfaces and wallets may impose additional uncapped fees.

Cross-Chain Swapping: The Next Frontier

Coming soon are cross-chain swapping capabilities that will allow seamless transactions across different networks — merging swap and bridge functionalities into a cohesive trading experience. Users will have more control over the assets received on destination chains, offering unprecedented flexibility.

With these groundbreaking features, UniswapX promises not just enhanced efficiency but a transformative effect on how we perceive decentralized trading.
