Uniswap (UNI) deploys full suite on X Layer, OKX’s zkEVM Layer-2 network, offering zero Uniswap Labs fees on swaps via Wallet, Web App, and Trading API.
Uniswap (UNI) has gone live on X Layer, OKX’s Ethereum Layer-2 network, marking the decentralized exchange’s latest multi-chain expansion. The January 15, 2026 deployment includes full support across Uniswap’s Protocol, Web App, Wallet, and Trading API—with zero Uniswap Labs fees on all swaps.
The integration positions Uniswap as X Layer’s “preferred DEX,” giving the exchange’s user base direct access to decentralized trading infrastructure from launch.
What X Layer Brings to the Table
X Layer is a zkEVM-based L2 built by OKX in collaboration with Polygon Labs. The network uses Polygon’s Chain Development Kit and zero-knowledge proofs to deliver lower transaction costs while maintaining Ethereum compatibility. For traders, this means cheaper swaps compared to mainnet without sacrificing security guarantees.
At launch, users can access core markets including USDG and other major stablecoins. Liquidity providers can immediately start earning fees on these pairs through Uniswap’s familiar interface.
Zero Fee Structure
The fee elimination applies across all Uniswap interfaces on X Layer. Retail users swapping through the Wallet or Web App pay no Uniswap Labs fees. Institutional players and developers using the Trading API get the same deal—direct protocol access without the typical interface markup.
This aggressive pricing suggests Uniswap is prioritizing market share on emerging L2s over immediate revenue capture. Teams looking to integrate can access X Layer liquidity through Uniswap’s Trading API hub.
Coming Soon: One-Click Transactions
Uniswap Labs plans to deploy 7702 delegation contracts to X Layer in the near term. These smart wallet contracts enable one-click transaction flows, eliminating the multiple approval steps that currently frustrate DeFi users. For builders on X Layer, this means smoother onboarding for their applications.
The deployment adds X Layer to Uniswap’s growing L2 roster alongside Ethereum mainnet, Base, and Unichain. As OKX pushes to bridge its centralized exchange users into DeFi, having Uniswap’s liquidity and brand recognition available from day one removes a significant friction point.
Users can start swapping immediately by selecting X Layer from the network dropdown in either the Uniswap Wallet or Web App.
