Uniswap Labs has rolled out full support for Ink, the Optimistic Rollup blockchain built by Kraken, across its entire product suite. That means traders and liquidity providers can now access Ink through the Uniswap web app, mobile wallet, and developer API, bringing another layer 2 network into the fold of the world’s largest decentralized exchange.
Uniswap V3 contracts were first deployed to Ink back in December 2024, following a governance request for comments. But getting smart contracts live on a chain and actually letting users interact with them through a polished frontend are two very different things. This update closes that gap.
What Ink brings to the table
Ink operates as an Optimistic Rollup within the Optimism Superchain framework, which means it inherits Ethereum’s security while processing transactions at a fraction of the cost. Its standout technical feature is 1-second block times, designed specifically to support the kind of rapid-fire trading that DeFi users have come to expect.
The chain carries chain ID 57073 and was purpose-built by Kraken for decentralized finance applications. With this full integration, Uniswap users on Ink now have access to v2, v3, and v4 protocol versions.
The long road from contracts to frontend
The timeline here tells a story about how blockchain integrations actually work in practice. The governance RFC and initial V3 deployment happened in December 2024. A GitHub issue from December 2025 flagged the need for proper frontend support before Ink could be considered fully integrated into the Uniswap platform.
Ink has been building momentum during that waiting period. The chain has accumulated hundreds of millions in total value locked across its DeFi ecosystem, with multiple active protocols contributing to a growing liquidity base.
Uniswap’s multichain chess game
This integration fits into a broader pattern that has defined Uniswap’s strategy over the past two years. The protocol has been methodically expanding across layer 2 networks, treating each new chain as an opportunity to capture trading volume that might otherwise flow to competitors.
Coinbase has Base. Kraken has Ink. Both are exchange-backed layer 2 networks competing for DeFi users, and both now have full Uniswap support.
The governance discussions that preceded this integration suggest the community is actively weighing these tradeoffs, balancing growth ambitions against the operational complexity of supporting an ever-expanding network of deployments heading into the final months of 2026.
