Uniswap Integrates Kraken-Built Layer 2 Network Across Entire Product Suite

Uniswap Labs has rolled out full support for Ink, the Optimistic Rollup blockchain built by Kraken. This means that traders and liquidity providers can now access Ink through Uniswap's web app, mobile wallet, and developer API.

This integration brings 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, but getting smart contracts live on a chain and allowing users to interact with them through a polished frontend are two very different things.

Ink operates as an Optimistic Rollup within the Optimism Superchain framework. This 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 rapid-fire trading that DeFi users have come to expect.
