Uniswap turns on Ink across its web app, wallet and API

In Brief:

• Uniswap Labs switched on support for Ink, Kraken’s Optimism Superchain rollup, across its web app, wallet and API.
• Swaps and liquidity provision now run on Ink through Uniswap v2, v3 and v4, nearly two years after the first V3 contracts landed on the chain.
• Ink’s total value locked went from $7 million in October 2025 to close to $450 million by early 2026.

Uniswap Labs turned on Ink across its web app, wallet and API, turning Kraken’s layer 2 into a routable option for anyone already using those tools.

“Ink is live across Uniswap Web App, Wallet, and API,” Uniswap said in the post announcing the rollout. “Swap and provide liquidity on the L2 designed for global finance.”

Traders on Ink now reach v2, v3 and v4 from the same interfaces they use elsewhere. The API support carries further than the front end, since it means Ink quotes surface wherever that plumbing already runs.

The contracts were there. The button wasn’t.

Uniswap V3 contracts went live on Ink in December 2024, following a governance request for comments. The RFC noted all V3 contracts were already deployed and no further DAO action was needed.

What was missing was the interface. A GitHub issue filed in December 2025 flagged frontend support as the outstanding piece before Ink could count as fully integrated. This rollout closes it.

Ink runs as an optimistic rollup on the OP Stack inside Optimism’s Superchain, with chain ID 57073 and one-second block times. Kraken built it for DeFi and launched mainnet at the end of 2024. It was the first Superchain network other than Optimism Mainnet to ship permissionless fault proofs.

The money followed Tydro

Ink’s total value locked sat at $7 million in October 2025. By early 2026 it was near $450 million.

Two apps did most of that work. Nado, a perpetuals exchange, and Tydro, the chain’s money market, took combined app revenue from $500,000 in October to $5.77 million in January 2026.

Tydro is a white-label instance of Aave v3. The Aave DAO approved the deployment with roughly 99.8% support, and it launched in October 2025 with INK incentives and a narrow asset list.

Kraken then wired it into its own product. Kraken DeFi Earn launched in January 2026, paying yield on USDC through Tydro and Aave on the back end across three vault options administered by Veda. Deposits have passed $200 million.

Kraken’s answer to Base

The Optimism Foundation granted Kraken 25 million OP, worth about $42.5 million, to build the chain. Five million covered engineering. The other 20 million was contingent on transaction milestones.

Kraken CEO David Ripley framed Ink at launch as a way to give a wider audience access to DeFi. The exchange counts more than 10 million users.

The INK token carries a fixed supply of 1 billion and doesn’t govern the rollup. Governance and revenue sharing stay with the Optimism Collective, and holders instead steer incentives toward protocols deploying on Ink.

Uniswap now runs on 48 chains, with v4 deployed on 18 mainnets including Ink, Unichain, Base, Arbitrum One, Soneium, Monad, MegaETH, Tempo and Robinhood Chain.

And developers weren’t waiting on the frontend. Uniswap’s hook registry merged NFTXV4Hook on Ink on Sept. 10 and approved DuckHookV4 on Sept. 6, days before the app itself acknowledged the chain.
