In Brief:
- Support for Ink — the Optimism Superchain rollup built by Kraken — is now switched on inside Uniswap Labs’ web app, wallet and API.
- Traders can swap and supply liquidity on Ink through Uniswap v2, v3 and v4, arriving almost two years after the chain’s first V3 contracts went up.
- Value locked on Ink climbed from $7 million in October 2025 to roughly $450 million by early 2026.
By enabling Ink in its web app, wallet and API, Uniswap Labs has made Kraken’s layer 2 a routable destination for everyone already working inside those tools.
“Ink is live across Uniswap Web App, Wallet, and API,” Uniswap wrote in the post announcing the rollout. “Swap and provide liquidity on the L2 designed for global finance.”

Anyone trading on Ink can now hit v2, v3 and v4 through the same interfaces they already use on other networks. The API piece stretches beyond the front end, because it puts Ink quotes anywhere that plumbing is already wired in.
Deployed contracts, no button to press
Ink received live Uniswap V3 contracts back in December 2024, after a governance request for comments. That RFC pointed out that every V3 contract had already been deployed and that the DAO had nothing left to do.
The gap was the interface itself. A GitHub issue opened in December 2025 identified frontend support as the last missing piece standing between Ink and a full integration. That box is now ticked.
Built as an optimistic rollup on the OP Stack within Optimism’s Superchain, Ink uses chain ID 57073 and produces blocks every second. Kraken designed it for DeFi and shipped mainnet in late 2024. No Superchain network besides Optimism Mainnet had shipped permissionless fault proofs before it did.
Tydro pulled the deposits in
October 2025 saw Ink holding $7 million in total value locked. That figure was approaching $450 million by early 2026.
Most of the growth traces back to two applications. Combined app revenue from the perpetuals venue Nado and Tydro, the network’s money market, rose from $500,000 in October to $5.77 million in January 2026.
Tydro itself is a white-label deployment of Aave v3. Backing from the Aave DAO came in at roughly 99.8%, and the market went live in October 2025 with a short asset list and INK incentives attached.
Kraken proceeded to plug it into its own lineup. Arriving in January 2026, Kraken DeFi Earn pays out USDC yield routed through Tydro and Aave underneath, offered via three Veda-administered vault options. More than $200 million has been deposited.
Kraken’s counter to Base
Kraken received 25 million OP — around $42.5 million — from the Optimism Foundation to get the chain built. Engineering work accounted for five million of that, while the remaining 20 million hinged on hitting transaction milestones.
At launch, Kraken CEO David Ripley described Ink as a route to opening DeFi up to a broader audience. The exchange has upwards of 10 million users.
INK’s supply is capped at 1 billion, and the token has no say over the rollup. The Optimism Collective retains governance and revenue sharing, leaving holders to direct incentives toward protocols that deploy on Ink.
Across its footprint, Uniswap is now on 48 chains, with v4 live on 18 mainnets — Ink among them, alongside Unichain, Base, Arbitrum One, Soneium, Monad, MegaETH, Tempo and Robinhood Chain.
Builders, for their part, had already moved ahead of the interface. NFTXV4Hook was merged on Ink in Uniswap’s hook registry on Sept. 10, and DuckHookV4 won approval on Sept. 6 — both before the app itself recognized the chain.
