Ink, the Ethereum layer 2 incubated by Kraken, moved to OP Enterprise Fully Managed on June 24, handing OP Labs operational control of its production stack under a multi-year agreement, The Block reported. Under the deal, Optimism runs Ink's sequencer, batcher, proposer, and supporting infrastructure; the Ink Foundation shifts its focus to ecosystem growth and new financial products.
"By working together, the Ink Foundation can focus on growing the ecosystem while Optimism focuses on operating and improving the network," Optimism CEO Jing Wang said. Ink Foundation Head of Strategy Zach Le framed the move in operational terms: "The next phase of onchain finance demands a chain operated by those with the technical depth to prioritize reliability and security."
Ink is also named a design partner for OP Enterprise, contributing to features including programmable block building, one-day Ethereum withdrawals, and sequencer-level compliance tools.
Bitpanda's Vision Chain, deployed earlier in 2026, was the first network on OP Enterprise Fully Managed; Ink is the second. The Ink Foundation is a separate entity from Kraken's exchange business, though Kraken incubated the chain. Ink launched its mainnet in December 2024 and processed more than one million transactions in its first 24 hours; applications on the network now generate close to $40 million in annual revenue.
OP Stack now underlies Base, Worldchain, Ink, and others. The Ink deal extends OP Labs' role from framework provider to managed operator: the second time Optimism has taken on that responsibility and the first for a chain backed by a major US exchange.
