Unichain Transfers Production Operations to Optimism
Unichain plans to transfer its production operations to Optimism on October 29, expanding the managed-service model adopted by other chains such as Ink and Soneium. Unichain, a layer-2 chain for Ethereum, will transfer its production sequencing, public node access, monitoring, and incident response to Optimism. The move is part of Optimism's strategy to operate and improve the infrastructure of other brands' chains. Unichain's production operator changes while its deployed contracts and existing deployments remain in place. The announcement highlights Optimism's role as the operator of Ethereum-based chains for other brands, including Unichain, Ink, and Soneium. The transition preserves the chain ID, contracts, balances, and applications, including Uniswap v2, v3, and v4 deployments. The Optimism Foundation and OP Labs will support deployment, sequencer operations, node infrastructure, upgrades, monitoring, and incident response for Unichain.
