PANews reported on November 11 that according to The Block, blockchain infrastructure company Polymer Labs officially launched the real-time interoperability protocol Polymer Hub on the Ethereum mainnet, aiming to achieve seamless cross-chain communication between Ethereum Rollups. Polymer Hub initially supports the OP Stack ecosystem, including OP Mainnet, World Chain, and the Base network incubated by Coinbase, and plans to expand to other Ethereum Rollup ecosystems.

Polymer Hub is based on the IBC protocol developed by Cosmos, which reduces the overhead of cross-chain communication to achieve more efficient cross-chain speed and cost optimization. It uses a pre-confirmation mechanism and EigenDA technology to support data-intensive on-chain use cases, and provides reorganization protection to complete cross-chain transaction settlement at millisecond speeds to ensure transaction security.
