Over the past 24 hours, news related to OP has centered on two areas. The Reth client experienced a state root computation error affecting some EVM chains; BNB Chain said its own impact was limited, and LayerZero has paused related cross-chain services. Immutable Chain, meanwhile, plans to migrate to OP Stack in mid-2027. After the migration is completed, block time will be shortened to 1 second, and native withdrawals may take about 7 days. At present, Immutable Chain's migration has not yet been implemented; the withdrawal duration above remains a planned arrangement, and the actual impact awaits further disclosure.

Odaily 星球日报 report: Immutable Chain plans to migrate to OP Stack in mid-2027, shortening block time from 2 seconds to 1 second.

Wu Blockchain has learned that Immutable announced plans to migrate Immutable Chain from a customized Geth to an Ethereum Rollup based on OP Stack in mid-2027, retaining the existing chain state and chain ID, with accounts, balances, contracts and authorizations carried over automatically, and the vast majority of users and developers needing to take no action.

According to a disclosure by security firm Blockaid, the Reth execution client and its derivative client op-reth have a state root computation error, affecting some EVM blockchains including multiple OP Stack chains; unpatched nodes may experience sync stalls or return incorrect state proofs (eth_getProof). The issue is a client correctness defect, not a known attack event, and no loss of funds has been found so far. Reth merged the fix code on November 3, with fixed versions including reth v2.10.0
