Mantle v1.6.3 Fix After Nov 5 Reth Bug Keeps Assets Safe

Mantle Network continued to operate despite the presence of a state root bug in the op-reth upstream Reth client that was impacting Ethereum-compatible networks. The fix in op-reth mantle-v1.6.3 backports the upstream bug fix. Assets are safe, no user action is required, no database migration is required, and node operators were asked to upgrade. The incident was short and not visible to end users, and that means it might seem like it doesn’t matter. But it does: state roots are cryptographic commitments that are used to prove the validity of account balances and contract storage, and incorrect calculation of them can cause nodes to stall, return invalid proofs, or go offside the standard chain.
