Blockaid: Reth client vulnerability could cause nodes to compute incorrect state roots

Blockaid disclosed a correctness bug in the Reth execution client and derivatives such as op-reth that can cause nodes to compute incorrect state roots for some blocks. The firm said the issue is not an exploit and no known fund losses have occurred. Gauntlet has already responded on some OP Stack chains by capping V1 vault deposits and pausing asset allocations. The incident matters because state-root mismatches can disrupt consensus and cross-client consistency even without direct theft. What to watch next is whether Reth and op-reth teams ship a fix and whether other OP Stack operators follow Gauntlet in restricting vault activity.
