TREE NEWS update: Blockaid warned that a bug in reth can generate incorrect state proofs, and listed patched builds for reth, op-reth and Base. Gauntlet curtailed deposits and allocations in response to the issue. The warning concerns the Ethereum execution client and its OP Stack variants.
Blockaid warns reth bug can produce incorrect state proofs
The significance here lies less in the bug itself than in the response pattern: a security firm flagging a state-proof defect in a widely used execution client, and a risk manager curtailing deposits and allocations before any confirmed exploitation. State proofs underpin how many systems verify chain data, so a client that can produce incorrect ones touches infrastructure well beyond reth's own operators. What's worth watching is whether the patched builds see fast adoption across reth, op-reth and Base deployments, and whether other risk curators follow Gauntlet's lead in treating proof integrity as a gating concern rather than a routine patch.
