deBridge founder Alex Smirnov urged Flow validators to stop processing transactions until the Flow Foundation issues a remediation plan after Flow rolled back the chain following a $3.9 million theft on Dec. 27. The attacker exploited an execution-layer flaw and moved funds off-chain via cross-chain bridges; deBridge warned the rollback could create doubled balances for users who bridged out during the rollback window. Flow has been stuck at block height 137,385,824 since 11:24pm UTC; a restart was said to be expected in 4–6 hours. The incident and rollback pushed the FLOW token down about 42%; Flow metrics cited roughly $85.5M TVL and a ~$167.3M market cap.

A $3.9M theft and an execution-layer exploit led to a chain rollback and a halt at a specific block height; validators were urged to stop processing transactions, deBridge warned of doubled balances for bridged users, and FLOW fell ~42%. These are concrete, market-moving facts reported in the summary.
