Flow's rollback chain has sparked controversy, with ecosystem partners claiming they have not received coordination.

Alex Smirnov, co-founder of deBridge, stated that Flow's decision to roll back the blockchain without sufficient coordination with key ecosystem partners such as bridges and exchanges could pose a greater systemic risk than the original vulnerability. As one of Flow's main cross-chain bridges, deBridge received no prior communication. The rollback could lead to issues such as duplicate assets for cross-chain users and inability to reconcile deposits. He urged Flow validators to suspend verification until a remedial plan is clearly defined and ecosystem coordination is completed, and questioned the rollback decision-making process and the attribution of responsibility.
