Flow Foundation: Release no-rollback recovery plan, over 99.9% of accounts unaffected

TechFlow news, December 29: The Flow Foundation has proposed a new recovery plan for the security vulnerability that occurred on December 27. Developed in consultation with bridge operators, exchanges, and infrastructure partners, the key features of this plan are as follows:

• No network rollback: There will be no blockchain reorganization or requirement for partners to replay transactions
• Preservation of legitimate user activity: Over 99.9% of accounts are unaffected and will resume full normal operation after restart
• Precise remediation: Temporary restrictions applied only to accounts that received fraudulent tokens
• Transparent handling: Fraudulent tokens will be verifiably burned via on-chain transactions audited by an independent blockchain forensics firm

The recovery plan will be implemented in four phases:

1. Cadence environment restored and brought back online; EVM remains read-only
2. Cadence environment repair completed (approximately 24–48 hours)
3. EVM environment repaired and re-enabled
4. Bridges/exchanges resume operations after verifying network stability

The attack resulted in the transfer of approximately $3.9 million in assets. The Flow Foundation is currently working closely with validators and the community to ensure secure restoration of the network.
