Binance said about $3 billion had been frozen on-chain, that it would cover all losses using its SAFU fund and company funds, and that user funds were safe. It also said it found no evidence of a wallet private key leak.
The company said deposits and withdrawals were temporarily suspended during security checks, and that it had revoked the affected address authorization. Binance said it was working with law enforcement and blockchain partners and would publish a technical post-mortem after its investigation.
