Binance says $2.54bn frozen as it investigates suspected wallet hack
Binance has suspended deposits and withdrawals while it investigates a suspected breach of an Ethereum wallet, with stablecoin issuers and other firms freezing funds linked to the transfers.
Key points
- Binance says $2.54bn in assets has been verified as frozen, a figure it expects may rise as tracing continues.
- Tether froze more than $1.57bn in USDT and Circle more than $800m in USDC, according to their CEOs.
- Blockaid's Ido Ben-Natan says the preliminary assessment points to misuse of signing infrastructure rather than a leaked private key.
Binance is investigating a suspected hack of one of its Ethereum wallets, a case the exchange says has led to $2.54bn in assets being frozen. The exchange has suspended deposits and withdrawals while it runs security checks and works with law enforcement. It said it would publish a full post-mortem and cover all losses.
Concerns were first raised by blockchain researcher Spreek, who reported transfers from a Binance-linked wallet to a new address. Arkham Intelligence later tracked wallets labelled "binance-hacker-1029" holding about $5.84bn, a figure reflecting their holdings rather than a confirmed loss. Blockaid identified roughly $3.3bn in suspicious transfers across Ethereum, Arbitrum and Avalanche.
Signing key questions
Stablecoin issuers moved quickly. Tether's Paolo Ardoino said more than $1.57bn in USDT had been frozen, while Circle's Jeremy Allaire put its USDC freeze at more than $800m. Ripple is freezing RLUSD tied to the incident, and World Liberty Financial froze $27m in USD1 and $2m in WLFI. Binance co-founder Changpeng Zhao said he expected user funds to be fully covered.
Blockaid co-founder Ido Ben-Natan told Cointelegraph that the preliminary assessment pointed to misuse of signing infrastructure rather than a leaked private key. Aave froze markets run by its governance system as a precaution, saying its contracts were unaffected. Market makers Wintermute and GSR disclosed Binance exposure but expected no major disruption.
What to watch: Binance says withdrawals will resume once the security issue is resolved and it will publish a full post-mortem when the investigation is complete.
