According to blockchain analytics firm Nansen, decentralized finance protocol Balancer appears to have been the target of a significant security incident after roughly $70.9 million in assets were transferred to a newly created wallet.
The alert, circulated by Nansen, identified the moved assets as approximately 6,850 osETH, 6,590 WETH, and 4,260 wstETH tokens broadly used in Ethereum staking and wrapped-ETH ecosystems.
At publication, Balancer’s official channels had not issued a statement confirming or denying the report, leaving the claim unverified by the protocol’s governance or core development teams.
Nansen alerts are closely watched across crypto markets, but independent on-chain verification of contract addresses, timestamps, and pool balances is required to determine whether the transfers reflect a malicious exploit, rug pull, internal migration, or administrative rebalancing.
If confirmed as a theft or exploit, the outflow would represent one of the larger single-incident movements associated with Balancer liquidity pools in recent months, with potential market consequences.Â
Large transfers of staked and wrapped ETH derivatives can exert downward pressure on related token prices, reduce liquidity available on decentralized exchanges, and force other DeFi protocols that rely on Balancer for routing or liquidity to react quickly to contain systemic risk.
Security researchers and market participants urged caution. “Analytics alerts are early warnings, not final verdicts,” said one independent auditor, who requested anonymity. “On-chain tracing and protocol logs are essential before drawing conclusions.”
Meanwhile, affected liquidity providers and users were advised to monitor Balancer’s verified communication channels, temporarily avoid interacting with suspicious pools, and consider revoking smart-contract approvals if they suspect exposure.
Several exchanges and custodial services often pause related addresses or markets during emerging incidents; whether any third parties have taken protective measures in this case has not been independently confirmed. Journalists and analysts are attempting to contact both Nansen and Balancer for clarification.
This outlet will continue to track developments and update readers as more verifiable on-chain analysis or an official Balancer response becomes available.
