Key highlights:
- $88M stolen from Balancer in a cross-chain hack that’s still unfolding
 - Third major exploit in months raises serious DeFi security questions
 - Investigators track suspicious transfers as Balancer stays silent
 
The DeFi protocol Balancer has suffered a massive exploit, with hackers draining $88 million in assets from its storage.
Cybersecurity firm PeckShield reported that the attack is still ongoing, spreading across several blockchains where Balancer is deployed — one of the largest multi-chain DeFi hacks of 2025 so far.

Scale of the attack and how it happened
Data from Etherscan revealed large suspicious transfers from a Balancer address to a newly created wallet. According to analytics platform Nansen, around $70.9 million in assets moved in just three transactions:
- 6,850 StakeWise Staked ETH (OSETH)
 - 6,590 Wrapped Ethereum (WETH) — about $24.5 million
 - 4,260 Lido wstETH (wSTETH)
 
Blockchain security firm Cyvers estimated the total at $84 million, while PeckShield later confirmed losses reaching $88 million.
These cross-chain movements point to a coordinated exploit targeting multiple Balancer liquidity pools, suggesting an advanced and well-planned attack.
A pattern of vulnerabilities raises red flags
This breach adds to a string of security failures for Balancer.
In Sep 2023, hackers launched a DNS attack on its front-end, redirecting users to a phishing site that drained about $238,000. Blockchain detective ZachXBT first reported the incident.

Just a month earlier, in August, Balancer lost nearly $1 million in a stablecoin exploit — barely a week after the team disclosed a “critical vulnerability” in certain liquidity pools.
These recurring issues have shaken community confidence and sparked calls for a full security overhaul across DeFi protocols.
About the balancer protocol
Balancer is a decentralized exchange (DEX) and automated market maker (AMM) built on Ethereum.
It allows users to trade tokens and provide liquidity through self-balancing pools that automatically adjust token ratios. The platform, launched in 2020, holds over $350 million in total value locked (TVL) on Ethereum alone.
So far, the Balancer team has not publicly confirmed the exploit, though the suspicious outflows strongly indicate a breach.
With three major attacks in under six months, investors are questioning the protocol’s resilience and whether DeFi security standards can keep pace with increasingly sophisticated threats.
