Bitcoin News Today: DeFi's Trust Crisis: $110M Balancer Exploit Highlights Systemic Vulnerabilities

Balancer's $110 Million DeFi Pool Exploit Sparks Market Turmoil and Emergency Responses

The incident was first flagged by a Cryptoticker report.

A massive exploit targeting Balancer's decentralized finance (DeFi) pools has drained over $110 million in assets, marking one of the largest DeFi security breaches of 2025. The attack, initially reported to have siphoned $70–88 million, escalated as the attacker continued siphoning funds across multiple chains, with total losses now exceeding $128 million, according to PeckShield and blockchain analytics firm Nansen, as reported by Coinpedia. The breach impacted Balancer's v2 pools, which hold tokens such as WETH, osETH, and wstETH, triggering a sharp selloff in the BAL token and broader crypto markets, the Cryptoticker report said.

The exploit's ripple effect extended to forks of Balancer, including Beets Finance, which also confirmed security breaches on its v2 pools, according to a CoinDesk article. CoinDesk further reported that Berachain, a blockchain platform, halted its network to contain the attack and announced an "emergency hard fork" to mitigate further losses. Meanwhile, Balancer's official account acknowledged the incident, stating that engineering and security teams were investigating "with high priority."

Market reactions were immediate and severe. The BAL token plummeted over 10% intraday, trading near $0.90, while Bitcoin ($BTC) fell below $108,000 amid broader DeFi panic. Traders rushed to de-risk altcoin exposure, exacerbating sell-offs in Ethereum ($ETH), Solana ($SOL), and BNB ($BNB), the Cryptoticker report noted. On-chain data revealed that a dormant wallet withdrew $6.5 million during the attack, signaling urgency among holders to secure assets, Coinpedia reported.

Balancer's vulnerability has raised questions about the security of multi-chain DeFi protocols. PeckShield attributed the breach to either a compromised admin key or a shared contract flaw, noting the attacker's coordinated movement of assets across Ethereum's mainnet and Layer 2 chains in a U.Today report. The outlet emphasized the incident as a "classic Monday in crypto," highlighting the sector's ongoing struggle with liquidity and trust.

Investor sentiment turned cautious as analysts warned of prolonged fallout. Ted Pillows, a crypto commentator, urged users to avoid interacting with affected pools until the situation stabilizes, as reported by Coinpedia. The BAL token's technical outlook appears bearish, with price analysis indicating potential support at $0.88–$0.90 and resistance at $0.95–$1.00, according to Cryptoticker's price analysis. If panic persists, the token could test the $0.80 level, though stabilization near current levels might signal a short-term bottom if Balancer issues a recovery plan.

The attack also exposed broader weaknesses in DeFi's security infrastructure. Risk dashboards now show total DeFi losses in 2025 surpassing $2.8 billion year-to-date, pushing protocols into emergency mode, U.Today's coverage shows. Balancer's history of breaches—including a $500,000 exploit in 2020—underscores the sector's vulnerability to sophisticated attacks, Coinpedia notes.

Regulatory and institutional observers are monitoring the incident's impact on DeFi adoption. The hack coincides with Japan's push to integrate bitcoin mining into grid stability projects, illustrated by a FinanceFeeds article. While governments experiment with blockchain for energy optimization, DeFi's fragility remains a barrier to institutional trust.

Balancer's response will be critical in determining long-term consequences. The protocol must balance transparency with urgency, as delayed action could erode user confidence further. For now, the DeFi sector braces for a prolonged period of scrutiny, with liquidity withdrawals and audit demands surging in the aftermath of the breach, U.Today reported.
