The Rosen Law Firm, a US-based law firm that handles investor cases, is investigating possible claims following Balancer’s November 2025 hack. The firm says Balancer may have given wrong or misleading information to investors before the attack.
According to an official announcement, Rosen is looking into potential claims for anyone who purchased Balancer cryptocurrency (ticker: BAL) and could be entitled to compensation without paying any out-of-pocket fees.
How the hack happened
On November 3, 2025, Balancer, a decentralized finance protocol, lost more than $100 million in digital assets due to an exploit. Security firms PeckShield and Cyvers reported that the attacker’s wallet was still taking funds and that total losses had grown to around $128 million.
The attack used weak points in Balancer’s V2 smart contracts, including calculation errors in the pools and problems with controlling access in the vault system. The hackers were able to change balances and take money across different chains very quickly.
Reimbursement plan for investors
Balancer paused some operations after the exploit and later made a plan to pay back the people who had lost their funds by giving back $8 million from the funds recovered.
The money would go only to people in the affected pools, based on how many Balance Pool Tokens they had before the attack. Some funds were also returned in-kind, and whitehat actors who helped recover funds were entitled to 10% bounties. While the reimbursement plan went through community review and governance discussions, full payouts have not been widely confirmed as of February 2026.
Rosen’s law’s role
Rosen Law encourages investors to seek qualified counsel and claims it has extensive experience in securities class actions. Since 2013, it has represented investors globally and has been ranked in the top four by ISS Securities Class Action Services. In 2019, the firm recovered over $438 million for investors, and founding partner Laurence Rosen was named a Titan of the Plaintiffs’ Bar in 2020.
Broader context
The Balancer hack shows how risky investing in cryptocurrencies can be, especially when technical errors in smart contracts are exploited. Recovering funds through class actions gives investors a way to get some compensation when the platform fails to fully cover losses. Cases like this also push crypto companies to improve security and transparency, which could make the market safer in the future.
