DeFi Crisis Deepens as Balancer Shuts Down Post $128M Hack

Balancer Labs shuts down. Just like that, one of DeFi’s older guard is gone. Four months after a $128 million exploit tore through its v2 pools, co-founder Fernando Martinelli posted a forum announcement this week confirming the corporate entity is winding down. No dramatic farewell tour. No last-minute white knight. Just a quiet admission that the numbers stopped making sense.

How a Rounding Error Became a $128M Disaster

November 3, 2025, is a date the Balancer community won’t forget in a hurry. Attackers exploited a rounding flaw buried inside the protocol’s swap logic, draining liquidity across multiple chains in what turned out to be one of the costlier DeFi hacks of the year.

Not a sophisticated nation-state attack. Not a novel zero-day. A rounding error.

The timing couldn’t have been worse. Balancer had already been bleeding TVL for years. The protocol peaked at $3.3 billion locked in November 2021, and by October 2025, that number had quietly shrunk to $800 million. Then the hack hit, and another $500 million walked out the door in just two weeks. Today, the protocol sits at roughly $158 million TVL. That’s a 95% collapse from peak.

Anyone still surprised that the corporate entity couldn’t survive that?

Why Balancer Labs Finally Pulled the Plug

Martinelli was direct in his forum post: the November exploit left behind “real and ongoing legal exposure,” and keeping the corporate entity alive while it carried that liability made no sense, especially for a company bringing in zero revenue.

That last part is worth sitting with. Zero revenue. Balancer Labs was spending money it didn’t have to chase liquidity in a market that had already moved on. CEO Marcus Hardt acknowledged the team was spending too much on attracting liquidity relative to what the protocol actually earned, and BAL token holders were absorbing the cost of that gap through dilution. 

This is a pattern that repeats itself across DeFi. A protocol raises money in a bull market, builds something real, then spends years printing tokens to subsidise growth that never quite arrives. Eventually, the music stops.

The Protocol Lives On, Sort Of

Before BAL holders panic-sell everything, there’s a bit more to the story. Martinelli made it clear that shutting down Balancer Labs is not the same as shutting down the protocol. 

He pointed out that the protocol is still generating over $1 million in annualised fees, calling it a functioning protocol “buried under a broken tokenomics model and an overweight cost structure.” His words, not mine. And honestly? That framing is more honest than most founders manage when things fall apart.

The plan going forward involves stripping things back hard. BAL emissions would stop entirely, the veBAL governance model gets wound down, and the DAO treasury would capture 100% of protocol fees. There’s also talk of a BAL buyback to give holders an exit if they want one.

Core team members are expected to move into a new entity called Balancer OpCo, though that still needs a governance vote to pass. Nothing is guaranteed.

What Should the Rest of DeFi Take From This?

Honestly, the uncomfortable part of this story isn’t the hack itself. DeFi protocols get hacked. That’s a known risk. The uncomfortable part is that a rounding flaw in swap logic, the kind of thing that auditors are specifically paid to catch, survived long enough to cause nine-figure losses on a protocol that had been running for years.

Balancer’s collapse from $3.3 billion to $158 million in TVL shows just how hard it is for DeFi protocols to recover once trust breaks. Users don’t come back. Liquidity doesn’t come back. And without liquidity, there’s no protocol worth saving.

The next 12 months will be telling. Either the leaner DAO-run version of Balancer finds a reason to exist, or it fades out slowly. Both outcomes are possible. Neither would be surprising.

What brought down Balancer Labs? 

A combination of things. A $128M hack in November 2025 created legal liability, while the corporate entity had already been running without revenue for some time. The two together made continuing untenable.

Will the Balancer protocol still work after this? 

Yes, at least for now. The protocol itself continues under the Balancer Foundation and DAO. A governance vote will decide the restructuring details.

What happens to people holding BAL tokens? 

A buyback programme has been proposed to give holders an exit option. BAL emissions would also stop under the restructuring plan, which changes the token’s supply dynamics significantly.
