Balancer, once one of the largest automated market makers in decentralized finance, has proposed winding down the protocol after its post-exploit restructuring failed to generate enough revenue to keep operating. Balancer Labs CEO Marcus Hardt published the proposal on the governance forum Monday, saying he underestimated how much a $128 million exploit in November would weigh on adoption even after the company rebuilt. If approved, it would end the run of a protocol that helped define automated market maker design and shaped how pools with multiple tokens and weighted assets work across the industry. The move also closes a chapter that began with one of the larger DeFi exploits of 2025, one that drained user funds from pools that had been considered conservative by the standards of the sector.
Revenue never recovered
The numbers behind the decision are stark. Monthly protocol revenue collapsed to $56,781 in August, according to DefiLlama data, down from $1.13 million in October 2025, the month before the exploit. That is a fall of roughly 95 percent in under a year. The attack targeted composable stable pools on the legacy v2 protocol and drained user funds, and confidence in the platform never fully returned even after the team patched the vulnerability and adjusted fee structures. Stablecoin pools were the core of Balancer’s volume story for years, which meant the exploit hit the exact segment that drove its daily activity.Balancer Labs shut down in March as part of a restructuring, with executives opting to continue operating the protocol under a leaner structure rather than shutting everything down at once. Hardt said Monday that the restructuring succeeded in cutting costs and delivering the products promised to tokenholders, but the revenue side of the plan fell short. Most protocol revenue still comes from v2, and v3 revenue has not grown fast enough to replace it. In his words, the new version failed to win the volume the team projected when the restructuring was signed off. Cost cuts can only stretch a runway so far when the top line keeps shrinking.
“The product worked. It did not sell enough,” Hardt said in a statement on X.
What happens to the treasury
The wind-down proposal calls for distributing Balancer’s remaining treasury, worth more than $9 million, to BAL tokenholders on a pro-rata basis. The first distribution is scheduled for May 2027, when holders would burn their BAL in exchange for their share of treasury assets. A second distribution would return unspent wind-down funds and unclaimed assets from the first round, followed by a final sweep six months later to close out anything left in operational wallets. The staged structure gives the team time to settle outstanding obligations, including any residual commitments to liquidity providers and audit firms.Hardt argued that delaying the shutdown would only eat into the treasury without changing the outcome. “Continuing on the current path spends the treasury to arrive at the same place later. That treasury belongs to BAL holders,” he wrote. A snapshot vote is scheduled for September 25 to 29, and tokenholders must approve the plan before it proceeds. Governance participation in Balancer votes has historically been low, so turnout will shape how representative the result is, but the economics leave little room for a credible alternative plan.
A broader DeFi problem
Balancer is not alone. Several DeFi protocols have faced profitability problems this year as trading volume concentrates on a handful of venues and incentive programs wind down. Uniswap continues to dominate Ethereum-ecosystem volume, while Solana and BNB Chain have taken share from Ethereum-based platforms. A 2026 report from SwapSpace using DeFiLlama data showed Ethereum’s share of global DEX volume falling to 19.3 percent in 2025 from 46.2 percent in 2021, a shift that leaves mid-tier AMMs fighting for a shrinking slice of a market that has itself become more competitive on fees. Protocols that once lived on token incentives now face users who route purely on price, and price favors scale.The exploit aftermath compounded the trend. Security incidents on Ethereum-based protocols have repeatedly shown that liquidity, once withdrawn, rarely comes back at full scale. Balancer’s v3 launch was meant to mark a fresh start, and the team shipped it on schedule, but volume followed the users rather than the technology. Liquidity providers moved to venues with deeper pools and cheaper routing, and aggregators followed the liquidity, closing the loop against a recovery. Once aggregators rank a venue below the top three, its share of routed volume decays quickly, and Balancer never broke back into that tier.The proposal also raises questions about governance-based wind-downs as a template. If the vote passes, BAL holders will recover value from a treasury that would otherwise bleed out over months of low revenue. The mechanism, burn tokens for a pro-rata treasury share, mirrors wind-downs in traditional fund structures and could become more common as older DeFi protocols reach the end of their lifecycle. Several smaller protocols have already run similar processes quietly this year, though none at Balancer’s profile. A clean wind-down at this scale would give the industry a worked example to copy.For now, attention shifts to the September vote, where holders must weigh a certain, modest recovery against a low-probability turnaround. The episode is a data point in a longer debate about whether mid-sized DeFi protocols can survive a security incident at scale, or whether the market now only supports a small number of venues at the top. Balancer’s own history, from a design innovator to a wind-down candidate in under five years, suggests the answer is trending toward consolidation.
