Two headlines hit the internet within hours of each other this week, and together they map the current state of DeFi’s security theater.
StakeWise DAO executed contract calls to recover approximately $19.3 million in osETH, along with an additional $1.7 million in osGNO, from the Balancer V2 exploit that drained between $110 million and $128 million across multiple chains.
At the exact moment, Stream Finance froze deposits and withdrawals after an external fund manager disclosed a $93 million loss, sending its staked stablecoin, xUSD, into a depeg that bottomed out at somewhere between 30 and 50 cents on the dollar.
One story shows DeFi’s defense toolkit finally working at speed; the other exposes the brittleness that remains when protocols outsource risk to opaque counterparties.
The contrast isn’t cosmetic. StakeWise’s partial recovery of about 15% of the total Balancer loss came from levers DeFi has spent years building: emergency multisigs, contract-level clawbacks, and DAO governance structures that can move capital within hours.
Stream’s collapse can be traced back to a structural bet on hybrid CeDeFi, which consisted of farming yields through an external manager without real-time risk dashboards or transparent collateral monitoring.
The $93 million vanished off-chain, beyond the reach of any smart contract or validator coordination. What worked and what broke both matter because they define the menu of tools available when the next nine-figure exploit lands.
Balancer confirmed the incident on November 3, targeting V2 Composable Stable Pools.
Loss tallies evolved as investigators traced the drains across chains of custody. The protocol offered a white-hat bounty of up to 20%, hoping to convert the attacker into a bug hunter with a payday.
Berachain, which runs Balancer-style pools on its native DEX, moved faster: validators executed a coordinated network halt, performed an emergency hard fork to isolate the vulnerable contracts, and resumed operations with the exploit contained.
The maneuver consisted of a pause and rollback, something that only works when a chain is young and centralized enough to coordinate validator action without governance deadlock.
StakeWise’s playbook provides the most compelling evidence that DeFi’s emergency architecture can withstand intense pressure.
The DAO’s multisig triggered contract calls that returned 5,041 osETH and 13,495 osGNO to protocol control.
The team committed to pro-rata distributions based on pre-exploit balances, turning a catastrophic loss into a partial haircut.
This isn’t theoretical: the funds moved on-chain, the DAO published the plan publicly, and multiple outlets corroborated the figures. The speed matters as much as the outcome.
Traditional finance recoveries can take months of litigation and often yield only pennies on the dollar. StakeWise executed in days, using tools native to the protocol.
The toolbox and its limits
Three mechanisms made StakeWise’s recovery possible: emergency multisigs with narrow, predefined powers, contract-level clawback functions that allow governance to reverse specific transactions, and a DAO structure capable of voting and executing within a single block cycle.
Berachain added the fourth option of chain-level intervention through validator consensus. Together, these tools enabled partial and rapid recoveries.
They don’t prevent exploits, but they create a credible ex-post response that narrows the attacker’s time window and reduces the payoff.
The limits are immediately evident in the numbers. StakeWise recovered $19.3 million from a $128 million drain, representing approximately 15%. Balancer’s white-hat bounty remains unclaimed as of press time.
Berachain’s rollback protected its own ecosystem but was unable to reverse transactions on the Ethereum mainnet or other affected chains.
Every lever DeFi pulled worked, and users still absorbed $100 million in losses. The toolbox isn’t empty, but it’s also not sufficient to stop a determined, sophisticated attacker who understands the protocols better than the auditors.
Stream Finance exposes the architectural flaw that no amount of on-chain tooling can fix. The protocol disclosed that an external fund manager lost approximately $93 million, prompting an immediate freeze on deposits and withdrawals.
Stream hired Perkins Coie to investigate, but the damage had already propagated. The protocol’s staked stablecoin, xUSD, depegged sharply as price trackers and newsrooms reported intraday lows between 50% and 70% of its par value.
The mechanics differ from a smart contract exploit, as no attacker drained a pool, no validator coordination could reverse the loss, and no DAO vote could claw back funds held off-chain by a third-party manager.
This is the CeDeFi compromise in its rawest form. Protocols promise DeFi’s composability and on-chain transparency while farming yield through traditional fund managers who operate under entirely different risk frameworks.
When the external manager fails, whether through fraud, operational error, or market losses, the stablecoin backed by that capital loses its peg, and the protocol has no emergency lever to pull.
Users discover too late that their “decentralized” stablecoin depended on trust in an entity they never saw, operating in a jurisdiction they can’t reach, under terms they never reviewed.
Second-order math
The existence of emergency multisigs and clawback functions raises the floor for exploit victims, as no value recovered is no longer the default; however, it also creates a moral hazard.
Protocols may underinvest in security audits, reasoning that governance can backstop losses ex post. Regulators will take note: if DAOs can reverse transactions and freeze funds, they effectively control the network in ways that resemble fiduciary duties.
That invites policy pressure for proof-of-reserves dashboards, mandatory risk disclosures, and stricter licensing for anything labeled “decentralized.”
For investors, the due diligence premium has just increased. Yield products built on opaque external managers or hybrid CeDeFi structures now carry a new risk: catastrophic, unrecoverable losses that break stablecoin pegs.
Real-time risk dashboards, transparent collateral monitoring, and on-chain proof-of-reserves stop being nice-to-haves and become table stakes. Protocols that can’t or won’t publish those metrics will trade at a discount, and rightly so.
The macro backdrop sharpens the stakes. Chainalysis tallied more than $2.17 billion in crypto thefts by mid-2025, already surpassing the total for the full year 2024, with projections indicating $4 billion if current trends continue.
DeFi isn’t the only target, but it remains the most liquid and the most vulnerable among them. Every exploit tests whether the ecosystem has built defenses that scale faster than the attack surface.
Who decides the outcome?
The Balancer-StakeWise-Stream sequence isn’t a one-off. It’s a stress test of two competing visions for the future of DeFi.
One side bets that emergency governance, contract-level controls, and validator coordination can create a credible defense that narrows the window for attackers and limits losses.
The other side embraces hybrid structures that trade on-chain transparency for off-chain yield, accepting counterparty risk as the price of competitive returns.
Both visions coexist today, and users allocate capital between them every time they choose a protocol.
What’s at stake isn’t whether exploits occur, but whether DeFi can defend itself sufficiently to remain a credible alternative to traditional finance. StakeWise’s recovery proves the tools exist. Stream’s collapse proves they don’t cover the entire attack surface.
The next $100 million exploit will fall into one of these two buckets, and the outcome will depend on which architecture the protocol chose months or years before the attacker arrived. The market will notice which one survives intact.
