The potential $8 billion bomb in DeFi has only exploded with $100 million so far

Fund managers, a role once trusted and later disenchanted in the stock market, carried the wealth dreams of countless retail investors during the booming period of A-shares.

At that time, everyone was chasing fund managers who graduated from prestigious schools and had impressive resumes, believing that funds were a less risky and more professional alternative to direct stock trading.

However, when the market fell, investors realized that so-called "professionalism" could not combat systemic risks. Worse still, while they earned management fees and performance bonuses, profits were their own achievement, but losses were borne by the investors.

Today, when the role of "fund manager" arrives on-chain under the new name "Curator," the situation has become even more perilous. They do not need to pass any qualification exams, undergo scrutiny from regulatory bodies, or even disclose their true identities.

They only need to create a "vault" on a DeFi protocol, using absurdly high annualized returns as bait to attract hundreds of millions of dollars in funds. And where this money goes and what it is used for remains unknown to the investors.

$93 Million Vanished

On November 3, 2025, when Stream Finance suddenly announced the suspension of all deposits and withdrawals, a storm swept through the DeFi world.

The next day, the official statement revealed that an external fund manager had been liquidated during the market's severe fluctuations on October 11, resulting in a loss of approximately $93 million in fund assets. The price of Stream's internal stablecoin xUSD plummeted, collapsing from $1 to a low of $0.43 within just a few hours.

This storm was not without warning. As early as 172 days prior, Yearn's core developer Schlag had warned the Stream team. At the eye of the storm, he bluntly stated:

"Just a single conversation with them and a 5-minute browse of their Debank would make it clear that this would end badly."

A conversation between Yearn Finance and Stream Finance

Stream Finance is essentially a yield aggregation DeFi protocol that allows users to deposit funds into vaults managed by so-called "external curators" to earn returns. The protocol claims to diversify investments across various on-chain and off-chain strategies to generate profits.

This collapse was caused by two main reasons: first, the Curator used user funds for opaque off-chain trading, which was liquidated on October 11; second, on-chain analysts further discovered that Stream Finance also engaged in recursive lending with Elixir's deUSD, leveraging a small amount of real capital to amplify their leverage several times. This "left foot stepping on the right foot" model, while not the direct cause of the losses, greatly magnified the systemic risks of the protocol and laid the groundwork for subsequent chain reactions.

These two issues combined led to a catastrophic chain reaction: $160 million in user funds were frozen, the entire ecosystem faced $285 million in systemic risk, Euler protocol incurred $137 million in bad debts, and 65% of Elixir's deUSD was backed by Stream assets, leaving $68 million hanging on the brink of collapse.

So, what exactly is this "Curator" model that seasoned developers can see through at a glance yet still attracted over $8 billion in funds? How did it gradually push DeFi from the ideal of transparency and trustworthiness into today's systemic crisis?

The Fatal Transformation of DeFi

To understand the root of this crisis, we must return to the origins of DeFi.

Traditional DeFi protocols represented by Aave and Compound are fundamentally appealing because of "Code is law." Every deposit and every loan must adhere to the rules written in smart contracts, which are public, transparent, and immutable. Users deposit funds into a massive public pool, and borrowers must provide over-collateralization to borrow funds.

The entire process is algorithm-driven, with no human manager intervention. Risks are systemic and calculable, such as smart contract vulnerabilities or liquidation risks in extreme market conditions, but not the human risks posed by a "fund manager."

However, in this cycle, a new generation of DeFi protocols represented by Morpho and Euler, in pursuit of yield, has implemented a new type of fund management approach. They believe that Aave's public pool model is inefficient, with a large amount of capital idling and unable to maximize returns.

Thus, they introduced "Curators." Users no longer deposit money into a unified pool but choose individual "vaults" managed by Curators. Users deposit money into the vaults, while Curators are fully responsible for how to invest and generate returns with that money.

The expansion of this model is astonishing. According to DeFiLlama data, as of now, the total locked value of just the two major protocols, Morpho and Euler, has exceeded $8 billion, with Morpho V1 reaching $7.3 billion and Euler V2 having $1.1 billion. This means that over $8 billion in real money is being managed by numerous Curators with diverse backgrounds.

This sounds appealing; professionals do professional things, and users can easily obtain higher returns than Aave. But peeling back the glamorous exterior of this "on-chain wealth management," its core is strikingly similar to P2P.

The core risk of P2P was that ordinary users, as funders, could not assess the true creditworthiness and repayment ability of the borrowers on the other end. The high-interest rates promised by the platform were backed by immeasurable default risks.

The Curator model perfectly replicates this. The protocol itself is merely a matchmaking platform; users' money seems to be invested with professional Curators, but in reality, it is invested in a black box.

Taking Morpho as an example, users can see various vaults established by different Curators on its website, each boasting enticing APYs (annual percentage yields) and brief strategy descriptions.

For instance, "Gauntlet" and "Steakhouse" in this image are the Curators of the respective vaults.

Users only need to click to deposit their assets like USDC into these vaults. But herein lies the problem: apart from the vague strategy descriptions and fluctuating historical returns, users often know nothing about the internal operations of the vaults.

The core information regarding vault risks is hidden on an inconspicuous "Risk" page. Even if users are inclined to click on that page, they can only see the specific holdings of the vault. Core information that determines asset safety, such as leverage ratios and risk exposures, is nowhere to be found.

The Curator of this vault has even failed to submit a risk disclosure. Inexperienced users find it difficult to assess the safety of the underlying income-generating assets in the vault.

Morpho's CEO Paul Frambot once said, "Aave is a bank, while Morpho is the infrastructure of a bank." But the subtext of this statement is that they only provide tools, while the real "banking business," which is risk management and capital allocation, is outsourced to these Curators.

The so-called "decentralization" is limited to the moment of deposit and withdrawal, while the most crucial risk management phase in the asset's lifecycle is entirely in the hands of an unregulated "Curator" of unknown background.

It can truly be said: "Decentralized money, centralized management."

The relative safety of traditional DeFi protocols is precisely because they maximally eliminate the variable of "human." In contrast, the Curator model of DeFi protocols has reintroduced the greatest and most unpredictable risk—"human"—back into the blockchain. When trust replaces code, and transparency turns into a black box, the cornerstone of DeFi safety has crumbled.

When "Curators" Collude with Protocols

The Curator model merely opened Pandora's box, while the tacit collusion of interests between the protocol parties and Curators completely unleashed the demons inside.

Curators typically profit by charging management fees and performance bonuses. This means they have a strong incentive to pursue high-risk, high-return strategies. After all, the principal is the users', and they bear no responsibility for losses; if they win the gamble, the bulk of the profits goes into their own pockets.

This "internalizing profits, externalizing risks" incentive mechanism is almost tailor-made for moral hazard. As Arthur, the founder of DeFiance Capital, criticized, under this model, Curators' mindset is: "If I mess up, it's your money. If I get it right, it's my money."

Even more frightening is that the protocol parties not only fail to play the role of regulators but instead become accomplices in this dangerous game. To attract TVL (Total Value Locked) in fierce market competition, protocol parties need to offer astonishingly high APYs to attract users. And these high APYs are generated by those Curators employing aggressive strategies.

Therefore, protocol parties not only turn a blind eye to the risky behaviors of Curators but may even actively collaborate with or encourage them to set up high-interest vaults as marketing gimmicks.

Stream Finance is a typical example of such opaque operations. According to on-chain data analysis, Stream claimed to have a total locked value (TVL) of up to $500 million, but according to DeFillama data, Stream's TVL peaked at only $200 million, meaning that over three-fifths of user funds flowed into unknown off-chain strategies operated by some mysterious proprietary traders, completely detached from the transparency that DeFi should have.

Another Curator protocol, RE7 Labs, exposed this interest entanglement in a statement released after the Stream collapse. They admitted that before launching Stream's stablecoin xUSD, they had already identified its "centralized counterparty risk" through due diligence. However, due to "significant user and network demand," they still decided to launch the asset and set up an independent lending pool for it. In other words, for the sake of traffic and popularity, they chose to dance with risk.

When the protocol itself becomes an advocate and beneficiary of high-risk strategies, so-called risk assessments become mere formalities. What users see is no longer real risk warnings but a meticulously crafted marketing scam. They are led to believe that those double-digit or triple-digit APYs are the magic of DeFi, unaware that behind them lies a trap leading to the abyss.

The Collapse of Dominoes

On October 11, 2025, the cryptocurrency market experienced a bloodbath. In just 24 hours, the total liquidation amount across the network approached $20 billion, and the liquidity crisis and hidden risks brought about by this liquidation were spreading throughout the entire DeFi ecosystem.

Analysts on Twitter generally believe that many DeFi protocol Curators, in pursuit of yield, commonly adopted a high-risk play off-chain: "selling volatility."

The essence of this strategy is to bet on market stability; as long as the market remains calm, they can continuously charge fees and make money. However, once the market experiences severe fluctuations, they can easily lose everything. The market crash on October 11 became the trigger that detonated this giant bomb.

Stream Finance was the first significant domino to fall in this disaster. Its officials later confirmed that an external fund manager had been liquidated during the market's severe fluctuations on October 11, resulting in a loss of approximately $93 million in fund assets. Although the officials did not disclose the specific strategy employed, market analysis generally pointed to high-risk derivatives trading.

However, this was just the beginning of the disaster. Since Stream's tokens, such as xUSD and xBTC, were widely used as collateral and assets in DeFi protocols, its collapse quickly triggered a chain reaction affecting the entire industry.

According to preliminary analysis by DeFi research institution Yields and More, the direct debt exposure related to Stream reached as high as $285 million, revealing a massive risk contagion network: the biggest victim was the Elixir protocol, which, as one of Stream's main lenders, had lent up to $68 million in USDC to Stream, accounting for 65% of Elixir's total reserves of the stablecoin deUSD.

RE7 Labs, once a collaborator, has now also become a victim. Its vaults on multiple lending protocols face millions of dollars in bad debt risk because they accepted xUSD and Elixir-related assets as collateral.

Wider contagion unfolded through complex "repeated collateralization" paths, as Stream's tokens were collateralized in mainstream lending protocols like Euler, Silo, and Morpho, which were further nested by other protocols. The collapse of one node quickly transmitted through this spider-web-like financial network to the entire system.

The hidden dangers buried in the liquidation event of October 11 extend far beyond just Stream Finance. As Yields and More warned, "This risk map is still incomplete, and we expect more affected liquidity pools and protocols to be discovered."

Another protocol, Stables Labs, and its stablecoin USDX, have recently encountered similar situations, facing scrutiny from the community.

Issues like those exposed by Stream Finance reveal the fatal flaws of the Ce-DeFi model: when the transparency of the protocol is lacking and power is overly concentrated in the hands of a few, the safety of user funds entirely relies on the integrity of the project parties, lacking effective technical and regulatory constraints.

You Are the Yield

From Aave's transparent on-chain banking to Stream Finance's asset management black box, DeFi has undergone a fatal evolution in just a few years.

When the ideal of "decentralization" is distorted into a carnival of "de-regulation," and the narrative of "professional curation" obscures the reality of opaque fund operations, what we end up with, as Yearn developer Schlag said, is not better finance but a "worse banking system."

The most profound lesson from this crisis is that we must re-examine the core value of DeFi: transparency is far more important than the label of decentralization itself.

An opaque decentralized system is far more dangerous than a regulated centralized system. Because it lacks the credibility endorsement and legal constraints of centralized institutions, and it also lacks the public, verifiable checks and balances that a decentralized system should have.

Matt Hougan, Chief Investment Officer of Bitwise, once said a famous line to all investors in the crypto world: "There are no double-digit returns in the market without risk."

For every investor attracted by high APYs, before clicking the "Deposit" button next time, they should ask themselves one question:

Do you really understand where this yield comes from? If you don't understand, then you are that yield.
