The theft of $292 million worth of rsETH from KelpDAO occurred at a highly unfavorable time for the DeFi industry. Prior to this, the security breach at Drift Protocol on April 1 and the March collapse of the Venus lending protocol had already dealt a severe blow to market confidence. After this incident, the entire DeFi sector saw cumulative capital outflows of about $10 billion over the weekend.

The stacking of multiple crises makes DeFi’s predicament even harder to avoid. Although the open-source decentralized finance ecosystem still exists, it is gradually losing its core position as the default gateway for on-chain finance. Stablecoins, tokenized government bonds, and compliant settlement channels continue to expand at a rapid pace, while permissionless native protocols keep bearing a market-imposed trust discount.

A list of 2026 theft incidents circulating on social platform X directly reflects the industry’s pessimistic mood.

Some security incidents have already undergone complete post-incident reviews, while some risks are still fermenting, and many events blur the lines between protocol vulnerabilities, cross-chain bridge failures, and the theft of users’ assets. This article mainly analyzes the confirmed security incidents in 2026 and the industry pattern shifts exposed behind them.

The industry’s current situation is vastly different from the heyday of DeFi’s summer in 2020 and the bull market of 2021. That glory now only remains in memory. Back then, DeFi told the market a story of openness, efficiency, and composability; by 2026, these traits still exist, but they no longer come with their former halo and market belief.

Every major token theft raises users’ trust cost for participating in DeFi. Meanwhile, the fastest-growing and most secure areas of on-chain finance are gradually turning into payment networks, tokenized government bonds, and compliant token products—not the complex native DeFi token ecosystem.

The real test for the industry today is whether open-source DeFi can quickly rebuild market trust and maintain its position as the main on-chain entry point. At present, the entire sector is not heading toward extinction; it is instead being squeezed in terms of space.

DeFi’s security risks are no longer just smart contract vulnerabilities

After encountering major hacker attacks, the most common mistake people make is to attribute all incidents to smart contract code vulnerabilities. The event in which Drift Protocol lost about $285 million proves that this kind of thinking is already outdated.

Chainalysis, an on-chain data analytics firm, disclosed that this attack resulted from permission abuse, an administrator pre-signing operation vulnerability, and false collateral assets—not a simple defect in code statements. The market also realized that many of today’s DeFi risks are hidden in governance permissions, signature mechanisms, operational structures, and more.

This fundamental shift changes the underlying objects users need to place trust in. Code audits and contracts validated by the market remain important, but they can no longer cover the full risk chain: signature nodes, cross-chain bridges, oracles, and market parameter configurations all contain vulnerabilities. When protocols span multiple public chains, management committees, liquidity platforms, and collateral derivatives, the speed at which the attack surface expands far outpaces the speed at which updates to decentralized narratives occur.

The post-mortem for the Venus protocol also exposed similar issues, though the risk forms were different. By using overvalued assets as collateral for borrowing, the attackers extracted approximately $14.9 million in assets, leaving the protocol with over $2 million in bad debt. Although the cause differs from Drift, the conclusion is the same: when liquidity is weak and conditions at the structural margins are abnormal, leading DeFi lending platforms still easily fall into asset crises.

Next came the sudden blow-up of KelpDAO. According to CryptoSlate statistics, this vulnerability directly triggered about $10 billion in capital runs and exits across the entire DeFi market, forcing all rsETH-related markets to be frozen. Even if market sentiment later stabilized and outflow data was revised, the signal remained unmistakable: when users face cross-chain complexity, collateral uncertainty, and systemic contagion risks, their first choice is to withdraw funds.

This trend also matches the 2026 security report released by the security firm TRM: in 2025, most of the industry’s stolen losses came from attacks on infrastructure, which had already surpassed simple smart contract vulnerabilities.

The DeFi trust crisis is becoming increasingly difficult to isolate, because what the industry needs to defend is no longer just the code itself, but the entire complex operating system built on top of it.

On-chain finance is still growing, but funds are flowing into safer products

The overall capital picture does not support the claim that “DeFi is completely collapsing.” CryptoSlate data from April shows that:

USDT market cap is now $185 billion, and USDC market cap is $78 billion;

Total stablecoins on the Tron network are $86.958 billion, and total stablecoins on the Solana network are $15.726 billion.

The Ethereum chain still retains the core stock of native DeFi capital. What the market shows more is a shift in capital concentration and migration, not an exit from the whole system.

The redirection of funds into low-volatility investment tracks is even more obvious. As of March 12, 2026, the size of tokenized U.S. government bonds has reached $10.9 billion, with more than 55,000 holders.

Users are still using blockchains for settlement and asset attestation, but they are no longer willing to put assets into native DeFi projects with complex structures and higher risk.

Market segmentation is very clear:

Signals of trust pressure and capital outflows:

KelpDAO’s $292 million theft triggered about $10 billion in withdrawals across the entire industry;

Drift’s permission vulnerability cut the locked amount in half;

Venus exposed lending risks marked by weak liquidity and frequent bad debt occurrences.

Signals of on-chain growth benefits:

The combined total market cap of USDT+USDC is about $263 billion;

The tokenized U.S. government bond size is $10.93 billion, with more than 55,000 holders;

Visa continues to advance USDC settlement and is building an institutional-grade stablecoin ecosystem.

Capital is clearly gathering toward products with clear logic, sufficient collateral, and suitability for institutional participation.

In Visa’s 2026 stablecoin strategy report, it is worth paying close attention: its data shows that the total stablecoin supply increased by over 50% in 2025—from $186 billion at the beginning of the year to $274 billion by year-end; and it also proposes that 2026 will be the year when institutions officially begin laying out stablecoins, meaning the stablecoin sector is moving toward mainstream standardization.

The same is true at the settlement layer. Visa disclosed that its USDC monthly settlement volume has already exceeded an annualized scale of $3.5 billion.

Although the numbers themselves account for only a small share across the entire stablecoin market, the industry significance is profound: compliant traditional financial infrastructure is connecting to on-chain networks, no longer needing to rely on the full ecosystem narrative of native DeFi.

The core of industry competition: who will control future on-chain infrastructure

CryptoSlate previously noted that compliant institutions are competing for an on-chain funding pool worth over $330 billion, including about $317 billion in stablecoins and nearly $13 billion in tokenized government bonds.

These funds continuously pursue advantages such as high speed, programmability, and nonstop 7×24 settlement. Market attention is concentrated on leading assets and core settlement networks, rather than all kinds of niche governance experiment projects.

Compared with the 2021 bull cycle, the gap is especially stark.

In past cycles, DeFi encompassed both the underlying infrastructure and end products: the locus of innovation, the source of high yields, and a blueprint for future finance were all concentrated here. By 2026, the future of on-chain finance is being separated from the chaotic risks of native DeFi and repackaged.

Tokenized funds achieve round-the-clock circulation and rapid settlement, while stablecoins support payments and treasury operations; institutions enjoy blockchain advantages while firmly controlling compliance, counterparty risk, and market structure.

CryptoSlate’s project shutdown report shows that in Q1 2026, more than 80 crypto projects had officially shut down or entered liquidation. While this is not limited to DeFi, it is enough to demonstrate that capital has run out of patience for projects that cannot generate long-term value, stable yields, and real-world applications.

Crypto spot ETFs are also part of this broader trend. Compliant products continue to receive market funds and attention, and users and institutions prefer infrastructure that offers blockchain advantages without having to bear the high-trust risks of native DeFi.

This leaves native DeFi with its own positioning, but the space is being narrowed: open composability and permissionless innovation still have value, serving as a laboratory for innovation of financial primitives—DeFi explores and tests first before compliant mainstream products absorb and popularize new models.

The core contradiction in the industry today is still trust compression.

Native open-source DeFi is losing narrative dominance. If it cannot quickly rebuild trust, optimize its operational architecture, and prove the irreplaceability of its complex design, it will gradually lose its position as the on-chain front-end entry point for finance.

At present, the key power struggle in the industry is already clear: who will capture the next wave of on-chain demand? And for now, safer and more compliant on-chain packaged products are taking the lead.
