121 Crypto Hacks, Billions Evaporated: DeFi Faces Its Worst Year Since 2022

Decentralized finance is going through one of its worst phases since 2022. According to CryptoRank data, DeFi TVL has dropped by 39% since the beginning of the year. It went from 115 billion dollars in January to about 70 billion in June 2026. In six months, nearly 45 billion dollars of capital have thus left the DeFi ecosystem. This hemorrhage raises a fundamental question: is this a cyclical crypto correction or a deeper structural signal?

DeFi TVL in free fall since January 2026

According to onchain analyses published by CryptoRank on June 24, 2026, DeFi TVL has decreased each month since January. This uninterrupted monthly decline represents a cumulative loss of about 45 billion dollars in half a year. It is equivalent to the total capitalization of several major altcoins evaporated from the crypto sector.

This DeFi decline is primarily explained by the generalized crypto market correction. Bitcoin had reached an all-time high above $122,000 in October 2025, thus bringing the total market capitalization to 4.21 trillion dollars. Since then, the pullback has been sharp:

• Total capitalization hovered around 2.15 trillion dollars at the end of June 2026, a nearly 50% contraction from the peak.
• Bitcoin has lost more than 28% since January 1, Ethereum 43%, and Solana more than 43%.

This relationship is mechanical: a large part of DeFi TVL is denominated in native assets (ETH, SOL, BNB), whose dollar value has sharply declined. The contraction of DeFi TVL thus reflects both user flight and depreciation of assets locked in crypto protocols.

Crypto network Ethereum still dominates, Arbitrum in free fall

The hierarchy of crypto blockchains by TVL remains dominated by Ethereum with 38.9 billion dollars. This alone represents more than half of the entire global DeFi TVL.

Among the top ten chains, Arbitrum records the largest proportional contraction: -55.3% at 1.3 billion dollars. This level brings Ethereum’s layer-2 back to its end-2022 capital.

BNB Chain (-22.7%) and Base (-5.2%) fare better, while Solana falls by 40.5% to 4.93 billion dollars. This level remains significant but is markedly down from the ambitions displayed in 2025.

Tron and Hyperliquid, the two exceptions worth attention

In this generally degraded picture, two crypto blockchains stand out as anomalies. Tron and Hyperliquid are indeed the only ones among the top ten by TVL to have recorded positive growth in 2026.

Tron shows a 5% increase, raising its TVL to 4.63 billion dollars. This resilience is explained more by its function than by a resurgence of speculative activity. Tron remains the crypto network of reference for settlement in USDT (Tether stablecoin). A large portion of its TVL is concentrated in staking, lending, and stablecoin transaction protocols.

Rising 6.7% to 1.52 billion dollars, Hyperliquid presents a more interesting profile from a usage perspective. Having become the leading onchain perpetual contracts market, the crypto protocol attracted regular flows throughout the year thanks to its expanding HyperEVM ecosystem (lending, liquid staking, and DeFi primitives). According to Fortune, it even appears in the Crypto 100 ranking.

121 crypto hacks in 2026: the second factor in the DeFi debacle

The crypto market correction is not the only cause of the decline of DeFi TVL. A wave of rare intensity hacks has significantly increased the pressure on the sector.

According to CryptoRank, 121 hacks have been recorded since the beginning of the year for total losses amounting to roughly 942 million dollars. Worse yet! Only the second quarter of 2026 concentrated 85 crypto incidents, representing about 775 million dollars stolen. This makes Q2 2026 the most active quarter ever recorded in terms of exploits.

The two most devastating attacks occurred in April, within a few days:

• Drift Protocol suffered a breach estimated between 280 and 295 million dollars.
• KelpDAO was victim to a LayerZero cross-chain bridge vulnerability that cost it 293 million dollars.

Alone, these two crypto attacks represent more than half of the sector’s annual losses.

One thing is certain: the DeFi market is undergoing a marked correction in 2026. The ability of crypto protocols to restore technical trust will be the main performance indicator to watch in the coming months.
