Top 10 Crypto Hacks Total $5.7 Billion, But Proposed DeFi Fix Would Only Have Helped One

The 10 largest crypto hacks have drained a combined $5.68 billion from the industry, yet a structural defense proposed by a DeFiLlama developer would have applied to just one of them.

Data places the $285 million Drift Protocol exploit alongside legacy disasters such as Mt. Gox and FTX. The list has renewed debate over whether Decentralized Finance (DeFi) security is improving fast enough.

Lending Protocols Face Higher Risk

A DeFiLlama developer proposed combining cross-protocol tranching with 24-hour withdrawal rate limits. The idea splits depositor capital into senior and junior tranches, then caps daily withdrawals at the junior tranche’s size.

According to the developer’s data, 3.92% of lending protocols with peak total value locked above $50 million have suffered an 80%-plus drain.

That rate is 4.6 times higher than the 0.85% observed across all protocol categories. Cross-protocol tranching could reduce the probability of total loss for senior depositors by roughly 80%, the developer estimated.

The combination would enforce that senior-tranche capital can always be made whole, provided the hack does not exceed the junior buffer within a single day.

Most Losses Fall Outside DeFi Lending

However, the top-10 list exposes the proposal’s limits. Drift Protocol, the largest DeFi hack of 2026, lost $285 million through a governance takeover that drained vaults in roughly 12 minutes.

Tranching plus rate limits could have slowed that drain and preserved senior depositor funds.

The remaining nine incidents fall into two categories that tranching does not address. Five were centralized exchange failures, including the $1.5 billion Bybit breach and the collapses of FTX and Mt. Gox.

Four were cross-chain bridge exploits affecting Ronin Network, Poly Network, Wormhole, and the BNB Bridge.

Security experts say DeFi protocol code is becoming harder to exploit, shifting the main attack surface to people and operational security weaknesses.

“I really hope Hyperliquid is in a war room right now, assuming they’ve already been compromised and reviewing every last thing they’ve done for the last year and a half,” quipped Laura Shin, host of the Unchained podcast.

While the data suggests that tranching strengthens one layer of defense for lending, the industry’s largest dollar losses remain tied to centralized infrastructure and human error.
