How the $1.46 Billion Bybit Hack Stress-Tested Liquid Staking Derivatives — And Why stETH Survived

Protocol Primer

On February 21, 2025, the cryptocurrency industry witnessed the largest single exchange hack in its history. Dubai-based Bybit lost approximately $1.46 billion worth of Ethereum and staking derivatives — including 401,346 ETH, 90,375 stETH, 8,000 mETH, and 15,000 cmETH — when North Korean hacking group Lazarus exploited a masked user interface on the exchange’s cold wallet multisig transfer. By the time markets opened on February 22, the full scale of the breach was still being digested, and liquid staking tokens found themselves at the center of an unprecedented stress test.

Liquid staking derivatives, particularly Lido’s stETH, have grown into a cornerstone of decentralized finance. They allow Ethereum holders to stake their ETH while retaining a tradeable token — effectively unlocking liquidity from an otherwise illiquid position. With Ethereum trading at $2,764 on February 22 according to CoinMarketCap data, the total value of stETH stolen represented a significant chunk of the liquid staking market. The question on everyone’s mind was whether these derivative tokens would hold their peg and whether DeFi infrastructure could absorb the shock.

Key Innovations

What makes liquid staking derivatives like stETH structurally resilient is their redemption mechanism. Each stETH is backed 1:1 by staked ETH on the Beacon Chain, plus accumulated rewards. The token’s value doesn’t depend on market confidence in a single entity — it’s anchored to the underlying staked position on Ethereum itself. This design proved critical during the Bybit aftermath.

According to blockchain analytics from Arkham Intelligence, approximately $253 million worth of stETH was rapidly swapped for native ETH through decentralized exchanges — primarily via ParaSwap, which routed orders through Uniswap. This represented a massive, forced liquidation event. Yet stETH maintained its peg with minimal deviation. The DEX liquidity pools, despite being stressed, handled the volume without catastrophic slippage — a testament to the depth that the liquid staking ecosystem has built over the past two years.

The hackers’ approach also revealed something important about staking derivative infrastructure. Converting stETH to ETH was relatively straightforward through DEXs, but converting native ETH into stablecoins proved far more difficult. Tether CEO Paolo Ardoino confirmed that 181,000 USDT connected to the hack was frozen on-chain. This asymmetry — easy to swap within DeFi, hard to exit into fiat — demonstrates the layered security that DeFi composability can provide during crisis scenarios.

Tokenomics Breakdown

The stolen tokens represented a complex basket. The 401,346 ETH was native Ethereum, immediately spendable. But the 90,375 stETH and the additional mETH and cmETH positions required conversion before they could be moved across chains. This friction, built into the tokenomics of liquid staking derivatives, acted as an inadvertent speed bump. Bybit CEO Ben Zhou confirmed that the hackers had begun using cross-chain bridges like Chainflip to convert ETH into Bitcoin — a tactic seen in the 2022 FTX hack — but the additional conversion steps bought investigators valuable time.

From a supply perspective, the liquid staking market absorbed the selling pressure remarkably well. Ethereum’s 24-hour spot trading volume across all exchanges exceeded $30 billion on February 22, according to market data. Even if the hackers had liquidated all holdings simultaneously, the selling pressure would have been marginal relative to total throughput. ETH had already recovered from an 8% intraday drop to $2,600 back to $2,764 — a V-shaped recovery that underscored the market’s capacity to absorb shocks.

Roadmap Reality Check

The Bybit hack exposes a fundamental tension in liquid staking’s future trajectory. On one hand, the tokens performed exactly as designed — maintaining pegs, providing sufficient DEX liquidity, and creating natural friction for bad actors. On the other hand, the ease with which $253 million in stETH was converted through DeFi protocols raises questions about whether additional safeguards should be implemented.

Several proposals have emerged from the incident. Delayed withdrawals for large unstaking transactions, enhanced on-chain monitoring for wallets flagged by intelligence firms, and circuit-breaker mechanisms that could temporarily halt large swaps during confirmed security incidents are all being discussed. The challenge is implementing these without undermining the core value proposition of liquid staking — which is, by definition, instant liquidity.

Lido, as the dominant liquid staking protocol, faces particular scrutiny. Its growing share of total Ethereum staking has raised governance concerns, and the Bybit incident adds a new dimension: when stETH becomes a primary target in exchange hacks, the protocol’s infrastructure becomes effectively part of the broader security perimeter.

Investor Takeaway

For altcoin investors watching the February 22 fallout, the liquid staking story offers a nuanced picture. Solana traded at $172.16 — down 11.48% for the week — while BNB held relatively steady at $668.57. But stETH’s resilience during a forced liquidation event involving nearly $253 million in swaps is a genuine signal of market maturity. The derivative didn’t just survive; it barely flinched.

The real lesson from February 22 isn’t about which tokens went up or down. It’s about infrastructure under fire. Liquid staking derivatives passed their most severe real-world test with a result that would have been unthinkable two years ago. As the market digests the implications, the trajectory for staking derivatives — and the DeFi infrastructure that supports them — appears structurally sound, even as individual exchange security clearly is not.
