The "structural risk" that hit Solana DeFi: The next issues highlighted by the Drift hacking

A massive hacking incident occurred in the Solana-based DeFi protocol "Drift." With estimated losses of up to $280 million (approximately 43 billion yen), the scale alone indicates a significant impact on the market. This incident provides a good opportunity to examine both the structural risks inherent in DeFi and its evolving direction.

First, let's clarify the facts. On April 1, 2026, an unusual outflow of funds was detected in the Solana-based perpetual trading platform, Drift. The estimated loss is at least $200 million, with some estimates suggesting it could reach up to $270 million. Approximately $150 million worth of JLP tokens were stolen in a single transaction, along with multiple other assets including SOL, USDC, and BTC-related assets (various wrapped tokens).

The attackers converted the stolen assets into USDC using the DEX aggregator Jupiter, bridged it to Ethereum, and then converted it to ETH. Large-scale ETH holdings have already been confirmed. The attack design, spanning multiple vaults, and the speed of fund transfers using cross-chain technology, are symbolic of the current DeFi environment.

Similar to previous incidents in the cryptocurrency space, this incident exposed the "vulnerability of complex financial designs." In recent years, DeFi has moved beyond simple token swaps, becoming a "pseudo-hedge fund" combining delta-neutral strategies, staking, and leverage structures. While the structures for generating returns have become sophisticated, the underlying risks have become harder to see. Even seemingly rational complex designs can quickly malfunction under extreme circumstances. As the USDX depegg incident demonstrated, the complexity of the design often amplifies liquidity crises.

Furthermore, a distinctive feature of this incident was the "cross-chain-based attack." Assets were instantly moved to different chains, dramatically increasing the difficulty of tracking and freezing them. This is the flip side of convenience, and a side effect of DeFi beginning to function as a global financial system.
