DEX by DEX, part 1 — Drift: Hyperliquid's closest rival, and a $285M lesson
A venue-by-venue tour of how each DEX handles vaults and copy trading. We start with Drift — the only place besides Hyperliquid where you can truly follow a trader on-chain — and the $285M hack that taught the whole space a lesson.
This blog spends most of its time inside Hyperliquid. But "is anyone else doing this?" deserves a real answer, venue by venue. So I'm walking through the major decentralized exchanges one at a time, asking the same question of each: when you put money in, are you following a trader — or quietly becoming the house? We start with the one place that genuinely rivals Hyperliquid on the first answer: Drift.
The one true peer
Most perp DEXs, as the rest of this series will show, only let you be the house. Drift is the exception. On Solana, Drift Vaults let a manager trade and depositors ride along — the same "follow a real trader" model as a Hyperliquid user vault. Drift is the dominant perpetuals DEX on Solana, has hit $1B in daily volume, and runs strategy vaults plus an insurance-fund vault. If you want the Hyperliquid experience without leaving Solana, Drift is the closest thing there is.
How they actually differ
The engine. Hyperliquid runs on its own purpose-built blockchain, designed for one job: a real on-chain order book. Drift runs on Solana — fast and richly composable with the rest of Solana DeFi, but a general-purpose chain shared with everything else. A specialized venue vs. a thriving ecosystem.
The depth. Hyperliquid is the overall perp-DEX leader (~44% of sector volume, close to two-thirds of open interest); Drift leads Solana but is a fraction of Hyperliquid's size. More vaults, deeper liquidity, and the protocol-run HLP backstop live on Hyperliquid.
The frontier. Hyperliquid is moving to tokenized, programmable HyperEVM vaults; Drift's vaults are Solana smart contracts. Which brings us to the part nobody can skip.
The $285M lesson
On April 1, 2026, Drift suffered one of the year's largest hacks: attackers spent months building trust with the team, then used Solana's "durable nonces" to get security-council members to unknowingly pre-sign transactions that handed over admin control — and drained an estimated $285M from its vaults. The trades weren't the problem. The admin keys were.
This is the single most important thing a Drift depositor — or any vault depositor — should sit with. It's the exact risk this blog keeps flagging: a vault is only as safe as who controls its contract. It also sharpens the legacy-vs-smart-contract point. Hyperliquid's native vaults are enforced at the protocol level, not by a separate admin-controlled contract, so they're less exposed to this specific vector. But Hyperliquid's own future — programmable HyperEVM vaults — moves toward exactly the smart-contract model Drift runs. The lesson isn't "Solana bad." It's: as vaults become custom contracts everywhere, "who holds the keys, and is it audited" becomes the whole game (the security checklist applies on every chain).
The honest verdict
Drift is a legitimate, well-built rival — arguably the only on-chain venue offering true follow-a-trader vaults outside Hyperliquid, and the natural home if your world is Solana. Competition like this is good for everyone. But on the axes that matter most for vault depositors — liquidity depth, the breadth of trader vaults to choose from, and a backstop the size of HLP — Hyperliquid still leads, and its programmable-vault roadmap is pulling ahead. Just remember the April lesson on the way in: on Drift, on Hyperliquid's EVM, anywhere, the keys are the kingdom.
