On-chain order book
A central limit order book with visible depth on both sides, backstopped by Uniswap v4 pools when the book thins. Every resting bid and offer is on-chain — no hidden internalisation.
01 — Perpetuals
A perpetual DEX,
settled on Ethereum.
Astro DEX Perpetual is a perpetual futures exchange on Ethereum: an on-chain order book backed by Uniswap v4 liquidity, up to 50x leverage, cross and isolated margin, and hourly funding — with an agent that can drive it for you.

Up to 50x leverage
Per-market leverage caps from 10x to 50x, adjustable per order. Initial and maintenance margin are computed live, so the liquidation price is visible before you sign.
Cross & isolated margin
Run one shared collateral pool across every position, or ring-fence a single market so a bad trade can only cost what you allocated to it.
Full order types
Market, limit, and scale ladders, plus reduce-only, post-only, take-profit and stop-loss attachments — the whole toolkit, not just a buy button.
Hourly funding
Funding settles every hour against a premium index, keeping the perp pinned to the oracle. Rates are shown per market, live, with the countdown to the next payment.
Liquidation engine
Positions are marked continuously against the oracle. Partial liquidations unwind the smallest amount that restores margin; an insurance fund backstops the remainder.
Maker-friendly fees
0.015% maker and 0.045% taker at base tier, scaling down with volume. Makers who add depth to a thin book earn a rebate instead of paying.
Agent-driven execution
Hand any strategy to the Astro agent: it reads the matrix, sizes inside your risk envelope, and routes the order — while you keep the keys and the kill switch.
