Nightshade DEX

About Nightshade DEX

Nightshade DEX is an order-book exchange live on Midnight mainnet, Cardano's partner chain built for data protection. Instead of an automated market maker, Nightshade keeps a real order book: you can swap at the best price on the book, or place limit and stop orders at the price you choose, and your order rests on the book until it is filled or you cancel it.

Every transaction on Midnight carries a zero-knowledge proof, and with Nightshade those proofs are made on your own device, right in the browser, with no separate proof server to install. You can connect with the Lace wallet, or use the built-in passkey wallet, which opens with Face ID or Touch ID and keeps the wallet on your device.

Fees are simple: a 0.2% taker fee, no maker fee, and DUST pays the Midnight network fee. DUST is generated by holding NIGHT, so NIGHT holders from the Cardano side can cover their own network fees.

The order-book contracts are written in Compact, Midnight's smart-contract language. They are tested so that after every operation, what the contract holds of each token matches exactly what its pools, orders and fees account for. The site reads its data from Midnight's public indexer.

Nightshade DEX is built by the Nightshade DEX team. The documentation covers trading, wallets and fees in detail at docs.nightshade.finance, and news is posted on X at @NightshadeDEX.
