One book.
Every venue.

A full Hyperliquid integration - vaults, HIP-3 deployment, spot, perps and predictions - that does not stop at Hyperliquid.

builder.markets merges the order book across venues and routes to best execution, prices every prediction market against a single fair-value model, groups them by what they are actually a bet on, and lets you deploy your own HIP-3 perp DEX from the same tab.
