For builders
List your app
A terminal, a Telegram bot or a perps agent on Hyperliquid. The protocol derives a builder address for your app, pays its 1 USDC activation and 100 USDC floor as the house's first check, and opens a 14-day raise in USDC on Solana.
What you get, what you give
You get the raise in five 20% tranches: the first when 10 distinct traders route fills through your code over 3 days, the next four at 2,000 USDC of routed notional per USDC of tranche. You keep 60% of your builder fees every week, on Hyperliquid. Your backers get 30%, and 10% buys and burns $SEED. You can stop using the code whenever you like, since your frontend builds the orders; what you leave behind is the unreleased escrow, and your backers' fees stop with your routing.
