Before your first trade, Agonaut asks for a one time approval. This is what
connects your trading to Agonaut so your volume earns points and rewards.
What you are approving
You approve a builder fee of 0.030% to Agonaut’s builder address on
Hyperliquid. This is a Hyperliquid native feature: a builder fee is a small,
capped fee that an app can collect on the volume it routes, and you approve the
maximum rate up front.
Open the trade page
The activation prompt appears the first time you trade, or on your account
page.
Sign the approval
Your wallet signs an approveBuilderFee message setting the cap at 0.030%.
This is a signature, not a transfer.
Trading is live
You can now place orders, and your volume counts toward points and the
leaderboard.
The fee is a cap, not a charge on signing. You are charged the 0.030% only on
actual trades, taken by Hyperliquid at fill time. Approving costs nothing.
Why a fee at all
That 0.030% is what funds the whole reward engine. The large majority of it
flows straight back to traders as competition prizes and referral payouts. See
Fees for where every basis point goes.
Optional: instant trading
After activating, you can enable an agent wallet so
that orders sign locally without a wallet popup on every action. It is one extra
signature, fully revocable, and it can never withdraw your funds.
