Hyperliquid Builder Fees Explained

Direct answer

Hyperliquid builder codes let application builders receive a fee on fills they send for a user after the user approves a maximum fee for that builder. Any future HypeBasis builder-code product must show the builder address, maximum fee, example cost, whether the fee is additional to protocol fees, and how to revoke approval before a user signs anything.

How builder fees work

• The user must approve a maximum builder fee for a builder address before orders can include that builder fee.
• The approval action must be signed by the user's main wallet, not an agent or API wallet.
• A future order can include a builder parameter with the builder address and the fee amount.
• The official docs describe the fee amount in tenths of basis points, so a value of 10 equals 1 basis point.
• Users can revoke builder-code permissions, and each user can have a limited number of active approvals.

Disclosure checklist

• Builder address shown before approval.
• Maximum approved builder fee shown before approval.
• Example cost shown on a representative trade size.
• Clear statement about whether the fee is additional to protocol fees.
• Revocation path explained before the user approves anything.
