Builder Codes
Extended Builder Codes documentation for alternative frontends, builder IDs, per-order builder fees, fee limits, referral compatibility and API integrations.
Builder Code Logic
Builder Codes let developers route Extended orders through alternative interfaces and attach a per-order builder fee. A builder uses an Extended account identifier together with the permitted fee rate when submitting orders.
Fee Handling
Builder fees are transferred to the builder account according to the protocol’s settlement schedule. The maximum allowed rate is exposed through the fee model, so integrations should validate limits rather than hard-code assumptions.
Referrals and Builders
Builder routing is compatible with referral relationships. Users can retain their referral association while trading through a builder integration, and eligible builders may also operate referral or affiliate codes under the relevant program rules.
