Glossary
A builder fee is a native Hyperliquid fee paid to the interface or system that routed a trade.
In short
Hyperliquid lets a builder charge a fee on volume it routes, capped by a maximum rate you approve from your wallet. HyperMirror charges 0.1% on mirrored notional volume and nothing else — no deposit, withdrawal, performance or idle-capital fees.
It is transparent and protocol-enforced: the ceiling you approve cannot be raised without a new signature from you.
Every fee model creates an incentive. A volume fee rewards turnover, so ask any provider using one how trade frequency and leader replacement are governed.
Methodology
Scoring and replacement are documented in full on How it works and in the Docs (Policy v3). In short: the Elite basket is sticky, emergencies remove a leader immediately, and soft issues accrue at most one strike per UTC day with three strike-days triggering replacement. Read how it works or the documentation for the full table.
Questions
