Explainer: What is Builder Fee? When talking about OneKey’s 0-Fee Perps campaign, the concept of Builder Fee naturally comes up. Simply put, when you trade Hyperliquid Perps through a wallet, third-party frontend App, or trading bot, you may need to pay not only the trading fees charged by Hyperliquid itself, but also an extra fee to the interface or tool you use to place the trade. That extra charge is called Builder Fee. For most apps, the Builder Fee ranges from 0.025% to 0.1%. For every additional 0.1% in fees, trading 10 million USDC means paying an extra $10,000 on top of Hyperliquid’s own trading fees. On OneKey Perps, however, this fee is permanently 0.
