Hyperliquid updates its official documentation to clarify the fee logic for result tokens in HIP-4.

CoinFeed reported on April 30th that the Hyperliquid team has updated its official documentation, clarifying the fee logic for outcome tokens in HIP-4. Key points include: free opening, with fees only incurred upon closing or settlement; coverage of six scenarios including minting (no fee), normal trading, burning, and settlement, with fee logic varying depending on the payer; aligned quote tokens enjoy a 20% reduction in taker fees and a 50% increase in order book rebates. The fee formula is now publicly available to developers. Previously, in March, Hyperliquid announced the launch of the HIP-4 testnet, planning to launch a one-day binary prediction market for BTC and HYPE.
