Hyperliquid Tests Priority Fee Rules With 10 HYPE Delegation Rule

Decentralized derivatives platform Hyperliquid has introduced revised order priority rules on its testnet, including a reported 10 HYPE delegation requirement for traders seeking faster order handling through its priority fee system. According to CryptoNews, the changes follow trader feedback and concern accounts that depend on low delays when placing, modifying, or canceling orders.

The testnet update introduces a minimum delegated balance of 10 HYPE for accounts seeking to use immediate-or-cancel (IOC) and add-liquidity-only (ALO) priority fees. At the market price of $78.98, the 10 tokens had a market value of $789.80. The platform's existing technical documentation notes that priority fees are charged from a user's undelegated staking balance, though the newly reported delegation threshold introduces a staking-related eligibility requirement.

Account and Transaction Restrictions

The proposed rules restrict mempool priority to accounts using Standard abstraction, which is the recommended option for market makers, high-volume automated users, and developers. Additionally, account activity outside cancellations, order placements, and modifications would reduce transaction priority until confirmation under HyperCore operations.

A separate provision lowers mempool priority for accounts directly submitting CoreWriter operations, which connect smart contracts running on HyperEVM with actions on HyperCore. Hyperliquid has not provided a complete list of CoreWriter activities that would trigger this priority treatment.

Execution Speed and Queue Position

Hyperliquid's official documentation separates read priority from write priority. For IOC orders, priority fees can reduce the time between order submission and processing by approximately 45 milliseconds for each basis point of priority fee, up to an eight-basis-point range. Cancellation requests retain priority over immediately executable orders.

ALO priority fees affect an order's position within a price-level queue during a continuous 400-millisecond eligibility period rather than providing faster mempool processing. The platform burns priority fees collected through the mechanism according to its technical documentation.
