Hyperliquid Adjusts Trading Priority Mechanism, Some CoreWriter Users Will Be Downgraded

Odaily reports that Hyperliquid has announced adjustments to its write priority fees rules, with the changes now live on testnet, primarily affecting latency-sensitive trading users. The new rules include:

Mempool priority applies only to Standard abstraction;

Aside from cancellations, order placements, and order modifications, other HyperCore operations will cause the relevant account's operations to be downgraded before confirmation;

Users who have previously sent CoreWriter operations directly will have their mempool priority lowered;

Additionally, using IOC and ALO priority fees requires holding at least 10 HYPE in delegatable balance.
