You can only use this endpoint on the official Hyperliquid public API. It is not available through Chainstack, as the open-source node implementation does not support it yet. See Hyperliquid methods for the full availability breakdown.
This endpoint requires signature authentication. See our comprehensive Authentication via Signatures guide for implementation details.
The gossipPriorityBid action places a bid in the gossip priority auction to prioritize an IP address. Lower-indexed slots are strictly prioritized over higher ones. Use gossipPriorityAuctionStatus to read the current auction state.

Parameters

​
Required parameters

  • action (object, required) — The gossip-priority-bid action:
    • type (string) — Must be "gossipPriorityBid".
    • slotId (number) — Auction slot identifier (0 or 1). Lower-indexed slots are strictly prioritized.
    • ip (string) — The IP address (IPv4 or IPv6) to prioritize. Any address may bid on behalf of any IP.
    • maxGas (number) — Max gas in wei (1 HYPE = 10^8 wei) charged from the spot balance. The minimum auction price is 0.1 HYPE.
  • nonce (number, required) — Current timestamp in milliseconds.
  • signature (object, required) — EIP-712 signature of the action.

​
Optional parameters

  • expiresAfter (number, optional) — Timestamp in milliseconds after which the request is rejected.

​
Returns

Returns an object with the action status:
  • status — "ok" if the request was processed.
  • response — Contains operation details, with type "default".
