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 stakingLinkDisableTradingUser action is sent by the staking user to permanently disable a linked trading user, locking its funds. After one year of locking, the trading user’s funds are automatically transferred to the staking user. This is a user-signed EIP-712 action.
This action is irreversible. It permanently disables the linked trading user and locks its funds.
