}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.
vaultModify action updates a vault’s settings — whether it accepts deposits from followers and whether it always closes positions on withdrawal.
