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.
Sends assets from Hyperliquid L1 to a HyperEVM address with optional calldata. Enables programmatic interactions between L1 and HyperEVM.

​
Parameters

​
Required parameters

  • action (object, required) — The action object containing:
    • type (string) — Must be "sendToEvmWithData"
    • destination (string) — EVM recipient address
    • token (string) — Token to send
    • amount (string) — Amount to send
    • data (string) — Optional calldata for the EVM transaction
  • nonce (number, required) — Current timestamp in milliseconds (must be recent)
  • signature (object, required) — EIP-712 signature of the action

​
Optional parameters

  • vaultAddress (string, optional) — Address when trading on behalf of a vault or subaccount

​
Returns

Returns an object with the action status:
  • status — "ok" if request processed
  • response — Contains action result data

​
