useSendCalls

function useSendCalls<TEntryPointVersion>(
  params,
): UseSendCallsResult<TEntryPointVersion>;

Defined in: account-kit/react/src/hooks/useSendCalls.ts:120

Hook for sending calls to a smart account or EOA wallet.

This hook provides functionality to execute calls on a smart account using Account Abstraction, or fall back to regular EOA transactions when connected to an EOA wallet. It handles the complete flow of preparing, signing, and sending calls.

<Note> If using this hook with an ERC-20 paymaster in pre-operation mode with autoPermit, the contents of the permit will be hidden from the user. It is recommended to use the usePrepareCalls hook instead to manually handle the permit signature. </Note>

Example

import { useSendCalls } from "@account-kit/react";
 
const { sendCalls, sendCallsAsync, isSendingCalls, error } = useSendCalls();
 
// Send a single call
await sendCallsAsync({
  calls: [
    {
      to: "0x...",
      data: "0x...",
      value: "0x0",
    },
  ],
});
 
// Send multiple calls (smart account only)
await sendCallsAsync({
  calls: [
    { to: "0x...", data: "0x..." },
    { to: "0x...", data: "0x..." },
  ],
});

Type Parameters

Parameters

Returns

UseSendCallsResult<TEntryPointVersion>

An object containing:

• sendCalls: Function to send calls synchronously (returns void)
• sendCallsAsync: Async function to send calls (returns Promise)
• sendCallsResult: The result of the last successful call execution
• isSendingCalls: Boolean indicating if calls are currently being sent
• error: Error from the last failed call execution, if any

Description

• When connected to an EOA wallet, only single calls are supported (batch execution is not allowed)
• For smart accounts, the returned ids are the prepared call IDs
• For EOA wallets, the returned ids are transaction hashes
