# sendCalls

> Function to send a batch of transactions in a single call using the connected Abstract Global Wallet.

Viem’s [sendCalls](https://viem.sh/docs/actions/wallet/sendCalls) method following [EIP-5792](https://eips.ethereum.org/EIPS/eip-5792) can be used to sign and submit multiple transactions in a single call using the connected Abstract Global Wallet.

## Usage

<CodeGroup>
  ```tsx Example.tsx theme={null}
  import { useSendCalls } from "wagmi";
  import { encodeFunctionData, parseUnits } from "viem";
  import { useAbstractClient } from "@abstract-foundation/agw-react";

  export function SendCalls() {
    const { data: abstractClient } = useAbstractClient();
    const { sendCalls } = useSendCalls();

    return (
      <button
        onClick={() => {
          if (!abstractClient) return;

          sendCalls({
            calls: [
              // 1 - Approval
              {
                to: TOKEN_ADDRESS,
                data: encodeFunctionData({
                  abi: erc20Abi,
                  functionName: "approve",
                  args: [ROUTER_ADDRESS, parseUnits("100", 18)],
                }),
              },
              // 2 - Swap
              {
                to: ROUTER_ADDRESS,
                data: encodeFunctionData({
                  abi: routerAbi,
                  functionName: "swapExactTokensForETH",
                  args: [
                    parseUnits("100", 18),
                    BigInt(0),
                    [TOKEN_ADDRESS, WETH_ADDRESS],
                    abstractClient.account.address,
                    BigInt(Math.floor(Date.now() / 1000) + 60 * 20),
                  ],
                }),
              },
            ],
          });
        }}
      >
        Send Batch Calls
      </button>
    );
  }
  ```

  ```tsx config.ts theme={null}
  import { parseAbi } from "viem";

  export const ROUTER_ADDRESS = "0x07551c0Daf6fCD9bc2A398357E5C92C139724Ef3";
  export const TOKEN_ADDRESS = "0xdDD0Fb7535A71CD50E4B8735C0c620D6D85d80d5";
  export const WETH_ADDRESS = "0x9EDCde0257F2386Ce177C3a7FCdd97787F0D841d";
  export const PAYMASTER_ADDRESS = "0x5407B5040dec3D339A9247f3654E59EEccbb6391";

  export const routerAbi = parseAbi([
    "function swapExactTokensForETH(uint256,uint256,address[],address,uint256) external",
  ]);

  export const erc20Abi = parseAbi([
    "function approve(address,uint256) external",
  ]);
  ```

## Parameters

<ResponseField name="calls" type="Array<Call>">
  An array of calls. Each call can include the following fields:

  <Expandable title="Call Fields">
    <ResponseField name="to" type="Address" required>
      The recipient address of the call.
    </ResponseField>

    <ResponseField name="data" type="Hex | undefined" required>
      Contract code or a hashed method call with encoded args.
    </ResponseField>

    <ResponseField name="abi" type="Abi | undefined">
      Contract ABI used to encode function calls.
    </ResponseField>

    <ResponseField name="functionName" type="string | undefined">
      Name of the function to call in the provided `abi`.
    </ResponseField>

    <ResponseField name="args" type="unknown[] | undefined">
      Arguments to pass to `functionName`. Will be ABI-encoded into `data`.
    </ResponseField>

    <ResponseField name="dataSuffix" type="Hex | undefined">
      Additional data appended to the end of the calldata (e.g. a domain tag).
    </ResponseField>

    <ResponseField name="value" type="bigint | undefined">
      Value in wei sent with this call.
    </ResponseField>
  </Expandable>
</ResponseField>

<ResponseField name="atomicRequired" type="boolean | undefined">
  When `true`, the bundle executes atomically — if any call reverts, the whole
  bundle reverts.
</ResponseField>

<ResponseField name="capabilities" type="Capabilities | undefined">
  Advanced features to enable for the bundle (gas sponsorship, access lists,
  etc.).

  <Expandable title="Capabilities Object">
    <ResponseField name="paymaster" type="{ address: Address; data?: Hex } | undefined">
      Gas sponsorship via the specified Paymaster contract.
    </ResponseField>
  </Expandable>
</ResponseField>

## Returns

Returns a `Promise<Hex>` containing the bundle hash. Pass this hash to `wallet_getCallsStatus` to monitor execution status.
