# sendCalls

Requests the wallet to sign and broadcast a batch of calls (transactions) to the network in a single operation.

```typescript
import { encodeFunctionData } from "viem";
import countContractAbi from "@/contract/counterABI.json";

const COUNTER_CONTRACT_ADDRESS = "0x4FbF9EE4B2AF774D4617eAb027ac2901a41a7b5F";

const txHash =  await smartAccountClient.sendCalls(
      {
        calls: [
          {
            to: COUNTER_CONTRACT_ADDRESS,
            value: 0,
            data: calldata,
          },
          {
            to: COUNTER_CONTRACT_ADDRESS,
            value: 0,
            data: calldata,
          },
        ],
      }
    )

```
