useScaffoldMultiWriteContract

Use this hook to batch-write multiple transactions to your smart contract.

const { sendAsync } = useScaffoldMultiWriteContract({
  calls: [
    {
      contractName: "YourContract1",
      functionName: "setGreeting",
      args: ["Hello"],
    },
    {
      contractName: "YourContract2",
      functionName: "setCounter",
      args: [42],
    },
  ],
});

This example sends multiple transactions to the specified smart contracts to call the functions with the arguments passed in calls. The sendAsync function sends the transactions to the smart contracts.

Usage Example

const { sendAsync } = useScaffoldMultiWriteContract({
  calls: [
    {
      contractName: "YourContract1",
      functionName: "setGreeting",
      args: ["Hello"],
    },
    {
      contractName: "YourContract2",
      functionName: "setCounter",
      args: [42],
    },
  ],
});

<button
  className="btn btn-primary"
  onClick={async () => {
    try {
      await sendAsync();
    } catch (e) {
      console.error("Error sending transactions:", e);
    }
  }}
>
  Send Transactions
</button>;

This example demonstrates how to use the sendAsyncfunction to send multiple transactions to the specified smart contracts, calling the functions with the arguments passed in calls.

Configuration

Parameter	Type	Description
calls	Calldata[]	Array of configuration objects for the contract calls. Each object should contain contractName, functionName, and args. For special datatypes such as enums, you can pass in enum types from starknet.js
options (optional)	InvocationsDetails	Additional options for the transactions.

Call Object Configuration

Parameter	Type	Description
contractName	string	Name of the contract to write to.
functionName	string	Name of the function to call.
args (optional)	unknown[]	Array of arguments to pass to the function (if any). Types are inferred from the contract's function parameters.

You can also pass other arguments accepted by useSendTransaction#sendAsync from starknet-start.

Return Values

• sendAsync function sends the transaction(s) to the smart contract.
