useScaffoldContractWrite
Use this hook to send a transaction to your smart contract to write data or perform an action.
const { writeAsync, isLoading, isMining } = useScaffoldContractWrite({
contractName: "YourContract",
functionName: "setGreeting",
args: ["The value to set"],
// For payable functions, expressed in ETH
value: "0.01",
});
To send the transaction, you can call the writeAsync
function returned by the hook. Here's an example usage:
<button className="btn btn-primary" onClick={writeAsync}>
Send TX
</button>
This example sends a transaction to the YourContract
smart contract to call the setGreeting
function with the arguments passed in args
. The writeAsync
function sends the transaction to the smart contract, and the isLoading
and isMining
properties indicate whether the transaction is currently being processed by the network.
