Detect Kastle

Check whether the Kastle extension is installed:

if (window.kastle) {
  console.log('Kastle Wallet detected!');
} else {
  alert('Please install Kastle Wallet.');
}

Interact with Kastle

const network = "mainnet"
const kaspaWasm = initKaspaWasm() // your initialize function for Kaspa Wasm file

const rpc = new kaspaWasm.RpcClient({
    url: "wss://ws.kaspa.forbole.com/borsh",
    networkId: network,
});

await rpc.connect()

// Connect wallet and get address
const isSuccess = await kastle.connect(network)
const { address, publicKey } = await kastle.getAccount();

// Build send transaction
const { entries } = await rpc.getUtxosByAddresses([address]);
const pending = await kaspaWasm.createTransactions({
  entries,
  outputs: [
    {
      address: "kaspa:123...sac",
      amount: kaspaWasm.kaspaToSompi("1"),
    },
  ],
  priorityFee: kaspaWasm.kaspaToSompi("0.01"),
  changeAddress: address,
  networkId: network,
});
const transaction = pending.transactions[0];
const txJson = transaction.serializeToSafeJSON();

const txId = await kastle.signAndBroadcastTx(network, txJson);

await rpc.disconnect()
