Some extended examples

For these examples, assume you have the following data and functions available:

// a constant for my type.
const myType = `${packageId}::my_module::MyStruct<${packageId}::my_coin_module::MyCoin>`;
// a constant for another type.
const otherType = `${packageId}::other_module::OtherStruct<${packageId}::other_coin_module::OtherCoin>`;

// initialize a kioskClient.
const kioskClient = new KioskClient({
    client: new IotaClient({
        url: getFullnodeUrl(Network.Testnet),
    }),
    network: Network.Testnet,
});

Minting a MyCoin

This example demonstrates how to mint a MyCoin.

async function mintMyCoin(address: string) {
    const { kioskOwnerCaps } = await kioskClient.getOwnedKiosks({ address });

    // Choose the first kiosk for simplicity. We could have extra logic here (e.g. let the user choose, pick a personal one, etc).
    const cap = kioskOwnerCaps[0];

    const tx = new Transaction();
    const kioskTx = new KioskTransaction({ transaction: tx, kioskClient, cap });

    // We're mixing the logic here. If the cap is undefined, we create a new kiosk.
    if (!cap) kioskTx.create();

    // Let's mint a MyCoin here into the kiosk (either a new or an existing one).
    tx.moveCall({
        target: `${packageId}::my_module::mint_app::mint`,
        arguments: [kioskTx.getKiosk(), kioskTx.getKioskCap()],
        typeArguments: [myType],
    });

    // If we don't have a cap, that means we create a new kiosk for the user in this flow.
    if (!cap) kioskTx.shareAndTransferCap(address);

    kioskTx.finalize();

    // sign and execute transaction.
    await signAndExecuteTransaction({ tx });
}

Mixing two MyCoins

This example demonstrates how to use the Kiosk SDK to mix two MyCoins.

// We're mixing two coins.
async function mixMyCoins(firstCoinObjectId: string, secondCoinObjectId: string, cap: KioskOwnerCap) {
    const tx = new Transaction();
    const kioskTx = new KioskTransaction({ transaction: tx, kioskClient, cap });

    // borrow both coins.
    const [coin1, promise1] = kioskTx.borrow({
        itemType: myType,
        itemId: firstCoinObjectId.
    });

    const [coin2, promise2] = kioskTx.borrow({
        itemType: myType,
        itemId: secondCoinObjectId.
    });

    // Let's call the mix function. We skip any payment related stuff here.
    tx.moveCall({
        target: `${packageId}::mix_app::mix`,
        arguments: [
            coin1,
            coin2,
            kioskTx.getKiosk(),
            kioskTx.getKioskCap(),
        ]
        typeArguments: [myType],
    });

    kioskTx.return({
        itemType: myType,
        item: coin1,
        promise: promise1
    })
    .return({
        itemType: myType,
        item: coin2,
        promise: promise2
    }).finalize();

    // sign and execute transaction.
    await signAndExecuteTransaction({ tx });
}
