Wallet for Sui

Sui has implemented a wallet based on the Chrome browser extension called Sui Wallet browser extension. Additionally, Sui has developed a Wallet Adapter mechanism to facilitate interactions between DApps and wallets. Therefore, by implementing the relevant methods in this Adapter, it can be easily integrated into the Sui ecosystem, such as...

Below, we will take the official wallet as an example and list the usage methods.

Install

Create an account

Send Tokens

Receive Tokens

DApp integration of wallets

As mentioned above, the Wallet Adapter defines a set of methods for DApps to interact with wallets. Therefore, as a DApp, as long as you call wallet-related methods according to this specification, you can integrate with multiple wallets. For React projects, the official implementation of '@mysten/wallet-kit' provides some UI support.

Connect Wallet

Before connecting to a wallet, first check if the wallet is installed:

    import { useWalletKit, type WalletWithFeatures } from '@mysten/wallet-kit';

    type QredoConnectInput = {
        service: string;
        apiUrl: string;
        token: string;
        organization: string;
    };
    type QredoConnectFeature = {
        'qredo:connect': {
            version: '0.0.1';
            qredoConnect: (input: QredoConnectInput) => Promise<void>;
        };
    };
    type QredoConnectWallet = WalletWithFeatures<Partial<QredoConnectFeature>>;



    const { wallets } = useWalletKit();
    const selectedWallet = wallets.filter(
        (aWallet) =>
            'wallet' in aWallet && !!(aWallet.wallet as QredoConnectWallet).features['qredo:connect'],
    )[0];
    if (!selectedWallet || !('wallet' in selectedWallet)) {
        // no wallet installed
    }
If it is not installed, prompt the user to install it. If installed, show the Link button:

        <button
            onClick={async () => {
                try {
                    await qredoConnectWallet.features['qredo:connect']?.qredoConnect({
                        service: 'qredo-testing',
                        apiUrl: 'http://localhost:8080/connect/sui',
                        token: 'aToken',
                        organization: 'org1',
                    });
                } catch (e) {
                    console.log(e);
                }
            }}
        >
            Connect
        </button>

Sending your Message

When sending a transaction, first construct your transaction, and then call Adapter's signMessage method to sign it：

    import { ConnectButton, useWalletKit } from '@mysten/wallet-kit';

    const {
        currentWallet,
        currentAccount,
        signTransactionBlock,
        signAndExecuteTransactionBlock,
        signMessage,
    } = useWalletKit();

    <button
        onClick={async () => {
            console.log(
                await signMessage({
                    message: new TextEncoder().encode('Message to sign'),
                }),
            );
        }}
        >
                    Sign message
    </button>

Sign And Send Transaction

Sign And Send Transaction invoke signAndExecuteTransactionBlock method：

    import { ConnectButton, useWalletKit } from '@mysten/wallet-kit';

    const {
        currentWallet,
        currentAccount,
        signTransactionBlock,
        signAndExecuteTransactionBlock,
        signMessage,
    } = useWalletKit();

    <button
        onClick={async () => {
            const txb = new TransactionBlock();
            const [coin] = txb.splitCoins(txb.gas, [txb.pure(1)]);
            txb.transferObjects([coin], txb.pure(currentAccount!.address));

            console.log(
                await signAndExecuteTransactionBlock({
                    transactionBlock: txb,
                    options: { showEffects: true },
                }),
            );
        }}
        >
                    Sign And Send
    </button>
