MSafe Sui App Store

Background

Due to Sui blockchain version limitations, multisig account can't propose multiple transactions at the same time. It's needed to be create as transaction intention first and propose transaction 1 by 1 for vote & execution.

How to develop

$3

- Create your app folder under src/apps/ folder

$3

- Create your dapp intentions under src/apps/ folder

Here is an example for transaction intention, if your dapp have multiple transaction types, you need to define 1 by 1 for each type of transaction intention.

``typescript
export interface CoinTransferIntentionData {
recipient: string;
coinType: string;
amount: string;
}

export class CoinTransferIntention extends CoreBaseIntention {
txType: TransactionType.Assets;

txSubType: 'SendCoin';

constructor(public readonly data: CoinTransferIntentionData) {
super(data);
}

async build(input: { suiClient: SuiClient; account: WalletAccount }): Promise {
const { suiClient, account } = input;
return buildCoinTransferTxb(suiClient, this.data, account.address);
}

static fromData(data: CoinTransferIntentionData) {
return new CoinTransferIntention(data);
}
}
`

Each intention should have one data structure to store transaction information for future build.
This structure can be defined according to your own business logic, it can be any type of data, (should be JSON serializable)

Transaction intention implement mainly one API build(): Promise which will build Sui transaction block from your defined business data.

$3

- Create helper ts at src/apps//intention.ts

Here is an example of intention.ts file

`typescript
export type CoreIntention = CoinTransferIntention | ObjectTransferIntention;

export type CoreIntentionData = CoinTransferIntentionData | ObjectTransferIntentionData;

export class CoreHelper implements MSafeAppHelper {
application: string;

constructor() {
this.application = 'msafe-core';
}

deserialize(): CoreIntention {
throw new Error('MSafe core transaction intention should be build from API');
}

async build(input: {
intentionData: CoreIntentionData;
txType: TransactionType;
txSubType: string;
suiClient: SuiClient;
account: WalletAccount;
}): Promise {
const { suiClient, account } = input;
let intention: CoreIntention;
switch (input.txSubType) {
case 'coin-transfer':
intention = CoinTransferIntention.fromData(input.intentionData as CoinTransferIntentionData);
break;
case 'object-transfer':
intention = ObjectTransferIntention.fromData(input.intentionData as ObjectTransferIntentionData);
break;
default:
throw new Error('not implemented');
}
return intention.build({ suiClient, account });
}
}
`

The helper is responsible for convert a transaction block to your own transaction intention business data. this is call by SuiWallet standard API sui:signTransactionBlock feature.

- Create your test at test/.test.ts

You can follow be example to write test

`typescript
import { TransactionType } from '@msafe/iota-utils';

import { CoinTransferIntention, CoinTransferIntentionData } from '@/apps/msafe-core/coin-transfer';
import { appHelpers } from '@/index';

import { Account, Client } from './config';

describe('MSafe Core Wallet', () => {
it('Core transaction build', async () => {
const appHelper = appHelpers.getAppHelper('msafe-core');

expect(appHelper.application).toBe('msafe-core');

const res = await appHelper.build({
txType: TransactionType.Assets,
txSubType: 'coin-transfer',
suiClient: Client,
account: Account,
intentionData: {
amount: '1000',
coinType: '0x2::sui::SUI',
recipient: '123',
} as CoinTransferIntentionData,
});
expect(res.blockData.version).toBe(1);
expect(res.blockData.sender).toBe('0x0df172b18d30935ad68b2f9d6180e5adcf8edfd7df874852817002e6eccada66');
});

it('Test intention serialization', () => {
const intention = CoinTransferIntention.fromData({
recipient: 'a',
coinType: 'b',
amount: '100',
});

expect(intention.serialize()).toBe('{"amount":"100","coinType":"b","recipient":"a"}');
});
});
`

$3

- Add your app helper to file src/index.ts

`typescript
export const appHelpers = new MSafeApps([new CoreHelper(), ]);
`

$3

Once you finish development, you can create a PR to submit your changes.

Integrate MSafe wallet with your app

The last step is to integrate MSafe wallet with your application

- Run command yarn add @msafe/sui-wallet to add MSafe wallet package to your project
- Add below code to your application, basically it should be added to your main.tsx file

`typescript
import { MSafeWallet } from '@msafe/sui-wallet';
import { registerWallet } from '@mysten/wallet-standard';

registerWallet(new MSafeWallet(''));
``

Once the development mentioned above is complete, MSafe team will assist in verifying the integration. Feedback will be provided to your team upon completion of the verification process.
