## Usage

```terminal
bun install @arcblock/did-ext
```

```javascript
const { WalletType } = require('@ocap/wallet');
const { fromAppDid } = require('@arcblock/did-ext');

const type = WalletType({ role: types.RoleType.ROLE_ACCOUNT });
const rootSk = '0x07abfceff5cdfb0cd164d2da98099c15b7223fc5a1b8c02c2cf1f74670c72aac27e1d28ed47cf4f2c4330a6e6e1dc0724721e80fa56177fdba926937a253fe7e';
let wallet = fromAppDid('', rootSk, type);
console.log(wallet.toJSON());
wallet = fromAppDid('zNKdqQxDUVz2YkfArfqc1CzjbX2QSNnMk1iW', rootSk, type);
console.log(wallet.toJSON());
```

```js
{
  type: {
    role: 'ROLE_ACCOUNT',
