|
|
|
`@harmony-js/account` is dealing with account related features. |
|
|
|
|
This package provides a collection of apis to create accounts and wallets and sign using them. A wallet can hold multiple accounts and account is associated with a unique `one` address. This package also provides facilies to manage account keys. |
|
|
|
|
|
|
|
|
|
Developers can use this package to: |
|
|
|
|
- Create `Account` instance |
|
|
|
|
- Create `Wallet` instance |
|
|
|
|
- Sign `Transaction` |
|
|
|
|
- Convert address format |
|
|
|
|
- Manage `privateKey` or `mnemonic phrases` and do the `encrypt` and `decrypt` job |
|
|
|
|
## Installation |
|
|
|
|
|
|
|
|
|
There are 2 main classes in this package, `Account` and `Wallet`. |
|
|
|
|
|
|
|
|
|
- The `Account` class is basic instance that contains most features mentioned above. |
|
|
|
|
- The `Wallet` class is class that stores all `Account` instance, you can do CRUD on it. |
|
|
|

### Examples |
|
|
|
|
## Usage |
|
|
|
|
|
|
|
|
|
Create a random account |
|
|
|
|
Creating new account and display hex and bech32 (one) addresses
|
|
|
|
|
```javascript
|
|
|
|
|
// import the Account class
|
|
|
|
|
import {Account} from '@harmony-js/account' |
|
|
|
|
|
|
|
|
|
// Messenger is optional, by default, we have a defaultMessenger
|
|
|
|
|
// If you like to change, you will import related package here.
|
|
|
|
|
import { HttpProvider, Messenger } from '@harmony-js/network'; |
|
|
|
|
import { ChainType, ChainID } from '@harmony-js/utils'; |
|
|
|
|
|
|
|
|
|
// create a custom messenger
|
|
|
|
|
const customMessenger = new Messenger( |
|
|
|
|
new HttpProvider('http://localhost:9500'), |
|
|
|
|
ChainType.Harmony, // if you are connected to Harmony's blockchain
|
|
|
|
|
ChainID.HmyLocal, // check if the chainId is correct
|
|
|
|
|
) |
|
|
|
|
|
|
|
|
|
// to create an Account with random privateKey
|
|
|
|
|
// and you can setMessenger later
|
|
|
|
|
const randomAccount = new Account() |
|
|
|
|
randomAccount.setMessenger(customMessenger) |
|
|
|
|
|
|
|
|
|
// or you can set messenger on `new`
|
|
|
|
|
const randomAccountWithCustomMessenger = new Account(undefined, customMessenger) |
|
|
|
|
|
|
|
|
|
// you can display the account
|
|
|
|
|
console.log({randomAccount,randomAccountWithCustomMessenger}) |
|
|
|
|
|
|
|
|
|
// or you can use static method to create an Account
|
|
|
|
|
const staticCreatedAccount = Account.new() |
|
|
|
|
// but you have to set messenger manually after
|
|
|
|
|
staticCreatedAccount.setMessenger(customMessenger) |
|
|
|
|
|
|
|
|
|
console.log({staticCreatedAccount}) |
|
|
|
|
const account = new Account(); // or const account = Account.new()
|
|
|
|
|
console.log(account.checksumAddress); |

|
|
|
|
|
|
|
// NOTED: Key with or without `0x` are accepted, makes no different
|
|
|
|
|
// NOTED: DO NOT import `mnemonic phrase` using `Account` class, use `Wallet` instead
|
|
|
|
|
const myPrivateKey = '0xe19d05c5452598e24caad4a0d85a49146f7be089515c905ae6a19e8a578a6930' |

|
|
|
|
|
|
const myAccountWithMyPrivateKey = new Account(myPrivateKey) |
|
|
|
|
|
|
|
|
|
// you can also import privateKey use static method
|
|
|
|
|
const myAccountWithMyPrivateKeyUsingStatic = Account.add(myPrivateKey) |
|
|
|
|
|
|
|
|
|
console.log({ myAccountWithMyPrivateKey, myAccountWithMyPrivateKeyUsingStatic }) |
|
|
|
|
|
|
|
