Overview

​ ProviderKEWallet is forked from ProviderWeb developed by Waves.Exchange implements a Signature Provider for Signer protocol library. Signer enables easy deploy dApps based on Waves blockchain. Users' encrypted private keys and SEED phrase are stored in ke.wallet domain of the local browser storage. KE.Wallet and other apps do not have access to the local data as they are stored encrypted.

​

For now, signing is implemented for all types of transactions except exchange transactions. ​

Getting Started

​

1. Library installation

​ To install Signer and ProviderKEWallet libraries use ​

npm i @waves/signer @ke.wallet/provider-ke-wallet

​ For Windows, use the following format:

npm i @waves/signer '@ke.wallet/provider-ke-wallet'

​ ​

2. Library initialization

​ Add library initialization to your app. ​

• For Testnet: ​

  import Signer from '@waves/signer';
  import { ProviderKEWallet } from '@ke.wallet/provider-ke-wallet';

const signer = new Signer({ // Specify URL of the node on Testnet NODE_URL: 'https://nodes-testnet.wavesnodes.com' }); signer.setProvider(new ProviderKEWallet('https://testnet.ke.wallet/signer'));

​
* For Mainnet:
​
```js
import Signer from '@waves/signer';
import { ProviderKEWallet } from '@ke.wallet/provider-ke-wallet';

const signer = new Signer();
signer.setProvider(new ProviderKEWallet());

​

3. Basic example

​ Now your application is ready to work with Waves Platform. Let's test it by implementing basic functionality. For example, we could try to authenticate user, get his/her balances and transfer funds. ​

const user = await signer.login();
const balances = await signer.getBalance();
const [broadcastedTransfer] = await signer
  .transfer({amount: 100000000, recipient: 'alias:T:merry'}) // Transfer 1 WAVES to alias merry
  .broadcast(); // Promise will resolved after user sign and node response
​
const [signedTransfer] = await signer
  .transfer({amount: 100000000, recipient: 'alias:T:merry'}) // Transfer 1 WAVES to alias merry
  .sign(); // Promise will resolved after user sign

​

Constructor

​

new ProviderKEWallet(clientOrigin: string, logs: boolean);

​ Creates an object that features user authentication and transaction signing. ​ You can use optional parameters for debugging. ​ | Parameter | Default value | Description | | :--- | :--- | :--- | | clientOrigin | https://ke.wallet/signer | URL of the ProviderKEWallet instance.
