ProviderKeeper
Overview
ProviderKeeper implements a Signature Provider for Signer protocol library.
Getting Started
Library installation
Install using npm:
npm install @waves/signer @waves/provider-keeper
or yarn
yarn add @waves/signer @waves/provider-keeper
Library initialization
Add library initialization to your app.
For Testnet:
import { Signer } from '@waves/signer'; import { ProviderKeeper } from '@waves/provider-keeper'; const signer = new Signer({ // Specify URL of the node on Testnet NODE_URL: 'https://nodes-testnet.wavesnodes.com', }); const keeper = new ProviderKeeper(); signer.setProvider(keeper);
For Mainnet:
import { Signer } from '@waves/signer'; import { ProviderKeeper } from '@waves/provider-keeper'; const signer = new Signer(); const keeper = new ProviderKeeper(); signer.setProvider(keeper);
You can also check if the Keeper Wallet is installed.
import { isKeeperInstalled } from '@waves/provider-keeper';
const isInstalled = await isKeeperInstalled();
if (!isInstalled) {
// Some logic in case KeeperWallet is not installed
}
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 and transfer funds:
const user = await signer.login();
const [transfer] = await signer
.transfer({
recipient: '3Myqjf1D44wR8Vko4Tr5CwSzRNo2Vg9S7u7',
amount: 100000, // equals to 0.001 WAVES
assetId: null, // equals to WAVES
})
.broadcast();
Or invoke some dApp:
const [invoke] = await signer
.invoke({
dApp: '3Fb641A9hWy63K18KsBJwns64McmdEATgJd',
fee: 1000000,
payment: [
{
assetId: '73pu8pHFNpj9tmWuYjqnZ962tXzJvLGX86dxjZxGYhoK',
amount: 7,
},
],
call: {
function: 'foo',
args: [
{ type: 'integer', value: 1 },
{ type: 'binary', value: 'base64:AAA=' },
{ type: 'string', value: 'foo' },
],
},
})
.broadcast();
