Overview

ProviderKeeper implements a Signature Provider for Signer protocol library.

Getting Started

Library installation

To install Signer and ProviderKeeper libraries use

npm i @turtlenetwork/signer @waves/provider-keeper

Library initialization

Add library initialization to your app.

• For Testnet:

  import { Signer } from '@turtlenetwork/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 authData = {
      data: 'server generated string',
  }
  const keeper = new ProviderKeeper(authData);
  signer.setProvider(keeper);

• For Mainnet:

  import { Signer } from '@turtlenetwork/signer';
  import { ProviderKeeper } from '@waves/provider-keeper';
  
  const signer = new Signer();
  const authData = {
      data: 'server generated string',
  }
  const keeper = new ProviderKeeper(authData);
  signer.setProvider(keeper);

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();
