# Waves Signer

# Overview

Waves Signer is a TypeScript/JavaScript library that features signing and broadcasting transactions on behalf of users without asking them for their seed phrases or private keys.

The source code is available on Github: https://github.com/wavesplatform/signer (opens new window).

# Provider

In order to work with Signer, you need to link an external Provider library. Provider securely stores user's private data. Your web app and Signer itself do not have access to user's private key and seed phrase.

The Provider authenticates user and generates a digital signature.

Signer implements developer-friendly protocol for interacting with Provider as well as broadcasts transactions to the blockchain.

For now, you can use one of the following Providers:

You can also develop your own Provider, see the Provider Interface section below.

# Signer + ProviderWeb: How It Works

When Signer requests to sign a transaction, ProviderWeb opens an iframe (opens new window), where the user can review transaction details and confirm or reject it. Upon confirmation, ProviderWeb generates a digital signature. User experience is represented in the following video.

# Restrictions

Signer supports all types of transactions except Exchange transactions and Update Asset Info transactions.

Signer supports all browsers except Brave.

# Getting Started

# 1. Signer and Provider library installation

  • To install Signer library use

    npm i @waves/signer

  • To install ProviderKeeper, use

    npm i @waves/provider-keeper

    npm i @waves/provider-ledger

  • To install ProviderSeed, use

    npm i @waves/provider-seed @waves/waves-transactions

# 2. Library initialization

Add library initialization to your app.

  • For Testnet & ProviderKeeper:

    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'
});
signer.setProvider(new ProviderKeeper({data: 'website generated string'}));

  • For Testnet & Waves.Exchange ProviderCloud:

    import { Signer } from '@waves/signer';
import { ProviderCloud } from '@waves.exchange/provider-cloud';

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

  • For Testnet & Waves.Exchange ProviderWeb:

    import { Signer } from '@waves/signer';
import { ProviderWeb } from '@waves.exchange/provider-web';

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

  • For Testnet & ProviderLedger:

    import { Signer } from '@waves/signer';
import { ProviderLedger } from '@waves/provider-ledger';

const signer = new Signer({
  // Specify URL of the node on Testnet
  NODE_URL: 'https://nodes-testnet.wavesnodes.com'
});
signer.setProvider(new ProviderLedger({
  // Specify chain ID of Testnet
  wavesLedgerConfig: { networkCode: 84, },
}));

  • For Testnet & ProviderSeed:

    import { Signer } from '@waves/signer';
import { ProviderSeed } from '@waves/provider-seed';
import { libs } from '@waves/waves-transactions';

const seed = libs.crypto.randomSeed(15);
const signer = new Signer({
  // Specify URL of the node on Testnet
  NODE_URL: 'https://nodes-testnet.wavesnodes.com'
});
signer.setProvider(new ProviderSeed(seed));

  • For Mainnet & ProviderKeeper:

    import { Signer } from '@waves/signer';
import { ProviderKeeper } from '@waves/provider-keeper';

const signer = new Signer({
  // Specify URL of the node on Mainnet
  NODE_URL: 'https://nodes.wavesnodes.com'
});
signer.setProvider(new ProviderKeeper({data: 'website generated string'}));

  • For Mainnet & Waves.Exchange ProviderCloud:

    import { Signer } from '@waves/signer';
import { ProviderCloud} from '@waves.exchange/provider-cloud';

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

  • For Mainnet & Waves.Exchange ProviderWeb:

    import { Signer } from '@waves/signer';
import { ProviderWeb} from '@waves.exchange/provider-web';

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

  • For Mainnet & ProviderLedger:

    import { Signer } from '@waves/signer';
import { ProviderLedger } from '@waves/provider-ledger';

const signer = new Signer();
const provider = new ProviderLedger();
signer.setProvider(provider);

After that you will be able to use Signer features in the app.

# 3. Basic example

Now your application is ready to work with Waves blockchain. 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

# More examples

# Constructor

new Signer({
  NODE_URL: 'string',
})

Creates an object that features the following methods.

Parameters:

Parameter name Default value Description

# Create transactions

The following methods create transactions (but do not sign or broadcast them):

Check which of these transactions are supported by your Provider.

# Common fields

Each create transaction method has optional fields that you don't specify manually in most cases:

Field name Description Default value
chainId 'W'.charCodeAt(0) or 87 means Mainnet
'T'.charCodeAt(0) or 84 means Testnet		 Defined by configuration of Waves node that is set in Constructor
fee Transaction fee Calculated automatically as described in Transaction fee section
proofs Array of transaction signatures Added by sign or broadcast method (see How to Sign and Broadcast Transactions). If you specify a proof manually, it is also added to the array
senderPublicKey Base58 encoded public key of transaction sender Returned by login method

# How to Sign and Broadcast Transactions

Each create transaction method returns object that features the sign and broadcast methods.

To sign transaction use sign method. For example:

signer.invoke({
   dApp: address,
   call: { function: name, args: convertedArgs },
}).sign();

To sign transaction and immediately send it to blockchain use broadcast method. For example:

signer.invoke({
   dApp: address,
   call: { function: name, args: convertedArgs },
}).broadcast();

Note: this broadcast method has the same options as the signer.broadcast method that is described below.

You can sign or broadcast several transactions at once. For example:

signer.alias({ 'new_alias', })
  .data([{ key: 'value', type: 'integer', value: 1 ])
  .transfer({ recipient: '3P8pGyzZL9AUuFs9YRYPDV3vm73T48ptZxs', amount: 10000 })
