bitcore-wallet-client-excc
Advanced tools
The official client library for [bitcore-wallet-service] (https://github.com/bitpay/bitcore-wallet-service).
This package communicates with BWS Bitcore wallet service using the REST API. All REST endpoints are wrapped as simple async methods. All relevant responses from BWS are checked independently by the peers, thus the importance of using this library when talking to a third party BWS instance.
See [Bitcore-wallet] (https://github.com/bitpay/bitcore-wallet) for a simple CLI wallet implementation that relays on BWS and uses bitcore-wallet-client.
You can start using bitcore-wallet-client in any of these two ways:
bower install bitcore-wallet-client from your consolenpm install bitcore-wallet-client from your console.Start your own local Bitcore wallet service instance. In this example we assume you have bitcore-wallet-service running on your localhost:3232.
Then create two files irene.js and tomas.js with the content below:
irene.js
var Client = require('bitcore-wallet-client');
var fs = require('fs');
var BWS_INSTANCE_URL = 'https://bws.bitpay.com/bws/api'
var client = new Client({
baseUrl: BWS_INSTANCE_URL,
verbose: false,
});
client.createWallet("My Wallet", "Irene", 2, 2, {network: 'testnet'}, function(err, secret) {
if (err) {
console.log('error: ',err);
return
};
// Handle err
console.log('Wallet Created. Share this secret with your copayers: ' + secret);
fs.writeFileSync('irene.dat', client.export());
});
tomas.js
var Client = require('bitcore-wallet-client');
var fs = require('fs');
var BWS_INSTANCE_URL = 'https://bws.bitpay.com/bws/api'
var secret = process.argv[2];
if (!secret) {
console.log('./tomas.js <Secret>')
process.exit(0);
}
var client = new Client({
baseUrl: BWS_INSTANCE_URL,
verbose: false,
});
client.joinWallet(secret, "Tomas", {}, function(err, wallet) {
if (err) {
console.log('error: ', err);
return
};
console.log('Joined ' + wallet.name + '!');
fs.writeFileSync('tomas.dat', client.export());
client.openWallet(function(err, ret) {
if (err) {
console.log('error: ', err);
return
};
console.log('\n\n** Wallet Info', ret); //TODO
console.log('\n\nCreating first address:', ret); //TODO
if (ret.wallet.status == 'complete') {
client.createAddress({}, function(err,addr){
if (err) {
console.log('error: ', err);
return;
};
console.log('\nReturn:', addr)
});
}
});
});
Install bitcore-wallet-client before start:
npm i bitcore-wallet-client
Create a new wallet with the first script:
$ node irene.js
info Generating new keys
Wallet Created. Share this secret with your copayers: JbTDjtUkvWS4c3mgAtJf4zKyRGzdQzZacfx2S7gRqPLcbeAWaSDEnazFJF6mKbzBvY1ZRwZCbvT
Join to this wallet with generated secret:
$ node tomas.js JbTDjtUkvWS4c3mgAtJf4zKyRGzdQzZacfx2S7gRqPLcbeAWaSDEnazFJF6mKbzBvY1ZRwZCbvT

Note that the scripts created two files named irene.dat and tomas.dat. With these files you can get status, generate addresses, create proposals, sign transactions, etc.

A simple logger that wraps the console.log methods when available.
Usage:
log = new Logger('copay');
log.setLevel('info');
log.debug('Message!'); // won't show
log.setLevel('debug');
log.debug('Message!', 1); // will show '[debug] copay: Message!, 1'
Sets the level of a logger. A level can be any bewteen: 'silent', 'debug', 'info', 'log', 'warn', 'error', and 'fatal'. That order matters: if a logger's level is set to 'warn', calling level.debug won't have any effect. If the level is set to 'silent', nothing will ever be logged. 'silent' is the default log level.
Parameters
level: number, the name of the logging level
Log messages at the debug level.
Parameters
args: *, the arguments to be logged.
Log messages at the info level.
Parameters
args: *, the arguments to be logged.
Log messages at an intermediary level called 'log'.
Parameters
args: *, the arguments to be logged.
Log messages at the warn level.
Parameters
args: *, the arguments to be logged.
Log messages at the error level.
