Create and Save a Private Key

var privateKey = new bitcore.PrivateKey();

var exported = privateKey.toWIF();
// e.g. L3T1s1TYP9oyhHpXgkyLoJFGniEgkv2Jhi138d7R2yJ9F4QdDU2m
var imported = bitcore.PrivateKey.fromWIF(exported);
var hexa = privateKey.toString();
// e.g. 'b9de6e778fe92aa7edb69395556f843f1dce0448350112e14906efc2a80fa61a'

Create an Address

var address = privateKey.toAddress();

Create a Multisig Address

// Build a 2-of-3 address from public keys
var p2shAddress = new bitcore.Address([publicKey1, publicKey2, publicKey3], 2);

Request a Payment

var paymentInfo = {
  address: '1DNtTk4PUCGAdiNETAzQFWZiy2fCHtGnPx',
  amount: 120000 //satoshis
};
var uri = new bitcore.URI(paymentInfo).toString();

Create a Transaction

var transaction = new Transaction()
    .from(utxos)          // Feed information about what unspent outputs one can use
    .to(address, amount)  // Add an output with the given amount of satoshis
    .change(address)      // Sets up a change address where the rest of the funds will go
    .sign(privkeySet)     // Signs all the inputs it can

Connect to the Network

var peer = new Peer('5.9.85.34');

peer.on('inv', function(message) {
  // new inventory
});

peer.connect();

Generate a random address

var privateKey = new bitcore.PrivateKey();

var address = privateKey.toAddress();

Generate an address from a SHA256 hash

var value = new Buffer('correct horse battery staple');
var hash = bitcore.crypto.Hash.sha256(value);
var bn = bitcore.crypto.BN.fromBuffer(hash);

var address = new bitcore.PrivateKey(bn).toAddress();

Import an address via WIF

var wif = 'Kxr9tQED9H44gCmp6HAdmemAzU3n84H3dGkuWTKvE23JgHMW8gct';

var address = new bitcore.PrivateKey(wif).toAddress();

Create a Transaction

var privateKey = new bitcore.PrivateKey('L1uyy5qTuGrVXrmrsvHWHgVzW9kKdrp27wBC7Vs6nZDTF2BRUVwy');
var utxo = {
  "txId" : "115e8f72f39fad874cfab0deed11a80f24f967a84079fb56ddf53ea02e308986",
  "outputIndex" : 0,
  "address" : "17XBj6iFEsf8kzDMGQk5ghZipxX49VXuaV",
  "script" : "76a91447862fe165e6121af80d5dde1ecb478ed170565b88ac",
  "satoshis" : 50000
};

var transaction = new bitcore.Transaction()
  .from(utxo)
  .to('1Gokm82v6DmtwKEB8AiVhm82hyFSsEvBDK', 15000)
  .sign(privateKey);

Sign a Bitcoin message

var Message = require('bitcore-message');

var privateKey = new bitcore.PrivateKey('L23PpjkBQqpAF4vbMHNfTZAb3KFPBSawQ7KinFTzz7dxq6TZX8UA');
var message = new Message('This is an example of a signed message.');

var signature = message.sign(privateKey);

Verify a Bitcoin message

var Message = require('bitcore-message');

var address = '13Js7D3q4KvfSqgKN8LpNq57gcahrVc5JZ';
var signature = 'IBOvIfsAs/da1e36W8kw1cQOPqPVXCW5zJgNQ5kI8m57FycZXdeFmeyoIqJSREzE4W7vfDmdmPk0HokuJPvgPPE=';

var verified = new Message('This is an example of a signed message.').verify(address, signature);

Create an OP RETURN transaction

var privateKey = new bitcore.PrivateKey('L1uyy5qTuGrVXrmrsvHWHgVzW9kKdrp27wBC7Vs6nZDTF2BRUVwy');
var utxo = {
  "txId" : "115e8f72f39fad874cfab0deed11a80f24f967a84079fb56ddf53ea02e308986",

  "satoshis" : 50000
};

var transaction = new bitcore.Transaction()
    .from(utxo)
    .addData('bitcore rocks') // Add OP_RETURN data
    .sign(privateKey);

Create a 2-of-3 multisig P2SH address

var publicKeys = [
  '026477115981fe981a6918a6297d9803c4dc04f328f22041bedff886bbc2962e01',

];
var requiredSignatures = 2;

var address = new bitcore.Address(publicKeys, requiredSignatures);

Spend from a 2-of-2 multisig P2SH address

var privateKeys = [
  new bitcore.PrivateKey('91avARGdfge8E4tZfYLoxeJ5sGBdNJQH4kvjJoQFacbgwmaKkrx'),
  new bitcore.PrivateKey('91avARGdfge8E4tZfYLoxeJ5sGBdNJQH4kvjJoQFacbgww7vXtT')
];
var publicKeys = privateKeys.map(bitcore.PublicKey);
var address = new bitcore.Address(publicKeys, 2); // 2 of 2

var utxo = {
