Usage

Installation

npm i @mylozzax/mylozzax-lws-client

Initialize

Initialize the Light Wallet Client.

const axios = require('axios').default
const LWSClient = require('@mylozzax/mylozzax-lws-client')
const options = {
    httpClient: axios,
    url: 'https://api.mylozzax.xyz',
    appName: 'MyLozzax',
    appVersion: '1.1.25'
}
const lwsClient = new LWSClient(options)

Login

Confirms if the the account is on the MyLozzax servers. if the create parameter is true it will add the wallet to the MyLozzax servers.

const address = '43zxvpcj5Xv9SEkNXbMCG7LPQStHMpFCQCmkmR4u5nzjWwq5Xkv5VmGgYEsHXg4ja2FGRD5wMWbBVMijDTqmmVqm93wHGkg'
const addAccount = true
const result = await lwsClient.login(
  privateViewKey,
  address,
  true
)
console.log(result)

Example Response

{
    "new_address": true,
    "start_height": 0
}

Get Addresses Transactions

Fetches all the transactions associated with the address. This includes decoys. The decoys can be removed by using the generateKeyImage function in the mylozzax-client repo.

const privateViewKey = '7bea1907940afdd480eff7c4bcadb478a0fbb626df9e3ed74ae801e18f53e104'

const result = await lwsClient.getAddressTxs(
  privateViewKey,
  address
)
console.log(result)

Fetch Addresses Unspent Outputs

Fetches all outputs available. They will need to be key imaged to work out which have been spent. This function also returns the fee per byte and fee mask for calculating the transaction fees.

Get Address info

Should no longer be used. Returns almost all the same info as the getAddressTxs call but included the exchange rates. The exchange rates can now be called via exchangeRates API call.

const privateViewKey = '7bea1907940afdd480eff7c4bcadb478a0fbb626df9e3ed74ae801e18f53e104'
const address = '43zxvpcj5Xv9SEkNXbMCG7LPQStHMpFCQCmkmR4u5nzjWwq5Xkv5VmGgYEsHXg4ja2FGRD5wMWbBVMijDTqmmVqm93wHGkg'
const result = await lwsClient.getAddressInfo(
  privateViewKey,
  address
)
console.log(result)
