import BitcoinRpcProvider from '@liquality/bitcoin-rpc-provider'
import EthereumRpcProvider from '@liquality/ethereum-rpc-provider'

import BitcoinLedgerProvider from '@liquality/bitcoin-ledger-provider'
import EthereumLedgerProvider from '@liquality/ethereum-ledger-provider'

import BitcoinNetworks from '@liquality/bitcoin-networks'
import EthereumNetworks from '@liquality/ethereum-networks'

const bitcoin = new Client()
const ethereum = new Client()

bitcoin.addProvider(new BitcoinRpcProvider(
  'https://liquality.io/bitcointestnetrpc/', 'bitcoin', 'local321'
))

  'https://rinkeby.infura.io/v3/xxx'
))

bitcoin.addProvider(new BitcoinLedgerProvider(

))

// Fetch addresses from Ledger wallet using a single-unified API
const [ bitcoinAddress ] = await bitcoin.wallet.getAddresses(0, 1)
const [ ethereumAddress ] = await ethereum.wallet.getAddresses(0, 1)

// Sign a message
const signedMessageBitcoin = await bitcoin.wallet.signMessage(
  'The Times 3 January 2009 Chancellor on brink of second bailout for banks', bitcoinAddress
)
const signedMessageEthereum = await ethereum.wallet.signMessage(
  'The Times 3 January 2009 Chancellor on brink of second bailout for banks', ethereumAddress
)

// Send a transaction
await bitcoin.chain.sendTransaction(<to>, 1000)
await ethereum.chain.sendTransaction(<to>, 1000)
