How to use the @liquality/client function in @liquality/client

function createERC20Client (asset, wallet) {
  const assetConfig = config.assets[asset]
  const erc20Client = new Client()
  erc20Client.addProvider(new EthereumRpcProvider(
    assetConfig.rpc.url
  ))
  if (wallet === 'metamask') {
    erc20Client.addProvider(new EthereumMetaMaskProvider(web3.currentProvider, EthereumNetworks[assetConfig.network]))
  } else if (wallet === 'ethereum_ledger') {
    erc20Client.addProvider(new EthereumLedgerProvider({network: EthereumNetworks[assetConfig.network]}))
  }
  erc20Client.addProvider(new EthereumErc20Provider(assetConfig.contractAddress))
  erc20Client.addProvider(new EthereumErc20SwapProvider())
  return erc20Client
}

function createEthClient (asset, wallet) {
  const ethConfig = config.assets.eth
  const ethClient = new Client()
  ethClient.addProvider(new EthereumRpcProvider(
    ethConfig.rpc.url
  ))
  if (wallet === 'metamask') {
    ethClient.addProvider(new EthereumMetaMaskProvider(web3.currentProvider, EthereumNetworks[ethConfig.network]))
  } else if (wallet === 'ethereum_ledger') {
    ethClient.addProvider(new EthereumLedgerProvider({network: EthereumNetworks[ethConfig.network]}))
  }
  ethClient.addProvider(new EthereumSwapProvider())
  return ethClient
}

function createBtcClient (asset, wallet) {
  const btcConfig = config.assets.btc

  const btcClient = new Client()
  if (wallet && wallet.includes('bitcoin_ledger')) {
    let addressType
    if (wallet === 'bitcoin_ledger_legacy') {
      addressType = 'legacy'
    } else if (wallet === 'bitcoin_ledger_nagive_segwit') {
      addressType = 'bech32'
    }
    const ledger = new BitcoinLedgerProvider({network: BitcoinNetworks[btcConfig.network]}, addressType)

    if (window.useWebBle || localStorage.useWebBle) {
      ledger.useWebBle()
    }
    btcClient.addProvider(getBitcoinDataProvider(btcConfig))
    btcClient.addProvider(ledger)
    btcClient.addProvider(new BitcoinSwapProvider({network: BitcoinNetworks[btcConfig.network]}, btcConfig.swapMode))
  } else if (wallet === 'bitcoin_node') {
