import Ledger from "@rnssolution/color-ledger"
import Cosmos from "@lunie/cosmos-js"

const privateKey = Buffer.from(...)
const publicKey = Buffer.from(...)

// init cosmos sender
const cosmos = Cosmos(STARGATE_URL, ADDRESS)

// create message
const msg = cosmos
  .MsgSend({toAddress: 'color1abcd09876', amounts: [{ denom: 'color', amount: 10 }})

// create a signer from this local js signer library
const ledgerSigner = async (signMessage) => {
  const ledger = await Ledger().connect()
  const publicKey = await ledger.getPubKey()
  const signature = await ledger.sign(signMessage)

  return {
    signature,
    publicKey
