const API_KEY = "MYny3w7xJh6PRlRgkJ9604sHouY2MTke6lCPpSHq"
const DEST_ADDR = "0xd8da6bf26964af9d7eed9e03e53415d37aa96045"


async function main() {
  await configureEnvironment({
    apiKey: API_KEY
  })


  // Create an EOA from the currently connected browser wallet
  const provider = new ethers.providers.Web3Provider(window.ethereum, "any")
  await provider.send('eth_requestAccounts', [])
  const eoa = provider.getSigner()
  const auth = new Eoa({ signer: eoa })
  const uniqueId = auth.getUniqueId()


  // Get FunWallet associated with EOA
  const funWallet = new FunWallet( { uniqueId } )
