const fab = new Fab("http://fab:test@localhost:3889", repoData)

const myToken = fab.contract("zeppelin-solidity/contracts/token/CappedToken.sol")

async function transfer(fromAddr, toAddr, amount) {
  const tx = await myToken.send("transfer", [toAddr, amount], {
    senderAddress: fromAddr,
  })

  console.log("transfer tx:", tx.txid)
  console.log(tx)

  await tx.confirm(3)
