    // ----ACCOUTS----
    //  EOS public and private keys can be generated off the chain, but EOS users need to create a user
    //  name before they can operate on the chain. So activated users are needed to send on-chain transactions
    //  to new users in order to help them create accounts. By default users need to find Tripartite help.
    //  main net only:
    // eos.getAccountNamesFromPubKey(pubKeyTest2)
    //  main net only: (i.e. 'binancecleos'):
    // eos.getAccSystemStats(accBinance)
    //  account name must be less than 13 characters
    //  can only contain the following symbols: .12345abcdefghijklmnopqrstuvwxyz:
    //  default: bytes = 8192, stake_net_quantity = '10.0000 SYS', stake_cpu_quantity = '10.0000 SYS', transfer = 0:

    //  'accountName', ownerPubKey, activePubKey
    // eos.createSingleAccount('accountName', pubKeyTest, pubKeyTest)

    // ----TRANSACTIONS----
    // Transactions can be considered confirmed with 99.9% certainty after an average of 0.25 seconds from time of broadcast.
    // The EOS aBFT algorithm provides 100% confirmation of irreversibility within 1 second.
    //  sender, receiver, quantity in format: '50.0000 SYS' , memo, | + optional: sign = true, broadcast = true
    // eos.transfer(acc1, acc2, '4.0000 SYS', 'myMemo12', true, true)
    //  first creates an unsigned transaction, signs it and then broadcasts it. All separately. See logs()
    // eos.transferSignPushTransaction(acc1, acc2, '5.0000 SYS', 'myMemo2')
    //  just signs the transaction and returns it:
    //  args: tr, from, to, quantity, memo
    // eos.signTr(tr, acc1, acc2, quantity, memo) // trxData, privKeyTest
    //  insert return value from eos.transfer(..., signed = true, broadcast = false)
    //  returns signature. Args: (from, to, quantity, memo = '')
    // eos.getSignature(acc1, acc2, quantityTest, memo = 'myMemo7')
    //  insert eg.: return value from eos.transfer(..., signed = true, broadcast = false);
    // eos.pushTransaction(returnValueFromEos.transfer)
    //  transfers, signs and broadcasts the transaction separately:
    // eos.transferSignPushTransaction(acc1, acc2, '5.0000 SYS', 'myMemo2')
    //  accountName, (+ int allAboveBlockHeightX --> optional)
    // eos.getOutgoingTransactions(accBinance)
    //  perform transaction and add the id + block number as args
    //  note: example tr only visible when switching to main net
    // eos.getTransaction(exampleTrxMainNet, trBlockHeight) // sender: 'binancecleos' on main net
    // eos.isTransactionExecuted(exampleTrxMainNet, trBlockHeight)

    // ----CURRENCY----
    // eos.getCurrencyBalance(acc1) //  using EOS account name
    // works for tokens as well, see https://github.com/eoscafe/eos-airdrops
    // 'SYMBOL', 'eos.contractName'
    // eos.getCurrencyStats('IQ', 'everipediaiq') // IQ on main net
    //  amount in format '1000.0000 XYZ', receiver, memo:
    // eos.createToken('1000.0000 XXZX', acc1, 'new Token')

    // ----OTHER----
    //  converts '1.3000 EOS' --> 1.3, see floatRegex in eosj.js
    // console.log('tofloat: ', eos.toFloat('1.03002000'))
