FIO Chain

Oracle monitors get_actions API on V1 History node

ERC20

Oracle monitors unwrap event for transfers
https://github.com/fioprotocol/fio.oracle/blob/3b1bfd3894e14b18e68f376b3a6bcfdb156c5f83/controller/api/fio.js#L21

Minimal validation
Confirms valid address
Logs errors to log file

Oracle does not monitor transactions after submitting
Rely on user reporting if transaction fails
Considering development of external transaction monitoring software / Admin UI

Manual setting of gas limit and gas price in env vars for each oracle
https://github.com/fioprotocol/fio.oracle/blob/3b1bfd3894e14b18e68f376b3a6bcfdb156c5f83/controller/api/eth.js#L34

Alien Teleport

Javascript
eosjs

UI-based approach to teleport wax tokens to your ETH or Binance wallet

WAX Chain

Listens to the EOSIO chain for teleport actions using a state history node
UI connects to Wax or Anchor wallet for signing transactions

ERC20

Monitors teleport events
Connects to Metamask for signing

Has a check-eth utility that reports on completion status

Need to confirm as it was broken when I tried it out: I think the user pays the ETH fees when they claim the teleport
