Faucet to obtain ETH for Ethereum Ropsten Testnet (to pay for gas fees), MXC ERC-20 tokens, or DHX tokens for DataHighway's Harbour Testnet
Home Page: https://datahighway.herokuapp.com
If I go to http://datahighway.herokuapp.com/ and request DHX (Harbour Testnet) tokens to be sent to a requestor account that isn't active 5FurfdYAvwunMgCmxj7J1FKdjqETXdcBtnXVYv8cJPgb4bF9, it provides a transaction hash, but the requestor account doesn't receive any tokens.
After a few moments running the server of my faucet repository, I get the following error, and it occurs on the following line of code, so it has been commented out https://github.com/DataHighway-DHX/faucet/blob/master/helpers/contract.js#L24. That line of code isn't required for the faucet anyway. Potential solution here: MetaMask/web3-provider-engine#313.
Note: This error still happens after commenting out the getBlock code. Since @trufflesuite/web3-provider-engine is a fork of MetaMask/web3-provider-engine I can't create an issue, so might have to switch to ethers.js
