    I would like to ask, where can I obtain the said API Key for Etherscan Contract Verification in Remix IDE?

    I did provide the API Key as highlighted in Yellow Color but is Invalid API Key.

    What type of API Key in Remix IDE need? Any ideas?

    hi. I'm trying to compile chainlink oracle contract in remix. Suggested solidity version 0.4.24. But old ui does not allow me to select this version, new ui selects automatically. But when I click compile button nothing happens. Can someone guide me how to compile contracts in remix? I am new to this
    Liana Husikyan
    @LianaHus
    new ui selects automatically the version according to the version mentioned in pragma
    if you change it in your pragma it should work
    we are not supporting old ui

    pragma solidity 0.4.19;

//Our first contract is a faucet
contract Faucet{

    //Give out ether to anyone who asks
    function withdraw(uint withdraw_amount) public {
        //Limit withdrawal amount.
        require (withdraw_amount <= 100000000000000000);

        //send the moneys
        msg.sender.transfer(withdraw_amount);
    }

     function () public payable {}

}
    this is from Mastering Ethereum (Antonopoulos, Wood) Chap. 2
    I got it to compile, and deployed using Remix. I can sent ether to the contract, however when I try to withdraw by going to deployed contracts, entering "100000000000000000" and clicking with draw, I get a message in console saying 'transact to Faucet.withdraw pending ...' and nothing else happens. The book says it is supposed to raise a dialog in metaMask to approve the transaction, but nothing else happens. Any idea what is gong wrong? Thanks in advance!

    @LifeIsVeryEarthly_gitlab Maybe your transaction fee is too low. What network did you connect via Metamask?

    @LifeIsVeryEarthly_gitlab Have you selected 'Injected web3' and do you see your metamask address in address box?
    Obijah Greaux
    @LifeIsVeryEarthly_gitlab
    @Aniket-Engg injjected web3 is selected but where it says "account" i don't see my metamask address, and it wont let me add it either ...

    Liana Husikyan

    You should accept connection request from remix-ide in metamask. Have you done that?

    @LianaHus hello. I don't know if you meant me or the guy after me, but metamask says remix is connected and can access my account. Still no luck

    Hi, just had an issue where I lost some files on Remix.
    Had them for over a year, and then when I refreshed the page, they all seemed to disappear. Curious if there is a way to restore or recover?

    They all got replaced with these files:
