After the online remix solidity compiler recently changed design, I can't figure out where I can find the contract's ABI? Does anyone know where it can be found in the new version? Or any other way where I can get it?

Here are instructions to find contract ABI using online remix solidity compiler.

  1. In the "Compile" tab, click on the "Details" button.

  • @Alper they changed it to the " ABI" section now on the modal. Commented Feb 25, 2018 at 0:06
  • Thanks, Is there any way to ignore white space on the ABI section? They used to have it on the previous version. @Miguel Mota

    @Alper you can copy the ABI JSON and run it through a JSON minifier Commented Feb 25, 2018 at 0:13
  • Got it. Ah additional work :) This also works tr -d ' \t\n\r\f' <abiFile.json >abiOutput.json @Miguel Mota

The correct answer is from Miguel Mota.

But because I don't have enought reputation to comment, I just wan't to add that one can easily minify the json abi with online minifier: https://www.webtoolkitonline.com/json-minifier.html
