Hello Every Body
Do you have any beginning tutorials about ethereum
Edson Ayllon
Hey, I made a tutorial for communicating to Ethereum smart contracts with a React application. Let me know if there are any errors so I can push corrections. https://medium.com/fullstacked/connect-react-to-ethereum-b117986d56c1?source=friends_link&sk=a79689e52fad9fad02d7385c5b936a6e

@balajipachai "gas is the metric using which transactions on the ethereum blockchain are executed." whats the point of gas why isnt the fee just in ether. 1 transactoin = 0.0003 ether or whatever. whats the whole point of having gas and gas limit seems complicated for no reason

I am getting an error response from Metamask (which is intended), while I try a particular transaction. Currently, I am getting all the error info, which I don't want the user to see. Is there a way I could parse the info from the error below. I am using a try-catch mechanism to catch the Error. And the below response is stored in the err variable.

[object Object]
  "message": "VM Exception while processing transaction: revert Contract is Paused at the moment",
  "code": -32000,
  "data": {
    "0xe45338d91c0015eed4257858ad69b06b995f9b56ffced9a0f2015a369d59418c": {
      "error": "revert",
      "program_counter": 9721,
      "return": "0x08c379a000000000000000000000000000000000000000000000000000000000000000200000000000000000000000000000000000000000000000000000000000000020436f6e74726163742069732050617573656420617420746865206d6f6d656e74",
      "reason": "Contract is Paused at the moment"

The catch block:

} catch (err) {

I want to either get the message part or reason part.

I already tried multiple ways using JSON.parse(), JSON.stringify() and toString().

Any help is appreciated. Thank You in advance.

@newforkdelta No it's a one way process. You can get a key from a seed but not the reverse. But that's not an issue, just generate a new seed with an offline wallet or a hardware one, and send all your ether on an address generated with this seed and just forget about the first one once you are sure you will never use it again. But if you just created it I guess you don't have much history. Be sure to transfer tokens like ERC20 or else first before you empty the ethers from the account otherwise you won't be able to do it next as you won't be able to pay the fees.
