I've successfully deployed once my own ERC20 token on Ropsten network with positive result. I can see the ERC20 token contract address associated to those correspondence accounts. But, when I try to change the token name and re-deploy to the ropsten network again, I coudn't see the new token details anymore. Did I miss any steps? Please see the attached screenshots below. CToken MToken

CToken - 0x0225b59b64aa51bd1cbf425896c70999c8c65565

MToken- 0x493d100661632C8e9d28F7144CCF046bA1a2E728

I thought is quite straight forward, I can just see the token on EtherScan upon successfully deployed.

Please advise

Etherscan shows your CToken and MToken (when viewing from the token URL). https://ropsten.etherscan.io/token/0x0225b59b64aa51bd1cbf425896c70999c8c65565 https://ropsten.etherscan.io/token/0x493d100661632C8e9d28F7144CCF046bA1a2E728

It may be that because MToken has no token transactions, Etherscan didn't identify it as an ERC20 token. I viewed from the token URL and it was picked up. I also added as a custom token into MetaMask.

If you are not already, you can use OpenZeppelin as the basis to create your tokens.
See the OpenZeppelin documentation for details: https://docs.openzeppelin.org/v2.3.0/tokens

If you have questions about OpenZeppelin you can also ask in the community forum

    May I know when I re-deploy the same ERC20 token contract, do I have to give a new name or I can just re-use the same name. In my opinion, it get a new hashed key eventually. – David Jul 19 '19 at 01:28
  • You can re-deploy the exact same contract and it will have a different public address. – abcoathup Jul 19 '19 at 04:10

    Got it! Thank you so much. – David Jul 20 '19 at 15:39
  • Quick one, I just re-deployed the same ERC20 CToken contract to the Ropsten network without changing anything. When I add the new instance of the CToken to my wallet account, it just doesn't appear. Wondering could it be due to the same token name? – David Jul 22 '19 at 04:21
  • You didn't specify which wallet you are using. e.g. MetaMask – abcoathup Jul 22 '19 at 21:35
  • @abcoathup-let me try on that. – David Jul 23 '19 at 02:45
