I have successfully deployed a new token contract on Etherscan Ropsten Network using metamask. I see my contract listed as "Unverified" so I followed the process given on https://ropsten.etherscan.io/verifyContract to get it verified but was unsuccessful with a message as follows:

CWF Verification

There are no changes done to the code. Kindly, suggest me what i'm missing here?

Other Information:

  • Contract Address: 0x0890fe640F27a74665E1Fdb5A0c532e154B7020e
  • Token Name: CWF Currency
  • Token Symbol: CWF

  • This feature compares the byte codes of the published smart contract and the one you uploaded for verification. Have you changed anything meanwhile?

  • Where exactly is this "Optimization Disabled" setting located? Somewhere on etherscan web site? Or in metamask?

If you haven't changed your source code, the only possible reason seems to be that Metamask and Etherscan use different compiler versions.

  • Yes, thank you for mentioning that. I corrected my mistake but didn't got any success until i disabled "Optimization". It's now resolved. :)
