Hi @1113,

Welcome to the community :wave:

I was able to deploy the same token to Ropsten using Remix:
https://ropsten.etherscan.io/token/0x4ebcad543a5eb1938052734c5da733ff31316ae7

Checking the failed transaction, there wasn’t enough gas. Gas limit shows as 41,797.

The successful transaction had a gas limit of 1,039,756.

Can you give any more details on how this occurred?
There was an issue with Ropsten earlier this week since the Istanbul hard fork, Ropsten testnet post Istanbul

You may want to try a different testnet such as Rinkeby, Kovan or Goerli.

Hi @1113,

Were you able to deploy?
