I am planning to launch my own crypto tokens on polygon. But couldn’t understand the process properly of how to upload logo for the token. Also I don't think on testnet I can test it. Is there any easy way to set up your token logo before listing. Please help.

  • That has nothing to do with ethereum and the blockchain. Wallet providers and exchanges and are those who set and show icon to their coins

ERC20 tokens have optional metadata of name, symbol and decimals (for details see: https://eips.ethereum.org/EIPS/eip-20 558).

Token icons and any other metadata are not part of the specification. Each application/dapp may have a different way of setting this information.

For adding an icon to Etherscan, please see their guide:

Note you will need to verify contract address ownership first:
