Hi
I used Remix to create an Nft Contract ErC721 on Polygon Mainnet. I did not include the Byte Code so am unable to Verify. Can I just start over. What happens to the existing contract?
The contract is operating successfully on Polygon Mainnet but i need verification!
I have deployed and verified other contracts on Mainnet with no Verification Problems.
Can I reproduce the BYTECODE without deploying a new contract?
Thanks in advance.
