I have an ERC721 contract on Base called “Custom BBN by ViHa”. It was created via Manifold in June 2024. I tried to create a new 1/1 on that contract earlier today. At the last step, I’m being prompted to switch to Ethereum mainnet to publish the token.
This was my flow: sign in with wallet > login signature > click on the Base contract > Drafts > choose the recipient wallet address > PROMPT TO SWITCH TO MAINNET
