FAQ

Where do I upload my image for the NFT?

Uploading an image directly on-chain or to the Martian backend is not enabled. This will be available as soon as Aptos moves to Mainnet. For now, you can upload your image to any cloud of your choice and get a shareable image URL.

After minting the NFT, the image on the wallet is broken

This happens when an incorrect image URL is provided for the NFT URL field. Make sure that your URL contains .png or .jpg or .jpeg or .gif or .svg. You should verify that your image is displaying correctly in the image preview box.

Is multi-language support available?

Multiple languages are not supported right now. You will need to upload all the NFT details using an English keyboard. We are working on this and will announce the completion of this in Discord.

Mint was successful but image is not showing on the wallet

Please check your wallet address in the explorer (https://explorer.devnet.aptos.dev/account/<address>) and/ or share it with us on our Discord. We’ll be happy to help you and clear any doubts. You can copy your address by clicking on the address displayed on the website.
