This was shared by the Aptos on their Twitter for minting just exactly a year after they launch their mainnet. Steps is below
Visit https://Graffio.art
Connect via Aptos wallet adaptor, or log in through social media
If logging in socially, create a Graffio Wallet
Add your art to our collective canvas
Return later to your wallet to view your NFT
Wait to receive you nft in the next 24hrs
Do this as it’s closing in less than 12hrs
I will personally recommend the use of martian wallet as it’s fast and easy
