There is one more thing I would like to know.

Is this possible?

・Ethereum Blockchain  
・Sell at openensea  
・Mint is lazymint  
・Save to on-chain（fully on-chain）

.

（flow）

・Save files to ipfs://  
meta+svg（base64) (I make this one)

・Purchaser buys at opensea

・Minted

・Save to on-chain

Is this possible or impossible?

If you could let me know.
