New NFT smart contract about anone HOT 6 CLOSED

Currently, I have written a set of 1 package called an-std (for the purpose of providing a function to handle burning and distributing collection creation fees) and 3 contracts including anone-minter (for the purpose of creating collections for artists - this contract has been built successfully), an721 (which is the standard for NFT collection - this contract has also been built successfully) and anone-nft-marketplace (which is a contract for NFT trading: transfer NFT cw721 to the buyer and transfer cw20 token AN1 to the seller - this contract is not running properly logic yet). The old contract anone-cw721 is still used for the purpose of minting 1 nft to the function caller, for demo purposes only, and will soon be replaced by a production version.
I'll be writing a set of scripts soon to help you understand how contracts work.
