Custodial MarketPlace

Custodial Sale

The creator of a sale sends its NFT to the marketplace for custody. It ensures that the NFT cannot be sold or sent outside of the marketplace as long as the sale is not completed or cancelled.

• Implement IERC721Receiver and IERC1155Receiver to allow receiving NFTs for custody.

• The seller MUST send its NFT to the marketplace to create a sale order

• If the seller cancels the sale, the NFT is sent back to him.

• If an external user buys the sale, the NFT is sent from the marketplace contract directly to the buyer.
