How do I delete or burn my NFTs?
You can delete NFTs by sending them to the Ethereum burn address. The Ethereum address: 0x000000000000000000000000000000000000dEaD is essentially a black hole for lots of NFTs and currencies. Transferring them to this address will cost some ether. NFTs cannot be deleted from the blockchain but you can remove them from being sold on Mintable.
Click on "Transfer" and wait for the transaction to be confirmed on the blockchain and you are done!
