You can burn a token that you currently own in one of two ways.
Manifold contracts support both Dead Burn and True Burn
Methods to Burn a Token:
1. Dead Burn:
This method involves sending the token to the address "0x0000…dEaD" which is an unrecoverable address that no one controls. It effectively removes the token from circulation.
Marketplaces typically adjust their token supply counts to reflect tokens sent to this dead address. However, even though the token is burned, details such as the token's, tokenId, owneraddress, and metadata remain intact within the contract, with the owner's address showing as "0x0000…dEaD."
How to burn a token by sending it to the dead address 0x0000…dEaD:
View the token on OpenSea with the wallet that owns the token
Transfer the token to the dead address: 0x000000000000000000000000000000000000dEaD
Submit the transaction
2. True Burn:
The true burn method is more final as it not only takes the token out of circulation but also erases its data from the contract. The token's historical records stay on the blockchain, but queries to the contract will act as if the token never existed. Consequently, details such as tokenId, owner's address, and metadata will be expunged from the contract's records.
How to true burn a token:
Visit the contract on etherscan
Write as Proxy
Connect with the address that owns the token
Burn function
Input the token id
Submit the transaction
