Burning NFTs on Algorand
You can burn only the NFTs that were minted with the address of the manager account specified in the manager parameter in the minting call (see the MintNftExpressAlgorand, MintNftAlgorand, and MintNftAlgorandKMS schemas of the request body).
Burning NFTs on Tezos
You can burn only the NFTs if you are admin or minter of the contract
Signing a transaction
When burning an NFT, you are charged a fee for the transaction, and you must sign the transaction with the private key of the blockchain address from which the fee will be deducted.
Providing the private key in the API is not a secure way of signing transactions, because the private key can be stolen or exposed. Your private keys should never leave your security perimeter. You should use the private keys only for testing a solution you are building on the testnet of a blockchain.
For signing transactions on the mainnet, we strongly recommend that you use the Tatum Key Management System (KMS) and provide the signature ID instead of the private key in the API. Alternatively, you can use the Tatum JavaScript client.
