Burn Transaction

Burn transaction decreases the amount of token on sender's account and thereby the total amount of the token on the blockchain. Any account that owns a token (not necessarily the token issuer) can send the Burn transaction. Burned tokens cannot be restored back to the account.

Fee

The minimum fee for a Burn transaction is 0.001 WAVES, in case of burning a smart asset 0.005 WAVES.

If the transaction sender is a dApp or smart account, and the complexity of the account script or dApp script verifier function exceeds the sender complexity threshold, the minimum fee is increased by 0.004 WAVES. (Before activation of feature #16 “Ride V5, dApp-to-dApp invocations”, the extra fee of 0.004 WAVES was required regardless of the complexity of the account script or the presence and complexity of the dApp script verifier function.)
