# 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, the minimum fee is increased by 0.004 WAVES.
