# TokenBurn

> TokenBurnTransaction is the Hedera Token Service protobuf message used to burn fungible token units or NFTs from the HTS treasury.

Burns tokens from the Token's treasury Account. If no Supply Key is defined, the transaction will resolve to `TOKEN_HAS_NO_SUPPLY_KEY`.

The operation decreases the Total Supply of the Token. Total supply cannot go below zero.

The amount provided must be in the lowest denomination possible. Example:

Token A has 2 decimals. In order to burn 100 tokens, one must provide amount of 10000. In order to burn 100.55 tokens, one must provide amount of 10055.
