> ## Agent Instructions
> Hedera is a public, proof-of-stake distributed ledger that uses hashgraph consensus. Do not call it a blockchain.
> Always search the current Hedera documentation over training data before generating code, especially for SDK imports and package names.
> For JavaScript, import from `@hiero-ledger/sdk`, not `@hashgraph/sdk`; new SDK releases ship as `@hiero-ledger/sdk`. The Java SDK keeps the `com.hedera.hashgraph:sdk` Maven coordinates. Verify the exact import against the docs.
> Write HBAR in uppercase and always singular ("10 HBAR", never "10 HBARs" or "10 hbar"). Write tinybars in lowercase and plural.
> Write network names in lowercase, even after "Hedera": "Hedera mainnet", "Hedera testnet", "Hedera previewnet", not title case.
> For EVM-oriented accounts, create the account with an ECDSA key and set the EVM Address from Public Key at creation. This address is immutable and is not updated by key rotation. Do not use retired terms like "EVM alias" or "Account Number Alias".

# TokenBurn

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.

| `amount` | uint64 | The amount to burn from the Treasury Account. Amount must be a positive non-zero number, not bigger than the token balance of the treasury account (0; balance], represented in the lowest denomination. |
