# TokenMint

> TokenMintTransaction is the Hedera Token Service protobuf message used to mint additional fungible units or new NFTs for an HTS token.

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

The operation increases the Total Supply of the Token. The maximum total supply a token can have is `2^63-1`.

The amount provided must be in the lowest denomination possible.\
Example:Token A has 2 decimals. In order to mint `100` tokens, one must provide amount of 10000. In order to mint `100.55` tokens, one must provide amount of `10055`.

| `token`    | [TokenID](/reference/protobuf/basic-types/tokenid) | The token for which to mint tokens. If token does not exist, transaction results in INVALID\_TOKEN\_ID                                                                                                                                                                        |
| `amount`   | uint64                                             | Applicable to tokens of type `FUNGIBLE_COMMON`. The amount to mint to the Treasury Account. Amount must be a positive non-zero number represented in the lowest denomination of the token. The new supply must be lower than 2^63.                                            |
| `metadata` | repeated bytes                                     | Applicable to tokens of type `NON_FUNGIBLE_UNIQUE`. A list of metadata that are being created. Maximum allowed size of each metadata is 100 bytes. The metadata can be arbitrary, but we recommend developers to follow [HIP-10](https://hips.hedera.com/hip/hip-10)standard. |
