Create a Token

The key which can perform token update and token delete operations on the token. The admin key has the authority to change the supply key, freeze key, pause key, wipe key, and KYC key. It can also update the treasury account of the token. If empty, the token can be perceived as immutable (not being able to be updated/deleted).

The key which can change the total supply of a token. This key is used to authorize token mint and burn transactions. If this is left empty, minting/burning tokens is not possible.

The key which can grant or revoke KYC of an account for the token's transactions. If empty, KYC is not required, and KYC grant or revoke operations are not possible.

The key which can wipe the token balance of an account. If empty, wipe is not possible.

The key which can sign to freeze or unfreeze an account for token transactions. If empty, freezing is not possible.

The key which can change the token's custom fee schedule. It must sign a TokenFeeScheduleUpdate transaction. A custom fee schedule token without a fee schedule key is immutable.

The key which has the authority to pause or unpause a token. Pausing a token prevents the token from participating in all transactions.

The metadataKey is essential for updating the metadata of a token on the Hedera network. According to Hedera's documentation, if this key is not set during the initial token creation process, it cannot be added later (This means that the ability to update the token's metadata must be established at the time of creation; otherwise, the metadata will remain unchangeable).
