Update a token

A transaction that updates the properties of an existing token. The admin key must sign this transaction to update any of the token properties. With one exception. All secondary keys can sign a transaction to change themselves. The admin key can update existing keys but cannot add new ones if they were not set during the creation of the token. If no value is given for a field, that field is left unchanged. If a TokenUpdateTx is performed we will keep returning TOKEN_IS_IMMUTABLE when it tries to change non-key properties or the expiry without an admin key.

Property
Description

Name

The new name of the token. The token name is specified as a string of UTF-8 characters in Unicode. UTF-8 encoding of this Unicode cannot contain the 0 byte (NUL). Is not required to be unique.

Symbol

The new symbol of the token. The token symbol is specified as a string of UTF-8 characters in Unicode. UTF-8 encoding of this Unicode cannot contain the 0 byte (NUL). Is not required to be unique.

Treasury Account

The new treasury account of the token. If the provided treasury account is not existing or deleted, the response will be INVALID_TREASURY_ACCOUNT_FOR_TOKEN. If successful, the Token balance held in the previous Treasury Account is transferred to the new one.

Admin Key

The new admin key of the token. If the token is immutable (no Admin Key was assigned during token creation), the transaction will resolve to TOKEN_IS_IMMUTABlE. Admin keys cannot update to add new keys that were not specified during the creation of the token.

KYC Key

The new KYC key of the token. If the token does not have currently a KYC key, the transaction will resolve to TOKEN_HAS_NO_KYC_KEY.

Freeze Key

The new freeze key of the token. If the token does not have currently a freeze key, the transaction will resolve to TOKEN_HAS_NO_FREEZE_KEY.

Fee Schedule Key

If set, the new key to use to update the token's custom fee schedule; if the token does not currently have this key, transaction will resolve to TOKEN_HAS_NO_FEE_SCHEDULE_KEY

Pause Key

Update the token's existing pause key. The pause key has the ability to pause or unpause a token.

Wipe Key

The new wipe key of the token. If the token does not have currently a wipe key, the transaction will resolve to TOKEN_HAS_NO_WIPE_KEY.

Supply Key

The new supply key of the token. If the token does not have currently a supply key, the transaction will resolve to TOKEN_HAS_NO_SUPPLY_KEY.

Expiration Time

The new expiry time of the token. Expiry can be updated even if the admin key is not set. If the provided expiry is earlier than the current token expiry, the transaction will resolve to INVALID_EXPIRATION_TIME. NOTE: The maximum expiration time is now + 8,000,001 seconds (approximately 92 days).

Auto Renew Account

The new account which will be automatically charged to renew the token's expiration, at autoRenewPeriod interval.

Auto Renew Period

The new interval at which the auto-renew account will be charged to extend the token's expiry. The default auto-renew period is 7,890,000 seconds. Currently, rent is not enforced for tokens so auto-renew payments will not be made. NOTE: The minimum period of time is approximately 30 days (2592000 seconds) and the maximum period of time is approximately 92 days (8000001 seconds). Any other value outside of this range will return the following error: AUTORENEW_DURATION_NOT_IN_RANGE.

Memo

Short publicly visible memo about the token. No guarantee of uniqueness. (100 characters max)

Metadata Key

The desired new metadata key for the token. This value can be null.

Metadata

The desired new metadata for the token. This value can be null. The admin key or metadata key can be used to update this property.

The sender pays the max_auto_associations fee and the rent for the first auto-renewal period for the association. This is in addition to the typical transfer fees. This ensures the receiver can receive the token without association and makes it a smoother transfer process

Transaction Signing Requirements

  • Admin key is required to sign to update any token properties. (except for the expiry and all low priority keys)

  • A secondary key can update itself. Meaning it can sign a transaction that changes itself.

    • Example: Wipe Key can sign a transaction that changes only the Wipe Key

  • Updating the admin key requires the new admin key to sign.

  • If a new treasury account is set, the new treasury key is required to sign.

  • The account that is paying for the transaction fee.
