Update an account

A transaction that updates the properties of an existing account. The network will store the latest updates on the account. If you would like to retrieve the state of an account in the past, you can query a mirror node.

Transaction Fees

  • The sender pays for the token association fee and the rent for the first auto-renewal period.

  • Please see the transaction and query fees table for the base transaction fee.

  • Please use the Hedera fee estimator to estimate the cost of your transaction fee.

Transaction Signing Requirements

  • The account key(s) are required to sign the transaction.

  • If you are updating the keys on the account, the OLD KEY and NEW KEY must sign.

    • If either is a key list, the key list keys are all required to sign.

    • If either is a threshold key, the threshold value is required to sign.

  • If you do not have the required signatures, the network will throw an INVALID_SIGNATURE error.

Maximum Auto-Associations and Fees

Accounts have a property, maxAutoAssociations, and the property's value determines the maximum number of automatic token associations allowed.

Property ValueDescription

0

Automatic token associations or are not allowed, and the account must be manually associated with a token. This also applies if the value is less than or equal to usedAutoAssociations.

-1

The number of automatic token associations an account can have is unlimited. -1 is the default value for new automatically-created accounts.

> 0

If the value is a positive number (number greater than 0), the number of automatic token associations an account can have is limited to that number.

The sender pays the maxAutoAssociations 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 tokens without association and makes it a smoother transfer process.
