Create an account

Create an account using the account create API

A transaction that creates a Hedera account. A Hedera account is required to interact with any of the Hedera network services as you need an account to pay for all associated transaction/query fees. You can visit the Hedera Developer Portal to create a previewnet or testnet account. You can also use third-party wallets to generate free mainnet accounts. To process an account create transaction, you will need an existing account to pay for the transaction fee. To obtain the new account ID, request the receipt of the transaction.

{% hint style="info" %} When creating a new account using theAccountCreateTransaction()API you will need an existing account to pay for the associated transaction fee. {% endhint %}

Account Properties

{% content-ref url="../../../core-concepts/accounts/account-properties.md" %} account-properties.md {% endcontent-ref %}

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 your transaction fee cost.

Transaction Signing Requirements

• The account paying for the transaction fee is required to sign the transaction.

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 Value	Description
0	Automatic token associations or token airdrops 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.

{% hint style="info" %} 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. {% endhint %}

Account Alias

If an alias is set during account creation, it becomes immutable, meaning it cannot be changed. If you plan to update or rotate keys in the future, do not set the alias at the time of initial account creation. The alias can be set after finalizing all key updates. {% endhint %}
