Create an account
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.
When creating a new account using the
AccountCreateTransaction()API you will need an existing account to pay for the associated transaction fee.Transaction Fees
Transaction Signing Requirements
- The account paying for the transaction fee is required to sign the transaction
Transaction Properties
Field | Description |
|---|---|
Key | The key for the new account. |
Initial Balance | The initial balance of the account was transferred from the operator account, in HBAR. |
Receiver Signature Required | If true, all the account keys must sign any transaction deposited into this account (in addition to all withdrawals). default: false |
Max Automatic Token Associations | Accounts can optionally automatically associate tokens to this account if this property is set. You do not need to associate a token prior to transferring it to this account. The max automatic token association is 1,000 token IDs. |
Staked ID | The staked ID is the node ID this account is staking to or the account ID of the account this account is staking to. An account can be staked to only one node or one account at a time. See HIP-406.
Note: Accounts cannot stake to contract accounts. This will fixed in a future release. |
Decline Rewards | Some accounts may stake to a node and decline to earn rewards. If set to true, the account will not receive staking rewards. The default value is false. See HIP-406. |
Memo | Set a note or description that should be recorded with the state of the account entity (maximum length of 100 characters). Anyone can view this memo on the network. |
Auto Renew Period | The period of time in which the account will auto-renew in seconds. The account is charged tinybars for every auto-renew period. Duration type is in seconds. For example, one hour would result in an input value of 3,600 seconds.
NOTE: This is fixed to approximately 3 months (7890000 seconds). Any other value will return the following error: AUTORENEW_DURATION_NOT_IN_RANGE. default: 2,592,000 seconds (DISABLED) |

Wallet software can allow the user to create an "account" instantly, for free, even without an internet connection. In this case, it will not create an actual account on Hedera. Instead, it will simply create a public/private key pair for the user. The software will then display this as an "account" with a zero balance, with a "long account ID". This long-form doesn't look like
0.0.123, but instead is an alias consisting of <shard>.<realm>.<bytes>, where the bytes is a base32url representation of the bytes of a serialized HAPI primitive Key, with the trailing = padding characters removed. For example, 0.0.CIQNOWUYAGBLCCVX2VF75U6JMQDTUDXBOLZ5VJRDEWXQEGTI64DVCGQ is the alias address of shard 0 realm 0 with the serialization of a HAPI Key for the ed25519 public key 0xd75a980182b10ab7d54bfed3c964073a0ee172f3daa62325af021a68f707511a.The account alias is immutable, cannot be modified, and it will continue to be associated with that account for as long as it exists. Still, if the account is deleted and removed from Hedera, the alias can be associated with a new account.
The account is officially registered with Hedera when HBARs, fungible or non-fungible tokens are initially deposited to the account alias. The fee to create the accounts is charged in the transaction fee of the transfer transaction used to send the token to the account alias. The account creation transaction is executed first to register the new account and following the transfer transaction to transfer the tokens to the new account.
The consensus timestamp for the create account transaction is one nanosecond before the transfer transaction. The parent transfer transaction and the child account create transaction share the same payer account and timestamp in the transaction ID except that the child transaction has an added nonce value. You will also notice the account and transaction memo set to
auto-created account indicating this account was created by using an account alias.You can return the new account ID in one of the following ways:
- Requesting the child records of the parent transfer transaction using the parent transfer transaction ID. The child transaction ID in the child transaction record will display a nonce value (
[email protected]/1). - Requesting the child receipts of the parent transfer transaction using the parent transfer transaction ID. The account ID field will be populated with the new account ID.
- Requesting the receipt or record of the account create transaction by using the transaction ID of the parent transfer transaction and setting the nonce value to 1
- Looking at the parent transfer transaction record transfer list for the account that has a transfer that equals the transfer value minus the transaction fee
Note: You cannot get the new account ID from the receipt of the transfer transaction like you would expect from a normal account to create a transaction that was not triggered by another transaction. You can use the alias in transfer transactions, account info, and balance queries. The feature will be enabled to support all other transactions and queries in a future release.
Follow the steps below to create an account using an account alias:
- Create an ED25519 or ECDSA (secp256k1) key pair
- The public key will be the account alias
- The private key of the key pair you created will be the private key associated with the new Hedera account that will be created in the following step
- Convert the public key (account alias) to a Hedera account ID format (0.0.publicKey)
- Use the
TransferTransactionand transfer HBARs, fungible, or your non-fungible token to the public key address in the Hedera account ID format- The transfer will trigger an
AccountCreateTransactionand create the Hedera account for you - Following the transaction that creates your account, the tokens will be transferred to that account
- Get the new Hedera account ID (0.0.accountNum) by requesting the child record, child receipt, or account info (see above)
