The total size for a given transaction is limited to 6KiB.
| Field | Description |
|---|---|
| Transaction ID | Set the ID for this transaction. The transaction ID includes the operator’s account (the account paying the transaction fee). If two transactions have the same transaction ID, they won’t both have an effect. One will complete normally and the other will fail with a duplicate transaction status. Normally, you should not use this method. Just before a transaction is executed, a transaction ID will be generated from the operator on the client. |
| Valid Duration | Set the duration that this transaction is valid for. Max network valid duration is 180 seconds. SDK default value is 120 seconds. The minimum valid duration period is 15 seconds. |
| Memo | Set a note or description that should be recorded in the transaction record (maximum length of 100 characters). Anyone can view this memo on the network. |
| Node ID | Set the account ID of the node that this transaction will be submitted to. |
| Max transaction fee | Set the max transaction fee the operator (transaction fee payer account) is willing to pay. Default: 2 hbar. |
| High Volume | If set to true, opts this transaction into the high-volume throttle system with variable-rate pricing for entity creation. Only affects supported transaction types; otherwise ignored. Default: false. See HIP-1313. |
The SDKs do not require you to set these fields when submitting a transaction to a Hedera network. All methods below are optional and can be used to modify any fields.
| Method | Type |
|---|---|
setTransactionID(<transactionId>) | TransactionID |
setTransactionValidDuration(<validDuration>) | Duration |
setTransactionMemo(<memo>) | String |
setNodeAccountIds(<nodeAccountIds>) | List<AccountId> |
setMaxTransactionFee(<maxTransactionFee>) | Hbar |
setGrpcDeadline(<grpcDeadline>) | Duration |
setRegenerateTransactionId(<regenerateTransactionId>) | boolean |
setHighVolume(<highVolume>) | boolean |
The example below uses
setKeyWithAlias() to set the EVM Address from Public Key at account creation, the recommended pattern for EVM compatibility. See Create an Account for details, including the immutability behavior and when to use setKeyWithoutAlias() instead.//Create the transaction and set the transaction properties
Transaction transaction = new AccountCreateTransaction() //Any transaction can be applied here
// Sets the EVM Address from Public Key (recommended for EVM compatibility)
.setKeyWithAlias(ecdsaPublicKey)
// Use .setKeyWithoutAlias(ecdsaPublicKey) if you plan to rotate keys soon after creation
.setInitialBalance(new Hbar(1))
.setMaxTransactionFee(new Hbar(2)) //Set the max transaction fee to 2 hbar
.setTransactionMemo("Transaction memo"); //Set the node ID to submit the transaction to
//v2.0.0
//Create the transaction and set the transaction properties
const transaction = await new AccountCreateTransaction() //Any transaction can be applied here
// Sets the EVM Address from Public Key (recommended for EVM compatibility)
.setKeyWithAlias(ecdsaPublicKey)
// Use .setKeyWithoutAlias(ecdsaPublicKey) if you plan to rotate keys soon after creation
.setInitialBalance(new Hbar(1))
.setMaxTransactionFee(new Hbar(2)) //Set the max transaction fee to 2 hbar
.setTransactionMemo("Transaction memo"); //Set the node ID to submit the transaction to
//Create the transaction and set the transaction properties
transaction := hedera.NewAccountCreateTransaction(). //Any transaction can be applied here
// Sets the EVM Address from Public Key (recommended for EVM compatibility)
SetECDSAKeyWithAlias(ecdsaPublicKey).
// Use SetKeyWithoutAlias(ecdsaPublicKey). if you plan to rotate keys soon after creation
SetInitialBalance(hedera.NewHbar(1)).
SetMaxTransactionFee(hedera.NewHbar(2)). //Set the max transaction fee to 2 hbar
SetTransactionMemo("Transaction memo") //Set the transaction memo
//v2.0.0
// Create the transaction and set the transaction properties
let transaction = AccountCreateTransaction::new() // Any transaction can be applied here
// Sets the EVM Address from Public Key (recommended for EVM compatibility); takes the ECDSA PrivateKey
.set_ecdsa_key_with_alias(ecdsa_private_key)
// Use .set_key_without_alias(key) if you plan to rotate keys soon after creation
.initial_balance(Hbar::new(1))
.max_transaction_fee(Hbar::new(2)) // Set the max transaction fee to 2 hbar
.transaction_memo("Transaction memo"); // Set the transaction memo
