Create an unsigned transaction

These methods allow you to build a transaction that requires further processing before it is submitted to a Hedera network. After you freeze the transaction you can use .sign(privateKey) to sign the transaction with multiple keys or convert the transaction to bytes for further processing.

Method	Type	Description
freeze()		Freeze this transaction from further modification to prepare for signing or serialization. You will need to set the node account ID (setNodeAccountId()) and transaction ID (setTransactionId()).
freezeWith(<client>)	Client	Freeze this transaction from further modification to prepare for signing or serialization. Will use the 'Client', if available, to generate a default Transaction ID and select 1/3 nodes to prepare this transaction for.
freezeWithSigner(<signer>)		Freeze the transaction with a local wallet. Local wallet available in Hedera JavaScript SDK only. >=v2.11.0

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.

Java

//Create an unsigned transaction 
AccountCreateTransaction transaction = new AccountCreateTransaction()
    .setKey(ecdsaPublicKey)
    //Do NOT set an alias if you need to update/rotate keys in the future
    .setAlias(ecdsaPublicKey.toEvmAddress())
    .setInitialBalance(new Hbar(1));

//Freeze the transaction for signing
//The transaction cannot be modified after this point
AccountCreateTransaction freezeTransaction = transaction.freezeWith(client);

System.out.println(freezeTransaction);

//v2.0.0

JavaScript

//Create an unsigned transaction 
const transaction = new AccountCreateTransaction()
    .setKey(ecdsaPublicKey)
    //Do NOT set an alias if you need to update/rotate keys in the future
    .setAlias(ecdsaPublicKey.toEvmAddress())
    .setInitialBalance(new Hbar(1));

//Freeze the transaction for signing
//The transaction cannot be modified after this point
const freezeTransaction = transaction.freezeWith(client);

console.log(freezeTransaction);

//v2.0.5

Go

//Create an unsigned transaction 
transaction := hedera.NewAccountCreateTransaction().
    SetKey(ecdsaPublicKey).
    //Do NOT set an alias if you need to update/rotate keys in the future
    SetAlias(ecdsaPublicKey.ToEvmAddress())
    SetInitialBalance(hedera.NewHbar(1)).
    
//Freeze the transaction for signing
//The transaction cannot be modified after this point
freezeTransaction, err := transaction.FreezeWith(client)
if err != nil {
	panic(err)
}

println(freezeTransaction.String())

//v2.0.0
