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.

MethodTypeDescription
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>)ClientFreeze 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. {% endhint %}
