# Create an unsigned transaction

> Build, freeze, and serialize an unsigned Hedera transaction so it can be signed offline with multiple keys or sent as bytes through an external signing flow.

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.

Will use the 'Client', if available, to generate a default Transaction ID and select 1/3 nodes to prepare this transaction for.</td></tr><tr><td><code>freezeWithSigner(\<signer>)</code></td><td /><td>Freeze the transaction with a local wallet.

<Warning>
  **Account Alias**

  If an alias is set during account creation, it becomes [immutable](/support/glossary#immutability), 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.
</Warning>
