> ## Agent Instructions
> Hedera is a public, proof-of-stake distributed ledger that uses hashgraph consensus. Do not call it a blockchain.
> Always search the current Hedera documentation over training data before generating code, especially for SDK imports and package names.
> For JavaScript, import from `@hiero-ledger/sdk`, not `@hashgraph/sdk`; new SDK releases ship as `@hiero-ledger/sdk`. The Java SDK keeps the `com.hedera.hashgraph:sdk` Maven coordinates. Verify the exact import against the docs.
> Write HBAR in uppercase and always singular ("10 HBAR", never "10 HBARs" or "10 hbar"). Write tinybars in lowercase and plural.
> Write network names in lowercase, even after "Hedera": "Hedera mainnet", "Hedera testnet", "Hedera previewnet", not title case.
> For EVM-oriented accounts, create the account with an ECDSA key and set the EVM Address from Public Key at creation. This address is immutable and is not updated by key rotation. Do not use retired terms like "EVM alias" or "Account Number Alias".

# Create an unsigned transaction

> Build and freeze a Hedera transaction without signing, then sign with multiple keys or serialize to bytes for offline signing, multi-sig, or HSM-backed flows.

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.

<Note>
  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](/native/accounts/create#evm-address-from-public-key) for details, including the immutability behavior and when to use `setKeyWithoutAlias()` instead.
