# assembleTransaction

> Assemble independently collected owner signatures into a signed transaction. Signatures are deduplicated and ordered according to the configured owner set. Account thresholds are read from the local configuration; an explicit transaction signer set determines active MFA IDs and contributing owners. Callers must keep these synchronized with onchain owner and threshold changes.

Method on an account instance returned by [`createAccount`](/sdk-reference/rhinestone-sdk/create-account).

## Usage

```ts theme={null}
const result = await account.assembleTransaction(preparedTransaction, signatures)
```

## Parameters

<ParamField path="preparedTransaction" type="PreparedTransactionData" required>
  The prepared transaction every owner signed
</ParamField>

<ParamField path="signatures" type="OwnerSignature[]" required>
  Owner signatures returned by `signTransaction` with an `owner` option
</ParamField>

## Returns

<ResponseField name="result" type="SignedTransactionData">
  Signed transaction data ready for submission
</ResponseField>
