# Encode Transaction

All multisig requests must be encrypted through Keychain to ensure that only the valid initiator and potential signers have access to them. Therefore we provided a utility function to encode as follows:

### Encode Transaction

{% hint style="info" %}
Begin by encapsulating the operation using [hive-tx Transaction()](https://github.com/mahdiyari/hive-tx-js#:~:text=axiosAdapter%20%3D%20fetchAdapter-,Create%20transaction%3A,-const%20tx%20%3D), then integrate it into the 'IEncodeTransaction' object.
{% endhint %}

<pre class="language-typescript"><code class="lang-typescript">const multisig = HiveMultisig.getInstance(window: Window,options?:MultisigOptions); 

const op: Hive.TransferOperation = [
      'transfer',
      {
        from: 'joe',
        to: 'jane',
        amount: 1,
        memo: 'payment',
      },
    ];

const _hiveTx = new hiveTx.Transaction();
const transaction  _hiveTx.create([op], getSeconds(expiration))
const txEncode: IEncodeTransaction = {
          transaction: transaction,
          method: 'posting',
          expirationDate: expiration,
          initiator: 'joe',
        };

<strong>const encodedTx = await multisig.utils.encodeTransaction(txEncode)
</strong></code></pre>

The `multisig.utils.encodeTransaction()` function will automatically assign the encoded message to all potential signers. This process encodes the transaction through Keychain and returns the 'RequestSignatureMessage' object.

### IEncodeTransaction object
