# Swisstronik & Ethereum transactions

### Ethereum Transactions

When sending transactions in the Ethereum blockchain, there are several fields you need to fill out such as `from`, `to`, `value`, `nonce`, `data`, etc... so the nodes can process and validate your transactions before adding them to the blockchain.

<pre class="language-javascript"><code class="lang-javascript"><strong>signer.sendTransaction({
</strong>    from: //Address of the sender,
    to: //Address of the recipient,
    data: //Data to include in the transaction
    value: //Amount of Ether to send,
  });

</code></pre>

### Swisstronik Transactions

Sending transactions in the Swisstronik blockchain is similar to Ethereum, with one crucial distinction: **when the data field is not empty, the value of the data field must be encrypted**. This encryption step is vital for maintaining confidentiality. By sending encrypted values to the nodes, we ensure that only the nodes can decrypt the data within the [Intel SGX enclave](/swisstronik-docs/general/intel-sgx.md), ensuring the secure validation of your transaction.&#x20;

{% hint style="info" %}
The data field is empty only when sending value between accounts (e.g., sending 1 SWTR from Alice to Bob). For transactions of this type, there is no need for any encryption.
{% endhint %}

```javascript
signer.sendTransaction({
    from: //Address of the sender,
    to: //Address of the recipient,
    data: //THIS VALUE MUST BE ENCRYPTED USING SWISSTRONIKJS
    value: //Amount of Swtr to send,
  });
```
