# HMND/eHMND swap guide

{% hint style="info" %}
This is a low-level guide intended for developers to illustrate how things work on the technical side. We plan to ship an easy-to-use UI intended for non-technical users later on in the Testnet 5 lifecycle.

{% hint style="danger" %}
This guide mentions outdated Chain IDs. Make sure to lookup the correct one for your chain from the [Chains](https://app.gitbook.com/s/zrqdNEWk4W56lbUfbpyD/chains "mention") page.
{% endhint %}

You should have:

* `hmAddress...` - your native substrate based address on the Humanode network. The address should be imported into a [polkadot.js extension](https://polkadot.js.org/extension/). If you don't have one, then go through [the guide](https://app.gitbook.com/s/zrqdNEWk4W56lbUfbpyD/tools-and-services/polkadotjs-extension/wallet-setup) to set up one.<br>

* `0xAddress...` - your ETH address that is imported into a ETH supported wallet connected to Humanode Israfel Testnet. In this case, it's **Humanode Testnet 5** with the following rpc url: `https://explorer-rpc-ws.testnet5.stages.humanode.io`.<br>
