# IBC Relayer

{% hint style="info" %}
login to user : salinem
{% endhint %}

**Generate Keys For Gravity IBC | save as file \_ibc-gravity.json**\_

```bash
gravityd keys add ibc-gravity --keyring-backend file --output json     
```

**Generate Keys For Osmosis IBC | save as file \_ibc-osmosis.json**\_

{% hint style="info" %}
If you have not Node Osmosis, Download first binary
{% endhint %}

```bash
