# Whitelist URLs

### Super Validators

Tradecraft needs to communicate with Super Validator nodes to get disclosed contracts that are not available on the local participant node.

Update your firewall/egress rules to whitelist all the Super Validators listed here:

<https://sync.global/sv-network/>

This step is typically already completed when setting up your node as described here:

<https://docs.sync.global/validator_operator/validator_networking.html#egress>

### Token URLs

{% embed url="<https://api.tradecraft.fi/v1/tokens.json>" %}

Also whitelist the URLs for any of the tokens you wish to trade in the above file.

{% hint style="info" %}
We intend to remove this step from the install process in the future and make new tokens immediately available to trade without manual whitelisting.
{% endhint %}
