Yes.

The same node can run stores on different marketplaces at once. One Amazon store, one TikTok Shop, and one Walmart store on that node is fine.

Merca already enforces this. [How login protection works](https://merca.getchrovia.com/en/docs/login-protection): on one IP, each platform allows only one login. What gets blocked is a second login on the same platform, not a store on a different platform.

If a main account and a platform sub-account should share the node, **Allow** the sub-account in that node's **Account records**. See [How to add a platform sub-account](https://merca.getchrovia.com/en/docs/platform-subaccount).
