I'm currently working on opening an HRMP Channel on Rococo with another parachain. In order to do this, I need to send an XCM to the relay chain. One of the items within this message requires a parameter which is the Sovereign Account Address on the Relay.

I was wondering if anyone could provide a link or guide on how to get a Sovereign Account Address?

Thank you in advance.

The quick way for Kusama and Polkadot is to check subscan for the proper parachain: https://kusama.subscan.io/parachain/2023

In the case of most parachains on Rococo, the Owner is also the Sovereign Account. https://rococo.subscan.io/parachain/2000

You can also directly specify the parachain and it will be automatically converted!

X1: {
 Parachain: <parachain-id>
