@paullinator Hi, Please see attached video for RNS multichain resolution.
If the user is on RBTC wallet, the multichain resolves the Rootstock address but if the user is on any other wallet, depending on the network, the multichain support resolves address for that network if the user have already set it on our domain management platform. In given video, the user has not setup Bitcoin address, so no address is resolved. Please let me know if anything is not clear.
Have a nice day
Thank you
