The new Primal 3.0 that's launching next week uses the same technology as the wallet in Agora. You can take your Agora backup and restore it to Primal or you can take your existing Primal wallet and import it to Agora. Either method here would allow you to use the same wallet in both apps.
I'm this example, I created a brand new wallet in Agora, restored it to Primal, and then sent 21 sats from my Strike wallet to derekross@primal.net and it shows up in both Primal and Agora.
Wow! That's amazing. Even though every transaction -- IP address, user-agent, everything else, is monitored by LightSpark, controlled by a family so close to the state of Israel? That seems incredible.
when you migrate your primal to their new setup, which i did a few days ago and it's just a couple taps of a button an really easy, then you'll get 12 words that you can use as a backup. you could take these and import them into Agora if you'd like, and use the same wallet in both apps. you could also setup NWC if you prefer to use that too. you're going to eventually have to migrate Primal's wallet from their Strike backend to the new Breez Spark SDK powered one.
