I'm on Solana. Can I use DegenPhone?

DegenPhone has a Solana edition on its own site, sol.degenphone.xyz. It works the same way: the number is a real Estonian +372 number, held as an NFT in your Solana wallet. Open the site in the browser inside the Phantom wallet app.

Your SMS show in My Numbers on that site. You can't move a Solana number to TON yet.
