Hello, where can I find seed key (if not mistaken also called as master public key) for development like "tpub........"? For production, I am able to get "xpub......" by using Electrum Dash.
Is it possible to get seed key from Dash Core? Because Dash Core can only generate hd seed and its look like "ad0c5d97f2ba3f7f46cf54a6fcc9817.......".
Or is there any way to run Electrum Dash using testnet?
I'd suggest using a tool like https://iancoleman.io/bip39/ to get this information. Dash Testnet is one of the options.
