There has to be an easier way to add relays, and maybe even set an expiration date for them. If a #nostr client had a way to scan a QR code to connect to a relay, all of the instructions could be included in that, and the client could authenticate on the back end using the user’s npub so they don't have to enter it manually. Add the ability to pay an entry fee by directly pushing an invoice request to the client that opens in their default wallet.
