Some of you noticed that I tested a new custom BOLT12 powered "Lightning address" yesterday and had asked for a guide. Here it is!
How to setup a BOLT12 "Lightning address"
I used phoenixd, but you can also use Phoenix Wallet for this too.
1) Download and extract the phoenixd wallet server daemon. You can download it from their GitHub page here: https://github.com/ACINQ/phoenixd
2) You don't need to configure it. You just need to launch the daemon. It will automatically do everything else for you, generating seed words, connecting to the ACINQ LSP, providing you with 2M sats of inbound liquidity to get started, and creating your Lightning offer. You can run this on your existing Bitcoin and Lightning node, desktop computer, etc. Launch it with the command: ./phoenixd
2a) You need to decide on how to make this process always run in the background. You can be lazy and setup a screen, you also be lazy and pipe the output to /dev/null, or you can setup a systemd service.
2b) I setup a systemd service. It's easy and the best way to handle the management of the node, IMO.
3) You will need a domain that you can edit the DNS settings. You will need to enable DNSSEC. This usually requires working with the domain registrar and where your domain records are being hosted, coordinating together and copying and pasting a few fields. It's not hard.
4) Next, you need to add a new DNS record entry. Choose the TXT record type. Configure the TXT record with the following information:
NAME = yourname.user._bitcoin-payment
CONTENT = bitcoin:?lno=your_lno_offer
For example:
derek.user._bitcoin-payment
bitcoin:?lno=lno1zrxq8pjw7qjlm68mtp7e3yvxee4y5xrgjhhyf2fxhlphpckrvevh50u0qv269gw5jl4r3tzduka09pps9rufy7dw8rjl957m6g3t5d5e8gyhcqsrxaemp0q929hz2869l23tgrftggk7wry08aptcu2ccey93xhesefqqvev8d3kh0yk2m3w7xc5fn3h9pkvmj20u53rhakpzuge5e7ccy52gcq7hpf5y866vlkpculf38mn4lyrqkyvqtmrz3hy0desrnzrpvjgm6d57t5y24h97ls2xme3nwk8rrz4dqp52qqsy25a00kv770lqyd9qdj3nu7665
This would give me derek@mydomain.com as a BOLT12 Lightning address.
That's it. Good luck!
