This simple plugin adds the ability to pay to a lightning address as described on https://lightningaddress.com/ Some services, such as Bitrefill already offer the posibility to create your own lightning address to top up your account.

Only one command is added and the only obligatory parameters are the address and the msats to send

lightning-cli lnaddresspay address msatoshis [label] [riskfactor] [maxfeepercent] [retry_for] [maxdelay] [exemptfee]

E.g.

lightning-cli lnaddresspay address123@lightning.com 1000000
