Lnurl with a minor change and support from other blockchains wallet makes it possible to receive payments from other blockchains outside lightning/bitcoin.

The receiver can choose to receive all payments in lightning and transfer to a lightning native wallet if desired.

Imagine a scenario where a Solana user (using a wallet that supports lnurl) can directly send payments to a lightning address of another user (supports handling Solana and lightning payments which is controlled by the service).

While the setup is custodial, this being possible is mind blowing.

From a merchant standpoint, either a QR code of the lnurl or a lightning address is all that's needed to get paid.
