Did you connect the Lightning wallet to your node?
Discussion
I wanted to transfer money from BW's Bitcoin wallet to my Alby wallet or WOS wallet's Lightning wallet, but entering the addresses of both wallets prompted "invalid address". Is it not possible to transfer directly to the Lightning Wallet?
To my knowledge, the only way to have a functional Lightning Blue Wallet is to self host, like as you mentioned, BW ended custodial hosting services a while back.
Maybe shoot it over on chain to a Muun Wallet and then transfer to a lightning wallet of your choice?
I see, what you mean is that BW no longer has a Lightning wallet hosting service, nor does it have a default Lightning node. So I can't transfer out of BW, I need to find a wallet that has lightning node hosting, and this wallet also has a Bitcoin wallet on the chain. So I can transfer money from the on-chain Bitcoin wallet to the Lightning wallet?
Yes, or connect BW Lightning to a node you’re running. Those are the two options.
