About this app

⚠ IMPORTANT: be sure to save a mnemonic phrase once a new wallet is created. Having a mnemonic phrase is the ONLY way to recover your balance in case of serious bugs or phone loss ⚠

This app contains a standalone Bitcoin and Lightning node in a single package. It allows to send and receive regular Bitcoin transactions as well as Lightning payments.

Ratings and reviews

BLW is a fantastic wallet! However, it really does need some way to set the transaction fee. There are also times that I need to receive lightning funds, but my channel is full. I've found that using a third party service like Lightning Conductor to do a ln->btc transaction useful in these scenarios.. but it would be nice to do that all in BLW. 2022 UPDATE: This wallet was great, but I think that the developers moved on to create the SBW app, so I have switched to that one.

Best on boarding experience to lightning I've seen so far. The wallet runs a full lightning node on device so you need a minimal understanding of lightning to set up channels, but the wallet is really helpful in helping you through the process. The UX is very well thought out, the UI is polished and I didnt encounter any glitches.

This wallet is simply the best Bitcoin Lightning Wallet. It has everything one may need and they all work flawlessly. You can open both custodial and non-custodial Lightning channels. Custodial channel can be used more easily and to start receiving immediately, and non-custodial channels can be used for more security and to have more control. I wish you devs success and looking forward for more features. I wondered why you deprecated such a gem. Thank you for undeprecating it.
