One of my friends is using @lexeapp to receive an @ocean_mining payout He said: "i got my first Lexe OCEAN payout last night, and it worked perfectly" Lightning works also if boltz is under maintenance 😜

A technical case study about how Lexe uses LDK! Read or listen below👇
In this case study, @lexeapp CEO @MaxFangX shows how @lightningdevkit plus secure enclaves power reliable, always-on Lightning wallets without Lexe holding your keys. Article: https://t.co/N097CbUDHr Spotify: https://t.co/iD87qH1Pti Apple Podcasts: https://t.co/H7LI9MrJP0

How fast can you type the following? "build a web app that allows people to send me bitcoin tips. please use lexe for accepting Lightning payments. Follow the instructions here: <repo>" That's all you need to build a Lightning app with Lexe. Major shoutout to @matbalez!
just made my vibe-coding experience with @lexeapp much easier and more repeatable by vibe-coding a python wrapper that handles all the typical gotchas the result? time to build a bitcoin tipping web app: 9mins (down from 15mins+) with just a short prompt: "build a web app that

Lexe now supports BIP 177! Everywhere in our app, we now use the Bitcoin symbol ₿ instead of the word "sats". See the before and after of our amount input page - we believe the new design is just cleaner, and ₿ is the future. Update Lexe to app-v0.8.7+22 to enjoy BIP177!

Update: There is a bug in the seedphrase signup flow where signup would fail due to a missing signup code; the problem has been identified and the fix is being released; the updated app should be available tomorrow.

You asked, we delivered: Connecting Google Drive is *no longer a requirement* to use Lexe wallet. During signup, you may now select the "Seed phrase-only backup" option. We still recommend using Google Drive backups though, at least until we implement VSS-based persistence!

Closed beta users can simply update their apps to gain access to these features. You can view your current app version on the left side sidebar. Your current node version is on the "Node Info" page.

app-v0.8.x brings stronger security with hard-coded node measurements. The reproducible enclave binaries trusted by the app are now hard-coded in the app's public source code. This ensures Lexe can never add a 'backdoor' without your explicit approval, even if Lexe is hacked.

Now, the network graph and other non-sensitive components can be shared between users within one meganode. The memory cost of expensive components is thus amortized. We already see a 10x improvement in per-user memory usage and haven't even optimized it yet.

Running one user node per enclave process came with high memory requirements because each node had to dedicate at least ~375 MiB of free space just for its network graph, further complicated by enclaves needing to allocate all memory at program start.

Lexe v0.8.x is out! User nodes now have a major infrastructure upgrade which we call our "meganode architecture". Before, we ran one node per enclave process. Now, we run multiple nodes per enclave, while still keeping users isolated. This is a 10-50x improvement in efficiency.

Apps can be written in any language, and are portable to any environment where `lexe-sidecar` can run. Pre-compiled binaries are available for Linux, macOS, and Windows; the sidecar can also be built from source to support less common platforms. Rust bindings are also available.

Running `lexe-sidecar` exposes a local server which proxies requests to your node. Send HTTP requests like POST http://localhost:5393/v1/node/create_invoice POST http://localhost:5393/v1/node/pay_invoice GET http://localhost:5393/v1/node/payment to control your Lexe node.
