Lightning Dev Kit

The latest and greatest LDK roadmap is here ⚡️ Several features are underway such as LDK Node, BOLT 12, Anchor Outputs, Async Payments, VSS, Taproot, and more. Other projects will start soon or need contributors 👀 See the 🧵 or join our Twitter Spaces this Tuesday at 9am PST.

In this case study, @lexeapp CEO @MaxFangX shows how @lightningdevkit plus secure enclaves power reliable, always-on Lightning wallets without Lexe holding your keys.

Building stable channels, a bitcoin-native alternative to tokenized fiat. Featuring just-in-time Lightning onboarding and self-custodial trading. Demo powered by @lightningdevkit.

💻 This past weekend at PlebLab, we kicked off our Building on Rust Workshop Series featuring the awesome @benthecarman! 📚 Workshop #1: Building a Rust Wallet with LDK Node We learned how to: → Connect to peers → Open channels → Send & receive sats → Set up an LSP & more → Build from scratch using Rust + @lightningdevkit—all in under an hour! 🤯 🎥 Full demo & GitHub repo: github.com/benthecarman/p… 💫 More about Ben: benthecarman.com ⚡️ Explore LDK: lightningdevkit.org #Bitcoin #LDK #RustLang #BuildersInBitcoin #PlebLab #LightningNetwork #OpenSource

⚡️This weekend we kick off the Building on Rust Workshop Series at PlebLab! First up: Building a Rust Wallet with LDK Node led by @benthecarman 🔧 Learn how to: → Connect to peers. → Open channels → Send/receive sats → Build from scratch with @lightningdevkit RSVP to secure your spot. #Bitcoin #LDK #RustLang #BuildersInBitcoin

Review club this Friday at 19:00 UTC (2:00pm EST)🚀. We will review PR #3593 and learn how to implement BOLT 12 Proof of Payment. 📅Event: discord.gg/5AcknnMfBw 📷Review Notes ldk.reviews/3593

Created a self-custodial Bitcoin Lightning wallet with Nostr Wallet Connect support for the MIT Bitcoin Hackathon! - Lightning with LDK @lightningdevkit - Olympus LSP integration for jit 0-conf payment channels - Flutter for UI - NWC support for any nostr client (@nwc_dev)

Get started with VSS today. Using it is straightforward, as VSS is already integrated with LDK Node v0.4.x+ github.com/lightningdevki…

VSS uses client-side encryption and robust authorization. When a user loses a device, it can facilitate a seamless recovery. Multi-device access will be enabled in the future.

Introducing Versioned Storage Service (VSS): A solution for live online sync and lightning state backup for non-custodial wallets ⚡️ See @G8XSU’s post to learn more about VSS 👇

📢 Join the LDK PR review club this Friday! We'll be reviewing PR #3651, which implements part of the splicing spec - specifically sending and handling `commitment_signed` messages with pending splices. Dive into the tech details with us: ldk.reviews/3651

A quick refresher video on @lightningdevkit 👇

Albyhub is my favorite new piece of Lightning software It's a desktop app that is also a Lightning node (or backed by a Lightning node), so it is reminiscent of bitcoin-qt I had to create a new category called "Lightning Hub" in my workshop for @btcplusplus because of it (chrisguida.github.io/tiny-lightning…). I realized that this category exists after needing either Albyhub or @lnbits as the middleware between a Lightning node and a point-of-sale app, and noticing that this "hub" software is the most convenient place to connect all of your custom/external stuff I love using it with @acinq_co's phoenixd, or you can use it with the excellent @lightningdevkit which is the default.

5/ Ultimately this means faster payments and higher reliability for LDK users. Read more: lightningdevkit.org/blog/ldk-pathf…

4/ We also used our past probing data to more accurately calculate a probability distribution of where liquidity lies on channels in practice (128 * (1/256 + 9 * (x - 0.5)^8)).

1/ Pathfinding has leveled up! Using lots of real-world probing data, LDK spent last year dialing in the way we use historical data. After extensive analysis, we can confidently say our pathfinder leads the Lightning Network in sophistication. Here's how it works 🧵

3/3 🔐 LDK's flexible APIs enabled their remote signing functionality – running nodes on their infrastructure while keys stay with customers like @coinbase. Thanks @lightspark for sharing these valuable insights! 👏

2/3 ⚡️ Here's how they optimized: Instead of each node querying bitcoind separately, they built a single observer process that updates all nodes + caches results. This dramatically cut system overhead and boosted performance. Read more: lightningdevkit.org/blog/how-we-bu…

1/3 📝 New Case Study: @lightspark shares why they chose LDK over other Lightning implementations for their infrastructure. The key differentiators? LDK's unique multi-node management in a single process + deep customization options for their specific needs...
