🛠 September Dev Recap

Extension v0.3.0 shipped as our third closed beta, window.rgb became an open standard, and the swap engine is ready to move real funds.

🧩 Extension hits v0.3.0 window.rgb lets the wallet interact with RGB dApps. Add bring-your-own node over Nostr Wallet Connect or straight to LND, Arkade-to-Lightning on mainnet through Arkade Intents, amounts in fiat or sats, and a rebuilt Receive screen.

🌐 window.rgb becomes an open spec Shipped v0.1.0 and v0.2.0 this month: the spec itself, provider discovery across every RGB wallet installed, a mock wallet and conformance suite, and a live playground.

⚡ Swap engine preps for real funds One Lightning invoice now pays out to Bitcoin, Liquid, or Arkade. The engine adds bidirectional BOLT12 swaps, Lightning-to-onchain settlement confirmed with cooperative claims, Arkade-from-Lightning route, and built-in safety rails.

📦 Swap SDK goes multi-platform React Native bindings now ship alongside Rust, TypeScript, and Python, Arkade Intents are built in from every language binding, and validation hardening pulled from boltz-rust checks payment hash and timelocks before funding anything.

⚙️ Also this month → Rate, our mobile prototype, shipped v0.2.3 and is back on TestFlight after an iOS release-build fix. → New on the blog: Bitcoin Payments for AI Agents.

KaleidoSwap Extension v0.3.0 is out 🌈

⚡ Bring your own Lightning node (NWC / LND) 🔁 Arkade → Lightning swaps 🧩 window.rgb: RGB assets for dApps 💶 Amounts in your own currency 📥 Rebuilt Receive flow

Closed beta, apply 👇 kaleidoswap.com/products/extension/beta

🛠 August Dev Recap

Our swap engine learned to move funds without a third-party swap provider in the middle.

Here's what shipped 👇

🔄 Arkade joins the swap engine We built our own solver for Arkade Intents, so we quote, fund, and settle one side of the route ourselves. Live on Mutinynet in both directions: LN→Arkade and Arkade→LN.

🛡 Solver hardening Swap state now survives interrupted claims and refunds cleanly. A security pass closed the month, making sure a swap can't be tricked by manipulated timeouts or a stale price quote.

⚡ RGB Lightning Node v0.9.0 A node no longer needs bitcoind, it can follow the chain through an Esplora-style indexer instead. It also talks to stock LDK nodes now, a real step toward RGB assets moving across the wider Lightning Network.

🧩 Extension moved to v0.3.0 window.rgb, a browser provider RGB dApps can detect and use to issue or move assets. Plus a vanilla Lightning connection over LND or Nostr Wallet Connect, and a reworked Receive screen by method or by account.

⚙️ Also this month → Hardened wallet encryption in the node, scrypt key derivation and XChaCha20-Poly1305. → KaleidoSDK tracked v0.9.0 the same day, adding a setting to pick the chain-following mode. → Diagnostics export in the Extension, so testers can hand over a self-contained report.

Multiple tracks moved in parallel, here's what shipped 👇

🧠 KaleidoMind comes to Desktop Desktop App v0.5.0 ships KaleidoMind, our local-AI layer. It handles everyday tasks, quotes, payments, buying a Lightning channel, one confirmed action at a time.

🧩 Extension second closed beta Node-less RGB as default on mainnet, full Liquid account for L-BTC and other Liquid assets, and encrypted backup to your own cloud storage or a local file.

🔬 RGB on Liquid, early research We prototyped RGB-style programmable assets on Liquid using Simplicity: mint-and-burn rules, time-locked staking, and a full round-trip atomic swap demo.

⚙️ Also this month → RGB Lightning Node reached v0.8.0 upstream, rolling out carefully across our infrastructure. → Explored PIVSS, a backup marketplace paid in bitcoin over Lightning.

🔬 RGB Meets Simplicity

We built a proof of concept for RGB assets running natively on Liquid. The fix upstream is 207 lines, every existing test still passes.

We also demonstrated a Simplicity covenant enforcing an RGB anchor at the consensus level, chain-verified.
