Trustless Swaps Across Bitcoin Layers | Walter Maffione SLP772

Walter Maffione, CEO and co-founder of KaleidoSwap, join me to explain how the project grew from an RGB Lightning DEX into a broader swap engine and LSP stack — Lightning as rails between Liquid, Arkade, Taproot Assets, Spark, and RGB — plus KaleidoSDK, desktop app, and browser Extension.

We dig into web app and SDK integrations for merchants and unified-balance wallets, how HTLC atomicity works across layers, BOLT 12 multi-asset offers and Nostr discovery for competing providers, Bitcoin-only scope with Flashnet and Utexo bridges for external stables, and a product lineup of desktop app, browser extension, and dual SDKs.

Walter also covers agentic payments via MCP plugins, self-sovereign local models with Tether’s QVAC, fee ranges around 0.5–1%, and a one-to-three-month mainnet launch path for the extension, swap provider, and web app.
