RGB Ecosystem at Freedom Tech Summit, BTC Prague 2026

The Freedom Tech Summit (June 10, 2026) included two sessions from RGB Protocol on Bitcoin ecosystem projects. Both presentations addressed production infrastructure for developers building on RGB.

MPC-Secured RGB Lightning Nodes — Renat Skitsan, Utexo

Renat Skitsan, Co-Founder and CTO of Utexo, presented a custody architecture for Lightning nodes that combines Multi-Party Computation (MPC) wallets with validating signing (VLS).

Lightning nodes are inherently hot wallets: funds must remain online inside channels, often at significant scale. This structure creates a critical attack surface: if a node is compromised, an attacker can either steal private keys or trick the node into signing malicious channel states. The architecture Renat presented addresses this point by distributing signing authority across four independent components, each scoped to a single function. No single party, including the Lightning node itself, can move funds unilaterally. The business keeps its identity anchored to the custodian it already uses, and every signing path has a recovery route that does not depend on the cooperation of any one counterparty.

The KaleidoSwap Protocol and SDK — Walter Maffione, KaleidoSwap

Walter Maffione presented the architecture of the KaleidoSwap Protocol, API, and SDK: developer tooling for trustless atomic swaps across Bitcoin L2s. Given the technical audience, the session focused on the SDK with a live demo: how to connect to an RGB Lightning Node, obtain BTC and RGB asset liquidity from a Lightning Service Provider, and execute trustless atomic swaps across Bitcoin L2s, with real code examples throughout.

The presentation addressed a concrete problem for developers: stablecoins and tokenized assets are arriving on Lightning and beyond, and the KaleidoSwap SDK is the integration layer that makes cross-layer swaps possible in practice. The goal was to show how to embed this functionality into other applications, not just use KaleidoSwap as a standalone product.

Side Event and Bitcoin L2 Interest at BTC Prague 2026

The Association organized Freedom Tech Beers — RGB Meetup, an open gathering for builders and conference attendees to discuss RGB Protocol on Bitcoin, infrastructure development, and the state of the ecosystem.

Interest in Bitcoin L2s at BTC Prague 2026 extended beyond the developer community, with notable attention from institutional and traditional finance participants. A recurring theme in those conversations was interoperability: RGB Protocol on Bitcoin is compatible with Lightning, Ark, Spark, and other Bitcoin L2s through a single asset issuance, without bridges. Federico Tenga’s article RGB as the Universal Asset Standard for Every Bitcoin Layer covers this in detail.

The RGB Protocol Association supports ecosystem projects and their presence at major Bitcoin conferences.
