RGB Lightning Node v0.0.4 Released: Full UTXO Management Support — Control Panel: — API: — CLI: We are pleased to announce the release of RGB Lightning Node v0.0.4, introducing comprehensive UTXO management capabilities that provide users with granular control over their Bitcoin UTXOs for RGB protocol operations. This release focuses on UTXO lifecycle management — a critical infrastructure layer for efficient RGB asset issuance, transfer, and on-chain resource optimization. Key Features: • UTXO Overview — Monitor all UTXOs with real-time status tracking, linked RGB asset visibility, and available operation context. • Create UTXOs — Generate dedicated UTXOs purpose-built for RGB asset issuance, transfer, and management workflows. • Unlock UTXOs — Release reserved UTXOs and consolidate funds back into available wallet balance for flexible resource allocation. • Increase UTXO Capacity — Expand the funding capacity of existing UTXOs to support higher-throughput RGB asset transactions. Efficient UTXO management is foundational to scalable RGB protocol operations on the Lightning Network. This release enables developers and node operators to optimize their on-chain footprint while maintaining full control over asset-linked transaction outputs. Make Bitcoin Smart.

RGB super-compatibility is not a promise but an engineering discipline enforced with zero tolerance for regression. RGB on Lightning: Walking with Upstream While the previous release proved that RGB could connect to Lightning through full LDK state machine compliance, 1,019 tests, and CLN/LND interoperability, the latest release now answers the harder question of whether RGB can evolve at Lightning's pace without friction — and it does. We synced our upstream dependencies with the Lightning mainline, absorbing 16 medium-or-higher security fixes, including critical vulnerabilities that were never backported. We’ve formalised this approach as bLIP-0070, encoding super-compatibility at the protocol layer via feature bits 826 (mandatory) and 827 (optional), along with TLV type 827167. Compatibility only earns the right to the real work of making Lightning’s most advanced primitives asset-native: Splice support, already live in BTC channels, will extend to RGB channels for adjusting capacity without closing, while Async Payments and offline receipt of value will carry over to RGB assets, and JIT liquidity will follow—all without bridges, custodial wrappers, or separate networks, leaving simply the Lightning Network with RGB as its invisible programmable layer. Compatibility is not pitched as a feature; it is shipped as infrastructure, making Bitcoin smart.
