Bitlight Wallet v1.3.6 Release Notes

- Fixed Payjoin Balance Increase Issue. Fixed an issue where Payjoin could not increase the wallet balance when a locked UTXO contained exactly 330 sats, the dust limit.
- Added Unclaimable Status to Receive Records. A receive record is marked as Unclaimable when the UTXO associated with the received funds has already been spent, indicating that the funds can no longer be claimed.

Lightning RGB: Building an LSP for RGB Assets

https://t.co/y7YrZbbODy

Lightning enables RGB assets to move with low fees and near-instant settlement. At the same time, it introduces new concepts and operational requirements for users.

Every Lightning payment takes place within a payment channel. The channel’s participants first commit funds to the channel, and subsequent payments update the allocation of those funds between the two sides. As a result, the amount a user can receive depends on the balance available on the counterparty’s side of the channel and its ability to be transferred toward the recipient.

This requirement—known as inbound liquidity—is unfamiliar to many new users and is precisely what they are least likely to have when they first begin using Lightning. Before receiving funds, they may need to identify a suitable counterparty, establish a channel, and understand how channel balances and liquidity work. Early users of Lightning Bitcoin encountered the same challenge.

The Lightning ecosystem addressed this challenge through the emergence of Lightning Service Providers (LSPs). Professional Lightning nodes package channel liquidity as a service that users can purchase when needed, allowing them to access inbound liquidity without having to manage the underlying complexity themselves.

We are bringing this model to RGB assets—building an LSP that makes receiving and transacting RGB assets on Lightning more accessible, predictable, and practical.

Lightning RGB: Making Channel Closes Observable

https://t.co/6kQcm0Ar9H

Bitlight Labs closed the asset visibility gap during channel closure in RLN with a dedicated closing view: every channel between "close initiated" and "funds back in the wallet" stays visible, with its exact stage, its remaining outputs, and—for colored channels—the RGB asset amounts and their recovery progress.

This matters because RGB assets on Lightning need the same operational confidence as on-chain — especially during the most sensitive lifecycle event.

• Added detailed failure reasons for unsuccessful swaps.
• Added swap history and transaction details.
• Added the ability to cancel local swaps before execution.
• Added automatic asset recovery using StaticOutput sweep after RGB channel closure.
• Added visibility into pending confirmation and recoverable balances after channel closure.
• Improved channel opening failure handling by releasing reserved funding and automatically attempting a rollback.

Bitlight Labs publishes a complete disaster recovery solution for RGB assets on Lightning Network channels. The wire-level specification is formalized as bLIP-0072, complementing bLIP-0070.

https://t.co/lPi4mmaKfg

Standard Lightning channels already have a well-defined recovery path for BTC: recover from backup, sweep your funds on-chain using your seed. Solved.

RGB assets in Lightning channels are a different problem. Allocations are client-side validated and stored locally—not on-chain. When a channel loses state, the RGB allocation cannot be reconstructed from chain data alone. It exists only in the counterparty's local stock.

bLIP-0072 defines how to retrieve it.

Bitlight Wallet v1.3.1 Released

We are pleased to announce the release of Bitlight Wallet v1.3.1, introducing key enhancements to RGB asset interoperability and browser extension performance.

What's New:

• RGB Asset Consignment Import/Export — Bitlight Wallet now supports importing and exporting RGB asset consignments for RGB Lightning Nodes on Regtest, shipped alongside rgb-ldk-control-panel v0.0.4. This milestone enables developers to test end-to-end RGB asset transfers across Lightning channels in a controlled environment.

• Chrome Extension Optimization — The Bitlight WASM library powering the Chrome extension has been optimized and upgraded.

These updates reflect our continued commitment to advancing RGB protocol infrastructure and delivering a seamless developer experience. We encourage developers building on RGB Lightning to test consignment workflows and provide feedback.

RGB Lightning Node v0.0.4 Released: Full UTXO Management Support

— Control Panel: https://t.co/4OrTd1RaLG
— API: https://t.co/v8XpDPuEI5
— CLI: https://t.co/ixeCa7G7Vy

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.

Bitlight Wallet v1.3.0

We've shipped three targeted improvements in this release:

- PayJoin fee optimization: resolved an edge case where transaction construction produced unnecessarily elevated fee rates.
- Rebroadcast logic refinement: transactions now propagate with greater reliability under adverse network conditions.
- Custom API error handling: Esplora exceptions are now surfaced with structured error codes, improving debuggability for integrators.

As always, we build for precision.

Bitlight Labs has completed its Bitcoin Infrastructure Modernization — upgrading from Bitcoin Core 28.x to v31.0 and deploying Cluster Mempool across our stack.

Full technical write-up:
https://t.co/FXzslCZXMH

What changed:

→ Cluster Mempool replaces per-transaction tracking with cluster-based evaluation. Transactions are now grouped and ordered by chunk feerate, enabling more accurate block template construction and stricter RBF semantics.

→ Fee estimation precision improved from 1 sat/vB to 0.1 sat/vB — reducing overpayment in low-fee environments for wallets and protocol-level settlement.

→ mempool-electrs upgraded to v3.3.0 with multi-tier fee estimation (fastest / halfHour / hour / economy / minimum), while preserving full backward compatibility with existing electrs endpoints.

→ Private broadcast support via Tor/I2P for transaction relay, reducing originating IP leakage.

→ Default dbcache increased to 1024 MB on 4GB+ systems, improving sync and validation performance.

For RGB Layer2 infrastructure, this means more predictable CPFP/RBF behavior, cleaner fee selection for on-chain settlement, and a stronger foundation for commitment transactions.

Our approach: stay close to upstream, reduce unnecessary abstraction, build where the protocol is actually moving.
