Why JIT Liquidity + Splice Are Critical for Atomic Swaps @BitlightLabs has released the latest update on staying in sync with Lightning development progress, while also introducing several new features planned for future support. @rgbstashlabs provides an in-depth explanation of two key features from this roadmap, along with further context on their significance for Stash Labs products such as RLSP, and Flash Dex. 🔥 Two Core Capabilities Explained: • JIT liquidity for RGB: just-in-time RGB asset channel opening • Splice for RGB: dynamic capacity adjustment of RGB asset channels Building on our RLSP + Atomic Swap capabilities, is about to launch native asset swap trading. However, the current RGB Lightning Network pipeline has key pain points: When a user completes a $RGB buy order via RLN and RLSP, two channels must be opened sequentially: ✅ User opens a BTC channel to pay BTC to the RLSP ✅ RLSP opens a BTC/RGB composite channel to deliver $RGB to the user Three Major Drawbacks of the Current Model: 1⃣ Dual channel opening requires waiting for Bitcoin mainnet block confirmations — typically 6 confirmations — resulting in extremely high transaction latency. 2⃣ Channel capacity is fixed. Once the balance is insufficient for the next transaction, the old channel must be closed and a new one rebuilt — a costly process with high fees and a fragmented user experience. 3⃣ The current model is completely unable to support high-frequency continuous trading scenarios like FlashDex perpetual contracts, severely limiting the RGB ecosystem's trading experience. 🚀 JIT Liquidity | On-Demand RGB Channel Opening JIT (Just-In-Time) liquidity — the core principle is to create on demand, with no pre-lockup required: ▸ Users don't need to pre-fund or manually create RGB asset channels; ▸ When initiating a $RGB receive/swap request, the RLSP instantly generates a virtual off-chain channel — no immediate on-chain settlement needed; ▸ After the first transaction is completed, it is automatically anchored on-chain and converted into an official RGB Lightning channel. 💡 Core Value: • Zero-barrier entry to RGB asset swaps — no idle capital lockup. • Dramatically reduced transaction wait times, eliminating mainnet block confirmation delays. • Enables users to complete $RGB transactions as seamlessly as Lightning BTC, while maximizing RLSP capital efficiency. 🛠 Splice for RGB | Dynamic Capacity Adjustment for RGB Asset Channels Built on the Lightning Network's native Channel Splicing technology, allowing RGB asset channels to be resized without closing or rebuilding: ▸ Splice-in (expand): Add BTC/RGB assets directly to an existing channel; ▸ Splice-out (shrink): Withdraw idle funds from the channel as needed; ▸ The channel remains uninterrupted throughout — no trading pauses required. Only the funding transaction is updated via signatures, requiring a single on-chain confirmation. 💡 Core Value: • Permanently eliminates the old pattern of "close and reopen a channel when the balance runs out". • Seamlessly supports high-frequency continuous trading, enabling FlashDex perpetual contract scenarios. • Significantly reduces on-chain fees from repeatedly opening/closing channels, improving capital turnover and utilization. 🔗 Synergy of Three — Redefining the Atomic Swap Experience • RLSP + Atomic Swap: Powers the underlying asset swap logic. • JIT: Solves the "0 to 1" problem — no pre-built channels, instant trade initiation. • Splice: Solves the "1 to N" problem — dynamic channel scaling to support high-frequency continuous trading. With JIT + Splice landing together, the current pain points of RGB channels — high latency, cumbersome workflows, and the inability to support high-frequency trading — will be fully resolved. This lays a solid infrastructure foundation — high performance, low barriers, and high liquidity — for upcoming Atomic Swap and ecosystem derivatives trading. 🚀 It is worth noting that these two features will not affect the launch timeline — they serve purely as a leap forward in user experience.

Bitlight Labs Technical Update – February 21, 2026 We are pleased to announce significant updates to our RGB Lightning Network (RLN) infrastructure and the release of a new developer sandbox. 1. RLN Node & CLI Enhancements Repository: We have refactored payment logic to a resource-oriented architecture. Key updates include: - Expanded Payment Controls: Added specific subcommands for pay invoice, offer, refund, and keysend. - BOLT12 Support: Integrated BOLT12 capabilities along with wait and abandon payment states in the API and TypeScript SDK. - Documentation: Updated all examples and docs to reflect the new node topology. 2. New Developer Sandbox Repository: We have released a React + TypeScript web frontend for the Bitlight LN Hub to facilitate testing and development. Features include: - RPC Proxy: A backend implementation (in src/app/api) to securely proxy RPC calls and resolve cross-domain restrictions. - Dockerized Environment: Includes a pre-configured Bitcoin regtest container (bitcoind) with scripts for wallet creation and rln-ldk-node server initialization. Developers are encouraged to review the repositories and update their local environments accordingly. Make Bitcoin Smart

Bitlight Wallet & RGB Faucet - Reclaim Permanently Reopened We are reopening the Reclaim process on a permanent basis. All anomalous asset data has been audited and consolidated, and a Reclaim queue has been established according to the amount of the affected assets. From now on, Reclaim processing will not interfere with Claim activities. Who should use Reclaim: 1) Users with corrupted wallets or Failed transfer receipts, as detailed in our prior notice. 2) Users who experienced asset loss and whose previous cases remain unresolved. Key points: - No fees are required for Reclaim; all associated costs are covered by Bitlight Labs. - Ensure your wallet has available UTXOs to receive assets. Eligibility is determined by the verified anomalies linked to your xpub or sender/recipient addresses. The Reclaim amount will match the original affected amount. If you believe you were affected but are not shown as eligible for Reclaim, submit the relevant details in our Telegram channel. We will investigate your case promptly and reconcile it against our records to confirm eligibility. We appreciate your patience and cooperation. Our support team remains available to assist throughout the process.

$LIGHT Airdrop Claiming — Phase I is now live. In this phase, eligibility includes $RGB holders and users who have created mainnet UTXOs and interacted with the RGB Faucet. The RGB Faucet—Bitlight Labs’ first interactive application on RGB mainnet—supported the protocol’s first million-scale stress test. As the first test asset on RGB, $RGB will continue to receive long-term airdrop incentives as the RGB protocol and the Bitlight ecosystem grow. It will also serve as a core asset across key initiatives, including (but not limited to) a decentralized RGB asset marketplace, RGB–Lightning integration, RGB–zk integration, and a Lightning Network–based stablecoin payments network. If you weren’t eligible in this phase, don’t be discouraged. Our commitment to the RGB protocol and the Bitlight ecosystem is long-term and unwavering. A total of 50.64% of $LIGHT has been allocated to the RGB protocol, the Bitlight ecosystem, and the community, to be released gradually as the ecosystem matures. We build in cycles, not weeks. The RGB protocol and the Bitlight ecosystem are at the very beginning of their journey; realizing a global stablecoin payment network will take the steady, collective effort of Bitlight Labs, our peers across the RGB ecosystem, and dedicated community builders and supporters. We’re here for the long haul—focused, patient, and hopeful. We’ll keep shipping, listening, and improving. Thank you for being early and for believing in what we’re building. Together, we’ll make the vision real. Make Bitcoin Smart.
