Deep Dive
1. Wallet SDK Update (17 Dec 2025)
Overview: The JavaScript SDK now enables payjoin transactions, allowing users to combine payments into a single Bitcoin transaction.
This update introduces methods like payjoinBuy() and payjoinSellConfirm(), which let applications coordinate multi-party payments without revealing individual transaction details. The SDK supports Lightning Network invoice integration for atomic swaps.
What this means: This is bullish for LIGHT because it enhances transaction privacy and reduces on-chain fees for Bitcoin users – critical for scaling microtransactions on the Lightning Network. (Source)
2. Integrated L1/L2 Architecture (16 Oct 2025)
Overview: A new whitepaper outlines a unified architecture combining Bitcoin’s base layer with Lightning Network and RGB protocol execution.
The code separates signature operations (handled on Layer 1 via Taproot) from node operations (processed on Layer 2), aiming to reduce costs while maintaining Bitcoin’s security model.
What this means: This is neutral-to-bullish for LIGHT, as it theoretically enables more complex smart contracts on Bitcoin, but success depends on developer adoption of the new framework.
3. RGB Regtest Environment (1 Sep 2025)
Overview: A preconfigured testing setup simplifies RGB contract development with tools like Bitcoin Core and Esplora API.
The environment includes sample RGB20 token contracts and stress-testing utilities, allowing developers to simulate asset issuance and transfers without mainnet risks.
What this means: This is bullish for LIGHT because lower barriers to entry could accelerate ecosystem growth around Bitcoin-based assets. (Source)
Conclusion
Bitlight’s recent code commits prioritize infrastructure for Bitcoin scalability and developer tooling – aligning with its vision for RGB-powered smart contracts. While technical progress is evident, the $0.445 price (-75% from ATH) suggests markets remain skeptical about adoption timelines. How might upcoming protocol audits or partner integrations shift this narrative?
