Company profile
researched Aug 2026Bitlight Labs is a Bitcoin infrastructure developer working on the RGB protocol, a client-side-validated asset and smart contract layer for Bitcoin, and on its integration with the Lightning Network. The company describes itself as a member of the LNP/BP Association and a major contributor to the RGB protocol, and positions its work around building transaction-centric infrastructure spanning protocol code, developer tooling and end-user applications from BitcoinFi to Lightning apps.
Its principal engineering effort is the RGB Lightning Network Node (RLN), built on the Lightning Development Kit (LDK), which allows RGB assets to be locked into a Lightning channel at open time, transferred instantly within the channel and settled on-chain at channel close. The product supports BTC invoices, BOLT12 offers and RGB invoices with automatic amount decoding and QR generation, and ships a local-first, Docker-based development environment with dual pre-funded nodes and pre-issued RGB assets. Consumer-facing work centres on the Bitlight Wallet, a Chrome extension wallet that the company describes as the first Bitcoin wallet unifying RGB and the Lightning Network, and which supports RGB20 assets.
On top of RLN, Bitlight Labs has developed Bitcoin and stablecoin payment frameworks aimed at cross-border payments and AI agent settlement, and states that it works with multiple stablecoin issuers and payment service providers on multi-issuer interoperability, liquidity and merchant settlement flows.
Business model
The company builds core protocol code, open-source developer SDKs and node infrastructure, plus wallets and merchant/payment tooling for RGB assets on Bitcoin and the Lightning Network. Much of its tooling is published as public repositories, and it is funded by venture investment.
Traction
The Bitlight Wallet was launched in April 2024 as a Bitcoin wallet supporting RGB20 assets. The company maintains a public GitHub organization with 31 repositories covering node tooling, SDKs, contract demos and test environments. A first-season BIT token airdrop program has been run, in which users earn points through invitation links and related activities. In September 2025 the company reported raising $9.6 million at a $170 million valuation from more than twenty investors.
Latest developments
In September 2025 Bitlight Labs announced a $9.6 million Pre-A round led by Amber Group and Fundamental Labs at a $170 million valuation, with proceeds directed at RGB protocol contributions, deeper Lightning integration and production deployment of Lightning-native payments, wallets and RGB-based stablecoin rails. The company continues to publish updates to its RGB-LDK node CLI, API mirror, TypeScript SDK and desktop control panel repositories.

Market position
Bitlight Labs presents itself as a core infrastructure provider for native Bitcoin smart contracts and payments, a major contributor to the RGB protocol and a contributor to the Lightning Network. Third-party coverage describes it as focused on trading infrastructure for RGB20 tokens. Tether has announced plans to issue USD₮ on RGB, which the company cites as validation of RGB and Lightning as rails for Bitcoin-native stablecoin payments.
The company emphasizes its dual role as a contributor to both the RGB protocol and the Lightning Network, its RLN implementation enabling RGB assets to move over Lightning channels, a non-custodial wallet described as the first to unify RGB and Lightning, and a zero-configuration local development environment for RGB and Bitcoin Layer 2 work.
Technology
Bitlight Labs works on the RGB protocol, which keeps contract and state data off-chain via client-side validation, allowing asset issuance and transfer on Bitcoin with sharding support and Layer 2 interoperability. Its RGB Lightning Network Node is based on LDK and exposes a local HTTP JSON API, with a CLI, a TypeScript SDK, a desktop control panel for managing local rgbldkd nodes, a wallet connect SDK, a ready-to-use Bitcoin regtest environment, a Bitcoin node deployment stack including Bitcoin Core, Esplora API and mempool with Testnet4 support, an RGB20 contract demo, and a ChatOps agent for operating regtest nodes, channels and BTC/RGB payments through natural language. Public materials cite sub-second finality for payments over RGB-enabled Lightning channels.
Go-to-market
The company distributes open-source repositories, SDKs, quickstart guides and developer documentation to attract builders, ships the Bitlight Wallet through the Chrome extension store, and pursues direct integrations with stablecoin issuers, payment service providers and enterprises.
Developers building on RGB and Lightning, consumer wallet users, merchants, stablecoin issuers, payment service providers and enterprises seeking Bitcoin-based settlement.
