Bitlight Labs has successfully raised $9.6 million in a Pre-A funding round, with Amber Group and Fundamental Labs leading the investment. The round also saw participation from UOB Venture Management, Signum Capital, ArkStream Capital, and others. The funds will be directed towards integrating the RGB protocol with the Lightning Network, aiming to create a low-fee settlement system for Bitcoin-native stablecoins. This initiative is expected to benefit the wallet and merchant ecosystem, further advancing the development of Bitcoin, the Lightning Network, and the RGB protocol.
