Nocturne, a New York City-based company that offers on-chain private accounts, has raised $6 million in seed funding. The round was co-led by Bain Capital Crypto and Polychain Capital, with participation from Ethereum co-founder Vitalik Buterin and other members of the Ethereum community, as well as Bankless Ventures, HackVC, and Robot Ventures. The funding will be used to accelerate the production and deployment of Nocturne's protocol across various ecosystems, as well as to fund legal work to navigate the changing regulatory environment. Nocturne plans to launch on mainnet within the next month, providing a compliant non-custodial privacy option to retail users and allowing for integrations with wallets, payment companies, and other strategic partners.
