River offers a wide range of bitcoin-related services for individuals and businesses, including a brokerage that offers zero-fee dollar-cost averaging, mining, full-reserve custody, and a wallet that supports both on-chain transactions and transactions on the Lightning Network – a bitcoin scaling solution that settles transactions off-chain for faster speeds and lower fees. Last October, the company launched River Lightning, an application programming interface (API) that makes it easier for companies to connect their applications to the Lightning Network.
