Lightning Labs

Lightning Labs develops software for the Lightning Network, which is a layer-two solution for Bitcoin. While it doesn't offer a full suite of financial services like Cash App, its core focus on enabling faster and cheaper Bitcoin transactions directly aligns with the 'Bitcoin Trading' feature, as it facilitates the movement and management of Bitcoin. The website explicitly mentions 'building faster, cheaper, global layer-two bitcoin' and 'send and receive money more efficiently than ever before' using the Lightning Network, which is fundamentally about transacting with Bitcoin. However, it does not offer other features like P2P transfers in a general sense, prepaid debit cards, direct deposit, or stock trading, as it's a developer of infrastructure rather than a consumer-facing financial app.
