Alpaca, a regulated brokerage business founded by Hitoshi and Yoshi, has successfully transitioned to self-clearing at DTCC, marking a significant milestone in its journey. This achievement demonstrates Alpaca's commitment to innovation and its mission to provide financial access for everyone on the planet. The company's proprietary clearing and settlement platform was built with modern architecture in mind, utilizing idempotent event-driven architecture, Flatbuffers, and Redpanda for efficient high-throughput and low-latency messaging. With self-clearing, Alpaca has joined the deepest layer of clearing and settlement in the U.S. marketplace, opening up opportunities for seamless asset transfers, securities lending, and more sophisticated solutions such as DVP/RVP for institutional trading. The company's team, composed of experienced industry professionals who share its innovative approach, will continue to build and enhance products to provide better customer experiences. Alpaca's self-clearing journey is expected to pave the way for new business opportunities, including options trading, and expand its segments of customers, such as institutional businesses and hedge funds.
