Lightning Stock Exchange (Lise) has partnered with Memo Bank to deploy a tokenised equity exchange for small and medium-sized enterprise (SMEs) and mid-caps.
Memo Bank will provide the underlying payment infrastructure, including its banking API and segregated account framework, enabling real-time, atomic delivery-versus-payment (DvP).
Lise’s infrastructure brings together, on a single platform, the functions of a Multilateral Trading Facility (MTF) and a Central Securities Depository (CSD), underpinned by distributed ledger technology (DLT).
This architecture allows Lise to operate 24/7 and to deliver instant settlement
Lise says that this partnership brings together advanced technology and regulated banking capabilities, enabling it to materially shorten traditional settlement cycles and virtually remove counterparty risk.
According to Memo Bank, it demonstrates the strength of its flow-banking model and the robustness of its API, which integrates with the next-generation financial infrastructures.
Mark Kepeneghian, CEO of Lise, says: “To build a next-generation stock exchange designed for SMEs, we needed a banking partner aligned with our technological DNA and our standards of execution.
“Memo Bank’s discipline, combined with the performance of its API, enables us to manage commercial bank money in real time. It is a critical foundation for achieving instant DvP — the cornerstone of our model.”
Jean-Daniel Guyot, chairman of the management board, Memo Bank, adds: “We are proud to support Lise in this ambitious and cutting-edge market infrastructure. Our premium API technology and segregated account capabilities are powering a sophisticated DLT architecture designed to broaden SMEs’ access to capital markets.”
