About the Company
- Quant is a global leader in digital transformation and technology solutions.
- Quant is a leading provider of programmable money infrastructure, and our technology changes that: it lets banks issue, move and settle tokenized deposits around the clock, automatically and securely, while staying connected to the systems they already run on.
- It is already deployed in regulated environments with central and commercial banks in the UK and around the world, including work on the digital pound and the digital euro.
- The Clearing House, whose networks clear and settle more than $2 trillion a day, has now selected Quant to power its On-Chain Money Initiative: a new interoperable payments network that will let financial institutions of all sizes clear and settle tokenized deposits, with connectivity to the RTP® and CHIPS® networks.
- Our technology provides the network's interoperability, orchestration and transaction-management layer, enabling payments that settle immediately and transactions that trigger automatically once agreed conditions are met.
- Through our Tokenized Deposits-as-a-Service solution, banks of any size can join without building new infrastructure themselves.
- The network is expected to become available to participating institutions in the first half of 2027, with use cases across corporate treasury, liquidity management, cross-border payments and digital asset settlement.
- We are building the New York team that will run it.
