Quant(QNT)

Quant Network was founded in 2018 by Gilbert Verdian, a cybersecurity expert who previously led blockchain strategy at the UK Treasury, Mastercard, and HSBC. The company is based in London. Quant is not a blockchain. It is an interoperability layer. The core product, Overledger, connects different blockchains, legacy banking systems, and enterprise databases so they can exchange data and value without any of them needing to change their underlying code.

Overledger uses a four-layer architecture: Transaction, Messaging, Filtering, and Application. It sits on top of existing networks as a lightweight software layer, similar to how TCP/IP sits on top of physical network infrastructure. The platform provides REST APIs that let developers build multi-chain applications (mDApps) that can simultaneously use smart contracts on Ethereum, authenticate on Hyperledger, and settle transactions on another chain. QNT is an ERC-20 token with a fixed supply of approximately 14.6 million. The token is required to access the Overledger network: developers and enterprises pay QNT for licenses, API calls, and gateway operations. You can pay in fiat, but the Quant Treasury converts it to QNT behind the scenes. That fixed supply plus mandatory usage creates a direct link between platform adoption and token demand.

Quant's ISO 20022 connection is among the deepest of any project on this list. QuantNet, the programmable settlement network, was built from the ground up to meet ISO 20022 standards with embedded audit compliance, regulatory reporting, and risk management controls. Overledger acts as a translation layer between ISO 20022-formatted bank messages and blockchain transactions. Where Ripple and Stellar carry ISO 20022 data natively on their own chains, Quant connects any chain to ISO 20022-speaking systems. The approach is different but arguably more useful for institutions that need to bridge multiple networks.

The partnership list is short but heavy. UK Finance selected Quant to provide the technology for the GB Tokenised Deposits (GBTD) project, a consortium including Barclays, HSBC, Lloyds Banking Group, NatWest, Nationwide, and Santander, running through mid-2026. The Bank of Japan chose Quant (with Dentsu Soken) for blockchain settlement experiments under BIS Project Agora. The Bank of England included Quant in its Synchronisation Lab, testing atomic settlement for multi-bank treasury operations starting February 2026. Quant contributed to BIS/Bank of England Project Rosalind for retail CBDC API design. Oracle certified Overledger as an interoperability solution for its blockchain platform.

In 2025, Quant launched Quant Flow for institutional payment automation and compliance workflows. QuantNet debuted at Sibos 2025 and was announced as the architecture behind the GBTD infrastructure. The Overledger Fusion Mainnet is planned for 2026, along with a Trusted Node Program introducing QNT staking for the first time.

Watch the GBTD project outcome. If six major UK banks run live tokenised deposit transactions on Quant infrastructure through mid-2026, it validates the entire thesis. Also watch the Bank of Japan/BIS Project Agora results and whether the Overledger Fusion Mainnet launch drives new enterprise onboarding. QNT's fixed 14.6 million token supply means even modest institutional demand could have outsized price impact.
