Quant Network was founded by Gilbert Verdian, a cybersecurity expert with over 20 years of experience across governments, central banks, and enterprises globally. Verdian is the originator of the ISO 20022 payment standard committee that governs global banking messaging. Quant's team includes co-founders Colin Paterson and Paolo Tasca. The project raised $11 million in its ICO in 2018. Key institutional partnerships include the Great British Tokenised Deposit (GBTD) project with Barclays, HSBC, Lloyds, and NatWest (completing mid-2026), Bank of Japan collaboration (since January 2026), European Central Bank collaboration, and a Robinhood listing in early 2026. Enterprise partners include Oracle, SIA, and Murex — major financial infrastructure providers.
Quant's flagship product is Overledger OS — a blockchain interoperability platform that connects over 45 public and private blockchains including Bitcoin, Ethereum, Hyperledger Fabric, and CBDC networks through a simple REST API, without requiring changes to existing infrastructure. Developers pay QNT licence fees (locked for 12 months) to access Overledger, creating structural demand for the fixed-supply token. QNT is ISO 20022 compliant — the global payment messaging standard all major banks are migrating to. The QuantNet and Fusion mainnet expansion programme targets becoming the standardised horizontal interoperability layer for CBDCs, commercial bank money, and tokenised assets.
QNT has a fully circulating fixed supply of approximately 14.88 million tokens — all in circulation. QNT peaked at approximately $428 in September 2021 and currently trades around $70 — approximately 84% below its all-time high. The fixed supply with licence-fee demand mechanics is theoretically deflationary — as more enterprises use Overledger, more QNT is locked for 12-month periods, reducing liquid supply. However, this requires actual adoption to materialise.
Quant competes with Polkadot and Cosmos Hub in blockchain interoperability, but from a fundamentally different angle — Quant targets enterprise and institutional deployment through API integration, while Polkadot and Cosmos focus on validator-based chain connections. Quant's ISO 20022 compliance and central bank relationships are genuine differentiators.
Despite genuine institutional partnerships, QNT has declined 84% from its ATH as institutional adoption has been slower than the market initially priced in. Enterprise technology pilots have long timescales. The GBTD project completion in mid-2026 is a key catalyst, but commercial-scale deployment of Overledger across major banks remains an unproven milestone. The token trades primarily on a handful of exchanges with limited retail DeFi presence.
GBTD completes successfully in mid-2026 and Barclays, HSBC, Lloyds, and NatWest proceed to commercial scale deployment on Overledger, creating sustained QNT licence demand; Bank of Japan or ECB explicitly endorses Overledger for CBDC infrastructure; or Robinhood listing drives meaningful retail attention.
GBTD completes but banks choose different interoperability solutions for commercial scale deployment, central bank CBDC projects continue to use proprietary or open-source interoperability rather than QNT's licenced model, or broader crypto market headwinds extend the 84% ATH decline.
We would become more positive if: GBTD transitions to commercial scale with measurable transaction volumes, ECB or BoJ sign material contracts rather than pilots, or on-chain QNT locked in Overledger licences increases significantly. We would become more cautious if: GBTD concludes without a commercial announcement, or enterprise pilot timelines extend further beyond 2026.
Quant has the most credible enterprise blockchain interoperability credentials of any project reviewed on EnterCrypto. Gilbert Verdian originated the ISO 20022 standard that every major bank is now migrating to, and the GBTD project with the UK's four largest banks is the most consequential enterprise crypto pilot completing in 2026. The 84% ATH decline reflects the market's frustration with institutional adoption timelines. If GBTD moves to commercial scale, QNT's fixed-supply licence fee model creates a compelling scarcity dynamic.
GBTD catalyst: The Great British Tokenised Deposit project involves Barclays, HSBC, Lloyds, and NatWest. These are the UK's four largest banks collectively holding trillions in deposits. Commercial-scale adoption of Overledger would create sustained, structural demand for QNT licence fees — a direct test of the investment thesis.
