Quant(QNT)

Quant Network was founded in 2018 by Gilbert Verdian and is UK-based. Quant's own biography of Verdian describes more than 20 years of cybersecurity experience, government roles including Downing Street and HM Treasury, and private-sector roles including Mastercard and HSBC. Quant is not a blockchain. It is an interoperability layer. Its core product, Overledger, is described by Quant as a blockchain-agnostic API gateway that lets applications and banks reach different blockchains and legacy systems through one interface. Quant's February 2026 explanation describes standardized APIs for connected ledgers, legacy-system connectors, and separate transaction preparation, signing, and execution stages. These are the company's descriptions, not an independent implementation audit.

QNT is an ERC-20 token on Ethereum. Its supply is widely cited as fixed at 14,612,493 tokens after a September 2018 burn (for example in Genfinity's September 29, 2026 explainer), but the token contract's totalSupply() function returns 45,467,000 when read from Ethereum on September 29, 2026, so different tools show different figures. Check circulating supply on an explorer before relying on any number. Quant's service terms allow customers to choose QNT for payment and say QNT is the only digital asset accepted for access unless otherwise agreed; card payment is also supported. The terms say services may include QNT staking, but we did not confirm an active retail staking program or yield. Bank adoption alone does not establish proportional QNT demand.

Quant's ISO 20022 connection is a vendor claim rather than a certification. Quant describes QuantNet, its settlement network, as ISO 20022-native, and secondary coverage describes Overledger's PayScript engine as aligning messaging with ISO 20022. ISO 20022 is a financial messaging standard, and ISO does not certify blockchains against it, so read these as design claims. Quant also pitches itself as bridging any chain to systems that speak ISO 20022, which is a different approach from carrying ISO 20022 data on a chain of its own.

The partnership list is short but heavy, and part of it has delivered. On September 24, 2026 UK Finance announced that Barclays, HSBC UK, Lloyds Banking Group, Monzo, Nationwide, NatWest, and Santander had completed the first live customer transactions using tokenised sterling deposits in the GB Tokenised Deposits (GBTD) project: two remortgage completions with funds released automatically at completion, and a consumer marketplace purchase from a private seller. UK Finance states that the transactions ran on the GBTD platform developed by Quant as shared UK industry infrastructure. Separately, on September 24, 2026 The Clearing House announced that it selected Quant to power its On-Chain Money Initiative, a network for clearing and settling tokenized deposits for financial institutions of all sizes, with connectivity to its RTP and CHIPS networks; the network is expected to become available in the first half of 2027. The Clearing House is owned by 25 of the largest US financial institutions and its networks clear and settle more than $2 trillion each day, but the initiative has not yet reached live transactions. The Bank of England lists Quant among the 18 organizations in its Synchronisation Lab, which runs from spring 2026 for around six months; Quant is testing liquidity rebalancing across multiple bank accounts using its Quant Flow corporate orchestration product. On January 14, 2026 Quant and Dentsu Soken announced a partnership to help Japanese financial institutions adopt tokenised deposits, and Quant's announcement says its infrastructure is already deployed in regulated pilots including the Bank of England/BIS Project Rosalind, the European Central Bank, the UK Regulated Liability Network, and GBTD.

Quant announced its Fusion Rollup mainnet launch on June 2, 2026, with connections to 74 blockchain networks at launch. This is a company-reported launch scope, not a measurement of current transaction activity.

The GBTD proof point has delivered live UK transactions, and The Clearing House selection is a second, larger commitment rather than a repeat bet on the same project. Watch whether the US initiative reaches live transactions after its expected first-half 2027 availability, the results of the Bank of England Synchronisation Lab, and whether Fusion drives new enterprise onboarding. Because Quant sells software to institutions, bank adoption and QNT demand are not the same thing.
