Quant partnerships: who actually works with Quant Network

How to read "partnership" claims in crypto

"Partnership" is the most inflated word in the industry. It covers everything from a signed multi-year contract with a bank consortium to a logo on a cloud provider's partner directory, and the price reaction is often the same for both. For Quant the problem is sharper than usual, because the company sells to institutions that rarely tweet, and because quant.network itself blocks automated access, so much of the community's knowledge comes second-hand.

We sort engagements into three tiers. Confirmed means the counterparty, a central bank, a trade body or a vendor, said it in its own release or on its own site. Partly confirmed means Quant's version is plausible and consistent with public records but a specific detail, such as a marketplace listing, cannot be found. Unverified means we found no primary source at all. Everything on this page carries one of those labels, and we would rather downgrade a real relationship than upgrade a rumour. If you want the full company background first, start with what Quant is.

Central banks and standards bodies

BIS Innovation Hub and Bank of England: Project Rosalind

Rosalind, run by the BIS Innovation Hub London Centre with the Bank of England from 2022 to June 2023, prototyped an API layer for a retail CBDC and delivered 33 API functionalities across more than 30 use cases. The BIS does not name vendors; Quant announced on 16 June 2023 that it was part of the vendor team supplying infrastructure, smart contracts and ledger interoperability, and UST said on 27 June 2023 that it was the innovation vendor building the API layer. The BIS calls the project "purely experimental". It is a completed engagement, not a standing partnership, and the CBDC page covers what it did and did not prove.

European Central Bank: innovation-platform pioneer

On 5 May 2025 the ECB announced almost 70 participants for its digital euro innovation platform. A reproduction of the annex lists Quant Network Europe Limited in the "pioneer" workstream, which tests conditional payments against ECB specifications and an API. That is confirmed. What is not true is that the ECB selected Quant to build the digital euro; component providers were procured separately, and the platform is a sandbox shared with dozens of firms.

INATBA and ISO standards

Quant was a founding member of INATBA, the International Association for Trusted Blockchain Applications, in 2019, with Gilbert Verdian on its standards committee. Verdian also initiated the ISO/TC 307 blockchain standards work in 2015 and convenes its interoperability working group, according to his own and several conference bios; ISO's committee page lists no convenor names. ISO/TS 23516, an interoperability framework technical specification, was published in March 2026. Standards work is reputational rather than commercial, but it explains why Quant keeps turning up in official-sector projects.

Banks and payment networks

UK Finance: Regulated Liability Network and GBTD

Two separate programmes. In April 2024 UK Finance selected R3 and Quant as technology providers for the RLN experimentation phase: R3 supplied the Corda-based ledger, Quant the orchestration and API layer through Overledger. Eleven institutions took part, including Barclays, Citi, HSBC, Lloyds, NatWest, Santander, Mastercard and Visa, and the report landed in September 2024. Then in September 2025 UK Finance picked Quant to build the Great British Tokenised Deposit platform for Barclays, HSBC UK, Lloyds, NatWest, Nationwide and Santander, with Monzo joining in January 2026. In late September 2026 the banks completed the first live customer transactions, including two remortgage completions. That is the single strongest piece of evidence on this page.

The Clearing House

On 24 September 2026 The Clearing House, which runs the RTP and CHIPS systems in the United States, announced that it had selected Quant to provide the interoperability, orchestration and transaction-management layer for its On-Chain Money Initiative, an interbank network for tokenised deposits, expected to be available to participating institutions in the first half of 2027. TCH published this on its own site and via PR Newswire. Note what the release does not say: it does not mention QNT, and it does not say banks will hold the token.

SIA, now Nexi

SIA, the Italian payments infrastructure company since merged into Nexi, announced on 5 June 2019 that it would integrate Overledger with SIAchain, its private network connecting around 580 European nodes, and in June 2020 reported a successful interoperability test spanning SIAchain, Corda and a private Ethereum network. It is confirmed by SIA's own release, and it is also old; no live product using it has been disclosed since.

Pay.UK

Quant Network Limited appears on the list of 38 guarantors of Pay.UK, the company that operates Bacs and Faster Payments. Guarantors are the member-equivalent of shareholders in a company limited by guarantee: they hold the board to account. It is a governance seat, not a technology contract, and should not be read as "Quant powers Faster Payments".

The Oracle relationship, properly described

Searches for "quant oracle partnership" usually expect a single big deal. The record is a sequence of smaller, verifiable steps. In 2019 to 2020 Quant was accepted into the Oracle Global Startup Ecosystem, and in June 2020 trade press reported Quant would run Overledger on Oracle Cloud Infrastructure as an Oracle fintech partner. In November 2021 Oracle's own blockchain blog described certifying Overledger for interoperability with Oracle Blockchain Platform on OCI. Then on 13 February 2025 Oracle launched Oracle Blockchain Platform Digital Assets Edition, which, per Oracle's blog, integrates Quant technology.

So: partner status, a technical certification and a product integration, all documented by Oracle. What we could not find is a live Oracle Cloud Marketplace listing for Overledger; treat that specific claim as unverified. One more disambiguation, because it causes confusion: Quantinuum, the quantum-computing company that trades under the ticker QNT on Nasdaq, has its own 2026 Oracle relationship that has nothing to do with Quant Network. The QNT stock versus token page untangles that.

Technology partners

Murex

On 25 March 2026 Murex, whose MX.3 platform is used by banks for trading and risk, announced that it had embedded Overledger and Quant Flow into MX.3 to support tokenised deposits and digital-bond settlement. Murex says ten clients are live on MX.3 for digital assets, but no named bank using Quant through Murex has been disclosed. Confirmed by Murex; commercial scale unknown.

R3

R3 was Quant's co-provider on the UK RLN and published the selection on its own site. Corda is one of the permissioned ledgers Overledger has historically connected, which is the practical reason the two were paired.

Dentsu Soken

The Japanese IT services arm of the Dentsu group signed a go-to-market partnership with Quant on 14 January 2026 to support adoption of tokenised deposits in Japan. Quant also announced a Japanese patent for multi-ledger token technology in February 2026. A CEO post in October 2026 teasing a "programmable yen" is a teaser, not an announcement.

UST

UST, the digital-transformation firm, was the innovation vendor on Rosalind and in 2023 announced a partnership with Quant to accelerate institutional digital-asset adoption. Both facts are on the record via BusinessWire and trade press.

Amazon Web Services

Searches for "quant coin amazon" usually trace back to March 2019, when Quant became an AWS Partner Network technology partner. That is a real but modest status shared by thousands of software vendors. Community posts often upgrade it to an AWS Marketplace product listing for Overledger; we could not find one, so that detail is unverified. Overledger Authorise, Quant's key-management product, does use AWS KMS hardware security modules, which is a technical dependency rather than a partnership.

Hyperledger and LACChain

Quant joined Hyperledger, now LF Decentralized Trust, in 2019; whether it remains a member is unverified. LACChain, the Latin American blockchain alliance led by the Inter-American Development Bank's IDB Lab, signed a memorandum with Quant in early 2021 under which Overledger serves as an interoperability gateway to LACChain's Hyperledger Besu network, with a cross-border payments use case reported by Ledger Insights. The interoperability page explains why permissioned networks like Besu and Corda are where Overledger has spent most of its history.

The Mastercard myth, addressed honestly

"Quant Mastercard partnership" is one of the most searched phrases about the company, and the answer is uncomfortable for fans: no Mastercard press release, and no current Quant release, describes a bilateral partnership. The connection is biographical. Gilbert Verdian was chief information security officer at Vocalink, which Mastercard acquired for about $920 million in 2016 to 2017, and left in 2018 to run Quant full time. David Yates, the former Vocalink chief who later ran Mastercard's new payment platforms, sits on Quant's board. A 2018 Quant tweet refers to "continued collaboration with Mastercard" with no detail.

The closest institutional link is that Mastercard was one of eleven participants in the UK RLN experiment for which Quant was a vendor. That is a UK Finance programme, not a Mastercard deal. People with Mastercard history run Quant; Mastercard the company has not, as far as any public record shows, contracted with it. We will update this if that changes, and the news page is where it would appear first.

What partnerships do and don't mean for token value

Three gaps separate a press release from a higher QNT price, and each is wide. The first is between announcement and revenue: a pilot or a certification can produce nothing, and Quant does not report revenue by customer. The second is between revenue and token demand: Overledger licences can be paid in US dollars as well as QNT, and no counterparty has said it will hold the token. The third is between token demand and price: QNT's supply is fixed at about 14.6 million, but a few thousand tokens of licence demand are small against daily trading volumes of tens of millions of dollars. The tokenomics page quantifies the licence mechanism, and the review weighs it against the risks.

What partnerships do establish is credibility, which matters for a company selling to banks. A vendor that has shipped a live platform for seven UK banks and been selected by the operator of the US dollar's core payment rails is a different proposition from one with a whitepaper. It is also fair to note the market's own behaviour: QNT roughly doubled in the days after the TCH announcement and fell back almost as fast. Announcement spikes are volatility, not validation, and the Fusion rollup's use of QNT for gas and staking, live since June 2026, may over time matter more than any logo.

How to verify a partnership claim yourself

The method we use takes a few minutes per claim and needs no special tools.

Applied consistently, this method yields the map at the top of the page: a dozen confirmed engagements, a couple of partly confirmed ones, and two famous names that do not belong on the list at all. That is still a strong roster for a company of Quant's size; it simply is not the one the memes describe. For the people and dates behind each milestone, see the history page.
