What is Quant (QNT)? How Overledger and Fusion connect 74 networks for banks

Quant is a British technology company that connects banks and public authorities to blockchains without obliging them to commit to a single chain. The product behind it is called Overledger, supplemented since June 2026 by the Fusion Rollup, which according to the company brings 74 networks together in a shared execution environment. The associated token carries the ticker QNT.

The name became widely known most recently through a mandate from a US clearing house. This article takes a step back and explains what the technology actually delivers, where its limits lie and what role the token plays in it. For the current price there is a separate Quant price prediction; here the subject is the substance behind it.

What Quant is and what banks use the network for

Quant does not build a blockchain of its own. That is the most important sentence about this project, and it is often skimmed over. The company sells an intermediate layer that connects existing networks to one another.

The need for it arises from a practical problem. A bank working with digital assets today deals with several networks at once: public ones such as Ethereum or Bitcoin, permissioned ones such as Hyperledger Fabric or R3 Corda, plus internal systems. Each of these networks speaks a protocol of its own. Building an application for every single one and maintaining it permanently is expensive and ties up staff.

This is exactly where Quant comes in. The bank's application now talks to one interface only, and that interface translates into the respective networks. Technically, such a thing is called an abstraction layer: an intermediate level that conceals differences and presents a uniform picture to the outside.

Overledger: the layer applications dock onto only once

Overledger is the product with which this translation happens. An application connects once, reaches several ledgers through it and does not have to know the quirks of the individual chains. A ledger here is nothing other than a distributed bookkeeping system, that is the database behind a blockchain.

From the perspective of an IT department, the appeal of this design is easy to name. If a new network joins, ideally nothing changes for your own application, because the connection happens one level down. If a network falls away, the same applies. The dependency does shift, though: away from many individual chains and towards the provider of the intermediate layer.

That shift is no footnote but the central objection to the model. Anyone using Overledger trades technical diversity for dependence on a single company. For a bank that is a classic trade-off between effort and supplier lock-in, and it does not fall automatically in favour of the intermediate layer.

Why banks do not simply take a bridge

For moving between blockchains, bridges have existed for years. Such constructions lock a value on one chain and issue an image of it on the other. In private use that works; in banking it runs into three limits.

The first is security. Bridges have for years been among the most frequently attacked components in the industry, because they concentrate large holdings in a single place. The second is legal in nature: an image of a value is not necessarily the same value in law, and for the deposits of a regulated institution that is a problem. The third is settlement. A bank needs certainty that delivery and payment either succeed together or fail together; specialists call this delivery versus payment.

Quant promises to solve these points differently, namely through a shared execution level instead of pairwise bridges. Whether that holds up in practice can only be judged credibly once real payment volumes run across it. So far they do not.

The Fusion Rollup since June 2, 2026: 74 networks in one environment

On June 2, 2026, Quant switched the Fusion Rollup live on the main network. A rollup is a level above a blockchain that bundles many operations and writes only the result back to the main chain. That lowers costs and raises throughput.

According to the company, Fusion is connected to 74 networks at launch. On the public side these include Ethereum, Bitcoin, Solana, Polygon, Avalanche, Arbitrum, Base, BNB Chain, the XRP Ledger, Stellar and XDC. On the permissioned side stand enterprise chains such as Hyperledger Fabric and R3 Corda. Further networks are to be added on request.

Layer 2.5 and the classic rollup: what sets them apart

An ordinary rollup hangs off exactly one parent chain and writes its results back there. According to the company, Fusion is anchored simultaneously to several connected networks and writes its state roots to several destinations. Quant therefore describes the design as Layer 2.5 rather than Layer 2.

The practical difference shows up in an outage. A classic rollup stands still when its parent chain stands still. A level that hangs off several chains is meant to survive that. The price for it is complexity: several anchorings mean more parts that have to work at the same time, and more assumptions about which state applies in a dispute.

Technically, Fusion is EVM-compatible. EVM stands for the Ethereum Virtual Machine, Ethereum's execution environment; compatibility means that existing contracts and tools largely run without rebuilding. For developers that lowers the barrier to entry considerably.

A further promise concerns assets that today lie scattered across the chains in dozens of variants. Fusion is meant to merge them into one uniform form each. Whether that merging holds up everywhere in legal and accounting terms is an open question and not a technical one.

The US clearing house mandate and the timetable to 2027

On September 24, 2026, The Clearing House, the settlement body of the large US banks, selected Quant as technology partner for a network for tokenised deposits. According to those involved, the initiative is backed by 25 large US institutions. For participating houses the network is due to open in the first half of 2027.

Tokenised deposits are not a stablecoin. They are a bank's book money represented on a blockchain; the claim continues to run against the institution and remains subject to its supervision. That is the reason banks prefer this route to the detour via private payment tokens. What exactly was commissioned and what is still open we set out in the report on the clearing house mandate.

Quant takes a second route into the banks via software. Since March 2026 the company has been working with the provider Murex, whose MX.3 platform runs in trading, risk management and post-trade at many institutions. At the industry gathering Sibos, held from September 28 to October 1, 2026 in Miami, both houses jointly demonstrated the settlement of tokenised assets. The thinking behind it is obvious: whoever lands in systems that are running anyway does not have to talk any bank into changing systems.

What role the QNT token really plays in this

Here the technology parts company with the investment, and at this point precision pays. Using Overledger incurs an annual licence fee that is settled in QNT. The tokens used for it are locked for the term of the licence and are not available on the market during that time. When this model was introduced in December 2021, the company named an amount of 100 pounds a year per licence.

According to reports, a customer can also pay in another currency; Quant then locks a corresponding quantity of its own tokens. For demand for QNT on the open market that makes a considerable difference, and it is exactly at this point that the chain of evidence ends.

What remains open is the question that matters most to investors: whether and to what extent the future revenue of the US clearing house runs through the token is not publicly documented. Neither the timetable nor the statements of those involved give figures on it. Anyone claiming that every settled deposit generates demand for QNT goes beyond what is documented.

Does the banks' revenue really flow through QNT?

Two readings stand opposed on this question, and both deserve a fair presentation.

The one: the licence model couples usage to token demand. The more institutions deploy Overledger, the more QNT sit locked, and the smaller the freely tradable quantity. With a maximum supply of fewer than 15 million tokens, every permanently locked quantity carries weight.

The other: a licence fee is a fixed annual sum and does not grow with the volume settled. Ten banks moving billions pay no more under this model than ten banks moving little. The connection between the success of the technology and demand for the token is therefore weaker than it looks at first glance.

Documented is the model itself and nothing more. Everything beyond that hangs on contracts that are not public. Anyone investing in QNT is therefore investing not only in a technology but also in an assumption about how it is billed.

QNT for investors in Germany: venues, licensing and the holding period

QNT is one of the larger crypto-assets and ranks between 33rd and 42nd by market capitalisation, depending on the data service. On October 5, 2026 the price stood at around $263 or about 235 euros, with market capitalisation between $3.2 billion and $3.8 billion. The range arises because the services assume different circulating supplies.

The same applies to supply. As a maximum quantity, figures between 14.61 and 14.88 million QNT can be found, and as a circulating quantity statements between a good 12 and 14.5 million. Anyone calculating with such numbers should write the source alongside, otherwise the result cannot be retraced later.

One point of context, because it shapes every discussion these days: QNT has risen very sharply within a month, in the order of around 300 percent, and is thereby approaching its peak of $427 from September 2021 again. A move like that raises the risk of a setback, but on its own it proves nothing whatsoever about the technology. An assessment of the valuation can be found in our analysis of the current price.

Where QNT can be traded

QNT is listed on numerous venues, including some with a direct euro pair. For investors in Germany what counts above all is whether the provider is authorised as a crypto-asset service provider under the European MiCA regulation. That can be looked up in the public register of the European securities regulator ESMA; decisive is the company with which you conclude the contract. We keep an overview in the comparison of regulated crypto exchanges.

What the tax office sees

Gains from the sale of QNT held as private assets count as private disposal transactions pursuant to Section 23 of the German Income Tax Act. After a holding period of more than twelve months the gain remains tax-free; before that it is charged at the personal income tax rate. Below 1,000 euros of total gain in the calendar year an exemption threshold applies; if it is exceeded, the full amount is taxable. Exchanging QNT for another cryptocurrency also counts as a disposal.

How progress can be read over the coming months

For a project whose promise reaches far into the future, verifiable intermediate steps are needed. Three of them are scheduled or at least observable.

The first is the launch of the deposit network in the first half of 2027. By then it will become apparent whether the selection of a technology partner turns into live operation or into a postponed date. The second is the number of networks connected to Fusion: if it stays at 74, the launch was a one-off event; if it grows, the model is taking hold. The third is the licences themselves. Every new Overledger licence locks tokens, and that lock is in principle traceable on the chain.

What is not a signal of progress, by contrast: an announcement without a contract, an appearance at an industry trade fair or a price move. The gap between a declaration of intent and a productive system is often a span of years with infrastructure projects.

Quant and Overledger: how to proceed now

1. Separate the technology from the token question. Overledger and Fusion solve a real problem for banks; whether the success of that technology arrives at the token depends on the licence model and is not publicly quantified. Anyone deriving an investment decision from it should know which of the two questions they are answering. Where QNT can be traded at all and what the purchase costs is shown by the comparison of crypto exchanges.
2. Settle custody before the amount grows. QNT is a token on Ethereum and can accordingly be held in any wallet that supports the standard. With larger holdings the key belongs out of the exchange; the devices for that are listed in the hardware wallet comparison.
3. Document the purchase date and purchase price from the outset. The one-year period governs the tax exemption, and later it can only be demonstrated with records. Anyone buying across several accounts keeps the record best with a tax tool.
