Quant (QNT) - the full guide

1. TL;DR

Quant is not a blockchain. It is a London-based private company, Quant Network Ltd, that sells Overledger: a gateway and set of APIs that let a bank or enterprise application talk to many blockchains at once, public and private, through one set of credentials. Since June 2026 the product also includes the Fusion Rollup, an EVM execution environment that anchors to several chains at the same time. ^[13][1][2]

QNT is the company's token. It is an ERC-20 token on Ethereum, not a native coin, which matters a lot for how you store it. The supply is fixed: 14,612,493 QNT after the company burned the unsold tokens from its 2018 sale, and at the time of writing about 14.56 million were circulating. ^[9][11][12]

What is QNT for? Licence and platform fees for Overledger can be paid in QNT, nodes connected to the platform can have QNT staked against them, and Quant says the Fusion Rollup will use QNT for gas and execution fees. The company also accepts US dollars for platform fees, and QNT carries no governance rights. ^[12][3][4]

Quant's credibility rests on named public-sector work rather than on-chain volume. The BIS Innovation Hub's Project Rosalind report lists Quant alongside UST as the project's vendor team, Quant was one of two technology partners in UK Finance's Regulated Liability Network experiment in 2024, and in September 2026 The Clearing House in the US selected Quant to build the interoperability layer of its tokenized deposit network, expected to open to banks in the first half of 2027. ^[21][25][32]

The main things to understand before holding QNT: Overledger is closed-source software run by one company; the company files small-company accounts and publishes no treasury reports; Quant itself operates the Fusion sequencer; demand for the token depends on the company's commercial choices; and because QNT lives on Ethereum you need ETH to move it from a self-custody wallet. ^{[39][14][12][42]}

3. What problem does it try to solve

Picture a large bank in 2026. Its payments run on decades-old core systems. Its bond desk is testing a permissioned ledger from one vendor, its custody arm holds tokenized funds on Ethereum, a partner bank uses Hyperledger Fabric, and a regulator wants every one of those systems to talk to each other and to existing payment rails. Each ledger speaks its own language, has its own node software, its own signing rules and its own failure modes. ^[1][3]

Gilbert Verdian, Quant's founder, framed the problem in 2015 while working in government: he "wasn't happy that blockchain was progressing in silos," and compared the moment to the 1990s, when CompuServe, Prodigy and AOL ran proprietary networks that could not talk to each other until open internet standards won. His answer was twofold: an international standard, which became ISO/TC 307, and a commercial product, which became Overledger. ^[17]

Overledger's pitch is a single entry point. A developer gets one set of credentials and one API, and behind that door Quant runs "connectors" that translate requests into the native protocol of each chain: EVM chains, Solana, Cosmos, Sui, Hedera and Aptos on a self-serve basis, and permissioned networks such as Hyperledger Fabric, R3 Corda, Canton and Oracle Blockchain Platform through a managed engagement. The analogy Quant itself leans on is an operating system: applications should not care which hardware they run on. ^[1][3]

The second half of the problem is moving value between chains without a bridge. Bridges are third-party contracts that lock a token on one chain and mint a copy on another, and they have been the site of some of the largest thefts in crypto history. Quant's Fusion Rollup tries a different structure: one execution environment whose state is derived from all connected chains at once, so that a single contract can receive deposits from, and settle to, any of them. Whether that is safer in practice is one of the open questions we return to in chapters 5 and 11. ^[2]

Why should an ordinary reader care? Because the customers Quant targets are the institutions that hold your deposits. If tokenized bank deposits, central bank digital currencies and tokenized securities do become mainstream, somebody has to build the plumbing between them and the systems that already exist. Quant wants to be that plumber, and QNT is the token attached to the plumber's business. ^[32][21]

4. History, founders, organization and governance

The founder and the ISO standard

Gilbert Verdian is a career information-security executive. His speaker biography lists CISO, CIO and CTO roles at Downing Street, HM Treasury, the Cabinet Office, the Ministry of Justice and NSW Health in Australia, and private-sector roles at Mastercard, Vocalink, CSC, EY, PwC, BP and HSBC. In his own slides for a 2021 WIPO webinar he dates his first contact with Bitcoin to 2009 at HM Treasury, where an economic assessment concluded the technology "will not have any material impact to the UK's economy." ^[19][17]

The ISO story is often told loosely, so here is what the primary sources say. Verdian's slides date the concept of a blockchain interoperability and governance standard to 2015 and the drafting of a proposal "with Standards Australia" to 2016. Standards Australia's own account says it submitted a New Field of Technical Activity proposal to ISO in April 2016, that ISO approved it in September 2016, and that this created ISO/TC 307, Blockchain and Distributed Ledger Technologies, with Australia holding the secretariat. Verdian's slides give October 2016 for ISO approval; the one-month gap is a detail, but we note it. ^[17][18]

The 2016 proposal document was hosted on remitt.com, and this is not a coincidence: Companies House shows that Quant Network Ltd was incorporated on 28 September 2015 under the name Remitt Ltd and renamed on 2 June 2017. Verdian went on to convene the committee's interoperability group (SG7, later WG7) and his slides show the committee's first plenary in Sydney in April 2017. He is the originator of the proposal, not the chair of the committee, and ISO/TC 307 is a standards body with dozens of national members, not a Quant project. ^[17][13][19]

Data aggregators also list Dr Paolo Tasca, a UCL academic, as a co-founder. We could not confirm this against a primary Quant or Companies House source, so treat it as unverified. ^[46]

The token sale and the burn

Quant sold QNT in two rounds in 2018, run by Quant Network AG in Zug, Switzerland: a pre-sale from 19 March to 1 April and a public token generation event from 2 to 30 April. Of 31 million tokens offered to the public, 9,964,259 were sold, raising about 11 million US dollars; the sale excluded US persons and residents of mainland China. On 14 September 2018 the company burned 9,545,765.95 unsold tokens, leaving a total supply of 14,612,493.08 QNT. Chapter 6 shows how these numbers reconcile with what Etherscan displays today. ^[12][9]

Corporate structure

The operating company is Quant Network Ltd, company number 09798383, a private limited company registered at 20-22 Wenlock Road, London, with SIC codes for software publishing and IT consultancy. Since November 2019 it has sat under a holding company, now called Quant Group Corporation Ltd (formerly Quant Network Holdings Ltd). ^[13][15]

The ownership trail is worth a close look. Companies House records Gilbert Verdian as the person with significant control of the holding company from its incorporation in November 2019 until 1 April 2022. On that date control passed to "Ogier Global Trustee (Jersey) Limited as Trustee of Goulding Trust," which holds 75 percent or more of the shares and voting rights and the right to appoint directors. Who the beneficiaries of that Jersey trust are is not public. ^[16]

Governance and financial transparency

There is no foundation, no DAO and no on-chain governance. QNT "carries no governance rights," token holders have no vote on technical or organizational matters, and the company has published no plan to hand control to token holders. Decisions about the product, the fee schedule and the token's role are made by Quant Network Ltd and its directors. At the time of writing Companies House listed Gilbert Verdian as the only current director of Quant Network Ltd, and Verdian, Guy Dietrich, Kornelis Smit and David Yates as directors of the holding company. The Blockworks filing names a different set of directors (Colin Paterson, Neil Smit, Rosalind Singleton) and a Chief Product Officer, Martin Hargreaves; we could not confirm those names against the register, so treat them as not verified from a primary source. ^[12][52][53]

Financial disclosure is what UK company law requires of a small private company and little more. The filing history shows "total exemption full accounts" (the small-companies regime, unaudited) for the financial years ending September 2020 through September 2024, and the first set of ordinary "full accounts," for the year to 30 September 2025, filed on 6 July 2026. There are no quarterly reports, no treasury dashboard and no public revenue figures of the kind that, for example, foundations behind other networks publish. The brief says "lack of public financial reporting"; the precise statement is that reporting exists only in statutory filings. ^[14][12]

5. The technology, explained simply

An API gateway, not a chain

Most of the coins on this site are networks with their own consensus and validators. Overledger is different: it is software that Quant hosts. The official documentation describes three foundations. The Gateway authenticates every client, enforces policy and routes requests. Connectors translate those requests into the native RPC of each blockchain and spread them across pools of nodes. The Fusion Rollup is the one part that is itself a ledger. On top sit Flow Apps, multi-step business workflows, and the Overledger Firewall. ^[1]

The analogy that works best is a universal travel adapter. The application plugs into one socket; Quant's adapter handles the different plug shapes and voltages of each chain. The developer never runs an Ethereum node, a Solana validator or a Fabric peer. Instead the Gateway routes to Quant-managed nodes, to public nodes from whitelisted providers, or to private nodes a customer registers. For public networks, "the amount of QNT staked against the node" is one of the factors in routing decisions. ^[3]

Flow Apps are packaged workflows such as deploying a contract, bridging or executing a corporate payment. Technically each one is a finite state machine the client walks step by step, with a prepare-sign-execute pattern so that private keys never leave the customer. Individual steps can be gated behind a payment using the x402 protocol, and "apps are free to price in QNT, a stablecoin (USDC, USDT, ...), or any other ERC-20." This is the clearest statement in the current documentation about where the token sits in day-to-day use: as one payment option among several. ^[4]

The Fusion Rollup

A rollup bundles transactions off-chain and posts compressed data to a parent chain. Fusion, which Quant calls "Layer 2.5," is built on the OP Stack, the same open-source optimistic rollup framework used by Base and Optimism, but with a twist: instead of deriving its state from one parent chain it reads deposits and messages from several connected chains in a deterministic rotation. Transaction data is posted to a single private permissioned Hyperledger Besu chain run by Quant; only state roots are posted to the other connected chains. Quant explains the choice of an optimistic design over zero-knowledge proofs on cost grounds: validity proofs would have to be posted to every connected chain. ^[2]

Two properties matter for risk. First, withdrawals are not instant: because the design is optimistic, a withdrawal must be proven on the destination chain and then wait out a dispute window in which a challenger can show the state root is wrong. The docs call the window "the load-bearing security property." Second, the Blockworks transparency filing states that Quant will act as the sequencer, so one company orders every Fusion transaction. The documentation also notes that the Fusion RPC is a curated subset of Ethereum's: a permissioned API key is required, and unauthorised calls are rejected. ^[2][12]

Fusion's mainnet went live on 2 June 2026, connected, according to Quant's announcement as reported by trade press, to 74 blockchain networks. The number is the company's; we found no independent count. The testnet connected Ethereum Sepolia, Polygon Amoy and Quant's own permissioned Besu testnet, and the public docs list the testnet chain ID (73073) but a placeholder for the mainnet one. ^[36][2]

Closed source and patents

Here is the criticism that follows Quant everywhere: there is no public repository of Overledger's code. Coin Bureau's review puts it plainly: "Quant Network is not open source and much of the technology used in its products is patented, requiring licensing to use." Quant has disclosed at least one granted patent, Japanese patent 7273053 for "Blockchain Communications and Ordering," announced in August 2023, and says other elements are patent pending. Reports around the Fusion launch speak of three patent families with grants in the US, Europe and Japan, which we could not verify against patent registers. ^[39][38][37]

What is open: the QNT token contract itself. Etherscan shows a verified "Exact Match" between the deployed bytecode and the published Solidity source, a plain StandardToken compiled with solc 0.4.21. No security audit is submitted on Etherscan; Blockworks cites an EtherAuthority review finding the contract has no owner controls, meaning nobody can mint more or freeze balances. The Fusion Rollup's bridge contracts are standard OP Stack contracts, which are open source upstream. ^[9][12][2]

6. The token

Supply, from mint to burn

QNT is an ERC-20 token with 18 decimals at contract address 0x4a220E6096B25EADb88358cb44068A3248254675 on Ethereum. The contract was created in 2018 with 45,467,000 tokens: 31 million for the public sale and a company reserve of 14,467,000. Only 9,964,259 were sold. On 14 September 2018 Quant burned 9,545,765.95 unsold tokens, and the total supply has been 14,612,493.08 QNT since. No tokens have been created after the sale, and the contract has no function to mint more. ^[9][12]

Etherscan's display confuses many readers, so here is the reconciliation. The explorer shows a "max total supply" of 45,467,000, a total supply of 24,158,259.03, and the token contract address itself as the largest holder with about 9.55 million QNT. Those three numbers fit one story: 14,612,493.08 plus 9,545,765.95 equals exactly 24,158,259.03, and the contract address holds roughly the burned amount. Our reading of the on-chain data is that the "burn" was executed by sending the unsold tokens to the token contract, where nothing can ever move them, rather than by calling a function that reduces the counter. Blockworks describes the 45.467 million figure as a contract-level artefact. The economically meaningful number is 14.6 million. In our own check through a public Ethereum node, the contract's totalSupply() function returned 45,467,000 QNT and the token contract address held about 9.55 million QNT, which matches this reading; CoinGecko reports a total supply of 14,612,493. We could not retrieve Etherscan's own page (it blocks automated access), so the 24,158,259.03 figure and the split of the remaining difference between 45.467 million and the burn are taken from the sources above and are not verified by us. ^{[9][10][12][11]}

Source: ^{[9][10][11][12]}

Who holds it

The post-burn allocation was roughly 9.9 million to public buyers, 2.6 million company reserve, 1.3 million founders and 651,000 advisors, with a 12-month vesting period for managers and staff. Blockworks notes that company holdings fell from about 4.65 million at the burn to about 68,000 QNT today and that Quant has not explained how; the fair inference is that the company sold or distributed its reserve over the years, which is also how it has funded itself beyond the 11 million dollar raise. ^[12]

Concentration among ordinary holders is modest. Setting aside the contract address, the largest wallets on the holder chart hold about 600,000 QNT each, roughly 4 percent of the real supply, and the first labelled exchange wallet (Binance) appears at about 553,000. Note that Etherscan's percentage column divides by 45.467 million, so every percentage it shows should be multiplied by about three. ^[10]

What the token is for

Utility has changed shape over the years, and this is where the most outdated claims circulate. In the early years an Overledger licence was required and payable in QNT; Blockworks records a production licence of 100 pounds per year in QNT, with sandbox access free. Older explainers describe a "Quant Treasury" that converted fiat licence payments into QNT and locked the tokens for the licence term; we found this described only in secondary sources and in no current primary document, so treat the lock-up mechanism as historical and unverified. ^[12][45]

At the time of writing the primary sources describe three roles. First, payment: platform fees can be paid in US dollars or by subscription in QNT, and Flow App steps gated by x402 can be priced in QNT or in a stablecoin at the app developer's choice. Second, staking: the Gateway exposes a "stakes" API "for locking QNT to earn rewards and unlock higher capacity tiers," staked QNT influences which public nodes receive traffic, and Blockworks says trusted-node operators will stake QNT; the official staking chapter is marked "under construction" pending a testnet staking experience in the Quant Connect dashboard. Third, Fusion: Blockworks states the rollup "will use QNT for gas and execution fees." ^{[12][4][5][3][6]}

What QNT does not do: it confers no governance rights, no dividends or interest, no share in Quant's revenue and no claim on the company. Platform fees paid in dollars are ordinary corporate revenue of Quant Network Ltd. A "community treasury" smart contract handles QNT payments from users to gateways; Blockworks notes its upgradeable proxy has admin keys whose multisig configuration is not disclosed. ^[12]

7. Real adoption

We separate three kinds of evidence: participation that is documented in a primary report or filing, announcements and signed engagements that are not yet live, and narratives we could not verify. Note that even the verified items are pilots, experiments or contracts, not production networks carrying the public's money.

8. The ISO 20022 connection

ISO 20022 is a messaging standard for financial institutions: a shared dictionary and format for payment instructions, used by SWIFT and by domestic payment systems. It is a standard for how banks describe a payment, not a certification that a blockchain or a company can earn. Our ISO 20022 explainer covers the standard itself.

Quant's relationship with ISO is real but it concerns a different standard. Verdian originated the proposal that became ISO/TC 307, the blockchain and distributed ledger committee, and convened its interoperability working group. That committee produces vocabulary, reference architecture, governance and interoperability documents for blockchains; it does not own ISO 20022, which belongs to a separate committee (TC 68, financial services). Being involved in TC 307 says nothing about ISO 20022 compliance. ^[17][18]

There is a genuine, if indirect, ISO 20022 link in Quant's current work. The 2015 proposal already called for "interoperability and compatibility with existing financial standards," and the two US payment systems Quant has been selected to connect tokenized deposits to both use the standard: TCH describes RTP's "rich ISO 20022 data for real-time reconciliation" and says CHIPS "supports data-rich ISO 20022 messaging." An orchestration layer that moves value between a tokenized deposit ledger and RTP has to speak ISO 20022 on one side. The UK RLN prototype similarly connected to Open Banking and a simulated RTGS. ^{[17][34][35][32][26]}

9. Ecosystem and competitors

Quant competes in institutional interoperability: connecting ledgers to each other and to legacy systems. Its ecosystem is correspondingly small and enterprise-shaped. There is no large open developer community, no DeFi built around QNT and no public explorer for Overledger traffic. Instead there are consultancies and vendors it has worked alongside: UST in Rosalind, R3, DXC and Coadjute in the UK RLN, and Oracle. ^[21][25][28]

The sharpest crypto-native competitor is Chainlink's CCIP, which also sells secure cross-chain messaging and token transfers to institutions, advertises "80+ networks connected," and cites a Swift pilot with UBS Asset Management and work with ANZ. LayerZero offers a comparable messaging layer and lists PayPal, Tether and Paxos among its partners. Both are far larger by developer adoption and on-chain volume, and both are at least partly open source. ^[48][49]

Quant's enterprise competitors are also its partners. R3's Corda was the shared ledger in the UK RLN while Quant provided orchestration on top; Hyperledger Besu and Fabric, the open-source ledgers of LF Decentralized Trust, were the ledgers simulated in Rosalind and the data-availability layer under Fusion. A bank can buy Corda or run Besu without Quant. Quant's bet is that banks will want a neutral layer above all of them. ^{[25][21][2][31]}

The non-crypto incumbents are the payment rails themselves. SWIFT, TCH and national RTGS operators can add tokenization features internally, and TCH's choice to contract Quant rather than build is the strongest signal in Quant's favour so far. Where does this leave Quant? A credible, repeatedly selected vendor in a niche where selection decisions are made by committees of banks, with patents and regulatory relationships as its moat and a small ecosystem as its weakness. ^[32][38]

10. Regulation and legal history

Quant Network Ltd is an ordinary UK private company; it is not, as far as public registers show, authorised by the Financial Conduct Authority, and nothing in its business as a software vendor to banks requires it to be. The token was issued by a Swiss entity, Quant Network AG in Zug, and the 2018 sale excluded US persons and mainland China residents and applied KYC and AML checks to buyers. ^[13][12]

We found no enforcement action, lawsuit or regulatory statement naming QNT or Quant in the US, UK or EU at the time of writing. QNT has been listed on Coinbase since June 2021, on Kraken (including a EUR pair) since 2022, and on Binance.US since November 2022 per the Blockworks filing, which suggests those exchanges' legal teams were comfortable listing it through the period when US regulators were most aggressive. This is an absence of bad news rather than a positive ruling: no court or regulator has classified QNT. ^[40][41][12] QNT is also not among the examples of digital commodities in the SEC's March 2026 interpretive release; the release says an asset need not be listed to be one, so this is not a classification either. ^[50]

Two claims deserve caution. Several exchange blogs state that FINMA "regulates QNT as a utility token"; the one we checked cites no FINMA document, and FINMA does not regulate individual tokens so much as issue guidance on how it classifies them. We treat the claim as unverified. Second, a MiCA white paper for QNT exists, but it was not written by Quant: ESMA's interim register lists one drawn up by the exchange Bitstamp Europe and notified to Luxembourg's CSSF (record dated 2026-05-18). It is an exchange's disclosure document, not a classification by the regulator, so check QNT's treatment with the exchange you use. ^[45][11][51]

Security incidents involving QNT have been at exchanges, not in the token: the LCX hot wallet hack of January 2022 took 669 QNT among other assets, and the Bitrue hack of April 2023 included QNT among about 23 million dollars stolen. Neither touched the QNT contract or Quant's funds. ^[12]

11. Key risks

Single-company risk. Overledger, the Fusion sequencer, the data-availability chain, the fee schedule and the token's utility are all controlled by Quant Network Ltd. If the company changed strategy, was acquired, lost a key contract or failed, there is no community that could keep the system running. QNT holders have no governance recourse. ^[12][2]

Closed source and limited verifiability. You cannot inspect Overledger's code, run your own gateway or audit the sequencer. Trust rests on contracts and reputations, which is normal in enterprise software but removes the main thing that makes public blockchains checkable. ^[39][2]

Utility is optional. Platform fees can be paid in dollars; app developers may price steps in stablecoins; staking is not yet live. Demand for QNT therefore depends on choices Quant and its customers make, not on a protocol rule. The company could strengthen or weaken the token's role at any time. ^[12][4][6]

Opaque ownership and thin reporting. The ultimate owner is a Jersey trust whose beneficiaries are not public; accounts were filed under the small-company exemption until 2025; there is no treasury report. Investors in the token are, in effect, exposed to the company's success without any of a shareholder's information rights. ^[16][14][12]

Pilot-to-production gap. Rosalind and the UK RLN were experiments that ended with reports. The TCH network is scheduled, not live. Enterprise projects slip, and selection as a vendor is not the same as revenue. ^[22][27][32]

Fusion is new. An optimistic rollup that posts data to a single private chain operated by the same company that runs the sequencer is an untested design under adversarial conditions; withdrawals also wait for a dispute window. ^[2]

Ethereum dependence and self-custody friction. QNT inherits Ethereum's fees and congestion, and every self-custody transfer needs ETH for gas. Sending QNT on the wrong network or to the contract address is irreversible. ^[42][9]

Key-person risk. The founder is the public face, the ISO link and the chief executive. ^[19][12]

Market risk. QNT is a small-supply token with a history of sharp moves; the holder base is about 183,000 addresses. ^[10]

This page is educational and is not investment advice.

12. Bull case vs bear case

The bull case runs like this. Large US banks are backing tokenized deposits as a way to put commercial bank money on-chain, and The Clearing House, the bank-owned operator of RTP and CHIPS, chose Quant in September 2026 to provide the interoperability and orchestration layer of its On-Chain Money Initiative. That followed UK Finance picking Quant as one of two technology partners for the 2024 Regulated Liability Network experiment, and the BIS and Bank of England using Overledger in Project Rosalind. If the TCH network goes live as scheduled in the first half of 2027 and other markets follow, Quant could become embedded infrastructure, and Quant says its Fusion Rollup will use QNT, a fixed-supply token of about 14.6 million units, for gas and execution fees. Supporters add that patents and years of work with central banks and banking bodies are hard for a newcomer to replicate. ^{[33][32][25][22][12][38]}

The bear case starts from the same facts. Quant's wins are vendor contracts, and vendors get replaced; the banks that own TCH could insist on open standards or build in-house, and Chainlink's CCIP and LayerZero already have far larger footprints. The token is loosely coupled to the business: platform fees can be paid in dollars, staking is not live, QNT carries no governance rights, and the company has no obligation to route value to holders. Closed source, a Jersey trust as ultimate owner and small-company accounts mean outsiders cannot verify the health of the business the token depends on. And none of Rosalind, the RLN experiment or the TCH selection is yet a production network carrying customer money. ^{[12][48][6][16][14][22][27][32]}

Both cases rest on verifiable facts; they differ on whether vendor selections by banking bodies will turn into production use that routes demand to QNT. The reader decides. What both sides can monitor: whether the TCH network goes live in the first half of 2027 as scheduled, whether Fusion fees are visibly paid in QNT, and whether QNT staking is released. ^[32][2][6]

Scores follow the rubric used for every coin on this site; the rationale for each category is shown in the card.

14. How to buy and store

Before the exchange and wallet list, five QNT-specific pitfalls. All of them follow from one fact: QNT is an ERC-20 token that lives inside a smart contract on Ethereum. ^[9][43]

1. You need ETH to move QNT from your own wallet. Every Ethereum transaction, including a token transfer, consumes gas, and "gas fees have to be paid in Ethereum's native currency, ether (ETH)." A wallet holding only QNT cannot send it. Before withdrawing QNT to a self-custody wallet, send a small amount of ETH to the same address, or you will own tokens you cannot move until you do. On an exchange this is invisible because the exchange pays the gas and charges you a withdrawal fee. ^[42][44]

2. Choose the Ethereum (ERC-20) network on withdrawal. Some exchanges list several networks for a token. QNT's canonical token is on Ethereum; a network selection such as BNB Smart Chain or Polygon on a withdrawal screen sends a different representation, or nothing your wallet can see. Pick Ethereum (ERC-20) unless you know exactly why you are choosing otherwise, and confirm the receiving wallet supports Ethereum tokens. ^[44][11]

3. Never send QNT to the token contract address. The address 0x4a220E6096B25EADb88358cb44068A3248254675 identifies the QNT contract; it is not a wallet. Ethereum's own documentation warns that the ERC-20 transfer function "is not designed for depositing tokens to contracts." Tokens sent there cannot be recovered; the roughly 9.55 million QNT sitting at that address, most of it the 2018 burn, show exactly what happens. ^[9][43][10]

4. No memo or destination tag. Unlike XRP, XLM or HBAR, Ethereum addresses have no memo field. Each exchange deposit address is unique to you, so there is nothing extra to copy; if a form asks for a memo when depositing QNT, you are on the wrong network or the wrong coin. ^[43]

5. Verify the contract address from an official source. Anyone can deploy a token called "Quant" or "QNT." When adding QNT to a wallet, take the contract address from Etherscan's verified token page or from a reputable aggregator, and compare the full string, not just the first and last characters. MetaMask's guidance is to check the address on a block explorer or listing site and to "consider using test transactions before sending large sums." ^[9][44][11]
