QNT is an ERC-20 token on Ethereum [1], which means you can hold it either on an exchange, which keeps the keys for you, or in a wallet where you hold the keys yourself. Each choice has trade-offs. This guide explains them in plain English, covers seed phrase basics, and lists the scams that catch most people. It is general security education: it is not financial advice, we do not recommend any product, and this page contains no affiliate links.
Keys, not coins
A crypto wallet does not 'contain' tokens in the way a physical wallet contains cash. Your tokens are recorded on the blockchain, and what you actually hold are the cryptographic keys that authorise moving them. Ethereum.org describes a wallet as the thing that gives you control over your account and lets you sign in to applications, read your balance and send transactions [2].
Whoever controls the private keys controls the tokens. That single idea explains the whole exchange-versus-self-custody debate: on an exchange, the exchange controls the keys and you hold a claim against the exchange; in self-custody, you control the keys and nobody can help you if you lose them.
Option 1: leaving QNT on an exchange (custodial)
When you buy QNT on an exchange and leave it there, the exchange holds the keys. Advantages: it is simple, there is nothing to back up, and many exchanges offer password resets and customer support if you lose access.
Disadvantages: you depend on the exchange's security and solvency; accounts can be frozen, hacked or suspended; and what you hold is, in effect, a record on the exchange's books. Exchange failures have happened in this industry's history, so it is sensible not to leave more on an exchange than you are comfortable risking. Check the exchange's regulatory status in your country. In the UK, the Financial Conduct Authority warns that if you invest in crypto you should be prepared to lose all the money you put in [3].
If you do keep QNT on an exchange, turn on two-factor authentication with an authenticator app or security key rather than SMS, use a unique password from a password manager, and enable withdrawal address allow-lists if offered. The UK National Cyber Security Centre's general guidance on strong passwords and two-step verification applies directly [4].
Option 2: self-custody with a hardware wallet
A hardware wallet is a small dedicated device that stores your private keys offline and signs transactions inside the device, so the keys are not exposed to your computer or phone. For larger holdings that you do not plan to trade often, many people prefer this approach.
Because QNT is an ERC-20 token, any wallet that supports Ethereum and ERC-20 tokens can hold it. Before buying a device, check the manufacturer's current supported-asset list to confirm QNT support, and buy only from the manufacturer or an authorised reseller. A device bought second-hand or from an unknown marketplace seller could have been tampered with.
Trade-offs: you are fully responsible. If you lose the device you can recover with your seed phrase; if you lose the seed phrase and the device, nobody can recover your tokens for you. If someone else obtains your seed phrase, they can take everything.
Software wallets and the middle ground
Software wallets, such as browser extensions or mobile apps, are self-custody wallets where the keys live on an internet-connected device. They are convenient for frequent use and for connecting to apps, but they are exposed to malware and phishing in ways a hardware wallet is not. A common pattern is to keep a small spending balance in a software wallet and long-term holdings elsewhere. Ethereum.org's wallet and security pages are good neutral starting points [2][5].
Seed phrase basics
When you set up a self-custody wallet, it gives you a recovery phrase, usually 12 or 24 words, often called a seed phrase. This phrase can regenerate all the keys in the wallet. It is the master key. Treat it accordingly.
- Write it on paper or a purpose-made metal backup at setup. Do not photograph it, store it in cloud notes, email it or put it in a password manager you cannot fully trust.
- Never type it into a website, a chat, a 'support' form or an app other than your wallet's own recovery screen. Legitimate support teams never need it. Ethereum.org's security guidance makes the same point about unsolicited support contacts [5].
- Keep at least one backup in a separate safe place, such as a fireproof home safe or a safe-deposit box, so a fire, flood or theft at home does not wipe you out.
- Do a test recovery with a small amount before you move your main holding. Confirm you can restore from the phrase.
- Think about inheritance: if something happened to you, could a trusted person find and use your backup? Write instructions separately from the phrase itself.
- Optional extra: some wallets support a passphrase on top of the seed phrase. It adds protection but is one more thing you can lose, so only use it if you understand it.
A safe way to move QNT
When you first send QNT to a new wallet, first double-check the destination address character by character, because blockchain transactions cannot be reversed. Send a small test amount first. Wait for it to arrive. Then send the rest. Make sure you are sending on the Ethereum network, since QNT's ERC-20 contract is on Ethereum [1]; some exchanges support other networks for other assets, and sending to the wrong network can lose funds.
To check you have the real token, compare the contract address with the one on Etherscan's QNT page [1] and with the contract address shown on our supply dashboard. Fake tokens with copied names are common.
Common scams to recognise
The FCA's consumer guidance on crypto is a useful reality check on risks, including scams [3].
- Fake support: someone messages you offering help and asks for your seed phrase. Real support never will.
- Phishing sites and fake wallet apps: always type the address yourself or use a bookmark you made earlier. Check app-store publishers carefully.
- Fake airdrops and 'claim' links: unexpected tokens or links urging you to connect your wallet to claim a reward are a classic trap.
- Malicious token approvals: connecting your wallet to a site and approving a token spend can give that site permission to move your tokens later. Review and revoke old approvals using an approval-management tool, and be wary of approving 'unlimited' amounts.
- Pressure and promises of guaranteed returns: legitimate projects do not guarantee profits.
A practical checklist
None of this guarantees safety, and this page is not advice tailored to your circumstances. Whatever you choose, remember that QNT carries no governance rights and no claim on Quant's revenue [6], that crypto-assets are volatile, and that this site makes no price predictions.
- Decide how much you are holding and what you can afford to lose.
- Use unique passwords and app- or key-based two-factor authentication everywhere.
- For long-term holdings, consider a hardware wallet bought directly from the maker.
- Back up your seed phrase offline, in two places, and never share it.
- Test with a small transfer first.
- Verify the QNT contract address.
- Revisit your setup once a year.
Frequently asked questions
Is it safer to keep QNT on an exchange or in a hardware wallet?
They carry different risks. An exchange holds your keys, so you depend on its security and solvency. A hardware wallet gives you the keys but also the responsibility for backups. Many people keep small amounts on exchanges and long-term holdings in self-custody. This is general information, not advice.
What is a seed phrase?
A 12- or 24-word recovery phrase that can regenerate all the keys in a wallet. Anyone who has it can take your tokens, so never share it or type it into a website, and keep offline backups.
Can a hardware wallet hold QNT?
QNT is an ERC-20 token on Ethereum, so wallets supporting Ethereum and ERC-20 tokens can hold it. Check the manufacturer's current supported-asset list before buying.
What network is QNT on?
The QNT ERC-20 contract is on Ethereum mainnet at 0x4a220e6096b25eadb88358cb44068a3248254675. Verify the address on Etherscan before transacting.
