Understanding custodial and non-custodial swaps with ChangeNOW

What ChangeNOW Is and Who Can Use It

ChangeNOW is an instant crypto exchange service. It is not a spot trading venue with order books, and it is not a self-custody wallet that stores a standing balance for customers. In a standard swap, the user chooses the asset to send, the asset to receive, and a destination wallet address.

No account is normally required to request and complete a standard crypto swap. Its terms require users to be at least 18 years old and legally able to enter an agreement. The core flow is aimed at individual crypto users who already have a wallet and can manage their own addresses, private keys, and network choices.

It is a poor fit for traders who need limit orders, candlestick charts, portfolio tools, margin products, or an exchange account history. It also does not suit anyone who needs a guaranteed execution price without reviewing the conditions of a Fixed Rate quote. The service can be convenient for a direct conversion, but it does not replace a full trading platform.

Supported Assets, Networks, and Swap Routes

ChangeNOW lists more than 1,500 crypto assets across more than 110 networks. That is broad coverage for an instant exchange, but a listed coin or token is not automatically an available route at a particular moment. Liquidity, maintenance, network conditions, and provider availability can make a route unavailable or change its limits.

Check both the asset and the selected network before creating an order. USDT on Ethereum, Tron, Solana, and other chains are different network versions of the same ticker. Native assets and bridged versions can also have different deposit addresses, contract addresses, liquidity, and receiving requirements. Use the official token contract information from your wallet or project before selecting a token.

A cross-chain swap can let a user send one network asset and receive another, but it is still an exchange order rather than a direct wallet-to-wallet bridge. Sending funds on the wrong network, to an unsupported contract, or to an address format not accepted by the route can prevent automatic completion. Recovery may be impossible or may require manual work and deductions. Check supported assets and the route-specific network labels before sending anything.

How are ChangeNOW rates and fees set?

They are built into the quoted exchange result, using network fees, liquidity-provider costs, route conditions, market pricing, and any applicable service cost. ChangeNOW does not present a simple standalone fee schedule for every swap. The practical figure to compare is the final amount shown in the receive field, not just the headline market price.

Classic Rate uses a market-based rate. The final amount received can change while the transaction is processed because market conditions and route pricing can move. Fixed Rate locks the quoted rate for the order conditions shown in the quote flow, giving more certainty on the conversion price when the transaction arrives as required. A Fixed Rate quote can still have timing and route requirements, so read the order details before sending.

Minimums and maximums are route specific and appear in the quote form before funds are sent. Enter the exact send amount, confirm the selected networks, and inspect the displayed receive amount immediately before creating the order. This is the useful final test for cost, especially on smaller swaps where network charges matter most. For more detail on quote mechanics, see rate calculation and the fees guide.

For Bitcoin transactions, ChangeNOW states a BTC network fee of 1 sat/vB. Actual transaction speed and total economics can still depend on blockchain congestion, the wallet fee selected for the incoming transaction, and the swap route.

Can ChangeNOW request KYC after a swap is submitted?

Yes. ChangeNOW can request identity verification after a swap is submitted when its AML and risk controls flag the transaction or associated activity. Routine swaps may proceed without account registration, but account-free access is not a promise that every transaction will avoid compliance checks.

A review can be triggered by risk signals related to a wallet, transaction pattern, asset, amount, jurisdiction, sanctions screening result, or information received through compliance monitoring. ChangeNOW may request identity documents and information needed to assess the transaction, such as proof of identity, proof of address, source-of-funds evidence, or an explanation of the transfer.

Funds can remain on hold while the review is underway. That creates a real tradeoff for users who expect the privacy and speed of a simple exchange flow. A user cannot assume that a completed blockchain deposit will be immediately converted or refunded if it enters review. Read verification requirements before using a route for a time-sensitive payment.

ChangeNOW restricts service in jurisdictions listed in its terms, including sanctioned and other prohibited jurisdictions. Users in major regions, including the United States, should check the current terms and local rules before use. Access from a location does not by itself confirm legal eligibility, and sanctions rules can apply regardless of citizenship or residence.

Custody, Security, and Privacy

ChangeNOW does not operate like a deposit wallet with a reusable customer balance. It uses a non-custodial exchange flow: the user sends the input asset to a unique address generated for that order, then ChangeNOW sends the output asset to the receiving address provided by the user. During processing, the user does not control the input funds.

Verify the generated deposit address and your receiving address character by character, or use trusted copy and paste tools. Save the transaction ID, order ID, blockchain hash, amount, selected networks, and timestamps. These records are essential if a deposit is delayed or support needs to trace an order. A typo in the output address can be irreversible because blockchain transfers generally cannot be recalled.

Phishing is a major practical risk. Use the official domain, do not trust sponsored search results or direct messages, and do not share wallet recovery phrases with anyone. ChangeNOW may use third-party liquidity providers and, for fiat purchases, third-party payment providers. These partners can affect route availability, pricing, and data handling.

Privacy is stronger than opening a routine trading account in the sense that a standard crypto swap normally does not require an account. It is not anonymous in every circumstance. Public blockchains expose transaction data, and a flagged order can lead to identity checks and further information requests. See privacy for the difference between account-free access and complete anonymity.

Swap Process, Mobile Apps, and Integrations

The normal web process starts with selecting the send asset and network, then the receive asset and network. Enter the amount and receiving wallet address, review the quote, create the order, and send the exact input amount to the unique deposit address. Confirm memo, destination tag, or other required payment reference where the selected asset uses one.

After the incoming transaction receives the required blockchain confirmations, ChangeNOW processes the exchange and sends the output to the wallet address entered on the order. The status page should show the order state and transaction details. Keep the browser page, order ID, and blockchain hash until delivery is complete. A delayed deposit can happen when the sending wallet uses a low network fee or when confirmations are slow.

ChangeNOW offers mobile apps for iOS and Android. The apps provide access to the swap flow on a phone, though users should still verify networks and full addresses carefully on a small screen. It also offers wallet integrations, API tools, and widgets for partners that want to add exchange functionality to their own products.

Notifications and status tracking are useful, but they do not remove the need to monitor a large or time-sensitive order. Quote changes, pending confirmations, maintenance, and missing memos can all delay completion. Test the process with a small amount before using a new network or asset pair.

Failed Swaps, Refunds, and Customer Support

A swap can fail or require manual handling when the deposited amount is below the minimum, the payment arrives after a quote condition expires, the selected network is wrong, or a required memo is omitted. A late or underfunded deposit may not match the original quote. The order may need recalculation, manual review, refund processing, or additional instructions from support.

Refunds are not automatic in every case. If a recovery is technically possible, network fees, processing costs, and any route-specific deductions can reduce the returned amount. Funds sent through an unsupported network, to the wrong address, or to a wrong contract can be unrecoverable. Recovery options are limited once funds have been sent incorrectly.

If an order is stuck, collect the order ID, deposit and payout addresses, transaction hashes, exact amount, network, timestamps, screenshots of the quote, and any memo used. Use ChangeNOW's official support channels and provide the evidence in one clear request. Its public materials do not publish a universal response-time commitment, so do not rely on support for urgent settlement deadlines.

Transaction-status communication is most useful when it shows confirmation progress, exchange processing, and payout submission separately. A blockchain payout can be sent by ChangeNOW yet remain unconfirmed in the receiving wallet for a period. For escalation steps and current contact routes, see contact support.

Who should use ChangeNOW for swaps?

It suits occasional users who want to swap across chains without opening a traditional trading account, provided they accept route-specific pricing and possible compliance checks. The large asset and network selection is a meaningful advantage for users who need a less common pair or need to move between ecosystems.

A centralized exchange can offer deeper liquidity, transparent order books, limit orders, and potentially better pricing for active traders. In return, it normally requires an account, identity checks, custody of exchange balances, and withdrawal steps. A decentralized exchange aggregator can offer direct on-chain execution from a wallet, but it may require separate bridging, gas management, token approval, and greater care with malicious tokens or contracts.

A wallet swap feature can be simpler because address handling is integrated into the wallet, though it may use an external provider and its quotes may not be the best available. ChangeNOW sits between these choices. It offers an account-free exchange flow for routine swaps, but users must accept that the provider handles the conversion temporarily, pricing is embedded in the quote, and KYC can be requested after risk checks.

Privacy-minded users may prefer the lack of routine registration, but should not treat it as a guarantee against verification. For large, urgent, or high-risk transfers, compare the final receive amount, route reliability, compliance exposure, and recovery process before committing funds.
