Since 2015, Changelly has been quietly processing crypto swaps in the background while flashier exchanges grabbed headlines. It doesn’t have the trading depth of Binance, the brand recognition of Coinbase, or the Web3 native appeal of MetaMask. What it has is a decade of doing one thing well: letting people swap one cryptocurrency for another, quickly, without the friction of a full exchange account.
But longevity in crypto isn’t the same as quality. The space moves fast, and a service that was cutting-edge in 2015 can feel dated and overpriced by 2025. So the real question is whether Changelly has kept up — or whether newer competitors like ChangeNOW, SimpleSwap, and SideShift have quietly eaten its lunch.
I’ve been using Changelly on and off since the early days, and I’ve done a thorough review of where it stands right now — the rates, the fees, the user experience, the support, and the controversies that have followed it over the years. Here’s the honest picture.
What Is Changelly?
Changelly is a non-custodial cryptocurrency exchange service founded in 2015, originally developed by the team behind the MinerGate mining pool. It is headquartered in Prague, Czech Republic, and has processed hundreds of millions of dollars in crypto swaps over its operating history, making it one of the longest-running instant swap services in the industry.
The platform allows users to swap between cryptocurrencies without creating a traditional exchange account. You select your input and output currencies, enter a destination wallet address, send your funds, and receive the converted asset — directly to your wallet. Changelly acts as the intermediary, aggregating liquidity from exchange partners to execute the swap.
Changelly also offers a DEX aggregator product (Changelly DEX) for decentralized swaps, a fiat on-ramp for buying crypto with a card, a PRO trading interface for more advanced users, and a business API used by a wide range of wallets and platforms. It supports over 500 cryptocurrencies and has built integrations with major hardware wallets including Ledger and Trezor, which surface Changelly’s swap functionality directly within those devices’ companion applications.
Key Features of Changelly
1. Instant Crypto Swaps — No Full Account Required
Like most instant swap services, Changelly’s core offering is the ability to convert one cryptocurrency to another without the full onboarding process of a traditional exchange. You don’t need to go through KYC verification to initiate a standard swap, and you don’t maintain a balance on the platform — your funds arrive, get swapped, and leave to your wallet in a single flow.
This is the feature that built Changelly’s reputation a decade ago, and it still works. For users who want to convert assets without maintaining another exchange account, the process is fast and straightforward.
That said, “no KYC” has some nuance at Changelly that’s worth being transparent about. The platform does conduct AML screening on transactions. If a swap triggers a compliance flag — based on the source or amount of funds — Changelly may pause the transaction and request identity verification before proceeding. This has surprised some users who expected a fully frictionless, anonymous experience. It’s standard practice for a compliant swap service, but it’s worth knowing upfront rather than discovering mid-transaction.
2. Floating and Fixed Rate Options
Changelly offers two swap modes:
Floating Rate: The rate shown when you initiate a swap is an estimate based on current market conditions. The actual rate applied when your funds arrive and the swap executes may differ slightly. Under calm market conditions, the variance is usually small. During high volatility, it can be more significant.
Fixed Rate: You lock in the exchange rate shown at swap initiation. Whatever the market does while your deposit is in transit, the rate you were quoted is the rate you receive. Fixed rate swaps carry a slightly higher fee to account for Changelly absorbing the rate risk, but they deliver certainty — particularly valuable when swapping larger amounts where a 1–2% rate movement represents real money.
For small, routine swaps during stable market conditions, floating rate is fine. For larger amounts or when market conditions are choppy, paying the premium for a fixed rate is almost always the smarter call.
3. Wide Cryptocurrency Coverage
Changelly supports over 500 cryptocurrencies, covering all the major assets — Bitcoin, Ethereum, XRP, Litecoin, Solana, Cardano, Avalanche, Polkadot, and many more — alongside a substantial selection of mid-cap and smaller tokens. The breadth is solid, though it’s worth noting that ChangeNOW currently supports over 900 assets, which gives that platform a meaningful edge for users dealing with more obscure tokens.
For the vast majority of common swap use cases, Changelly’s 500+ asset selection is more than sufficient. Where it occasionally falls short is for users trying to move between niche tokens that haven’t made it onto Changelly’s supported list.
4. Changelly PRO
Changelly PRO is the platform’s more advanced trading interface, offering a traditional order book experience with limit orders, real-time charts, and a broader range of trading pairs for users who want more than instant swaps. It’s positioned as the bridge between Changelly’s simple swap roots and a more full-featured trading environment.
In practice, Changelly PRO is a functional but not particularly competitive trading interface when measured against dedicated exchanges like Kraken or Binance. Experienced traders will find it adequate for basic execution but lacking the depth, liquidity, and advanced order types that professional trading demands. It’s more useful for Changelly’s existing user base who occasionally wants more control than the basic swap interface provides, rather than as a destination for serious traders.
5. Changelly DEX
Changelly’s DEX product is a decentralized exchange aggregator that routes swaps through decentralized protocols rather than centralized liquidity sources. It supports EVM-compatible chains and allows users to swap tokens in a fully non-custodial way using their connected Web3 wallets — no centralized intermediary involved.
For DeFi-native users who want decentralized execution with Changelly’s familiar interface layer, the DEX aggregator is a useful addition. It’s not breaking new ground compared to dedicated DEX aggregators like 1inch, but having it integrated within the Changelly ecosystem gives the platform more relevance to Web3 users than a pure centralized swap service would.
6. Fiat On-Ramp
Changelly allows users to buy cryptocurrency directly with a credit card, debit card, or bank transfer through partnerships with fiat gateway providers. The feature covers a wide range of countries and payment methods, making it one of the more accessible crypto entry points for users who are starting from fiat.
As with all card-based crypto purchases, fees are higher than buying on a centralized exchange through a bank transfer. The convenience tradeoff is real though — for someone who wants to buy $100 in Bitcoin without creating a full exchange account, Changelly’s fiat on-ramp offers a fast path.
7. Hardware Wallet Integrations
One of Changelly’s more distinctive distribution advantages is its deep integration with hardware wallet companions. Changelly’s swap functionality is available directly within Ledger Live and Trezor Suite — meaning users of those hardware wallets can initiate swaps without leaving their device’s management software.
For hardware wallet users who prioritize security and want to stay within their trusted software environment, this integration is genuinely convenient. It’s a partnership that reflects real enterprise relationships rather than just a marketing claim, and it has helped Changelly maintain relevance with security-focused crypto holders.
8. Changelly Business API
Changelly offers a business API used by a significant number of wallets, platforms, and crypto services to power their in-app swap features. If you’ve swapped tokens inside a wallet app and had it work seamlessly without knowing how, there’s a reasonable chance the Changelly API was behind it.
The API is well-documented and has a long track record of reliability, which matters for businesses building production integrations. It’s a less visible but commercially important part of Changelly’s operation.
9. Changelly Widget
For website owners and developers who want to embed swap functionality into their own pages without a full API integration, Changelly offers an embeddable widget. It’s a lower-friction option for smaller projects that want to offer swap functionality to their users.
Changelly Fees: The Part That Needs Honest Scrutiny
Let’s talk about fees, because this is where Changelly draws the most criticism — and where some of that criticism is legitimate.
Changelly charges a service fee of approximately 0.25% for floating rate swaps and a higher rate for fixed rate swaps — typically around 0.5%. On top of this service fee, there are network fees (miner or validator fees) for the outgoing blockchain transaction, which vary depending on the network involved.
At face value, a 0.25% service fee sounds reasonable and competitive. The complication is that Changelly also applies a spread on top of the stated fee — a difference between the rate you’re quoted and the actual exchange rate available in the market — which means the total effective cost is often higher than the nominal fee suggests.
When you compare the rate Changelly shows you to the spot price on CoinGecko or CoinMarketCap for the same pair, the gap between the two — spread plus service fee combined — can range from 0.5% to 2% or more depending on the pair, the amount, and market conditions. For major pairs like BTC/ETH under normal conditions, the all-in cost is usually closer to the lower end. For less liquid pairs or during volatile markets, it can climb.
This isn’t unique to Changelly — all instant swap services embed their costs in the rate — but Changelly has historically been on the higher end of the cost spectrum among its direct competitors. Users who compare rates across multiple platforms (which takes about sixty seconds using any rate comparison site) frequently find ChangeNOW or SimpleSwap offering better effective rates on the same pair.
The honest bottom line: Changelly’s fees are not the most competitive in the instant swap category. For users who value the platform’s reputation, integrations, and user experience and are making modest swaps, the premium is acceptable. For users who are cost-sensitive or swapping large amounts regularly, comparing rates before every transaction is worth the thirty seconds it takes.
Changelly Security: A Decade of Operation — And One Major Controversy
Security is always the central question, so let’s cover it fully — including the part that’s uncomfortable.
Non-custodial by design. Like other instant swap services, Changelly doesn’t hold user balances in the traditional sense. Funds arrive at a swap deposit address, the conversion is executed, and the output is sent to the user’s specified wallet. This significantly reduces the custodial risk compared to a full exchange holding user funds.
Established track record. Changelly has been operating since 2015 without a major platform-level security breach. A decade of clean operation in a high-risk environment is a meaningful signal of operational competence.
AML compliance. Changelly conducts AML screening and cooperates with law enforcement requests where legally required. This is the standard for any legitimately operating exchange service and is worth knowing about.
The frozen funds controversy. Here’s the part that deserves direct discussion: over the years, Changelly has received a notable number of user reports about transactions being frozen mid-swap, funds being held pending verification, and in some cases, funds being delayed for extended periods while compliance reviews were conducted. The experiences described by affected users range from mildly inconvenient (a few days delay with eventually successful resolution) to seriously frustrating (extended holds with unclear communication from support).
To be fair, some portion of these cases likely involved transactions that genuinely triggered AML flags for legitimate compliance reasons. Instant swap services that operate globally under AML frameworks will inevitably pause transactions that match risk profiles, and not every user who experiences this is a bad actor — false positives happen. Changelly’s compliance framework appears more aggressive than some competitors, which means some ordinary users in ordinary situations will encounter friction that they don’t encounter on platforms with lighter-touch compliance.
This isn’t a reason to avoid Changelly categorically, but it is a reason to be aware that if you’re moving larger amounts or funds from certain sources, a compliance hold is more likely than on some competing services. Understanding this upfront is better than being surprised mid-transaction.
Standard user security: Changelly supports two-factor authentication for accounts and email confirmation for transactions. Enable 2FA if you create an account, and always verify deposit addresses independently before sending funds.
User Experience: What Does Swapping on Changelly Actually Feel Like?
Changelly’s interface is one of its strongest suits. The swap flow is clean, intuitive, and has been refined over years of use: select input currency and amount, select output currency, review the estimated rate, enter your destination wallet address, confirm the terms, send funds, track the transaction. The whole process from arrival to confirmation takes under two minutes for a straightforward swap.
The platform works well on both desktop and mobile browser, with a responsive design that doesn’t require a separate app for basic swapping. The Changelly mobile app is available for users who prefer a native app experience, though many users find the mobile web experience perfectly adequate.
The transaction tracking interface is transparent — showing swap status, estimated time, and transaction IDs for both the incoming and outgoing transactions so you can verify on blockchain explorers independently. For most swaps that complete without incident, the experience from start to finish is smooth and confidence-inspiring.
Where the experience degrades is in edge cases: network congestion causing unexpected delays, rate fluctuations on floating rate swaps during volatile markets, or — as discussed — AML-triggered holds. In these situations, the quality of customer support becomes the decisive factor in whether the experience ends well.
Customer support at Changelly operates primarily through live chat and email. The live chat is available on the website and is typically staffed during business hours. Response times and quality are variable — routine questions get handled reasonably well, but complex issues involving stuck transactions or compliance holds can drag on longer than users in anxious situations want. This is a consistent theme in user reviews across multiple platforms and is one of the areas where Changelly has room to meaningfully improve.
Changelly vs. ChangeNOW vs. SimpleSwap: How Does It Compare?
Changelly vs. ChangeNOW: This is the most direct comparison, and in most dimensions ChangeNOW edges ahead in 2025. ChangeNOW supports more assets (900+ vs. 500+), generally offers more competitive rates on equivalent pairs, and has a slightly cleaner reputation around customer support and transaction completion. Changelly’s advantages are its longer track record, deeper hardware wallet integrations (Ledger, Trezor), and its Changelly PRO and DEX products for users who want more than basic swaps.
Changelly vs. SimpleSwap: SimpleSwap is a leaner, more straightforward competitor with competitive rates and a clean interface. It’s a solid alternative for users who find Changelly’s rates too high or want a simpler experience without the broader feature set. Changelly’s hardware wallet integrations and PRO trading interface give it more depth for users who want it.
Changelly vs. Coinbase (Simple Conversion): Coinbase’s Convert feature is convenient for existing Coinbase users but more expensive than Changelly for most pairs. Changelly’s advantage is that it requires no Coinbase account and covers assets Coinbase doesn’t list. For Coinbase users making routine conversions within the exchange ecosystem, the convenience may outweigh the cost. For everyone else, Changelly is typically cheaper.
Changelly vs. Uniswap/DEX: For EVM-based swaps, decentralized exchanges like Uniswap or aggregators like 1inch often offer better rates than Changelly for users comfortable with DeFi. Changelly’s advantages are simplicity, cross-chain capability, and not requiring any wallet setup or gas management knowledge. The DEX path is better for experienced DeFi users; Changelly is better for users who want simplicity.
Changelly Pros and Cons
What Works Well:
- One of the longest operating histories in instant crypto swaps — running since 2015
- Clean, intuitive swap interface that’s been refined over a decade
- Both floating and fixed rate options for flexibility and certainty
- 500+ supported cryptocurrencies covering all major and most common assets
- Deep hardware wallet integrations — available natively in Ledger Live and Trezor Suite
- Changelly DEX for decentralized swap option within the same ecosystem
- Changelly PRO for users who want basic order book trading
- Fiat on-ramp for card-based crypto purchases
- Well-established business API powering integrations across many third-party platforms
- Non-custodial design — funds move through rather than being stored
- No full account required for standard swaps
Where It Falls Short:
- Fees and spreads are on the higher end compared to direct competitors like ChangeNOW
- AML compliance appears more aggressive than some competitors, with a notable history of frozen/delayed transactions reported by users
- Asset coverage (500+) trails ChangeNOW (900+) for users dealing with obscure tokens
- Changelly PRO doesn’t compete seriously with dedicated trading exchanges
- Customer support quality is inconsistent, especially for complex compliance-related issues
- Rate competitiveness should always be compared — don’t assume Changelly’s rate is the best available
Who Should Use Changelly?
Changelly is an excellent choice for:
- Hardware wallet users (Ledger, Trezor) who want swap functionality built directly into their device management software
- Occasional swappers who value a clean, simple interface and the platform’s long track record
- Users who want both centralized and decentralized swap options within a single platform ecosystem via Changelly DEX
- Fiat-to-crypto buyers who want a card-based purchase without a full exchange account
- Developers and businesses who need a battle-tested swap API with years of reliability history
- Users who prioritize platform reputation and find comfort in Changelly’s decade of operation
Changelly is less ideal for:
- Cost-conscious users who want the best available rate on every swap — always compare before committing
- Users dealing with obscure tokens that may not be in Changelly’s 500+ asset selection
- Users moving large amounts who should be aware of the possibility of AML-triggered holds
- Active traders who need a serious trading interface — Changelly PRO won’t satisfy them
- Users expecting fully frictionless anonymity — AML compliance means some transactions may require verification
Tips for Using Changelly Safely and Effectively
Always compare rates before swapping. Before confirming any swap on Changelly, spend thirty seconds checking the same pair on ChangeNOW or a swap rate aggregator. The rate difference can be meaningful, especially on larger amounts. You’re not locked in until you send funds, so comparing costs you nothing.
Choose fixed rate for anything significant. If the amount you’re swapping is large enough that a 1–2% rate swing would matter to you, pay the premium for a fixed rate. The certainty is worth more than the fee difference in most scenarios.
Verify destination addresses with extreme care. As with every crypto transaction: copy your destination wallet address, verify it character by character, and copy it again. Mistakes are irreversible. Take the extra thirty seconds every single time.
Set up 2FA if you create an account. If you register an account for access to Changelly PRO or to track swap history, enable two-factor authentication immediately using an authenticator app. Don’t skip this.
Be aware of the AML landscape before large swaps. If you’re planning to swap a substantial amount or funds that have moved through multiple wallets, be mentally prepared for the possibility of a compliance review. It doesn’t mean you’ve done anything wrong — it means automated systems flagged the transaction for review. Having your identification documents ready and knowing that support is reachable will make that experience less stressful if it happens.
Use Changelly within Ledger Live or Trezor Suite if you have one. The hardware wallet integration is one of Changelly’s genuine competitive advantages. If you’re already a Ledger or Trezor user, accessing Changelly’s swap service from within those trusted environments is both convenient and adds an extra layer of assurance about the interface you’re using.
Track your swap from confirmation to completion. Changelly provides transaction IDs for both the incoming and outgoing legs of every swap. Keep the confirmation page open or save the transaction link until you’ve confirmed receipt in your destination wallet. If anything looks delayed, you have the information you need to follow up with support promptly.
Final Verdict: Is Changelly Worth Using in 2025?
Changelly occupies a position that’s become more complicated in 2025 than it was in 2018. It’s a legitimate, well-established service with a real track record, genuine hardware wallet integrations that its competitors haven’t matched, and a platform that has clearly been developed and maintained over years rather than thrown together.
At the same time, the instant swap category has grown significantly more competitive. ChangeNOW offers more assets and generally better rates. Decentralized aggregators like 1inch offer cheaper execution for DeFi-native users. Newer entrants have built cleaner support infrastructure. Changelly’s fees sit at the high end of the category, and its history of compliance-triggered holds — while understandable in regulatory context — is a friction point that users should factor in.
The honest verdict: Changelly is a solid, trustworthy platform that’s best used when its specific advantages are relevant to your situation. If you’re a Ledger or Trezor user who wants swap functionality without leaving your hardware wallet ecosystem — Changelly is arguably your best option. If you’re a developer or business looking for a battle-tested swap API with a decade of reliability history — Changelly deserves serious consideration. If you occasionally need to convert crypto and value simplicity and platform familiarity — it’ll serve you well.
If your primary concern is getting the best possible rate on every swap, compare before you commit. Don’t assume Changelly’s quote is the most competitive — sometimes it is, often it isn’t. Thirty seconds of comparison can save real money over hundreds of transactions.
Go in with clear expectations, use its genuine strengths deliberately, and you’ll find Changelly a useful and reliable part of your crypto toolkit — just not necessarily the most cost-efficient one for every situation.
