So you've got some crypto in one wallet, and you need it in a different coin in another wallet. You don't want to create an account. You don't want to upload your passport. You just want to swap and move on with your life. Totally reasonable.
That's exactly the pitch behind services like ChangeNOW and SimpleSwap. Both claim to be instant, non-custodial, and KYC-free crypto exchanges. Both have been around for years. And both have thousands of users who swear by them. But here's the thing: they're not identical, and the differences actually matter when real money is on the line.
I've spent way too many hours comparing these two, reading through Reddit threads from people who've actually used them (some happily, some not so much), and digging into the fine print of their policies. What I found was sometimes surprising, sometimes predictable, and occasionally a little concerning.
Let me walk you through everything.
What Are ChangeNOW and SimpleSwap, Exactly?
Both belong to the same category of crypto service: instant swap exchanges. The concept is dead simple. You pick a coin you want to send, pick a coin you want to receive, enter your destination wallet address, send your crypto, and a few minutes later the swapped coins show up. No order books. No trading pairs to figure out. No accounts necessary.
ChangeNOW has been doing this since 2017. They're registered in St. Vincent & the Grenadines and have processed... well, a lot of swaps. Their Trustpilot score sits around 4.5 out of 5 with over 10,000 reviews, which is a pretty solid number for any crypto service.
SimpleSwap launched a year later in 2018. Same basic model. Also non-custodial. Also no mandatory registration. Their review count is smaller (low thousands), but the ratings are similar.
On the surface, they look almost interchangeable. Underneath? Not quite.
Fees and Spreads: Where Your Money Actually Goes
Neither ChangeNOW nor SimpleSwap charges you an obvious, labeled "trading fee" the way Coinbase or Binance does. Instead, they make money the old fashioned way: they mark up the exchange rate. The spread between what the market says a coin is worth and what they actually give you for it? That's their cut.
This is where it gets interesting.
Independent comparisons from 2025 and 2026 have tried to pin down the actual effective cost of swapping on each platform. The numbers vary depending on who's doing the measuring and which pair you're swapping, but the general consensus looks like this:
ChangeNOW comes in around 0.7% total cost per swap. That includes the spread markup and everything else baked into the rate.
SimpleSwap lands closer to 1.0% total cost on average. Not dramatically more expensive, but when you're swapping a few thousand dollars worth of crypto, that 0.3% difference starts to feel real.
One exchange directory that tried to model these as traditional maker/taker fees estimated ChangeNOW at roughly 1.00% and SimpleSwap at about 1.21%. Again, these aren't literal order book fees. They're just ways of expressing the total cost as a comparable number.
Both platforms also pass through blockchain network fees (the gas or miner fees for actually moving coins on chain). Neither charges extra withdrawal fees on top of that, since you're sending directly to your own wallet. But the network fee itself can vary wildly depending on which chain you're using. Sending USDT on Ethereum? Expensive. Sending it on Tron? Basically free. Both platforms support multiple networks, so choose wisely.
Here's what bugs me, though. Neither platform makes it super easy to see exactly how much their spread markup is in real time. You get a quoted output amount, and you can compare that to the current market rate yourself if you want to do the math, but they don't just tell you "hey, our cut on this swap is $12.47." That lack of transparency is pretty standard in this corner of the industry, but it's still annoying.
KYC Policies: The "No KYC" Asterisk
This is the part where things get complicated, and where a lot of people get burned because they didn't read the fine print.
Both ChangeNOW and SimpleSwap market themselves as no-KYC services. And technically, that's true. For a normal, average, unremarkable swap, you don't need to create an account, upload ID, or prove anything about yourself. You just send crypto and receive crypto.
But.
Both platforms run AML (Anti-Money Laundering) screening on every single transaction. They use blockchain analytics tools to check whether the coins you're sending have any connection to sanctioned addresses, stolen funds, mixing services, gambling sites, or anything else their risk systems consider suspicious.
If their system flags your transaction? Everything stops. Your swap goes on hold. And then comes the email asking you to complete KYC verification, which typically means uploading a government-issued ID, sometimes proof of funds, and sometimes going through Sumsub's biometric liveness checks (basically, pointing your camera at your face while following on-screen instructions).
When Does KYC Get Triggered?
For ChangeNOW, the patterns reported by users and independent reviewers suggest KYC kicks in:
- On transactions above roughly €2,000 (this isn't an official number, but it's what people consistently report)
- When sending privacy coins like Monero
- When your coins trace back to flagged addresses
- When their automated system detects "suspicious patterns" (whatever that means)
For SimpleSwap, the triggers appear to be similar:
- Larger transactions (mid-four to low-five figure amounts seem to be the zone)
- Coins from mixing services or flagged sources
- Anything that trips their blockchain analytics providers
The frustrating part is neither platform publishes clear, specific thresholds. It's all "risk-based" and "case-by-case," which means you genuinely don't know if your particular swap will sail through in five minutes or get frozen for a week while you argue with support about your identity.
The Frozen Funds Problem
This is where the Reddit threads get really heated.
Both platforms have documented cases of users sending crypto, having the swap freeze, and then being told they need to provide KYC documentation before their funds will be released. For people who specifically chose these services to avoid KYC, this feels like a bait and switch.
ChangeNOW users report that when this happens, the resolution process usually works out eventually. You submit the documents, they verify, and the swap completes (or you get a refund minus network fees). Their support team is generally described as responsive and communicative, even when the situation is annoying.
SimpleSwap gets more mixed reviews in these scenarios. Multiple Reddit threads describe longer holds, vaguer explanations, and more "please wait" responses without concrete timelines. Some users have accused SimpleSwap of "holding coins hostage," though from a compliance perspective, the platform is doing the same thing ChangeNOW does. The difference seems to be more about how they communicate during the process.
Bottom line: if you're doing anything even slightly unusual, or if you're swapping larger amounts, be prepared for the possibility that either platform might ask for your ID. "No KYC" really means "no KYC most of the time, probably, unless our systems decide otherwise."
Supported Coins and Networks
Both platforms support a genuinely impressive number of cryptocurrencies, but the exact numbers depend on who you ask and what they're counting.
ChangeNOW claims support for over 1,500 cryptocurrencies with more than 2 million exchange pairs available through their API and broader liquidity network. On the actual retail website where regular users swap, comparison tools have counted around 607 coins available.
SimpleSwap goes even bigger on the headline numbers, claiming 2,800+ cryptocurrencies and 3.2 million+ trading pairs at the API/integration level. Their retail-facing site shows around 466 coins in some snapshots, though they've also advertised "more than 900 crypto and fiat currencies" elsewhere.
The discrepancy between "API-level" numbers and what you actually see on the website is real and kind of confusing. The API numbers include everything their liquidity aggregators can technically route, while the retail numbers reflect what's actively available to a regular user clicking through the interface on a given day.
For practical purposes, if you're swapping mainstream coins (Bitcoin, Ethereum, USDT, Solana, BNB, and similar top-100 assets), both platforms have you covered. For truly obscure altcoins, SimpleSwap might have a slight edge on total count, while ChangeNOW tends to have more coins readily available on its retail interface.
Both support major networks including Bitcoin, Ethereum, BNB Chain, Tron, Polygon, Solana, Avalanche, and many others. Cross-chain swaps are the whole point, so you can send BTC and receive ETH, or send SOL and receive USDT on Tron. Both handle this natively.
Speed and Reliability
On paper, both platforms promise "instant" swaps. In reality, "instant" means "as fast as the blockchain allows, plus a few minutes of processing." For most mainstream pairs, you're looking at 5 to 30 minutes from sending to receiving. Sometimes faster, sometimes slower.
ChangeNOW aggregates liquidity from both centralized exchanges and DEXes, which can sometimes help them find faster routes for your swap. Their transaction tracking is generally praised by users as clear and informative. You can see where your swap is in the process.
SimpleSwap also processes quickly for common pairs, but some users report more variability with less liquid trading pairs. If you're swapping something obscure, SimpleSwap might take a bit longer to find a route and complete the exchange.
Both have operated for years without any major platform-wide outages or security breaches, which counts for something. ChangeNOW's extra year of history (2017 vs 2018) gives them a slight edge in track record, but honestly, both are established enough that this isn't a meaningful differentiator at this point.
Security and Custody
Both services are non-custodial, which is genuinely important. They don't hold your funds in a persistent account. You send crypto, the swap happens, and the result goes straight to your wallet. There's no balance sitting on their servers waiting to be hacked.
ChangeNOW uses Sumsub for identity verification when KYC is triggered, which means they technically don't store your ID documents themselves (Sumsub does, as a GDPR-compliant third party). All data transmissions are encrypted, and they claim controlled, logged internal access. They cooperate with law enforcement in roughly 70 jurisdictions when valid legal requests come in.
SimpleSwap operates similarly: non-custodial design, third-party blockchain analytics for AML screening, and cooperation with authorities when legally required.
Neither platform has suffered a widely reported hack or security breach. The main "security" concern for users isn't someone stealing from the platform's hot wallet. It's the compliance-driven control over in-flight transactions. Your funds are safe from hackers, but they're not safe from the platform's own AML system deciding to pause your swap.
UX and Customer Support
The Interface
Both services keep things pretty simple. You don't need a manual to figure out how to use either one. Pick your input coin, pick your output coin, enter your wallet address, and go. ChangeNOW has a slightly more polished interface with better status tracking during the swap process. SimpleSwap earns its name by being... well, simple. Almost minimalist.
Neither is going to win any design awards, but they don't need to. The whole point is "get in, swap, get out."
Customer Support
This is where ChangeNOW has a clear advantage.
ChangeNOW offers 24/7 live chat directly on their site, and multiple review sources describe their support team as "top-notch" and responsive. Users consistently mention short response times, clear communication, and a willingness to help resolve even user-caused errors (like sending on the wrong network). Their Trustpilot profile is filled with positive support experiences.
SimpleSwap's support gets more mixed feedback. For straightforward questions, they're fine. Polite, reasonably fast. But when things go wrong (frozen swaps, AML holds, disputed refunds), the tone shifts. Users report more delays, more canned responses, and less concrete information about when their issue will be resolved.
If good customer support matters to you (and honestly, when you're moving money, it should), ChangeNOW is the safer bet between the two.
Privacy: How Much Do They Actually Know About You?
Both platforms collect more data than you might assume from a "no account needed" service.
ChangeNOW collects:
- Transaction details (currencies, amounts, wallet addresses)
- Technical data (IP address, device info, browser data)
- Optional email address if you use certain features
- Full identity documents through Sumsub if KYC is triggered
SimpleSwap collects:
- Similar transaction and operational data
- Technical logs and session information
- Identity documents when KYC verification is required
Both websites use standard web analytics (think Google Analytics or equivalent), cookies, and possibly marketing pixels. If you're accessing them from a regular browser, they know your IP, your device fingerprint, and your browsing behavior on their site. Neither claims to be a "zero-logs" service.
For everyday use from a clean wallet, both provide reasonable privacy compared to full KYC exchanges like Coinbase or Kraken. You don't need an account, you don't need to give your name for routine swaps, and the process is fairly anonymous in practice. But if you're a privacy maximalist who doesn't want any service to ever potentially connect your identity to a transaction? Neither of these is really built for that.
KYCnot, the privacy-focused review site, gives ChangeNOW a 5 out of 10 privacy score. Not great, not terrible. They flag the conditional KYC and the blockchain analytics as the main concerns.
ChangeNOW vs SimpleSwap vs CoinVast: Side by Side
So here's where I have to be honest about something. After spending all this time comparing these two, I kept thinking: there should be a better way. Both ChangeNOW and SimpleSwap have the same fundamental problem. They tell you "no KYC" and then maybe surprise you with KYC after you've already sent your money.
CoinVast takes a different approach, and I think it's worth putting all three side by side.
| Feature | ChangeNOW | SimpleSwap | CoinVast |
|---|---|---|---|
| Founded | 2017 | 2018 | 2024 |
| Effective Fee | ~0.7% (spread) | ~1.0% (spread) | Transparent, shown upfront |
| Fee Transparency | Spread baked into rate | Spread baked into rate | Fee displayed before you swap |
| KYC Policy | "No KYC" but can freeze and demand ID mid-swap | "No KYC" but can freeze and demand ID mid-swap | No account needed, pre-screening model |
| AML Approach | Post-deposit screening (freezes after you send) | Post-deposit screening (freezes after you send) | Pre-screening before you commit funds |
| Supported Coins | 600+ (retail), 1,500+ (API) | 460+ (retail), 2,800+ (API) | Growing selection of major coins |
| Account Required | No | No | No |
| Custody | Non-custodial | Non-custodial | Non-custodial |
| Support | 24/7 chat, highly rated | Chat support, mixed reviews | Responsive support |
| Trustpilot Rating | ~4.5/5 (10,000+ reviews) | ~4.5/5 (fewer reviews) | Building reputation |
The biggest difference, and honestly the one I think matters most, is the AML screening approach. ChangeNOW and SimpleSwap both screen your transaction after you've already sent your crypto. If there's a problem, your funds are already in limbo. You're stuck waiting, hoping, and potentially uploading your ID just to get your own money back.
CoinVast screens before you commit. The pre-screening model means you know whether a transaction will go through before you send anything. If there's an issue with the source of funds, you find out before your money is sitting in someone else's system. That's a fundamentally different experience, and it eliminates the worst scenario these swap services create: sending your crypto into a black hole and waiting days (or weeks) for resolution.
The fee transparency thing is also worth mentioning. With ChangeNOW and SimpleSwap, you get a quoted rate and you have to trust that the spread is fair. You can compare to market rate yourself, but they're not going to spell it out for you. CoinVast shows you the actual fee before you swap. You know exactly what you're paying. It's a small thing, but it matters when you're making decisions about where to exchange your money.
The Reddit Verdict
I spent a lot of time in the Reddit trenches for this comparison, and here's the general vibe:
ChangeNOW users who've never had a problem absolutely love it. Fast swaps, no issues, competitive rates. They'll recommend it to everyone. But the subset of users who've had transactions flagged tell a more complicated story, even though ChangeNOW support usually helps resolve things eventually.
SimpleSwap's Reddit presence is smaller. Positive experiences get mentioned but often feel less enthusiastic (more "it worked fine" than "it was great"). Negative experiences, particularly around frozen swaps and KYC demands, generate angrier threads with more accusations of scam-like behavior. Fair or not, that's the perception.
Both services have genuine fans and genuine critics. The ratio just skews slightly more positive for ChangeNOW.
Which One Should You Actually Use?
Look, I'll give you the honest answer based on everything I've found.
Choose ChangeNOW if:
- You want lower fees on average
- Customer support quality matters to you
- You're swapping common pairs and want a proven track record
- You value slightly better privacy positioning
Choose SimpleSwap if:
- You need access to a very specific obscure altcoin they support
- You're doing small, simple swaps where you want a dead simple interface
- You've used them before and had good experiences
Consider CoinVast if:
- You're tired of the "no KYC unless we change our mind" approach
- You want to know your swap will go through before you send your crypto
- Fee transparency matters to you
- You don't want to create an account but also don't want surprises
Here's my honest take. For the average person doing occasional crypto swaps, ChangeNOW is probably the better choice between the two established options. Lower fees, better support, and a longer track record. SimpleSwap isn't bad, but it doesn't really do anything better unless you specifically need a coin that ChangeNOW doesn't support.
But the pre-screening model that CoinVast uses? That addresses the actual problem with both services. The worst thing about instant swap platforms isn't the fees or the interface. It's sending your money and then finding out there's a problem. Any solution that eliminates that anxiety is worth serious consideration.
Frequently Asked Questions
Is ChangeNOW cheaper than SimpleSwap?
Yes, based on multiple independent comparisons from 2025 and 2026. ChangeNOW's effective total cost (including spread markup) averages around 0.7%, while SimpleSwap comes in closer to 1.0%. The difference varies by trading pair and market conditions, so it's always smart to compare the quoted output amounts on both platforms for your specific swap before committing.
Do ChangeNOW or SimpleSwap actually require KYC?
Not by default. Both allow you to swap without creating an account or uploading identification for routine transactions. However, both use AML screening on every transaction, and if their systems flag your swap as suspicious (large amounts, privacy coins, connections to risky addresses), they will freeze the transaction and require KYC verification before releasing your funds. This has happened to many users on both platforms.
Can ChangeNOW or SimpleSwap freeze my funds?
Yes. Both platforms can and do freeze in-flight transactions when their AML systems detect risk. ChangeNOW users have reported freezes on transactions above roughly €2,000, on privacy coin swaps, and on coins traced to flagged addresses. SimpleSwap has similar reports. In most cases, the situation is resolved through KYC completion or a refund (minus network fees), but the process can take days.
Which has more supported cryptocurrencies?
It depends on how you count. SimpleSwap claims 2,800+ coins at the API/integration level, more than ChangeNOW's 1,500+. But on the actual retail website, ChangeNOW has had more coins available in some snapshots (607 vs 466). For mainstream crypto, both cover everything you'd need.
Is there a better alternative to both?
CoinVast offers a different approach with pre-screening (checking for AML issues before you send your funds rather than after), transparent fees, and no account requirement. It's newer than both ChangeNOW and SimpleSwap but addresses the core frustration users have with both platforms: the risk of funds being frozen mid-swap.
Which is better for privacy?
Neither is truly anonymous. Both collect transaction data, IP addresses, and device information. Both use blockchain analytics and will share data with law enforcement on valid legal requests. ChangeNOW positions itself slightly more toward privacy-conscious users and scores marginally better on privacy review sites. But if maximum anonymity is your priority, both services have significant limitations due to their AML compliance practices.
