Short answer: app.changerella.com asks about a dozen instant exchanges for the same swap at the same moment and shows what each of them would really pay out — sorted by rate, by speed or by KYC risk. You pick an offer, send the deposit straight to that exchange, and the coins arrive at your own address. No account, no funds held by us, roughly 250 coin-and-network combinations.
What Changerella App is
Changerella App is a non-custodial aggregator of instant crypto exchanges. It is not an exchange itself and it never touches your money: it queries the services it is connected to, ranks their offers, and hands you the deposit address of the one you chose. From that point the swap is between you and that provider.
The monitoring side of Changerella has always answered the question which service is worth using. The app answers the narrower and more expensive question: for this exact pair, this exact amount, right now — who pays out the most? Those two questions have different answers more often than people expect, because rates on the same pair drift apart minute by minute.
Why one quote is never enough
Every instant exchange builds its own price out of the same three ingredients: the market rate it reads, the spread it keeps, and the network fee it expects to pay on the payout. Each of them is a business decision, so on any given pair the offers spread out. The gap between the best and the worst payout on the same pair is routinely larger than the network fee people spend an hour optimising.
Checking that by hand means opening ten tabs, entering the same amount ten times, and finishing after the quotes you started with have already expired. The app does that fan-out in parallel and shows the offers as they land, so the comparison is of quotes taken at the same moment rather than over ten minutes of drifting.
How a swap works, step by step
- Pick the pair and the amount. The picker only lists coins that at least one connected exchange will actually swap in that direction — not everything the providers happen to have in their catalogues.
- Choose fixed or floating. Fixed locks the rate for a window; floating settles at whatever the market gives when your deposit lands.
- Read the offers. Each row is one exchange with its payout, its expected time and its KYC rating. Sort by whichever of the three you care about.
- Enter your addresses. The recipient address is checked against the network you selected. The refund address is optional but worth filling in — it is where the provider sends the money back if the swap cannot complete.
- Send the deposit and watch the status. The deposit goes to the exchange you picked, never to us. The order stays in your browser, and it also has an ID you can paste on any other device to find it again.
What the offer list actually tells you
| Column | What it means |
|---|---|
| Exchange | The service that will hold and process the swap. Its name, its terms, its support. |
| You receive | The payout the provider quoted for your amount, after its spread and payout fee — not a mid-market rate with the costs left out. |
| Time | The median completion time of that provider's last hundred finished orders, counted from the moment the deposit was seen — not from when the order was created. |
| KYC risk | A to D: A means no verification expected, D means verification is likely. It is a rating of the provider's behaviour, not a promise. |
Two details behind that table matter more than they look. The time column is a median rather than an average, so a single order that hung for two days does not poison the estimate. And offers whose amount falls outside a provider's own minimum or maximum are dropped before you ever see them — choosing such an offer would fail at the last step, after you had already committed to it.
Fixed or floating
| Fixed rate | Floating rate | |
|---|---|---|
| What you are promised | The exact amount shown, if the deposit arrives in time | Whatever the rate is when the deposit is credited |
| Cost | A wider spread — the provider is carrying the risk | Usually the better headline number |
| Sensible for | Large amounts, volatile pairs, slow networks | Small amounts, stable pairs, fast networks |
The toggle sits above the amount field, and switching it re-runs the whole comparison — a provider that wins on floating is not necessarily the one that wins on fixed. The trade-off is unpacked in detail in fixed vs floating rate crypto swaps.
What it deliberately does not do
- It does not hold your coins. There is no balance, no wallet, no withdrawal queue. The deposit address belongs to the provider you selected.
- It does not ask you to register. No email, no password, no account to lose. Your order history lives in your own browser, and an order ID retrieves an exchange anywhere else.
- It does not perform KYC — and cannot promise the provider will not. Verification is the provider's decision, usually triggered by their own risk scoring. The A–D rating tells you how often that tends to happen there; it is guidance, not a guarantee. If avoiding it altogether is the goal, start with the privacy guide.
- It does not invent rates. Every number comes from the provider that would honour it, and it changes as fast as they change it.
It installs like an app
Changerella App is a web app you can install: on Android the browser offers it directly, on iPhone it is Share → Add to Home Screen. There is nothing to download from a store and nothing to grant permissions to. Installed, it opens full screen without an address bar, and the last rates and your order list stay readable with no network. The interface is available in English and Russian.
How it fits with changerella.com
The two halves answer different questions and link into each other where that helps. On the monitoring site, crypto-to-crypto pages show a card offering to swap on the spot — but only when the aggregator genuinely covers that pair, and the link carries the pair with you so you do not re-enter it. Going the other way, when what you want is a reviewed service, a cash office or a specific direction, the exchangers list is still the right tool.
If the concept is new to you, what a crypto exchange aggregator is covers the mechanics, and aggregator vs single exchanger covers when each one is the better choice. Before sending anything anywhere, the ten-point vetting checklist is ten minutes well spent.
FAQ
Do I need an account to use Changerella App?
No. There is no registration, no email and no password. Orders are stored in your browser, and each one has an ID you can use to find it from another device or browser.
Does Changerella hold my crypto during the swap?
No. The app is non-custodial: your deposit goes directly to the exchange you selected, and that provider sends the payout to your address. Changerella never receives or holds the funds.
How many exchanges and coins does it cover?
About a dozen instant exchanges are connected, covering roughly 250 coin-and-network combinations — close to a hundred coins across dozens of networks. A coin only appears in the picker if at least one connected exchange will really swap it in that direction.
Will I have to pass KYC?
That is the provider's decision, not ours. Each offer carries an A-to-D KYC rating showing how likely verification is with that service, so you can sort by it, but no aggregator can promise a provider will never ask.
Why do the offers differ so much for the same pair?
Every exchange sets its own spread and prices in its own payout network fee on top of the market rate. Those are independent business decisions, so the payouts spread out — which is exactly why comparing them at the same instant is worth doing.
What happens if a swap cannot be completed?
The provider returns the funds to the refund address you entered when creating the order. That field is optional, but leaving it empty means recovery depends on contacting the provider's support instead.
Is Changerella App free?
Yes, for you. There is no fee on top of the provider's own rate; the project earns from the exchanges' partner programmes, and the payout you see in the list is the payout you get.
