Terms of service

CoinVast is an instant cryptocurrency exchange that runs at coinvast.io. We launched in 2026. You send us one cryptocurrency, we send you a different one, and that is the entire relationship. No accounts, no sign-up, no newsletter you never asked for.

There is no company name to print here yet, because the operating entity is still being formed. The moment it is registered, its legal name, registration number, and registered address will appear in this exact paragraph. Until then, the notice box above applies, and we would rather show you an honest blank than a made-up letterhead.

You can reach the people who run the service at [email protected]. A human reads that inbox. Not a ticket robot that asks you to rate its empathy, an actual person who can look up your order and tell you what is going on.

These terms are an agreement between you and us. By creating an order you accept them, the same way you accept a parking garage’s rules by driving in. If you do not agree with something here, the right move is simple: do not create an order. Nothing on this site requires registering, so walking away costs you exactly nothing.

The service does one thing. You pick a pair from the thirty-plus coins we support, we quote you a rate, you send the deposit, and we send the payout to an address you control. Every swap is a single, self-contained transaction with its own order page and its own link. There is no premium tier, no loyalty program, and no password to forget, because there is no account to attach any of that to.

Just as useful is the list of things we are not, because crypto services love to blur these lines.

• We are not a wallet. Do not park funds with us. We hold your coins only for the minutes it takes to screen and execute a swap, and the whole system is built around getting them out the door, not keeping them warm.
• We are not a custodian or a bank. Nothing here is insured, deposit-protected, or interest-bearing. If you want a savings product, you are in the wrong tab.
• We are not a fiat service. No euros, no dollars, no cards, no bank transfers. Coins in, coins out.
• We are not a broker or an advisor. Nothing on this site is investment, financial, tax, or legal advice. If we say a coin is popular, that is a remark about our order flow, not a tip.
• We are not a mixer or an anonymity tool. Every swap is an ordinary exchange transaction with a record, and the privacy policy describes that record honestly.

Here is the whole agreement, compressed. You pick a pair and get a quote that shows the rate, our spread, and the network fee before you commit to anything. You send one payment to the deposit address within 30 minutes. We screen before the swap completes, not after: the deposit — the coins you send and the address they come from — is screened against risk and sanctions data before the exchange leg begins, so a deposit either proceeds or goes back to you minus the network fee, with one narrow exception for sanctions law described in section 9. Once your payout confirms on its blockchain, the swap is complete and final, in both directions: we cannot claw it back from you, and you cannot undo it. You are responsible for the addresses you type. We are responsible for everything between your deposit confirming and your payout landing. If the rest of this page said only that, in a larger font, it would still be a fair summary.

To use CoinVast you must be at least 18 years old (or older, if the age of majority where you live is higher), legally able to enter a contract, and allowed by your local law to use a cryptocurrency exchange like this one. We do not run identity checks on normal swaps, which means we cannot verify any of this for you. So the responsibility sits where it honestly has to sit: with you.

You promise three things every time you create an order. First, the coins you send are yours to send: lawfully obtained and lawfully controlled. Second, you are acting for yourself, not for someone who would fail the next sentence. Third, you are not a sanctioned person, you are not acting on behalf of one, and you are not located in a territory under comprehensive sanctions.

We do not check passports, but we do check the coins. The deposit, and the address it came from, are screened against risk and sanctions data before the exchange leg begins, and a sanctions hit means the swap never completes — the deposit returns to you, except where sanctions law forbids it. That distinction matters: we screen the coins, not the human. It is what lets normal people swap without paperwork while still keeping sanctioned funds out of the pipes.

If anything in this section is untrue for you, do not use the service. There is no exit fee for closing this tab.

An order moves through a handful of states, and the order page always shows the current one in plain words. Here is the whole journey, narrated like a person instead of a state machine.

The quote. You pick a pair and an amount, and the card shows the rate, the spread inside it, the network fee, and exactly what you will receive. A quote stays valid for about 60 seconds, because crypto prices move constantly and an old quote is a wrong quote. Creating an order from a live quote locks that quote’s terms, rate and all, to your order.

Awaiting deposit. You now have 30 minutes to send one payment of the quoted amount to the deposit address we show you. One payment, the exact amount, on the right network. If your coin needs a memo or destination tag (XRP and Cosmos, we are looking at you), include it. After 30 minutes with no deposit, the order expires. Nothing bad happens when an order expires; you were never charged anything. Just do not send coins to an expired order. If a deposit does arrive late, it is not lost: it goes to a human for review and is returned minus the network fee, but that path is slower and duller than simply creating a fresh order.

Confirming. We saw your transaction and are waiting for the network to bury it under enough blocks. Each coin has its own count: 2 confirmations for Bitcoin, 4 for Litecoin, 12 for Ethereum, 30 for Dogecoin. Kaspa wants 100, which sounds dramatic until you learn its blocks arrive about once a second. Your deposit is screened during this stage, before anything is exchanged, which is the entire point of how we work.

Exchanging. The deposit is confirmed and screened. We convert it at your order’s terms. This is usually the shortest step.

Sending. The payout is broadcast to your address, and its transaction hash appears on the order page so you can watch it land on any block explorer you like.

Completed. Your payout has confirmed on-chain. The swap is final. Keep your order link; it is your receipt and the only key to that order. The site keeps a convenience list called My swaps, but that list lives in your own browser, not on our servers, so the link is the thing to actually save.

Our pricing has two parts and zero footnotes. The spread is our margin: a flat 2%, the same on every swap, locked the moment you create the order. The network fee is what it costs to send your payout on its blockchain, charged at cost and printed as its own line on every quote. That is the complete list. No deposit fee, no service fee, no withdrawal fee, no fee with a mysterious name that appears at the last step.

Percentages are slippery, so let us walk through one swap with actual numbers. Say you send 1 LTC and want BTC. Pretend Litecoin trades at $90 and Bitcoin at $100,000; round numbers so you can check the math in your head, since live prices obviously move. The mid-market rate is 90 divided by 100,000, so 1 LTC equals 0.00090000 BTC. Our 2% spread comes off that rate, which makes your quoted rate 0.00088200 BTC. Then the Bitcoin network fee, say 0.00005000 BTC, is shown on its own line and subtracted. The card reads: you receive 0.00083200 BTC. And that is what arrives, locked from the moment you created the order, no matter how long the deposit takes to confirm.

Two honest notes. The mid-market price we quote against comes from public market data, and the spread is applied to it in the open; we do not pad the rate and then advertise “0% fees”, a trick we find genuinely embarrassing for this industry. And the network fee is an estimate of the chain’s real cost at payout time, not a quiet second margin. When fees on a chain spike, that line goes up, and when they fall, it comes down.

Every order locks its rate the moment you create it. There is one pricing model here, not a menu: a flat 2% spread over the mid-market rate, fixed at quote time. Whatever the market does while your deposit confirms is our problem, not yours. The rate you saw on the card is the rate that settles your swap, however long the next half hour turns out to be. We do not keep the upside when the market moves our way and refund the downside when it moves yours; the locked rate cuts both directions out of the deal entirely.

Now the awkward cases, because exact amounts and human beings only sometimes coincide. Small differences, up to about half a percent either way, are simply absorbed and the swap proceeds as quoted. Beyond that, two rules apply, and they come straight from how the system actually behaves.

If you send less than the quoted amount, we will not pay the full quote against a short deposit, for reasons you would find reasonable if you ran an exchange. The order holds at the confirming stage and a human operator reviews it. The outcome is one of two things: the swap settles on the amount you actually sent, or the deposit is refunded under section 8. Your coins are never silently kept, and the order page never just goes dark.

If you send more than the quoted amount, the payout reprices on the full amount you actually sent, at the rate locked when you created the order, so the extra automatically buys proportionally more — there is nothing to refund and nothing to claim. The locked rate protects you; the larger deposit simply earns a larger payout.

When a swap cannot complete, your deposit comes back. The amount returned is your deposit minus the network fee for the return transaction, because moving coins on a blockchain costs money in both directions and we do not eat fees for swaps that never happened. We add no penalty, no processing charge, no restocking fee. Just the chain’s own toll, the same one you paid to send the coins in the first place.

Where the refund goes is the part you control. Every order asks for an optional refund address, and we nag about it because it is the guaranteed return path. With one on file, refunds are automatic and boring, which is exactly what you want a refund to be. Without one, things get harder: on some chains we can derive the sending address and return funds there, but on others we cannot, and returning coins to an exchange’s shared deposit address can strand them in that exchange’s internal limbo. Thirty seconds pasting a refund address spares everyone that adventure.

So when do refunds actually happen? When a deposit fails screening: back it goes, minus the network fee, with the return transaction hash printed on your order page. When an underpaid or late deposit is reviewed and refunding is the right outcome. And when a swap fails for reasons on our side, like a paused pair or an operational fault: same policy, your coins return, no questions asked of you because you did nothing wrong.

What is never refundable: a completed swap. Once your payout confirms on-chain, the trade is done in both directions. Blockchains do not have an undo button, and we cannot build one on top of them. If you swapped the wrong coin or mistyped an amount and the swap completed, the result is yours. We say this bluntly here so it never has to be said sadly later.

Every swap is screened before it starts. When you create an order, the deposit and payout addresses are checked against blockchain risk data and sanctions lists, before you send anything. If an address fails that check, the swap simply never begins: no deposit, no limbo, nothing to chase. The deposit itself is screened again once it appears on-chain and before the exchange leg runs. Nothing is ever exchanged unscreened, which is why nothing ever needs to be frozen after the fact.

Screening sounds dramatic, so let us deflate it. It is an automated lookup against published risk and sanctions data. We are a swap service, not a detective agency. Nobody here reads your transaction history over coffee, and nobody wants to. The check exists to keep stolen funds, ransomware proceeds, and sanctioned money out of the same pipes that you, a normal person with normal coins, are standing in.

If a deposit fails screening after it arrives, the policy from section 8 applies automatically: the coins are returned to your refund address minus the network fee, the order shows the rejection in plain words, and the return hash sits right there on the page. We do not demand documents to “release” anything, because there is nothing being held to release.

And now the exception, stated as plainly as we can manage. If an address is on a sanctions list, the law can forbid us from sending the funds back at all, because returning sanctioned money is itself unlawful in the places that matter to us. Sanctions hits are therefore the one case where coins can be held under a legal hold instead of auto-returned. It is the single exception to the return policy, it is narrow, and we would rather print it here in full view than have anyone discover it as a footnote. Everything that is not sanctions gets the boring outcome: returned, minus the network fee.

Most of this list is obvious, but contracts like lists, so here it is. You must not use the service for any of the following:

• Laundering money, financing terrorism, or moving the proceeds of crime, including ransomware payments, stolen coins, and darknet market settlements.
• Evading sanctions, or swapping on behalf of a sanctioned person, entity, or territory.
• Defrauding anyone, including using us as the cash-out step of a scam played on somebody else.
• Attacking the service itself: probing for holes, scraping at abusive rates, spamming orders, or hammering the API in ways designed to break or distort it.
• Using the service anywhere your local law forbids it, or while misrepresenting any of the promises in section 4.

One warning we give from observation rather than caution. If a stranger from the internet, a “trading platform” that found you on a chat app, or a brand-new online romance is instructing you to swap coins and send them somewhere, stop. That script ends with your money gone, and because completed swaps are final, nobody can bring it back. Not us, not the police hotline, not the nice person who promised to double it. We would honestly rather lose your order than process your scam.

We may refuse, reject, or unwind (by refund) any order at our discretion, including when screening results, fraud signals, or plain common sense require it. Refusal looks like the refund policy in section 8. It never looks like your funds quietly disappearing.

This is the section where companies traditionally switch to Latin. We will keep it in English.

If we are liable to you for something connected to an order, our total liability is capped at the value of that order’s deposit at the time we received it. Not your hoped-for gains, not what the coin was worth the following Tuesday, not your time spent refreshing the order page. The deposit’s value, once. That cap is honest about the economics of a service that charges a 2% spread: we can stand behind every deposit, and we cannot underwrite every dream attached to one.

And here is what we are not liable for, because we genuinely cannot control it. Addresses you typed or pasted wrong: a payout to a wrong but valid address is irreversible by the nature of blockchains, not by our preference. Deposits sent on the wrong network, in the wrong asset, or without a required memo or tag. Lost order links. Blockchain failures of every flavor: congestion, reorgs, halted chains, absurd fee spikes. Outages of third parties we rely on, like market data feeds, screening data, and node providers. And indirect or consequential losses of any kind, which is the legal term for the damage caused by the damage.

The service is provided as is and as available, without warranties of any kind. We work hard to keep it fast, accurate, and online, and section 12 explains how we behave when it is not, but effort is not a warranty and we will not dress it up as one. None of this section limits liability that the law refuses to let anyone limit, such as liability for fraud, and where consumer law gives you rights these terms cannot take away, those rights win.

Pairs come and go. A coin can be paused because our float for it ran low, because its chain is having a bad day, or because a provider we depend on fell over. When that happens we would rather show you an honest error than a quote we cannot honor, so a paused pair simply stops quoting until it is healthy again.

Orders already in flight are never abandoned to a pause. An in-flight order either completes under its own terms or ends in a refund under section 8. Those are the only two exits, and both of them end with coins in an address you control.

We may also change the service itself: add coins, remove coins, adjust limits, redesign pages, or take everything down briefly for maintenance. We do not promise uninterrupted availability, and any service that does is being creative with either its uptime or its honesty. What we do promise is that downtime never changes the rules for money already in motion. Your deposit follows the steps in section 5 wherever it can, and the refund policy wherever it cannot.

If something looks wrong with your order, write to [email protected] and include the order ID from your order link. That ID lets us see exactly what you see, plus the machine’s view of it, which is usually where the answer lives. A human reads the inbox and a human answers it. Response times vary with how on fire things are, but the inbox is not decorative.

We ask one thing: give us a real chance to fix a problem before escalating it anywhere else. The overwhelming majority of disputes turn out to be a slow chain, a missing memo, or an underpaid deposit waiting for review, and every one of those resolves faster by email than by anything involving letterhead.

If we truly cannot resolve a dispute between us, the formal route (which courts, which law, which country’s idea of a stamp) will be defined by section 14 once the operating entity exists. Until then, email is both the informal and the formal channel, which at least keeps everyone’s postage costs down.

Governing law and venue will be stated here once the operating entity is registered, and until that day this section deliberately says nothing else, because a placeholder pretending to be a jurisdiction would help nobody.

We will change these terms over time, because the service will grow and because counsel, when they arrive, will have opinions. Two commitments make that safe for you. First, the version of these terms published at the moment you create an order is the version that governs that order; we cannot rewrite the rules for coins already in motion, and we would not want to. Second, every change lands on this page with the date at the top refreshed, and material changes get called out plainly rather than slipped in between commas. If you read a version you liked and want to keep it, your browser has a print button and we have no objection.
