Changelly is an instant cryptocurrency exchange providing the best crypto-to-crypto rates on the market.
Changelly’s robot is integrated into the largest cryptocurrency trading platforms, including Poloniex and Bittrex. In the span of milliseconds, the robot makes bids and asks on the trading platforms, then selects and suggests the best available rate and displays the estimated rate on our site. The rates remain approximate until the transaction is actually made on the blockchain. The exchange rate at the time of a transaction may differ slightly from the estimated rate that you see when you begin a transaction. To learn more about the process, see this article.
Changelly is a young and promising project created by MinerGate enthusiasts. The service provides safe and fast transactions without revealing users identities. We provide the best possible rates by comparing a wide range of reliable trading platforms and work in over 50 cryptocurrencies listed.
Further reasons to trust Changelly:
We don’t fix currency rates and never have because of the volatile nature of cryptocurrency, where the rate of any currency can fluctuate every minute. This is why the final rate may be slightly higher or lower than expected at the end of a transaction.
Keeping the rates fixed would require us to cover market risks and currency volatility, which as a result would make our commission fee much higher. Instead, Changelly charges a quite low commission fee (0.5%) and offers the best available rate at the moment the transaction is completed.
Your email is needed to create an account that gives you access to your transaction history, password editing and other account settings. Alternatively, you can create an account one of the social media platforms listed.
2FA authentication is a method for keeping your account protected. To log in to your Changelly account, you’ll need a second device with Google Authenticator installed.
You may turn the verification off anytime you want.
There is no option to delete an account on Changelly, so you may return anytime you want.
A wallet is a digital place where you store cryptocurrency coins and tokens. A wallet address is a randomly generated combination of digits and letters that is associated with a particular wallet.
Changelly does not provide wallet addresses and never stores user deposits. To exchange cryptocurrencies on Changelly, you need to provide a wallet address where you can receive your exchanged currency.
Just figure out, what coin do you want to buy and seek for a stable wallet version. As a rule, each coin has its official wallet client.
Note that each wallet has its unique address or a tag with a private key that is required to restore your wallet if lost. Changelly never asks your private keys. Store them in a safe place and never show anyone. Once private keys are stolen, you wallet with all the coins will be lost forever.
There is always a sender and a recipient. The recipient’s address is the wallet address that will receive currency you want buy. For example, if you want to buy Ether (ETH), you should specify an ETH wallet address in the recipient field.
In general, the recipient’s wallet address is a customer's address Changelly will send coins to once a transaction is complete.
A hash (or tx ID) is the unique address of a transaction in a blockchain that acts as a record or proof that the transaction has taken place. Usually, the hash is a combination of digits and lowercase letters (uppercase in the case of Ripple). Whenever you make a payment in cryptocurrency, you receive a hash displayed in your wallet. It looks like this:
Every hash should be located in a blockchain. If you have any issues with a transaction on our platform, our support team may ask you to provide the hash for the transaction in order to find your payment and resolve the issue.
The buying process is the same for all coins available on Changelly:
Changelly doesn’t have set amount restrictions. However, there are some cases when a minimum amount applies:
If an amount is very low, make sure that it will cover all network fees network fees required by a blockchain. This means that the amount you are going to send and the amount you are going to receive should be enough to cover input and output network fees taken by a blockchain.
If your funds to be exchanged are insufficient, you will see a message like this.
Please follow the amount recommendations we provide. Otherwise, there is a high risk that your transaction will go through and your money will be lost.
For large amounts, there are no restrictions at all, you’re free to exchange as large a sum as you want. Note that in this case the time of transaction processing will depend on the capacity of the blockchain and the amount of network fees set by your wallet.
Tip: in order to prevent market pump/dump, divide a large amount into smaller ones and wait for a couple of hours between sending them. In this case you will not create an overwhelming ask for a currency you want to buy, so that its final rate will be much profitable.
Each time any amount of cryptocurrency is sent or exchanged, the currency goes through a blockchain. This process requires a small fee called a ‘network fee’. The network fee is a commission that a blockchain takes from the amount sent in each currency. It is critical to make sure that the amount you want to exchange on Changelly is enough to cover the exchange fees for both the process of sending your original currency and receiving the new currency you want to buy. If the sent amount is too low to cover the fees of the network, the transaction will not go through and your funds will be lost.

Unfortunately, blockchain transactions are irreversible. Once a transaction is made (money is sent to a particular wallet address), it cannot be rolled back. So, if you are going to exchange cryptocurrency, be sure to double check all payment details carefully before sending.
All transactions take time to be processed (usually 5-30 minutes). Given the volatility of cryptocurrencies, the exchange rate is subject to change during the processing time, which means the final rate may be slightly different from what you expected. This happens because Changelly doesn’t fix currency rates.
Changelly transactions take 5-30 minutes to be processed. If a transaction is large (worth over 1 BTC), processing may take longer, depending on the size of your transaction and blockchain capacity.
Changelly supports most wallets. If your wallet address is recognized as invalid, it is usually for one of the following reasons:
As a rule our transactions take 5-30 minutes to be processed. It your transaction takes longer, this could be due to a variety of factors, including:
There are several reasons this might be happening:
In the DASH, DOGE or other Bitcoin based blockchains, you may see the status of your transaction as ‘Not yet redeemed’. It means that your transaction is complete, but it hasn't been used as input for another transaction. In other words, your coins are received, but you haven’t spent it yet. You need to update and sync your wallet in order to see the coins reflected in your wallet.
All wallet addresses (including memos, destination tags and messages) provided by Changelly are reusable and tied with your recipient address. You can send another amount of coins to the address generated before multiple times without creating a new transaction on Changelly.
Hard fork is a mandatory blockchain update conflicting with the older version. In other words, you cannot use the currency anymore unless you haven’t upgraded the client. The reason of hard fork can be major bug fixing or blockchain improvements. Hard fork should be supported by all members of the crypto community, otherwise it can lead to blockchain replication.
A memo is a combination of digits and letters required to assign STEEM to a certain Steem wallet user. Memos are used in Steem wallets and indicated right here.
In wallet, a memo should look like this
If you want to buy Steems, make sure that you've specified a correct memo while putting in a wallet address.
Note that if you also have a nickname on steemit.com, you can use as your wallet address and that doesn't require a memo.
A destination tag is a short complementary combination of characters required for certain Ripple wallets. When buying Ripple, make sure that you have specified a destination tag, if required. Likewise, when you send Ripple to us, do not forget to include the destination tag, provided near the address you should send to.
A message is an additional tag required for XEM transactions. Whenever you send or receive XEM, make sure that you input a message. You can find the message in your wallet, it should look like this:
