Usually, each transaction gets done at its own unique exchange rate. Due to the volatile nature of the cryptocurrency market and the ever-changing network fees, the rate might change at any moment, and thus described as “floating”. As a result, you might get a different rate than you expected once your exchange is executed (completed).
Both Changilla website and Changilla mobile apps offer users a way to avoid exchange rate risk during the transaction interval. To lock the rate, (which Changilla refreshes every 30 seconds), click on the lock icon - that will activate the “fix rate” feature and guarantee the rate displayed on the screen. As soon as the transaction is created, a user has 15 minutes to send the money. Alternatively, users can exchange crypto-to-crypto at floating rates, for which Changilla charges the industry-wide lowest 0.25% fee.
Your email is required to create an account that grants you access to your transaction history, password editing and other account settings. Alternatively, you can create an account using an already-existing Facebook or Twitter.
A wallet is a digital place where you can store cryptocurrency coins and tokens. A wallet address is a randomly generated combination of digits and letters that is associated with a particular wallet. Changilla does not provide wallet addresses and never stores user deposits. To exchange cryptocurrencies on Changilla, you need to provide a previously-existing wallet address where you can receive your exchanged currency.
In any transaction there is always a sender and a recipient. The recipient’s address is the wallet address where you will receive the currency you buy. For example, if you want to buy Ether (ETH), you should specify an ETH wallet address in the recipient field, and Changilla will send coins to this address once the transaction is complete. In general, the recipient’s wallet address is a customer's address Changilla will send coins to once a transaction is complete.
Changilla 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 costs 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.
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.
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: Blockchain overload. There are many transactions waiting to go through, including yours. This issue occurs on the Bitcoin and Bitcoin-based blockchains. Unfortunately, the only thing to do is wait. Changilla has no control over a blockchain overload. Coin updates. We may turn off some coins to update a client. This can take some time. You will get your money as soon as we turn it back on. DDoS attacks. Every platform is subject to such attacks. Unfortunately, in this case the only thing to do is wait it out.
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.
Changilla’s trading algorithm is integrated into the largest cryptocurrency exchange platforms, including Binance, Poloniex, Bittrex, etc. In the span of milliseconds, Changilla makes bids and asks on the 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, which is why the exchange rate at the time of a transaction may differ slightly from the estimated rate that you see when you begin a transaction.
Exchange rate is the rate at which a unit of one currency can be exchanged for another. There are two exchange options available at Changilla web and mobile: floating and fixed. Each one is described below to help you choose one that suits you best.
Float could be beneficial when exchanging crypto-to-fiat on a rising market. Choosing floating rate makes sense if you are willing to accept the exchange rate uncertainty in favor of a low (0.25%) transaction fee.
Choosing the fixed rate makes sense when exchanging crypto while not willing to accept exchange rate market risk. This includes cases involving large amounts of crypto and/or periods of extreme market volatility.
2FA authentication is a method that keeps your account protected. To log in to your Changelly account, you’ll need to use a Google Authenticator app. You may turn the verification off anytime you want.
Just figure out what coin you want to buy and look for a stable compatible wallet. 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 you lose it. Changilla will never asks for your private keys. Store them in a safe place and never show them to anyone. If your private keys are stolen, your wallet and all your coins will be lost forever.
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 XRP). Whenever you make a payment in cryptocurrency, you receive a hash displayed in your wallet. 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.
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.
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.
Changilla supports most wallets. If your wallet address is recognized as invalid, it is usually for one of the following reasons: Make sure your wallet address matches the chosen cryptocurrency. You haven't updated or synced your BCH ABC wallet with a blockchain yet. There was a typo or character missing in the address you provided. Make sure that the address you specify matches the actual address of your wallet.
There are several reasons this might be happening: The transaction hasn't been included in a block. Cryptocurrencies aren't stable, so minor errors sometimes occur. If this happens we will either refund you your money or push the payment through if you can provide the hash (a tx ID) of your transaction. ETC and ETH confusion. The addresses of Ethereum (ETH) and Ethereum Classic (ETC) have the same structure. If you send ETC or ETH, make sure that you've selected the appropriate transaction type on Changilla. For example, if you create an ETH to BTC transaction, make sure that you send ETH, not ETC. Otherwise your transaction will get stuck. Wrong or missing XEM message. While sending XEM, make sure that you've put the correct message. It's indicated here and looks like a combination of digits and letters. Messages like 'Hey how are you’, or ‘I love Changilla' are lovely but won’t work, unfortunately. In case you indicated or forgot to put the valid destination tag for XRP or the valid memo for EOS/Stellar, the transaction won't be processed automatically and you'll have to contact our support team in order for your transaction to be either pushed or refunded manually.
A hard fork is a mandatory blockchain update that conflicts with the older version. In other words, you cannot use the currency anymore unless you haven’t upgraded the client. The reason of a hard fork can be fixes for a major bug or blockchain improvements. Hard forks should be supported by all members of the crypto community, otherwise it can lead to blockchain replication.
