ChangeNOW is a non-custodial crypto-to-crypto exchange where you can trade a large number of coins quickly, conveniently, registration-free, and without any limits. Although it normally does not require KYC it could be that one of your transactions is marked as suspicious and then they will require you a KYC procedure.

KYC-Related Terms of Service

The crypto market is subject to a number of certain rules and regulations which make it mandatory for most crypto services to have the AML/KYC procedure implemented.

ChangeNOW strives to protect our clients from any type of scams and fraudulent activities in the crypto world and complies to all rules and regulations present at the moment, and one of the ways that enables us to do so is the KYC/AML procedure.

ChangeNOW’s AML/KYC procedure is supported by an automated risk prevention system. If a transaction is marked suspicious by this system, the exchange is put on hold and the customer in question is then asked to confirm their identity.

We do everything in our power to maintain our reputation as a legitimate, law-abiding exchange service that can be safe for use by anyone, be it a regular person who doesn’t deal with crypto much or an experienced trader or miner; therefore, ChangeNOW reserves the right to apply the KYC/AML procedure to certain clients, wallet addresses and select assets.

In case a client doesn’t wish to disclose their identity for certain reasons and refuses to provide the documents, the KYC/AML procedure is considered failed and the deposited funds are then refunded to the address (or addresses) the deposit was made from, subtracting the network fees, within 24 hours. Then, ChangeNOW reserves the right to blacklist this address (or addresses), thus rendering it (or them) non-eligible for making deposits on the service.
