# Purchasing a domain

Before launching the exchange service and purchasing a license, it is important to determine a unique domain name in advance, as this factor directly affects the possibility of being listed in monitoring services later.

When reviewing applications, BestChange separately checks the project name: the domain must not match or be similar in spelling or sound to existing exchange services or well-known brands. Even partial matches can be grounds for rejection.

A unique domain creates an independent brand, reduces the risk of application rejection, and helps avoid legal and reputational problems. It is recommended to check the chosen name in advance through search engines and Whois services, rule out any variations of well-known projects, and prefer simple, readable, and memorable names.

After purchase, you will need to change the DNS records to Cloudflare's records so that all traffic goes through it first and only then reaches your site. This makes it possible to filter malicious traffic and configure protection against DDoS attacks. Cloudflare also provides free SSL certificates, thanks to which your site will open over the secure https\:// protocol.
