The main thing here: it depends on an exchange. We will consider listing on one of the main exchanges – Bittrex as the process of listing there was well described on coinist.io.
“Submitting a request on Bittrex requires all of the following info:
– Your coin name: self-explanatory.
– Enhanced Verified Account: a team member or shareholder holding more than 10% of the company, must have their identity verified on Bittrex. As with Poloniex, this saves the team time vetting.
– Description of your coin: What makes your currency different than the hundreds of others floating around? The Bittrex website warns “If your ANN thread only has coin specs on it, you are not going to get listed on Bittrex.” Have a clear mission and pitch.
– Coin Trading symbol: a 3-5 letter ticker that will represent your coin forever. No numbers allowed.
– A coin logo: Must be submitted in PNG format with a transparent background. Bitcoin’s orange tilted B is ubiquitous worldwide. You should have a slick-looking logo.
-A launch date: if your coin will or already ran an ICO
-Github link: Bittrex requires the source code for their due diligence. They will not accept binary.
Additional questions required are: the max money supply, other exchanges you’re listed on, the official blockchain explorer, the TxFee, the results of a premine (if there was one), how money was raised, and links to your company’s social media.
ETH tokens require a few additional notes. If you’re launching a token through Ethereum and had the code on your smart contract reviewed, Bittrex wants to see those results, as well as your smart contract address.
In addition to all that required info, Bittrex recommends publicly disclosing your identity and having your coin source code checked by a trusted community member. If you launched the coin via ICO, Bittrex needs details about that as well. The premine info, how much was raised, the publicly accessible information at launch time, and so on. This all matters; Bittrex warns that a $5000 compliance fee may be charged if enough due diligence is necessary.”
