No. StellarX doesn’t promote anyone’s token under any conditions. StellarX doesn't vet or vouch for any of the tokens on the Stellar network, and if you write us asking us to help you promote your token, we're a lot more likely to make fun of your project than anything else. Everything else you see on the site is done programmatically; there is no "editorial" or "curatorial" control other than the standards we've discussed here.
The more you adhere to Stellar’s issuance guidelines, the more exposure you’ll get on StellarX. For instance, when users choose to filter the markets view based on asset type, we’ll only show tokens that have a complete stellar.toml file.
To find out how to take the vital step of completing your stellar.toml, follow this guide.
