We needed help listing cryptocurrencies on centralized exchanges. Tried both ourselves and through different companies, but overpriced and uncertain. implemented in Polygant without much hope! After the first contact, we received an adequate offer for the cost and time of listing on 3 exchanges from the top 20 CoinmarketCap. They did everything clearly on time, helped with the preparation of legal documents, the conclusion of the process of contracts with exchanges and controlled all the technical input of our coin documentation to the exchange. We recommend their listing services on cryptocurrency exchanges.
