Blockchain development related Services/Portfolios
For nearly 2 years, we worked together with a company offering an online trading platform for virtual gaming goods and developed a cryptocurrency, which provides tokens that allow virtual goods to easily be tokenized and exchanged for cryptocurrency. This cryptocurrency was built from scratch based on EOS and was placed in the top 5 of cryptocurrencies with the most daily transactions.

We also currently work with one of the largest worldwide Bitcoin peer-to-peer marketplaces, based in New York.
