John Brechisci Jr. is famous for creating the marketplace utilized by the skins trading industry, OPSkins Marketplace. As a player of the popular Steam-based game Team Fortress 2 and an active member of other video game community groups, Brechisci became aware of the constant scams that were plaguing item traders. Before OPSkins launched in 2015, users could only use proceeds from skin sales within the Steam gaming platform or risk scams through peer-to-peer trades.  Using his knowledge of the industry and the community, his passion for gaming, and his self-taught coding expertise, John set out to build a safe third-party platform where buyers and sellers could safely trade their items.
And thus, OPSkins.com was created to enable safe trading of Steam items for real-life money. More than 30,000 users signed up for the service on the first day.
Within months of its launch, OPSkins was clearing sizable revenue daily. It has grown substantially and today OPSkins is the largest centralized marketplace in the world to buy and sell virtual items in online games, trading for games includes Counter-Strike: Global Offensive, PLAYERUNKNOWN'S BATTLEGROUNDS, H1Z1, Dota 2, Team Fortress 2, Rust, Battalion 1944, and more. 
OPSkins transacts more than 2 million items each week and has processed more than 150 million transactions to date. 
In addition to being the Chief Technology Officer of OPSkins.com, Brechisci is now the lead designer of the Worldwide Asset eXchange™ (WAX), which will enable fast, safe, low-cost virtual item trades on its decentralized platform. Built on blockchain technology, WAX will allow anyone to create a fully functioning, decentralized marketplace that requires no investment in security infrastructure and payment processing. The result: enhanced price discovery, greater market liquidity, and a limitless global market for digital item trades. 
In June 2018, WAX ExpressTrade launched on OPSkins, a free, instant peer-to-peer trading service designed to make a difficult environment easier for digital item traders. WAX ExpressTrade achieved instant commercial success on a real world scale within just two weeks after launching, with the global adoption rate happening faster among item traders than the most successful product launch in the virtual item trading world up to now - OPSkins.
