We are sorry to announce that we need a few days to implement some crucial changes to the website. ETA June 18th.
In the meantime, you can use our main trading platform which supports trading between multiple games: swap.gg
csgoswap.com and h1z1swap.com will redirect to swap.gg in the future, swap.gg is operated by us too. We are currently working on the release of the new version of swap.gg.
In the new version of swap.gg, we carry out new techniques to make sure there are enough skins to choice from.
User balances will be transferred to swap.gg. The new version will be released very soon.
