Skinvault is a relatively new CS2 skin trading platform from 2023. It was founded buy the Finnish team behind CSKeisari but is licensed in Dubai under the company Not So Boring FZCO (DSO-FZCO-43359).
The platform allows you to instantly trade or sell your skins via their automated bot system. Users may deposit and withdraw funds via VISA / Mastercard and several cryptocurrencies. They've got part-time support and seemingly low fees, although as with any B2C trading platform, they dictate the skin prices.
