Cratex is an international spot cryptocurrency exchange that has been operating since 2018 from the domain cratex.io. The platform positions itself as a marketplace for smaller and emerging digital assets, listing cryptocurrencies and trading pairs that often have limited availability on the major centralized exchanges. It is built for retail traders who want access to a wide selection of altcoins at a single, predictable fee rate. Cratex does not disclose its country of incorporation and describes itself as an international trading environment open to users worldwide.

The fee structure is straightforward: a flat 0.10% trading fee applies to every transaction, with no distinction between maker and taker, and per-asset withdrawal fees are published on the assets and fees page. Cratex offers a publicly accessible REST API that lets developers and data consumers retrieve live market information, including buy and sell prices, order book data, and aggregate statistics for every listed trading pair. The API is versioned (currently v1) and does not require authentication for market data endpoints, which makes it useful for hobbyist scripts and lightweight portfolio tools.

The exchange lists trading pairs across dozens of cryptocurrencies, with a particular emphasis on smaller-cap and niche assets, and runs a native token called Cratex Token (CRATX) that ties into account features within the platform. Customer support runs through a Discord server and a dedicated support portal on the website. As of 2026 Cratex remains operational with a live site and active trading. The exchange does not publish detailed compliance or licensing information and maintains a relatively low public profile compared with larger spot venues, so traders should size positions conservatively, withdraw to self-custody between trades, and confirm asset listings before placing orders.
