Frontend Engineer

About Us

Coincall Exchange is a fast-growing crypto derivatives exchange that focuses on options trading, with an obsession for ease of use from day one, catering to both new and professional traders. Our platform is user-friendly, featuring zero spread for selected options and we offer a diverse range of altcoin options, including SOL, MATIC, BCH, FIL, and more.

The crypto industry is quickly evolving, and while crypto options are growing, it remains relatively small compared to the size of the overall crypto market. Our experience in TradFi tells us that crypto options trading is still in its early stages of growth. This presents us with an opportunity to offer something different from the already crowded crypto exchange market.
