OKB is a cryptocurrency of the OK Blockchain Foundation and Odex. The exchange currently ranks third in terms of liquidity, fourth in terms of trading volume and provides a wide range of trading pairs. OKB exchange tokens have several features: they are built on the Ethereum blockchain and are tokens of the ER20 standard, the procedure for burning tokens makes them deflationary assets, there are special opportunities on exchanges for token holders.
