Trading Pairs

All major pairs will be listed on eosfinex including BTC/USD, ETH/USD, EOS/USD etc. to assist in the expansion of more token offering as quickly as possible. The exchange’s smart contract will be flexible enough to allow creation of any trading token by a trusted contract. Anyone can add a new pair easily after a new tradable token is issued by the trust contract.


EOX is the sidechain native token of eosfinex, needed for the allocation of RAM, CPU and network resources for users to do trading. Users stake EOX to reserve CPU and network bandwidth of its sidechain to be able to send transactions, for example, to place and cancel orders. EOX is needed as well by users to buy sidechain RAM, which is used to store resting orders in order books and data of custom user contracts.
