The exchange is fully decentralized, it is completely controlled by a smart contract deployed on the EOS platform. Everything is on-chain (e.g. transactions, order books). There are many advantages of a true DEX, including transparency, security and reliability.
Immutable smart contract
The exchange has adopted the Temporary Immutability pattern (proposed by xJonathanLEI).
This means that no one will be able to modify the exchange logic or control users' funds manually during the immutable period (even the contract owner will not have the power to modify or control anything).
The exchange supports EOS price that has up to 8 decimal places (Note: most dapps can only support up to 4 decimal places).
This means that users will be able to offer and buy cheaper tokens (i.e. a token can be as cheap as 0.00000001 EOS).
