How is it all possible

A unique combination of multiple state-of-the-art technologies like blockchain, Polkadot parachains, TEE, Polkadex Orderbook is at the cutting edge of innovation in DeFi.

Essentially, Polkadex Orderbook is a Layer 2 SubstraTEE (an abstraction layer for the Substrate framework of the SGX Trusted Execution Environment) scaling solution on top of the Polkadex network. Interesting fact: Polkadex is not only the first project to use the Substrate Abstraction Layer for SGX technology to build a decentralized exchange, but it is also one of the first use cases of this technology in general.
