Polkadex Orderbook is live

The CEXier DEX is here: non-custodial cryptocurrency trading just got a whole lot better

What is Polkadex Orderbook?

If you’re new here or just want a recap, let’s take a step back. In short, both centralized exchanges (CEXs) and DEXs are imperfect in their current forms. Polkadex Orderbook combines the best of both worlds. How? Keep reading to find out!


DEXs like Uniswap have revolutionized the way cryptocurrency is traded in recent years by giving traders control over their own funds. The automated market maker (AMM) model popularized by such DEXs, however, has been plagued by crazy-high network fees, price slippage, front-running, low interoperability, and limited functionality. Because of this, many traders have opted to continue using the advanced trading features and higher interoperability offered by CEXs, which also come at a lower cost to the user. It makes sense; why would you jump through more hoops and spend valuable money on network fees along the way, when all you want to do is trade crypto? However, while the trading experience may be better on CEXs, it may also be riskier due to the possibility of hacks and data breaches. After all, when using a CEX, you’re handing over the custody of your crypto to a third party and hoping they will take care of it.

Enter Polkadex Orderbook

Polkadex Orderbook is built to eliminate these trade-offs. It combines the advantages of CEXs and DEXs while tackling the issues of both. In short, it brings together the speed, functionality, interoperability, and overall look and feel of a CEX with the security and individual custody of assets pioneered by existing DEXs.

Better Lookin’

Limit and market orders

We hate slippage too. Get the price you want with limit orders. Market orders are executed instantly and transparently with better liquidity.

Truly cross-chain

Trade Polkadot and Polkadot parachain tokens through the Polkadex parachain (connecting soon), and Ethereum ERC-20 tokens through ChainBridge and the soon-to-come THEA bridge, which will first connect Polkadex with Ethereum followed by other blockchain networks down the line.

Register multiple trading accounts

Use your desktop, mobile, tablet, or any other device and trade wherever, whenever.

Let bots trade

Integrate a bot from popular trading bot providers like Hummingbot to automate trading and earn from liquidity mining. Pick a strategy and let a robot do the heavy-lifting!


Whether it’s an algorithm or a fund manager, delegate your asset-trading to a third party while keeping control of your funds and sit back and watch your profits roll in.

How’s it all possible? Architecture deep-dive

The secret sauce which makes all these features possible is Polkadex Orderbook’s unique combination of blockchain and trusted execution environment (TEE) technologies. In fact, Polkadex is the first project to use the Substrate Abstraction Layer for SGX to build a decentralized exchange, with Polkadex Orderbook one of the first retail use cases of this technology.

What’s next?

For the first few months of release, Polkadex Orderbook will only support the PDEX/USDT trading pair. PDEX will come directly from the Polkadex network as its native token while traders will bring USDT from Ethereum and back via ChainBridge. Polkadex Orderbook will later replace ChainBridge with THEA, our own custom-built decentralized interoperability solution, and connect to the Polkadex parachain. These connections will ensure assets from both Ethereum and Polkadot (including fellow Polkadot parachains) are tradeable in a single, non-custodial platform and will make Polkadex Orderbook the first interoperable non-custodial exchange capable of high frequency trading.
