What you need

All you need to trade on Polkadex Orderbook is a Polkadex network account with some PDEX in it!

Polkadex Orderbook runs on the Polkadex network, a Substrate-based blockchain custom-built for the Polkadex Orderbook Layer 2 Trusted Execution Environment (TEE). That means you’ll need a Polkadex network account with PDEX balance in order to trade on Polkadex Orderbook.

• Download the Polkadot.js browser extension and import your Polkadex account or create a Polkadex account if you don’t have one already.
• PDEX is available on KuCoin, Gate.io, AscendEX, and, of course, Polkadex Orderbook

You may also want to have USDT

While all you need is PDEX and a Polkadex account, the existing trading pair available on Polkadex Orderbook is PDEX/USDT. That means, if you want to buy PDEX, you will need USDT on your Polkadex account.

How to get USDT on Polkadex:

• You’ll first need an Ethereum wallet preferably integrated with the MetaMask browser extension
• Secondly, you will need USDT in your Ethereum wallet
• Once you have USDT in your Ethereum wallet on MetaMask, connect to the Polkadex Token Manager interface via your MetaMask and Polkadot.js browser extensions
• Visit the ChainBridge page and select how much USDT you want to bridge from Ethereum to Polkadex
• Approve the USDT spend amount from your MetaMask extension
• Sign the USDT transaction from your MetaMask extension
• That’s it! You have successfully bridged USDT from Ethereum to Polkadex

How to trade

Once you have a Polkadex account filled with PDEX and USDT, you’re ready to trade on Polkadex Orderbook. Here’s a few short guides on how to register for, deposit to, trade with, and withdraw from Polkadex Orderbook

How to register your funding account.

• Sign the registration transaction from your Polkadex account on the Polkadot.js browser extension
• Once your funding account is successfully registered and your trading account has been created, you will see the option to view your trading account’s mnemonic or print it as a paper wallet.
