The non-custodial, CEX-like orderbook DEX for DotSama & beyond.

What is Polkadex?

Polkadex is a DeFi DEX (decentralized exchange) designed with the use of Substrate framework technology and integrated within the Polkadot ecosystem. It features distinct advantages:

  • High-Performance Trading: Offers trading performance comparable to centralized exchanges by supporting up to 500,000 transactions per second.
  • Decentralized Orderbook Model: Supports limit orders, market orders, and high-frequency trading. This represents a shift from the typical automated market maker (AMM) model used by many DEXs, offering a unique approach in the market.
  • Non-Custodial Trading: Ensures users never lose control of their funds, mitigating risks from potential exchange hacks.
  • Cross-Chain Liquidity: Utilizes Polkadot’s interoperability to facilitate smooth trading of assets from different blockchains, effectively addressing the issue of liquidity fragmentation.
  • IDO Platform for the Polkadex Order Book: Provides a user-friendly trading environment and a platform for initial DEX offerings (IDOs), ensuring secure fundraising and token sales.
  • PDEX Token: The native utility token used for governance, paying transaction fees, and staking. It enables holders to participate in decision-making and benefit from reduced fees.


Polkadex aims to bridge the gap between centralized and decentralized financial services by creating an effective, safe, and user-friendly trading environment. Despite challenges related to scalability, security, and adoption in the DeFi ecosystem, Polkadex is committed to continuous development and innovation to enhance its offerings.
