Polkadex is a decentralised cryptocurrency exchange built on the Substrate framework, designed to leverage the features of the Polkadot network. Created to overcome the limitations of traditional centralised exchanges, Polkadex aims to combine the liquidity and market speed of centralised platforms with the security and transparency inherent in decentralisation. By offering a high-performance, non-custodial trading solution, Polkadex ensures users retain control over their private keys. The platform employs innovative technologies such as a unique node architecture and cross-chain capabilities, facilitating seamless and efficient trading of digital assets. Polkadex also integrates decentralised finance (DeFi) elements, automated trading strategies, and supports a scalable infrastructure, all of which contribute to its goal of making decentralised trading accessible to a broader spectrum of users.
