What is Zenlink

Learn about the components of the Zenlink DEX Network.

Zenlink is an underlying cross-chain DEX protocol based on Polkadot, and is committed to become the DEX composable hub of Polkadot. By accessing the ultimate, open and universal cross-chain DEX protocol based on Substrate, Zenlink DEX Protocol enables all parachains to build DEX and achieve liquidity sharing in one click. Zenlink DEX Protocol includes Module, WASM, and EVM implementations, which are flexible and adaptable, allowing for customizable compositions and interoperability with different DeFi modules.

In addition, the Zenlink DEX Aggregator connects all DEX DApps on Polkadot and aggregates liquidity, providing a low slippage trading experience for users. Zenlink DEX Composable Hub enables developers to access the Zenlink DEX Module to build their own unique DEXs, forming a DEX composable hub for the Polkadot ecosystem. Currently, Zenlink has received two rounds of Web3 Foundation Grants and investments from several well-known institutions.

In general, Zenlink DEX Network consists of the following parts:

The top-level unified general DEX protocol that includes the following three implementations:


A Module on Substrate Runtime Module Library (SRML) layer according to the Zenlink Protocol standard. Parachains can integrate with it quickly, so that be able get the DEX function, even share the liquidity with other DEX on other parachains.

EVM Contract

It is a contractual deployment mode adopted in order to be compatible with the operation of the Ethereum EVM, and it is also a transition scheme adopted in the initial stage of the Polkadot network. The Zenlink DEX EVM version implements all the functions of the protocol layer, complements the perfect testing process, and can also be deployed to the parachain of EVM contracts at the first time, which greatly expands the applicability of the platform.

WASM Contract

It is the original contract implementation of Polkadot, and it is also the main contract deployment mode of Polkadot network in the future. The Zenlink DEX WASM version has the ability to deploy to WASM contract platform in the first place, and the applicability of the platform has been greatly improved.


A simple and user-friendly aggregator entrance of DEX world which is able to connect with most of DEX on Polkadot, so that user can do one-click trade with multiple DEX instances on low slippage.
