Zenlink DEX Protocol Coming to External Code Audit | Zenlink Monthly Update(June 2021)

In June, the Zenlink team focused on product development, and after Zenlink DEX Protocol successfully implemented three different versions of Module, WASM and EVM, we optimized and upgraded the features of each version, and Zenlink DEX Procotol will soon enter the external code audit stage.

As for Zenlink SlotVault, the first batch of cooperative projects have basically been accessed, and the mobile adaptation has also been completed to facilitate users’ access and use.

The following are the details of the June update.

Technology/product progress

Notes: Zenlink mainly consists of two core parts: Zenlink DEX Protocol and DApp. Zenlink Protocol will implement a simple, highly versatile and pluggable DEX Module, which can enable parachains to access DEX capabilities after the Module is deployed on the parachain in a plug-and-pull manner; at the same time, we will also create an efficient DEX dedicated cross-chain protocol to realize the liquidity sharing between the DEX Module on different parachains.

Zenlink DApp is a front-end interactive product based on Zenlink DEX Protocol to facilitate users to use cross-chain DEX without awareness.

SlotVault is a smart pool product built by the Zenlink team in combination with PLO (Parachain Lease Offerings), which aggregates many parachains projects and other Polkadot eco-projects. The development progress will be disclosed around the above three parts.

DEX Protocol

  • Additional refinements to the test user and code structure of the Zenlink DEX Protocol EVM version, and upcoming external code audit work.
  • Optimized and improved API interface services related to the EVM version, including transaction notifications, balance inquiries, transaction liquidity inquiries, etc.
  • The interface for adjusting trading fees is reserved. The revenue of ecological participants (traders, parachains, LPs and market makers, etc.) will be enhanced by means of incentives to help Zenlink’s ecological development.


  • Through modeling abstraction and architectural reorganization, the DEX DApp has been able to access two different implementations of the DEX Protocol (EVM version and Module version) simultaneously. This will effectively smooth out the cognitive friction and improve the user experience, allowing users to migrate smoothly from the former single-chain DeFi ecosystem to the complex multi-chain Polkadot DeFi ecosystem.
  • Since the mechanism of the Zenlink DEX Protocol EVM version is very different from the Module version, the DEX DApp has made a round of adaptations for the EVM version, including the switch of account addresses and the addition of a transaction approve process.
  • By using the Batch Transaction feature that comes with the Polkadot network, we were able to accomplish the “Approval + Swap” function in one-click.

SlotVault DApp

  • The first batch of partner projects are basically all connected to Zenlink SlotVault, and users will experience different paths for each project with different mechanisms.
  • The mobile adaptation of Zenlink SlotVault is completed. Users will be able to access SlotVault directly from decentralized mobile wallets such as imToken, Math Wallet and TokenPocket.
