What is Zenlink?

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:

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

1. Module - 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.

2. 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.

3. 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.

Zenlink DEX DApp - 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.

Zenlink Token - The native token of Zenlink DEX Protocol which can be used to distribute liquidity benefits, governance, etc.

Zenlink SlotVault - Zenlink SlotVault is a smart pool product created by Zenlink to support more parachain projects bidding slots and to meet the demand for more non-parachain projects to participate in PLO.

How does Zenlink work?

Step 1

Deploy Zenlink DEX Module, WASM and EVM into parachains with one click and interconnect them

Step 2

Find the best trading path through all parachain liquidity sources with Zenlink Smart Order Routing and aggregate other DEX liquidity with Zenlink DEX Aggregator

Step 3

Users can easily complete efficient, well-priced, and low-slippage swap with Zenlink DEX

Architecture

Learn about the architecture of Zenlink DEX Protocol.

Parachains on Polkadot are essentially a collection of completely independent and freely programmable Runtime Modules. Compared with Ethereum's smart contract, parachains are more completely isolated, and the running calculations between parachains can be independently parallelized. This allows Polkadot's comprehensive performance to increase by several levels, but it will also make the interaction between parachains more complicated.

The team led by Gavin is vigorously developing the communication protocol XCMP on the parachains, but even if the development of the XCMP protocol is completed, we still need to develop various application-related general protocols on the XCMP protocol. Zenlink DEX Protocol is to implement a protocol for parachains to interoperate and share the liquidity pool.

The cross-chain protocol on Polkadot can be compared to the traditional TCP/IP protocol. The XCMP protocol is similar to the data link layer on TCP/IP, which solves the transmission function of the indiscriminate perception protocol between each chain (route).

Zenlink DEX Protocol is similar to the application layer on TCP/IP. As long as each parachain implements Zenlink DEX Protocol, it can share all the liquidity pool of parachains on Polkadot.

Zenlink DEX functionalities can be imported into parachains in the following three ways.

1. Integrated with parachains as a substrate module.

2. Deployed to the Wasm Contract module on parachains.

3. Deployed to the EVM Contract module on parachains.

Zenlink has specifically implemented the above three ways to facilitate the parachains one-click integration of Zenlink DEX Protocol.

Zenlink SlotVault Overview

Zenlink SlotVault is a smart pool product created by Zenlink to support more parachain projects bidding slots and to meet the demand for more non-parachain projects to participate in PLO.

Zenlink SlotVault will allow users to choose the allocation of funds according to the income rate to participate in the crowdloan of parachain projects so as to obtain multiple token benefits from the crowdloan sponsors and their supporting projects. It will encourage more users to participate in parachain projects crowdfunding, which in turn will increase the success rate of parachain project bidding slots.

In particular, Zenlink will provide support for all parachain projects that join Zenlink SlotVault, and airdrop ZLK for all users who lock KSM/DOT through Zenlink SlotVault to support parachain projects in their slots bidding as an additional incentive.

ZLK Distribution

Zenlink will issue the same set of ZLK Token in Kusama Network and Polkadot Network with a maximum supply of 100 million. Due to the buyback mechanism, there will be a certain degree of deflation, and the actual maximum circulation will be less than 100 million. The token distribution ratio of the two networks is tentatively 40% of Kusama issuance and 60% of Polkadot issuance, following the same distribution rules (i.e. 40,000,000 ZLK issued on the Kusama network and 60,000,000 ZLK issued on the Polkadot network, which will follow a non-discriminatory release rule). The specific distribution is as follows:

Community: 50%, of which:

- Trading mining: 15%, non-linear unlocked.

- Liquidity mining: 25%, non-linear unlocked.

- DAO Treasury: 5%, used on demand for network construction expenses and is jointly controlled by the community and Zenlink team.

- Community Incentives: 5%, which is used to reward ZLK active community contributors and parachains that integrate Zenlink DEX Module.

Early investors: 26%, of which:

- Seed round: 7%, linearly unlocked every 3 months, 1/8 unlocked each time

- Angel round: 11%, linearly unlocked every 2 months, 1/8 unlocked each time

- Series A Round: 8%, linearly unlocked every month, 1/8 unlocked each time

Team: 20%, linearly unlocked every 3 months and released in 24 months (No unlocking for the first 2 months after launch).

Zenlink Foundation: 4%, reserved and there is no plan to unlock for now.

FAQ

Zenlink's frequently asked questions

What is Zenlink?

Zenlink is a cross-chain DEX network based on Polkadot, which is committed to building an ultimate, open, and universal cross-chain DEX protocol for building DEX on Polkadot with one-click.

A more graphic expression would be that Zenlink is the one-stop shop for trading Polkadot assets, the DEX Composable Hub between all parachains.

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

- Zenlink DEX Protocol

- Zenlink DEX DApp

- Zenlink Token

What is the native token of Zenlink?

Zenlink native token is $ZLK, which provides a fair and transparent governance mechanism and reasonable value capture methods to incentivize ecosystem users to participate in long-term network development.

Why no public sales?

Zenlink has received a $1.1M angel investment led by Hashkey in September 2020 and completed Series A funding led by Alameda Research in September 2021.

The team has no plans to raise funds other than those needed to support the development of the project, so a public sale is not contemplated and will distribute $ZLK tokens in a more equitable manner, such as liquidity mining.

How to get ZLK?

There are several ways to get $ZLK:

- Participate in the giveaway events launched by Zenlink and its partners. Zenlink has already launched several giveaway events till now, and rewards for the giveaways held prior to the launch of Zenlink have all been distributed. There will be more events in the future, stay tuned!

- By locking in DOT/KSM through Zenlink SlotVault to support Zenlink's partner bid slots, a portion of the ZLK distribution will be completed in that session. The benefit to users is the ability to receive both token distributions from parachain projects bidding for slots and ZLK airdrops.

- Participate in ZLK liquidity mining, trading mining, and invite to earn. 50% of ZLK tokens will be distributed to the community, which will be done through liquidity mining, trading mining, etc.

- Join the Zenlink DAO Governance Organization. ZenlinkDAO bootstrapping governance has been launched and ZenlinkDAO governance board members can make suggestions on Zenlink's development plans and also participate in ZLK liquidity mining in the early stages.

- Buy ZLK in the open market.

What is Zenlink’s team information?

As of now, the Zenlink team is mainly based in China and Singapore, and all team members have many years of experience in the blockchain industry. Its core members come from imToken and are also early supporters of Polkadot.
