Zenlink DEX protocol is the underlying unified and universal cross-chain DEX protocol, enabling parachains to have DEX functionality and quickly share liquidity with other parachains.

In addition, the Zenlink DEX aggregator can connect to all DEX dapps on Polkadot, which together form the Zenlink DEX network with total liquidity.

Great! But how does Zenlink benefit me?

As a Zenlink user, you can access the ecosystem’s total liquidity. You can enjoy low fees, low slippage, and a high-speed trading experience.

Furthermore, you get a perception-free cross chain. In other words, we’re moving closer to the Web3 vision of seamless interoperability between chains. As a result, Zenlink provides you with a natural and convenient cross-chain transaction experience without perceiving multiple chains.

Finally, you get a rich composability DEX experience. Specifically, composability in blockchain technology means developers can freely use and integrate code from other applications into their products. This is because smart contracts — which control application logic — are open-source and available to the public.

In Zenlink’s case, each parachain can build a DEX with its characteristics by connecting to the Zenlink DEX module. As a result, you can easily experience different types of DEXs from Zenlink’s platform.

What is 4pool?

4pool on Astar Network is a specific form of the stable pool comprised of four stablecoins: USDC, BUSD, DAI, and BAI.

When you borrow $BAI from AstridDAO, you can add liquidity to 4pool on Zenlink and stake 4pool LP tokens to the LP Farm on Zenlink to earn rewards.

In short, you can go on 4pool and…

1. Add liquidity to get LP tokens, and then

2. Stake your LP tokens.

Why is 4pool important?

In the standard stable swap design, there are basepools and metapools. The basepool is the largest stablecoin liquidity pool, holding only the three to four biggest stablecoins (e.g., USDC-BUSD-DAI-BAI 4pool). And metapools allow for one token to trade with the basepool.

Stablecoins in the basepool have the best price stability and least system risk in the ecosystem. Additionally, the stablecoins listed in the basepool will have the most significant stablecoin liquidity and most transaction volume since all transactions in the metapool go through the basepool.

This also provides stablecoin holders in the basepool with the best yield opportunity and smoothest user experience. Their vision is to build USDC-BUSD-DAI-BAI 4pool as the basepool for the Astar ecosystem and further expand the BAI universe.

As the two DeFi infrastructures in the Astar ecosystem, they will work with AstridDAO to expand the use cases of the Astar ecosystem’s native stablecoin, BAI, and further enhance the community’s DeFi experience through synergies that will drive the Astar ecosystem forward.

As part of the first phase of partnership:

• Zenlink will adopt $BAI as the base stablecoin of 4pool (the other 3 stablecoins are USDC, BUSD, and DAI) to promote $BAI adoption and provide a revenue stream for $BAI holders.
• AstridDAO will add $ATID rewards to Zenlink 4pool.
• Zenlink and AstridDAO will work together in terms of marketing and community building to create synergies and achieve remarkable growth.

In addition, they will explore collaboration on BAI’s mint collateral, which is just the beginning, and they leverage the combinability and scalability of protocol to provide the Astar community with more diverse DeFi products and benefit from it.

After borrowing $BAI from AstridDAO, users will be able to add liquidity to 4pool on Zenlink and then you can stake 4pool LP tokens to the LP Farm on Zenlink to earn rewards. You can refer to this tutorial: https://wiki.zenlink.pro/zenlink-dex-dapp/hybrid-amm#user-guide

Notice that AstridWASTR on AstridDAO and WASTR (0xAeaaf0e2c81Af264101B9129C00F4440cCF0F720) on Zenlink are different. If you wrap ASTR at AstridDAO, please visit AstridDAO APP to convert AstridWASTR to ASTR and re-wrap at Zenlink.

About AstridDAO

AstridDAO is a decentralized money market and multi-collateral stablecoin protocol. Built on Astar and for the Polkadot ecosystem. It allows users to borrow $BAI, a stablecoin hard-pegged to USD, against risk assets at 0% interest and minimum collateral ratio. This means you can use the value in your risk assets without having to sell them.

The Zenlink Hybrid AMM smart contract has passed PeckShield’s security audit, and you can read the full audit report here, and scroll down to learn everything about the Zenlink Hybrid AMM.

Stable Pool Info

The launch of Zenlink Hybrid AMM means that Stable AMM will be available and the 1st 4pool standard curve on Dotsama will be live.

Swap Fee: There is a 0.05% fee on each transaction using the Stable AMM. 50% goes to the liquidity provider, 30% is used to buyback ZLK, and 20% goes to the treasury.

Amplification Coefficient: Higher values widen the range of low-slippage fees, while lower values help keep the pool’s composition balanced.

Flashloan: Zenlink Stable AMM will support the flashloan feature.

Stable Farms

To help Stable AMM build more liquidity while providing users with stable DeFi gains, Stable Farms will also be launched, with 4pool being activated first (more pools will be added later). This will need to be elaborated separately for both networks:

• The 4pool on Moonriver is a new curve pool consisting of USDT+USDC+xcAUSD+FRAX (USDT, USDC bridged by Multichain)
• The 4pool on Moonbeam is a new curve pool consisting of madUSDT+madUSDC+xcAUSD+FRAX.

Users on both networks provide liquidity to the pool with any combination of the above 4 stablecoins to obtain 4pool LP tokens for earnings.

Doing Swaps using the Hybrid AMM

With the introduction of Hybrid AMM, each transaction will automatically connect Standard AMM and Stable AMM via Zenlink Smart Order Routing to select the best trade path for the user, who will be able to view the trade path at the bottom of the trading window.

About ZenLink

Zenlink is building a new generation of cross-chain DEX network. By integrating the Zenlink DEX Module, Zenlink can enable parachains to quickly possess DEX capabilities and share liquidity with other parachains; Zenlink DEX aggregator can link all DEX DApps on Polkadot.

About Moonriver

Moonriver is a companion network to Moonbeam and provides a permanently incentivized canary network. Once proven, the same code ships to Moonbeam on Polkadot.

About Moonbeam

Moonbeam is much more than just an EVM implementation. It’s a highly specializing Layer 1 chain that mirrors Ethereum’s Web3 RPC, accounts, keys, subscriptions, logs, and more.
