Understand Berachain Ecological Stable Coin Cross-chain Project Polaris | Super early project attention

On February 27, Sky (former MakerDAO) officially announced the launch of Polaris on the X platform. However, except for this announcement, Polaris has almost nothing at present - the official website has not been online, the white paper has not been released, and even the official Twitter account has not posted a tweet.

But if you put aside these superficial "blanks", the story behind Polaris may be worth exploring. Polaris is launched by Sky and builds a DeFi ecosystem based on Berachain. The project plans to integrate USDS stablecoins into Berachain to build a "fully autonomous liquidity system" and inject liquidity support into the Berachain ecosystem.

What problem is Polaris trying to solve?

Berachain is known for its unique Proof of Liquidity (PoL) mechanism that not only incentivizes users to provide liquidity to the network, but also ensures that assets can still be circulated in the DeFi protocol. This time, Sky deeply integrates USDS into Berachain through Polaris to make the most of this mechanism.

According to the preliminary plan, Polaris' core goal is to expand the cross-chain liquidity of USDS, so that holders can participate in lending, trading and income agriculture in the Berachain ecosystem, and further improve the capital efficiency of the DeFi ecosystem.

Sky has undergone significant evolution since its inception. Initially, it was born on the Ethereum blockchain and attracted widespread attention for the launch of the decentralized stablecoin DAI (now USDS) in 2017, becoming one of the earliest US dollar-anchored stablecoins. Today, Sky mainly runs in the Ethereum ecosystem, and its core infrastructure still relies on Ethereum and is built around USDS stablecoins and SKY governance tokens - both of which are the successors of DAI and MKR in the MakerDAO era.

In the Sky ecosystem, the Agent Framework supports multiple "Stars" and provides infrastructure support for tokens and their decentralized applications.

The launch of Polaris is the latest case of the implementation of this framework. Polaris uses Sky's US$7.5 billion USDS asset pool, combined with Berachain's Proof of Liquidity (PoL) mechanism to achieve cross-chain liquidity expansion.

Sky founder Rune Christensen said: "When the project has the founding team and capital, the Sky agency framework can greatly improve execution speed, and this cooperation will also demonstrate Sky's ability to expand in an emerging ecosystem. More projects will be launched this year." Polaris is the first officially announced "Star" since Spark's release two years ago, and the ecosystem may usher in larger scale expansion in the future.

What Polaris launches:

• Strengthen the liquidity of the Berachain ecosystem . Berachain relies on the liquidity proof (PoL) mechanism to operate, and the addition of Polaris means that USDS, an important stablecoin, officially enters the Berachain ecosystem, increasing overall market activity.
• Expand the application scenarios of USDS . With the help of Polaris, the circulation range of USDS has been expanded to Berachain, which not only enhances USDS's influence in the multi-chain DeFi ecosystem, but also makes it an important transaction medium for the Berachain ecosystem.
• Promote the implementation of the Sky Agent Framework . Polaris is a "Star" project built on the Agent Framework under the Sky ecosystem. After Polaris operates successfully, Sky may accelerate the launch of more DeFi solutions based on the framework.
• To promote the improvement of DeFi capital efficiency , liquidity in the traditional DeFi ecosystem is often limited by the fragmentation of liquidity in a single chain, and the "completely independent liquidity system" that Polaris is trying to build can achieve a more efficient capital cycle.

Polaris may be just the first step in Sky's expansion strategy. With the advancement of 2025, the successive appearance of more "Stars" in the Sky ecosystem is exciting, and Polaris, as a pioneer, will undoubtedly play a key role in the future development of DeFi.
