The expansion of Frax Finance, an innovative decentralized stablecoins and DeFi stablecoin infrastructure, onto Scroll— a native zkEVM Layer 2 for Ethereum. Supported by cross-chain technologies from Axelar and integrated with Sushi, a leading multi-chain decentralized exchange (DEX), this initiative aims to enhance Frax's accessibility and usability across diverse blockchain environments.


Frax offers innovative decentralized stablecoins and DeFi stablecoin infrastructure, featuring a unique model that balances algorithmic and collateralized dynamics. Its multi-chain vision necessitates robust blockchain platforms, Web3 interoperability infrastructure to enable Frax asset transfers across blockchains, and a multi-chain DEX interface to facilitate trading.

Roles of Scroll, Axelar, and Sushi

Given the objectives outlined, Frax has successfully implemented a partnership model with distinct roles for each participant:

  • Scroll: As an L2 solution, Scroll provides faster transactions and reduced costs while preserving the security features of Ethereum, making it an attractive platform for deploying Frax's stablecoins. This facilitates smoother and more economical transactions.
  • Axelar Network: Axelar supplies the necessary cross-chain infrastructure, facilitating a seamless connection between various blockchains with the interchain asset, in this case axlFRAX. This integration allows Frax assets to move freely and securely across different networks, broadening the stablecoin's reach and utility.

  • Sushi: Sushi's involvement is crucial for liquidity. By enabling Frax assets trading on Scroll via its UI, Sushi not only enables trading and LPing for Frax on Scroll but also enables liquidity to flow across the 30+ chains it supports. I.e. you can easily swap $axlFRAX on Scroll to, e.g $Arb on Arbiturm This is vital for establishing a stable market presence across multiple ecosystems.

Outcomes and Benefits

  • Accessibility: Frax's expansion to Scroll, facilitated by Axelar’s cross-chain technology, significantly widens the stablecoin’s accessibility, marking the beginning of its stablecoin  availability on multiple blockchains.
  • Reduced Transaction Costs and Increased Speed: Operating on Scroll, Frax transactions are faster and cheaper, addressing some of the major barriers in blockchain usability.
  • Enhanced Liquidity: Through Sushi, Frax benefits from enhanced liquidity, which is crucial for any stablecoin’s functionality and adoption. The underlying security of Ethereum, maintained via Scroll’s L2 solution, ensures that these transactions remain secure.

A Model for Multi-Chain Expansion: L2 + Interoperable Protocol + Multi-chain DEX

In conclusion, the expansion of Frax Finance onto Scroll, supported by Axelar and integrated with Sushi, showcases a powerful "DeFi Lego" approach in practice. By combining L2 scalability, cross-chain interoperability, and robust DEX capabilities, Frax enhances accessibility, security, and efficiency across diverse blockchain environments. This successful use case sets a model for multi-chain expansion, offering a proven framework for projects seeking comprehensive multi-chain functionality and market presence in the decentralized finance space.
