Cross-chain innovation and DeFi

This week the Nervos Foundation and Linear Finance, announced a partnership to integrate Linear’s cross-chain compatible, decentralized asset protocol, which allows for creating, trading, and managing synthetic assets. The two teams are working toward a common goal of a more interconnected blockchain ecosystem, which will be important in assuring the continued growth of the DeFi space.

As we shared last week, the unique properties of Nervos CKB open up new kinds of opportunities for interoperability solutions and the user experience of blockchains as a whole. Linear Finance will be integrating cross-chain swaps of the Ethereum-based LINA token (great name!) and synthetic assets according to the Nervos sUDT standard, as well as utilizing Nervos Layer 2 aggregation solutions to improve throughput and reduce fees with batched transactions.

As cross-chain transactions and the number of assets wrapped between chains increases, stay tuned for all of the innovation coming out of the Nervos project, as the vision for Interoperability 2.0 is realized.
