Chainlink hits Ethereum layer 2 Arbitrum for cross-chain DApp development

Blockchain oracle network Chainlink has tapped into Ethereum ( $2,454.06 ) (ETH) layer 2 scaling protocol Arbitrum to drive cross-chain decentralized application development.

The two protocols announced the mainnet launch of the Chainlink Cross-Chain Interoperability Protocol (CCIP) on Arbitrum One on Sept .21, giving developers access to Chainlink’s solution that taps into Arbitrum’s high-throughput, low cost scaling.

The combination of CCIP and Arbitrum One’s ecosystem aims to unlock a myriad of use cases, including cross-chain tokenization and collateralization, blockchain gaming, data storage and computation.

Chainlink Labs chief business officer Johann Eid commented on the partnership, highlighting Arbitrum’s role in offloading transaction congestion from Ethereum ( $2,454.06 ) ’s base layer and providing a base to build DApps.

“CCIP now gives these users access to a highly secure and easy-to-use interoperability protocol built on Chainlink’s time-tested infrastructure, powering cross-chain smart contracts in a way that will open up new avenues of growth, accessibility, and innovation.”

The integration will marry Arbitrum’s optimistic rollup technology that currently commands around 60% of total value locked in the wider Ethereum ( $2,454.06 ) layer two ecosystem. Arbitrum facilitates fast and low fee transactions that are batched off-chain and then submitted to Ethereum ( $2,454.06 ) ’s base layer.

The optimistic rollup is assumed to be valid until proven otherwise by validators of the network.

Meanwhile CCIP allows developers to build cross-chain DApps that use arbitrary messaging and simplified token transfers. This taps into Chainlink’s decentralized oracle network that enables smart contracts to securely access off-chain data sources, APIs, and payment systems.

The protocol allows smart contracts to interact with real-world data and events, making it possible for them to be triggered by data from external sources.

Another prominent Ethereum ( $2,454.06 ) scaling technology firm in StarkWare previously tapped into Chainlink’s oracle services. As Cointelegraph previously reported, StarkWare’s zero-knowledge proof rollup protocol StarkNet integrated Chainlink’s data and price feeds for its ecosystem in February 2023.
