Chainlink integrates data feeds with Polygon zkEVM
Share this article
ChainLink has integrated its data feeds for Polygon zkEVM, which now has direct access to external pricing data. The integration, announced on December 15th, will allow smart contracts on Polygon to receive data safely and securely off-chain, enhancing functionality and expanding the network's use cases.
Chainlink Data Feeds utilizes more decentralization at the cost data, mouth node, and mouth network levels. This design ensures a level of resilience against API failures, out-of-flash crashes, and data manipulation attacks such as flash-loan exploits.
Like Polygon Labs, developers building on Polygon's zkEVM can access an environment that is fully compatible with EVM (Ethereum Virtual Machine) at the bytecode level. Most Ethereum-native tools and infrastructure can be used out of the box, requiring minimal changes. With the integration, developers on Polygon zkEVM can use Chainlink feeds to rapidly develop and deploy dApps.
“Chainlink Oracles open up many DeFi applications, bringing the possibility of new dApps that truly serve ZK Pack's unique value propositions, including faster finality and stronger security,” said Marc Boyron, CEO of Polygon Labs.
Polygon zkEVM uses Zero Knowledge Proofs (ZKPs) to encapsulate off-chain transactions for more efficient on-chain verification. ZKPs enable transaction volume through zk-rollups, whereby multiple transactions are made off-chain and then encrypted together on-chain. This batch verification approach maximizes throughput and reduces gas bills rather than filing each transaction individually. By streamlining authentication, Polygon zkEVM unlocks scalability for Ethereum-based dApps.
Like Polygon Labs, Polygon zkEVM maintains compatibility with EVM throughout the stack, making it easier to use and deploy for Ethereum-based applications. This also maintains the important security features that decentralized financial protocols require.
“Security is essential to the long-term vision of any DeFi protocol,” said Johan Eide, Chief Business Officer of Chainlink Labs.
Specifically, Polygon recently announced that it is ending support for contributions to Polygon Edge, which aims to build a custom Ethereum-compatible blockchain. According to the company, it did this to allow it to focus on Polygon CDK, a similar solution developed by the company to strengthen its efforts to future-proof the Polygon network.
At the time of writing, LINK is at $14.32, up 0.3% in the last 24 hours, while POL and MATIC are at $0.78, down 6.5% in the last 24 hours.
