October 2025—Chainlink and MegaETH today announced the deployment of the first real-time, on-chain data feed oracle on MegaETH, representing an unprecedented protocol-level implementation that can deliver Chainlink's trusted market data to the blockchain with sub-millisecond latency.

This integration directly integrates Chainlink data feeds into MegaETH's execution environment natively through precompilation, allowing any smart contract to seamlessly access real-time, high-frequency market data. The result is the establishment of a new foundation for real-time DeFi, enabling applications such as perpetual contracts, prediction markets, and stablecoins to achieve response times and accuracy comparable to centralized exchanges (CEXs) while maintaining full on-chain composability.

Megaeth Co-Founder and CTO Lei stated, "Integrating Chainlink data feeds at the protocol layer provides developers with low-latency, efficient on-chain market data, which is the infrastructure needed to build the next generation of real-time decentralized financial applications."

Why This Matters

This integration introduces a new kind of oracle model that combines the simplicity of traditional on-chain oracles with the immediacy of data feeds.

Protocol-Level Low Latency: Chainlink data feeds refresh instantly when accessed by contracts, eliminating issues of latency mismatches and redundant updates.

Zero Integration Costs: Any smart contract can directly read real-time market data from the precompilation without needing to build custom off-chain logic.

Future-Proof Data Catalog: Chainlink's extensive network supports various asset classes, including cryptocurrencies, equities, commodities, and real-world assets (RWAs). This will enable the scalability of high-performance DeFi.

The initial deployment focuses on high-frequency cryptocurrency assets, setting a new standard for low-latency on-chain price discovery.

When oracle latency is reduced to single-digit milliseconds and data quality meets institutional benchmarks, DeFi achieves parity with centralized trading infrastructure, enabling real-time settlement, accurate funding rates, and continuously updated derivatives, all secured by Ethereum.

Why Choose Chainlink

Chainlink is the largest and most trusted data provider in the crypto space. Chainlink oracles have supported over $25 trillion in transaction volume, secured over $100 billion in total value locked (TVL), and validated over 18 billion cross-chain messages.

The Chainlink Data Feed is a low-latency Oracle solution built by Chainlink specifically for applications requiring high-frequency market data. The Data Feed is supported by Chainlink's powerful Decentralized Oracle Network (DON), where independent nodes aggregate, validate, and sign each data point before transmission. This pattern ensures data integrity while maintaining real-time updates.

With low-latency, native access to Chainlink's data feeds covering crypto, equities, commodities, and more, various protocols on MegaETH will benefit from infrastructure that surpasses centralized financial latency execution levels.

About Chainlink

Chainlink is bringing capital markets onto the blockchain and underpinning most of decentralized finance (DeFi) as an industry-standard Oracle platform. The Chainlink technology stack provides the fundamental data, interoperability, compliance, and privacy standards needed to drive advanced blockchain use cases, including institutional tokenized assets, lending, payments, stablecoins, and more. Since inventing the decentralized Oracle network, Chainlink has facilitated trillions of dollars in transaction value, currently securing the vast majority of DeFi.

About MegaETH

MegaETH is the first real-time blockchain secured by Ethereum and supported through a hyper-optimized execution environment and heterogenous architecture. It achieves a 10-millisecond block time and up to 100,000 TPS of streaming throughput. Developers can scale applications through real-time state streams, and users can benefit from instant transactions while preserving full Ethereum composability.
