Chainlink taps MegaETH for first native, real-time oracle to power next-gen DeFi

Chainlink has chosen MegaETH to host what the companies say is the first native, real-time onchain oracle. 

The rollout aims to transform MegaETH’s “real-time” Ethereum L2 into a venue where perpetuals, prediction markets, and stablecoins can update as quickly as centralized venues, while remaining fully composable onchain. 

According to details shared with The Block, the integration wires Chainlink Data Streams market data into MegaETH’s execution environment so any contract can read high-frequency prices “just-in-time.”  The goal is to trim redundant updates and oracle lag, which is a long-standing bottleneck for on-chain derivatives, by only fetching fresh data as needed.

“Integrating Chainlink Data Streams at the protocol level gives builders access to low-latency, efficient market data on-chain,” MegaETH co-founder and CTO Lei Yang said in the announcement.

Chainlink Data Streams is often touted as a critical system for blockchain-based perps, funding-rate calculations, and real-time settlement on ultra-fast chains.

MegaETH pitches itself as a high-throughput Ethereum L2 with fast block times, targeting up to 100,000 transactions per second, which positions the chain for trading apps that require exchange-like responsiveness.

Chainlink, widely used across DeFi and tokenization pilots, has recently claimed that its oracle infrastructure has secured about $90–$100 billion in total value locked (TVL), enabled 10s of trillions in onchain transaction value, and delivered approximately 18 billion verified messages across networks.

Oracles sit at the heart of DeFi, bridging offchain data, such as prices, rates, and reference feeds, to onchain applications. Traditional push oracles publish updates at intervals, creating latency/MEV trade-offs.

The move extends a busy run for MegaETH. In September, the project introduced USDm, a native stablecoin built with Ethena to subsidize sequencer fees and support “real-time applications. Additionally, ecosystem teams have begun raising capital for latency-sensitive products, such as the MegaETH-based derivatives venue Euphoria, which has raised $7.5 million across pre-seed and seed rounds.
