MegaETH Launches Real-Time Mainnet With 10 Millisecond Blocks, Raising the Bar for Ethereum Scaling

MegaETH officially launched its mainnet on Monday, introducing what it calls a “real-time blockchain” designed to dramatically reduce latency while maintaining Ethereum-level security. At launch, the network supported more than 50 live applications, marking a major milestone for a project that has positioned speed and responsiveness at the center of its design.

uThe team behind MegaETH claims the network can process more than 40,000 transactions per second with block times as low as 10 milliseconds. If sustained in production, those figures would place MegaETH among the fastest blockchain systems currently operating, particularly within the Ethereum scaling ecosystem.

MegaETH is real-time Ethereum, streaming transactions at lightning speed: sub-millisecond latency and over 100,000 transactions per second.

Tackling latency head-on

According to MegaETH, the primary limitation in blockchain user experience today is not throughput alone, but latency. To address this, the project developed a new architecture built around a system known as SALT, short for Small Authentication Large Trie. The approach keeps critical data in memory, reducing reliance on slower storage operations that can delay transaction processing.

Rather than positioning itself strictly as a layer 1 or layer 2 network, MegaETH separates execution from settlement. Ethereum is used for security and final settlement, while MegaETH focuses on high-performance execution. The team says this structure allows it to push beyond the performance limits of more traditional blockchain designs.

“The goal was never to be an L1 or an L2,” the team said in a statement. “The goal was to build the most performant chain possible.”

From testnet to mainnet

Founded in 2022, MegaETH has moved quickly from concept to launch. The project raised $20 million in a seed round led by Dragonfly Capital in June 2024, with participation from Ethereum co-founders Vitalik Buterin and Joseph Lubin.

Before Monday’s launch, MegaETH ran a testnet in 2024 and followed it with a large-scale stress test in January. That week-long exercise aimed to process 11 billion transactions to measure how the network performed under sustained demand. The mainnet debut also follows an oversubscribed public token sale in October 2025, which attracted $1.39 billion in commitments.

New applications and interaction models

MegaETH argues that ultra-low latency opens the door to applications that are difficult or impossible to run on slower blockchains. These include new types of onchain assets and more interactive user experiences, such as real-time games, tap-based interfaces, and walletless interactions.

Its in-house accelerator, MegaMafia, has already supported several development teams. According to the project, those teams have collectively raised more than $70 million from investors including Franklin Templeton, Robot Ventures, Maven11, and Figment Capital.

Token launch tied to performance

In a notable departure from common industry practice, MegaETH has separated its mainnet launch from the release of its native MEGA token. The token will only be generated seven days after the network meets at least one of three predefined performance benchmarks.

These include maintaining a $500 million circulating supply of the USDM stablecoin over a 30-day average, having 10 MegaMafia applications active on mainnet, or seeing three applications consistently generate more than $50,000 in daily fees for 30 consecutive days.

The project says its token economics are closely linked to network usage. One mechanism, called Proximity Markets, allows users to lock MEGA tokens to gain colocated sequencer access and reduce latency. Another uses yield from the USDM stablecoin to buy back and remove MEGA tokens from circulation.

Looking ahead

With its mainnet now live, MegaETH enters a crowded and competitive Ethereum scaling landscape. Its focus on real-time performance and measurable adoption milestones sets it apart from many peers, but the true test will be how developers and users respond as activity grows.

For now, the launch signals a broader push within the blockchain industry to move beyond raw throughput claims and toward systems that feel faster and more responsive in everyday use.
