MegaETH Mainnet is Live! — The Next Era of Ethereum Scaling

What It Covers

MegaETH launches mainnet as a high-performance Ethereum layer two achieving 55,000 transactions per second during stress testing. Namik and Lei Yang discuss their differentiated approach using EigenDA for data availability, proximity markets for MEV, USDM stablecoin revenue model, and aggressive app incubation strategy following Vitalik's recent pivot away from traditional rollup-centric roadmap expectations.

Key Questions Answered

• •Extreme throughput validation: MegaETH processed 11.4 billion transactions over seven days during mainnet stress testing, averaging 15,500 TPS with peaks of 55,000 TPS. Total cost was approximately 1.1 million dollars in gas fees, demonstrating sub-penny transaction costs while simultaneously running low-latency onchain games like Crossy Fluffle without UX degradation, proving the infrastructure can handle production-scale activity.
• •State trie redesign breakthrough: The SALT (Small Authentication Large Tries) data structure eliminates 90 percent of traditional block building overhead by fitting entirely in main memory rather than requiring constant database updates. This architectural change allows MegaETH to avoid the database bottleneck that consumes most processing time on standard EVM chains, enabling the extreme throughput levels without sacrificing EVM bytecode compatibility.
• •USDM revenue model: MegaETH captures treasury bill yields from USDM stablecoin balances rather than relying on transaction fees, creating alignment where chain revenue grows with application success and total value locked. This model allows gas fees to remain at cost while generating sustainable revenue, avoiding the misaligned incentive where successful chains become expensive and drive users away to competitors.
• •Proximity market MEV design: Instead of microscopic per-block auctions incompatible with ten-millisecond block times, MegaETH auctions colocation seats on weekly or monthly intervals. Traders purchase virtual machine access next to the Tokyo sequencer, achieving one-millisecond to 100-microsecond latency comparable to Nasdaq high-frequency trading infrastructure, with auction proceeds flowing to token holders rather than private MEV extraction.
• •Stage two reality check: Reaching stage two rollup status requires immutably enshrining governance logic onchain forever, creating existential risk if bugs emerge years later. MegaETH acknowledges this may take five to ten years with formal verification and AI-assisted proof generation, making the stage one security council model more practical for chains prioritizing rapid feature development over theoretical decentralization maximalism.
• •Agent-first blockchain features: MegaETH explores sandboxing primitives allowing users to define transaction constraints in natural language, such as maximum deduction amounts and minimum received tokens, letting AI agents explore solution paths freely within safe boundaries. This approach treats abundant cheap block space and clear transaction specifications as advantages for software agents rather than obstacles, potentially unlocking agent users as the next billion-user cohort.
