MegaETH is moving into a new phase of development, with the planned release of the Frontier mainnet beta for builders.
summary
- MegaETH will open the beta version of its Frontier mainnet to developers next week.
- The month-long beta focuses on stability testing, early app adoption, and real-time performance trials.
- Recent bridge issues have been resolved with full refunds as the network prepares for a full mainnet launch in early 2026.
MegaETH is preparing to open a beta version of its mainnet, known as Frontier, to developers next week. The December 8th update on X confirmed that the infrastructure team has already begun rolling it out to networks.
The team said it will now move to a phased rollout to support builders first, followed by extensive application testing and gradual user onboarding in the coming weeks.
Frontier enters month-long beta
Frontier is the final step before MegaETH’s full public mainnet and is configured as a one-month beta starting in early December. This phase is tailored for developers, early adopters, and teams who want to test real-time execution features such as sub-millisecond latency, in-memory processing, and just-in-time compilation of smart contracts.
Next week, we will open Frontier to app builders.
Our infrastructure team has already deployed to mainnet, and more will arrive in the coming days.
We then spend several weeks deploying and testing supporting applications prior to user onboarding.

MegaETH describes this period as a stability-first phase with no incentives, and a short period of downtime is expected as performance limits are pushed. In your project, you want builders to be able to run your application in conditions that are close to your real-world environment.
This is also the point where the team collects feedback from selected partners and infrastructure providers who have already migrated to the network. If the testing period goes as planned, the full mainnet launch could begin as early as January 2026, completing two years of construction for what MegaETH calls “real-time Ethereum.”
Gaining momentum after a volatile November
The beta version begins after a busy period for the project. Frontier was first announced in mid-November as a public testing milestone for a high-performance Layer 2 designed to support more than 100,000 transactions per second.
The run-up to Frontier included a pre-deposit bridge launched on November 25th to allow users to load USD Coin (USDC) collateral ahead of mainnet. This bridge was suspended almost immediately due to a configuration issue.
MegaETH has committed to refund all deposits by November 27th and to undergo an audit and redesign the bridge before restarting it. The decision gained support across the community, who viewed the refund as a sign that the team was unwilling to compromise on safety.
The frontier will be the next controlled environment where new experiments will converge. For MegaETH, the next month will determine how close it gets to achieving real-time performance in production.
