MegaETH is an Ethereum Layer 2 that targets real-time performance through mini-blocks and a high-performance sequencer, settling on Ethereum. Its token is MEGA.
MegaETH launched its public mainnet in February 2026 as an Ethereum Layer 2 built for very low latency, describing itself as a real-time blockchain. It produces small mini-blocks in fractions of a second through a single high-performance sequencer, then settles batches on Ethereum, and it uses EigenDA for data availability. Here is how it works and what it is used for, not the price.

MegaETH is an optimistic rollup, meaning transactions are treated as valid unless challenged during a dispute window, with final settlement on Ethereum. Execution is handled by a single high-performance sequencer that orders and runs transactions into mini-blocks roughly every ten milliseconds, while separate prover and full-node roles verify results. Transaction data is published to EigenDA, a data availability layer, rather than directly to Ethereum calldata, which lowers cost.

Mini-blocks
MegaETH produces very small blocks in fractions of a second and bundles them into larger blocks for settlement, which is how it aims to give near-instant feedback to users.
Specialized roles
Work is split between a sequencer that orders and executes transactions, provers that generate verification, and full nodes that check results, so each role can run on hardware suited to its task.
EigenDA data availability
Transaction data is posted to EigenDA, a separate data availability layer, instead of Ethereum calldata. This reduces the cost of publishing data, the main driver of Layer 2 fees.
EVM compatibility
MegaETH runs an EVM-compatible execution environment, so Ethereum contracts and developer tools work on it with little or no change.
Ecosystem & usage
What MegaETH is used for.
MegaETH targets applications that need low latency, with DeFi, trading, and gaming projects deploying around the mainnet launch.
MegaETH is an Ethereum Layer 2 that targets real-time performance. It uses a high-performance sequencer to produce mini-blocks in fractions of a second and settles transactions on Ethereum. Its token is MEGA.
What makes MegaETH fast?
MegaETH produces small mini-blocks roughly every ten milliseconds through a single high-performance sequencer, then bundles them for settlement, and it publishes data to EigenDA to keep costs down.
What is the trade-off of a single sequencer?
A single high-performance sequencer allows very low latency but is a point of centralization, since one operator orders transactions. Reducing this is a known area the project works on, as with other rollups in their current stage.
Is MegaETH EVM compatible?
Yes. MegaETH runs an EVM-compatible execution environment, so existing Ethereum smart contracts and developer tooling work on it with little or no modification.
Can I hold MEGA in Zypto App?
Not yet. MEGA isn't in Zypto App at the moment. You can hold it in any self-custodial wallet, and you can ask us to add MegaETH using the "Request MegaETH" button above.
