How to Add MegaETH to MetaMask

Can I Add MegaETH to MetaMask?

Yes, you can add MegaETH Testnet to MetaMask as a custom network. As an EVM-compatible Layer 2, it supports dApps, testnet ETH, and real-time execution with millisecond block times and 100,000 TPS.

The testnet is in its early phase, with rate-limited RPCs, potential rollbacks, and no token incentives. Despite this, it offers a high-speed testing ground for the highly anticipated L2.

About MegaETH

MegaETH is an Ethereum Layer 2 designed for real-time applications, using a centralized rotational sequencer to process transactions with millisecond latency and 100,000 TPS. Instead of traditional consensus, it applies direct state updates, eliminating re-execution delays. 

The architecture splits responsibilities across sequencers, replica nodes, and provers, ensuring efficient execution, validation, and data availability while maintaining Ethereum compatibility.

Final Thoughts

Adding MegaETH Testnet to MetaMask is simple, but be aware that RPC endpoints can change, and network maintenance may cause downtime or rollbacks. 

Always check for the latest updates to avoid disruptions when testing transactions or deploying contracts. Keeping up with testnet changes ensures a more reliable development experience.
