How to Add MegaETH to MetaMask (Mainnet & Testnet)

Summary: Adding MegaETH to your MetaMask wallet is a simple process that takes under 3 minutes and requires basic configuration using the official mainnet RPC details.
The most efficient method involves using Chainlist for automatic integration, ensuring a secure and accurate connection to the high-performance MegaETH network with minimal effort.
ChainList is the most trusted aggregator of EVM-based Layer 1 and 2 networks. It allows users to instantly connect their MetaMask to verified Chain and Network IDs, ensuring a safe connection.

Can I Add MegaETH to MetaMask?
Yes, you can add MegaETH to MetaMask by importing its network details, since MegaETH is EVM-compatible and works like other custom Ethereum Layer 2 networks.
The most common method is using Chainlist: connect MetaMask, search “MegaETH,” then click Add to Wallet to populate RPC and Chain ID.
Common mistakes include pasting an outdated RPC URL, picking the wrong network (Mainnet vs Testnet), or entering the Chain ID incorrectly. Also watch for fake “Add network” pop-ups and only approve changes on trusted sites and official docs.
How to Add MegaETH to MetaMask
Adding MegaETH takes under a minute if you use Chainlist, which automatically fills MetaMask with the correct RPC, Chain ID, and explorer.
Follow these simple steps to add MegaETH to your MetaMask:
- Open Chainlist: visit ChainList, verify the domain in your browser, then connect MetaMask using the top-right Connect button.
- Search MegaETH: use the search bar, select MegaETH Mainnet or MegaETH Testnet, and double-check the listed Chain ID.
- Add chain: click Add to Wallet, approve the network request in MetaMask, and let Chainlist autofill RPC URL and explorer.
- Switch networks: in MetaMask’s network dropdown, choose MegaETH, confirm the name matches your target environment, then save changes.
After you’ve added MegaETH once, MetaMask may auto-detect the network when a dApp prompts a switch, but always review all parameters first.

MegaETH Mainnet RPC and Chain ID
Use these official MegaETH Mainnet settings in MetaMask.
- Network Name: MegaETH Mainnet
- RPC URL: https://mainnet.megaeth.com/rpc
- Chain ID: 4326
- Currency Symbol: ETH
- Block Explorer: https://mega.etherscan.io
Before adding the network, confirm the latest RPC settings in MegaETH’s official documentation to ensure accuracy and maintain a secure connection to the live network.
MegaETH Testnet RPC and Chain ID
Configure your MetaMask using these MegaETH testnet details.
- Network Name: MegaETH Testnet
- RPC URL: https://carrot.megaeth.com/rpc
- Chain ID: 6343
- Currency Symbol: ETH
- Block Explorer: https://megaeth-testnet-v2.blockscout.com
What Assets Does MegaETH Support?
MegaETH supports standard Ethereum-style assets, including native ETH for gas and common token standards like ERC-20 and ERC-721. On mainnet you’ll also see bridged and ecosystem tokens, such as MEGA, USDm (MegaETH's native stablecoin), and wrapped ETH variants in supported dApps.
If a token doesn’t appear automatically, import it by contract address from an official token list or explorer. For testnet, faucets and apps may issue mock tokens, which are separate from mainnet assets and carry no value.

Is Adding MegaETH to MetaMask Safe?
Adding MegaETH is generally safe when you use verified network details and trusted tools like Chainlist or the official MegaETH documentation. MetaMask simply stores RPC and Chain ID settings; it doesn’t “install” any software on your device.
The bigger risk is phishing: malicious sites can trick you into adding look-alike networks or approving harmful token spend. Always compare the Chain ID and explorer URL to official sources, and consider using a hardware wallet for large balances.
About MegaETH
MegaETH is an EVM-compatible network focused on “real-time Ethereum,” aiming for extremely low latency and high throughput. Its design streams transactions continuously, targeting sub-10ms block times while ultimately settling on Ethereum for security guarantees and finality.
MegaETH provides public RPC endpoints for both mainnet and testnet, plus a performance dashboard and explorers to inspect activity. Because it uses MegaEVM and a different gas model, some tools can misestimate gas unless configured properly.
The ecosystem includes canonical bridging from Ethereum, predeployed OP Stack contracts, and a growing set of DeFi and tooling integrations.

Final Thoughts
Configuring MegaETH in your MetaMask wallet is a straightforward task that involves either manual input or using a quick automated tool like Chainlist.
Ensure you have the correct MegaETH RPC details for the mainnet or testnet to avoid any connectivity issues when sending your digital funds.
Once setup is complete, you can explore the MegaETH ecosystem, participate in testing, and interact with various high-performance decentralized applications built on this infrastructure.
Frequently asked questions
How do I get testnet ETH for MegaETH?
You can claim testnet tokens by visiting the official MegaETH Discord or dedicated web portals where users request small amounts of ETH for testing.
Can I bridge funds from Ethereum to MegaETH?
Yes, use the official bridge interface to move assets between layers, ensuring you follow the instructions to lock collateral on the source chain correctly.
What is the gas fee like on MegaETH?
Due to the high-performance architecture and optimized execution, gas fees are designed to be a fraction of a cent, making frequent transactions very affordable.
Why does MegaETH Testnet sometimes show a different Chain ID online?
Directories can lag behind updates. Use MegaETH’s docs as the source of truth and match the Chain ID shown on the official Testnet page.
