MegaETH chain ID 4326, mainnet RPC URL, and launch FAQ
MegaETH mainnet uses chain ID 4326, ETH as gas token, and
public RPC URL https://mainnet.megaeth.com/rpc in the source record Main.net tracks.
What Main.net tracks
MegaETH searches often mix three different intents: "what is MegaETH," "when is MegaETH mainnet," and "what chain ID or RPC URL should I use?" Main.net handles the third question directly and handles launch context only as a source record. The site does not assign launch stages, does not say whether a network is ready for deposits, and does not recommend tokens or applications.
The current MegaETH record points to official network connection and developer documentation. For exact chain metadata, use the MegaETH status page. For launch-source context, use the MegaETH source record.

What to expect before integrating
Treat early mainnet documentation as something to re-check before every production release. RPC endpoints can change, rate limits can apply, and wallets or SDKs may require chain ID confirmation before they sign transactions. Main.net keeps the source links visible so a developer can compare copied settings against the current documentation.
If you find a stale MegaETH source link, use the correction link on the status page and include a public source URL. Do not include private keys, credentials, or confidential deployment details in public reports.
