Chain ID list

Need a mainnet chain ID? This list shows decimal IDs and hex IDs when available, plus RPC URL, explorer, gas token, and source docs for each reviewed network. Always verify the chain ID and RPC URL against source documentation before adding a network or signing transactions.

Answer first

Mainnet chain ID lookup answer

MegaETH uses chain ID 4326 / 0x10e6, Polygon PoS uses 137 / 0x89, OP Mainnet uses 10 / 0xa, and Avalanche C-Chain uses 43114 / 0xa86a. Use each status page for the matching RPC URL, explorer, gas token, and source links.

Wallet setup caution

A matching chain ID does not prove an RPC endpoint is official, safe, private, or reliable. Phishing sites can copy legitimate network values. Use the linked source page for each network when adding a custom wallet network or configuring production infrastructure.

Chain ID list FAQ

What is a chain ID list?
A chain ID list maps mainnet networks to decimal and hex chain IDs, RPC URLs, explorers, gas tokens, and source links.
What is MegaETH chain ID?
MegaETH mainnet uses chain ID 4326 / 0x10e6, RPC URL https://mainnet.megaeth.com/rpc, and explorer https://mega.etherscan.io.
Should I verify a chain ID before adding a wallet network?
