Ethereum chain ID 1 and mainnet RPC URL

Reviewed

Checked June 26, 2026. Ethereum Mainnet is the primary public Ethereum production blockchain. Ethereum.org defines the network, while the listed RPC is a third-party public endpoint.

Ethereum RPC status and chain ID answer

Ethereum mainnet uses chain ID 1 / 0x1, RPC URL https://ethereum-rpc.publicnode.com, explorer https://etherscan.io, and ETH as the gas token. Use the latest source check and linked docs to verify the fields before adding the network to a wallet, script, or app.

Good fit when you need:
  • the Ethereum chain ID, RPC URL, explorer, and gas token in one place;
  • source documentation links beside the copied setup fields;
  • manual wallet config fields without connecting a wallet or choosing an RPC provider.
Before you paste these fields:
  • compare the chain ID against the source link on this page;
  • open the explorer once and confirm it matches the network you expect;
  • use the public RPC for setup checks, then choose monitored infrastructure for production traffic.

MethodologyReport a correction

Ethereum wallet-add fields

Wallet directory sites often expose a connect button. Main.net keeps the same MetaMask and EIP-3085 setup fields as text so developers can compare them with official/source docs before calling wallet_addEthereumChain.

curl eth_chainId check

Minimal JSON-RPC identity check. This verifies the endpoint-reported chain ID only, not uptime or production suitability.

curl -s -X POST \
  -H 'content-type: application/json' \
  --data '{"jsonrpc":"2.0","id":1,"method":"eth_chainId","params":[]}' \
  https://ethereum-rpc.publicnode.com

# Expected chain ID: 1 / 0x1

Developer signals

External dashboards a developer may inspect before choosing where to deploy. Main.net links to these references but does not collect the metric values, normalize methodologies, rank chains, or recommend deployments.

Safety note

Ethereum.org does not publish a canonical free public RPC for production use. Treat public endpoints as setup references and use dedicated infrastructure for apps.

Main.net is an independent reference site. It does not operate this chain, custody assets, execute transactions, or provide investment advice.
