Methodology Report a correction

Glossary Chain ID How wallet and RPC software identify a mainnet network. Glossary RPC endpoint What an RPC URL does and why public endpoints can be rate-limited. Glossary Mainnet The production network context for reviewed chain settings. Gas token ROSE gas token Other reviewed mainnet rows that use ROSE for gas. Guide Chain ID list Reviewed chain IDs, RPC URLs, explorers, and source links across Main.net.

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":[]}' \

Safety note

Oasis documentation warns that public RPC endpoints are points of trust and may be rate-limited, censored, or man-in-the-middle targets. Run dedicated infrastructure for sensitive use.

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