Telos EVM chain ID 40 and mainnet RPC URL

Source snapshot

Source evidence snapshot July 4, 2026. Telos documentation lists Telos Mainnet RPC URL, chain ID 40, TLOS as the symbol, and Teloscan as the explorer.

Telos EVM RPC status and chain ID answer

Telos EVM mainnet uses chain ID 40 / 0x28, RPC URL https://rpc.telos.net, explorer https://www.teloscan.io, and TLOS 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 Telos EVM 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.

Verification record

Automated source snapshots and recorded probe evidence are tracked separately. The source snapshot timestamp is not a manual review date. This is not a live uptime, latency, or production reliability monitor. If a recorded public RPC probe fails, verify the source links and current endpoint availability before changing production configuration.

Telos EVM 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.

Monitoring evidence

These checks are review signals only. They are not uptime, latency, privacy, or production reliability claims. A source fetch failure or eth_chainId failure can mean a source page or public RPC endpoint was unavailable, changed, or rate-limited during a check. Re-open source links and test current RPC availability before relying on a public endpoint.

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://rpc.telos.net

# Expected chain ID: 40 / 0x28

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

Telos documentation notes an EVM 2.0 upgrade period. Confirm the current RPC and explorer against Telos docs before routing production traffic.

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