Copy Base chain ID and RPC URL

Base mainnet uses chain ID 8453 / 0x2105, ETH as the gas token, the public RPC endpoint https://mainnet.base.org, and explorerhttps://base.blockscout.com. Use this guide to copy the fields, open Base docs, and check setup cautions before use. Build generated Jul 20, 2026, 4:21 PM UTC; the source evidence snapshot is labeled July 4, 2026. If the public RPC returns an intermittent error, recheck Base docs and current endpoint availability before changing app config.

  • Base chain ID 8453 / 0x2105 for wallet or RPC setup;
  • the public RPC URL, explorer, ETH gas token, and Base docs together;
  • wallet config text without connecting a wallet or assuming RPC uptime.

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.

Important note

Base states its public endpoints are rate-limited and not for production systems. Production apps should use a node provider or run dedicated infrastructure.

Main.net is an independent reference site and is not affiliated with Coinbase or Base. Always verify important details in the source documentation before moving funds.

Treat the public RPC endpoint as a setup reference, not as a production reliability promise. Teams running apps on Base should compare monitored provider endpoints, request limits, archive access, alerting, and fallback behavior before shipping user-facing flows. Crypto.club has a shortBase public endpoint vs provider checklistfor that decision.

Use the status page copy path for the current reviewed config:/status/base/#copy-ready-config.
