net_peerCount

net_peerCount returns how many peers a Base node is currently connected to, encoded as a hex integer (for example "0x1a" is 26 peers). Base is Coinbase's OP Stack optimistic rollup that settles to Ethereum with gas paid in ETH, and a node leans on its peer set to receive newly sequenced blocks and gossip transactions; a healthy peer count is what keeps it in step with the ~2-second block cadence. Query it at https://base.therpc.io/YOUR_API_KEY on chain ID 8453 (hex 0x2105) and decode the hex to a decimal count.

Use cases

• Track peer count in a Base infrastructure dashboard to watch each node's network health over time and alert when connectivity drops.
• Detect an isolated Base node before it falls behind — a peer count near zero means it may stop receiving sequenced blocks and drift behind the ~2-second head.

Errors & troubleshooting

Common pitfalls

• A managed endpoint like https://base.therpc.io/YOUR_API_KEY returns the peer count of whichever backend Base node served your request, not a number tied to your account or session — so the value reflects the provider's infrastructure, not yours.
• A low peer count on a managed Base node does not necessarily mean your RPC calls are degraded; the provider's nodes stay in sync through their own internal links, so judge service health by response correctness and latency rather than this number alone.
