Built for BOB
Bitcoin-DeFi, BTC-backed assets, and cross-ecosystem apps on BOB. Every request routes to the nearest healthy node, with automatic failover and no per-request throttling — the gaps public endpoints leave.
Low-latency BOB RPC — 2 regions, geo-routed
We run our own bare-metal BOB nodes in 2 regions across US-East, US-West, EU and Asia — not a reseller of Alchemy or Infura. Every request is geo-routed to the region you call from: the gateway reads the Cloudflare edge location and picks the nearest healthy node, with automatic failover. A trading bot in Singapore hits our Singapore BOB node, not one in the US — real round-trip time saved on your hot path.
BOB RPC — FAQ
What is BOB's chain ID?
BOB's chain ID is 60808 (hex 0xed88). Its native currency is ETH and its block explorer is explorer.gobob.xyz. You can connect with NodeFlare's free public RPC at https://rpc.nodeflare.app/bob/public — no API key required.
How do I add BOB to MetaMask?
In MetaMask, open the network menu → "Add a network" → "Add a network manually", then enter — Network name: BOB; New RPC URL: https://rpc.nodeflare.app/bob/public; Chain ID: 60808; Currency symbol: ETH; Block explorer URL: https://explorer.gobob.xyz. Save, then switch to BOB. The endpoint is free and needs no account.
What is the BOB RPC URL?
NodeFlare's public BOB RPC URL is https://rpc.nodeflare.app/bob/public over HTTPS. No API key is required for the public endpoint.
Is the BOB RPC free?
Yes. The public BOB endpoint is free with no sign-up. A free API key unlocks higher rate limits, heavy methods, and a dedicated path — 2,000,000 compute units per month, no credit card.
What are the BOB RPC rate limits?
The public endpoint is limited to 2 requests/second per IP. A free key gives 10 requests/second; paid plans scale to 500 req/s. Every plan includes all 22 supported chains.
Is NodeFlare a good BOB RPC provider?
NodeFlare is an independent BOB RPC provider that runs its own nodes — not a reseller or aggregator of third-party backends. The public endpoint is free with no sign-up; a free API key adds higher rate limits, and heavy methods (eth_getLogs, trace_*, debug_*) — 2,000,000 compute units per month, no credit card.
Is there a dedicated BOB RPC node?
Yes. NodeFlare runs its own dedicated BOB node(s), and every request is routed to the nearest healthy node with automatic failover. A free or paid key gives you a dedicated endpoint path with your own rate limits and full access to archive methods like eth_getLogs and debug_traceTransaction.
