Supported chains

Ethereum RPC →2 regions

Ethereum Mainnet (Chain ID 1). Use basic JSON-RPC methods without a key; log queries and other restricted methods require an API key and remain subject to plan limits.

https://rpc.nodeflare.app/eth/public

Base RPC →5 regions

Base Mainnet (Chain ID 8453) — Coinbase's Ethereum L2 built on the OP Stack. Low fees, high throughput, and full EVM compatibility.

https://rpc.nodeflare.app/base/public

BNB Chain RPC →4 regions

BNB Smart Chain (Chain ID 56) — high-throughput EVM chain with fast block times and low transaction costs. Formerly Binance Smart Chain.

https://rpc.nodeflare.app/bnb/public

Arbitrum One RPC →5 regions

Arbitrum One (Chain ID 42161) — Ethereum's leading optimistic rollup. Low fees, fast finality, and full EVM equivalence.

All public endpoints support standard JSON-RPC 2.0 over HTTPS; WebSocket (WSS) is available on Ethereum, Base, BNB Chain, Arbitrum, Optimism, HyperEVM and Avalanche. Without an API key: 1 request per 10 seconds per IP, with basic methods only. Heavy methods such as eth_getLogs, trace_* and debug_* require an API key and remain subject to plan and method limits.

Running this in production?

Public endpoints are shared and rate-limited. A free key gives you a dedicated path with higher limits, multi-region routing, and automatic failover — every chain included.
