Today we shipped the biggest expansion in NodeFlare's history: 16 new EVM chains, taking us from 7 to 23 networks — every one of them served from our own bare-metal nodes, with a free public endpoint and full support on the free tier.
The new lineup
| Chain | Chain ID | What it is |
|---|---|---|
| Unichain | 130 | Uniswap's DeFi-native L2, 1 s blocks |
| Sonic | 146 | Sub-second aBFT L1 from the former Fantom team |
| Polygon | 137 | The battle-tested PoS workhorse |
| Linea | 59144 | Consensys' zkEVM |
| Mantle | 5000 | Modular L2 with EigenDA |
| Zircuit | 48900 | zk-rollup with sequencer-level security |
| Robinhood Chain | 4663 | Tokenized real-world assets, ~250 ms blocks |
| XLayer | 196 | OKX's zkEVM |
| Soneium | 1868 | Sony's consumer L2 |
| Arbitrum Nova | 42170 | AnyTrust fees for gaming & social |
| BOB | 60808 | Bitcoin DeFi on the OP Stack — served from two regions |
| Ink | 57073 | Kraken's L2 (chain ID 0xdef1) |
| Cronos | 25 | Crypto.com's chain, instant finality |
| Mode | 34443 | DeFi-focused Superchain member |
| Sei | 1329 | Parallelized EVM, ~400 ms finality |
| Plasma | 9745 | Stablecoin-first L1 with PlasmaBFT |
They join Ethereum, Base, BNB Chain, Arbitrum One, OP Mainnet, HyperEVM and Avalanche.
Same endpoint pattern, every chain
Nothing about the integration changes — swap the chain slug and you're done:
https://rpc.nodeflare.app/{chain}/public # free, no API key
https://rpc.nodeflare.app/{chain}/v1/{YOUR_KEY} # free key: higher limits + heavy methodsOne free API key covers every chain we serve: 2,000,000 compute units/month, with eth_getLogs (75 CU) and trace_*/debug_* (100 CU) included — no credit card.
Our own nodes, not an aggregator
Every one of these chains runs on hardware we operate ourselves, across six regions, behind the same health-checked, geo-routed gateway as our original seven. When you hit rpc.nodeflare.app, you land on a NodeFlare node — never on one of dozens of anonymous third-party backends.
That matters most on the young chains: for networks like Robinhood Chain and Plasma we're among the first independent RPC providers anywhere, and for Unichain, Soneium, Ink, Zircuit and BOB the list of alternatives is still very short. If you're building there, you no longer depend on a single official endpoint.
Documentation for every method, on every chain
Each chain ships with a full per-method reference — parameters, compute-unit costs, runnable examples, and chain-specific notes (real measured block times, finality behaviour, gas-token quirks like Mantle's MNT or XLayer's OKB). No templated filler: an eth_getLogs on Sei page tells you different things than eth_getLogs on Arbitrum Nova, because the chains genuinely behave differently.
What's next
WebSocket subscriptions are currently live on our original seven chains; we're wiring newHeads streaming for the new networks chain by chain. Follow the changelog for updates.
