# Public RPC endpoints and chain IDs

HTTPS and WSS RPC endpoints for 134 networks on 94 chains, with chain IDs for mainnets and testnets. 27 networks have a keyless public endpoint ("No key"). For the others, put a Dwellir API key in place of `<key>`. The free plan gives 20 responses per second and 100,000 responses a day. Get a key at https://dashboard.dwellir.com/register. The same data as JSON: https://www.dwellir.com/public-rpc-endpoints.json

## Frequently asked questions

### Which networks have a public RPC endpoint with no API key?

27 networks on 17 chains have a keyless public endpoint: Acala, Asset Hub, Astar, Bridge Hub, Coretime, Enjin, Heima, Hydration, Karura, Kusama, Liberland, Paseo, People Kusama, People Westend, Polkadot, Shiden and XX Network. The table marks them "No key". Every other network needs a Dwellir API key.

### Is there a free RPC endpoint for Ethereum, Base or Polygon?

No. Dwellir has no keyless endpoint on any EVM network today. Ethereum, Base and Polygon need an API key. The free plan gives you 20 responses per second and 100,000 responses a day. Replace `<key>` in the endpoint URL with your key.

### What are the chain IDs of the most used EVM networks?

Ethereum: 1, sepolia 11155111. Base: 8453, sepolia 84532. Arbitrum: one 42161, sepolia 421614. Optimism: 10, sepolia testnet 11155420. Polygon: 137, amoy 80002. Binance Smart Chain: 56, testnet 97. Avalanche: 43114. Linea: 59144. Monad: 143, testnet 10143. Robinhood: 4663. The table lists the chain ID for every network that has one, including testnets.

### How do I check the chain ID of an RPC endpoint?

Call `eth_chainId`. It returns the chain ID in hex, so Base returns `0x2105` (8453) and Ethereum returns `0x1`. Wallets and libraries such as viem and ethers compare this value with the chain ID you configured and refuse to sign for the wrong chain.

### Why do some networks have no chain ID?

EIP-155 chain IDs belong to EVM networks, including EVM parachains such as Moonbeam and Astar. Polkadot, Kusama, Sui and TRON identify their networks in other ways, such as a genesis hash. A dash means the network has no EVM chain ID, or our catalog does not list it yet. To check an EVM endpoint, call `eth_chainId`.

### Should I use a public endpoint in production?

Everyone shares the keyless endpoints, so nobody gets reserved throughput on them. Use them for testing and light reads. For production traffic, use an API key, which gives you your own plan's rate limit.

### What is the difference between the HTTPS and WSS endpoints?

HTTPS sends one JSON-RPC request and gets one response. WSS keeps a WebSocket open, which you need for subscriptions such as `eth_subscribe` to new blocks or logs. Both use the same API key. A dash in the WSS column means the endpoint has no WebSocket URL.

### What does "Archive" mean in the table?

Archive nodes serve the endpoint, so it answers state queries at any past block. For example, `eth_getBalance` works at an old block number.

### What does eip155:8453 mean?

It is the CAIP-2 identifier for Base. `eip155` is the namespace for EVM chains, and 8453 is the chain ID. WalletConnect and MetaMask use this format to tell a dapp which chain a wallet is on.
