On this page
Below are the public Avalanche C-Chain RPC endpoints listed on chainlist.org, re-checked every 5 minutes from our probe server and sorted by current latency. Failed endpoints are collapsed at the bottom.
Public RPCs are free and shared: expect rate limits, no SLA and weaker privacy. For production apps use a dedicated endpoint.

Latency: one eth_blockNumber request from our server every 5 minutes. Block: height reported by the endpoint; a minus shows how many blocks it lags behind the fastest one. Privacy: what the operator declares, from chainlist.org.

What is the chain ID of Avalanche C-Chain?
Avalanche C-Chain's chain ID is 43114 (hex 0xa86a). Wallets use it to tell Avalanche C-Chain apart from other networks and to prevent replaying transactions across chains.
Is there a free Avalanche C-Chain RPC?
Yes. We list 26 public Avalanche C-Chain endpoints; 13 answered at the last check. They are free but shared and rate-limited, with no uptime guarantee.
What currency does Avalanche C-Chain use for gas?
Avalanche (AVAX).
How do I add Avalanche C-Chain to MetaMask?
Use “Add to wallet” at the top of this page, or add the network manually with the values in the table under “How to add Avalanche C-Chain to MetaMask”.
HTTPS or WSS — which should I use?
HTTPS for regular requests such as reading balances or sending transactions; WSS keeps a connection open for subscriptions such as new blocks or logs.
Are public RPC endpoints safe?
A public endpoint cannot move your funds, but it can see your IP address and the requests you send. Check the Privacy column: it shows what each operator says it logs, from chainlist.org.
How often are endpoints checked?
Every 5 minutes. We send one eth_blockNumber request to each HTTPS endpoint and record the response time and block height. An endpoint is marked offline after 3 failed checks in a row.
Does any provider pay to be listed?
No. No provider pays to be listed or to change its place in the table; the order is by measured latency.
How to add Avalanche C-Chain to MetaMask
- Open MetaMask, open the network menu and choose “Add a custom network”.
- Copy each value from the table into the form.
- Save, then switch to the new network.
- If balances do not load, try another RPC URL from the list above.
- Network name
- RPC URL
- Chain ID
- Currency symbol
- Block explorer URL
