No project pays to be listed. How we test
On this page
Below are the public Blast 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 Blast?
Blast's chain ID is 81457 (hex 0x13e31). Wallets use it to tell Blast apart from other networks and to prevent replaying transactions across chains.
Is there a free Blast RPC?
Yes. We list 25 public Blast endpoints; 11 answered at the last check. They are free but shared and rate-limited, with no uptime guarantee.
What currency does Blast use for gas?
Ether (ETH).
How do I add Blast 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 Blast 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 Blast 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
