The Soneium chain ID is 1868 (0x74c in hex). Soneium is an OP Stack Layer 2 developed by Sony Block Solutions Labs. Gas is paid in ETH. Below are the exact settings MetaMask asks for, public RPC endpoints we tested on October 27, 2026, and a one-click button to add the network.
Soneium Network Details for MetaMask
| Field | Value |
|---|---|
| Network name | Soneium |
| RPC URL | https://rpc.soneium.org |
| Chain ID | 1868 |
| Currency symbol | ETH |
| Block explorer | https://soneium.blockscout.com |
Copy these values exactly. If the RPC URL returns a different chain ID than the one you enter, MetaMask stops with a chain ID mismatch warning: that usually means a typo or an RPC for another network.
Soneium RPC URLs (Tested October 27, 2026)
| RPC endpoint | Returned chain ID | Response time |
|---|---|---|
https://rpc.soneium.org | 1868 | 684 ms |
We sent eth_chainId and eth_blockNumber to each endpoint from Europe on October 27, 2026; the table lists only endpoints that answered with chain ID 1868. The latest block was 29,988,769. Public endpoints are free and rate limited: for an app or a bot, use a paid provider or your own node.
