The Gnosis Chain chain ID is 100 (0x64 in hex). Gnosis Chain, formerly xDai, is an EVM chain where gas is paid in xDAI, a bridged version of DAI, so fees are stable in dollar terms. 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.
Gnosis Chain Network Details for MetaMask
| Field | Value |
|---|---|
| Network name | Gnosis |
| RPC URL | https://rpc.gnosischain.com |
| Chain ID | 100 |
| Currency symbol | XDAI |
| Block explorer | https://gnosisscan.io |
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.
Gnosis Chain RPC URLs (Tested October 27, 2026)
| RPC endpoint | Returned chain ID | Response time |
|---|---|---|
https://rpc.gnosischain.com | 100 | 454 ms |
https://rpc.gnosis.gateway.fm | 100 | 404 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 100. The latest block was 48,970,991. Public endpoints are free and rate limited: for an app or a bot, use a paid provider or your own node.
How to Add Gnosis Chain to MetaMask
- Click Add Gnosis Chain to MetaMask above, or open MetaMask and go to Networks → Add a custom network.
- Enter the network name Gnosis, RPC URL
https://rpc.gnosischain.comand chain ID 100. - Set the currency symbol to XDAI and the block explorer to https://gnosisscan.io.
- Save and switch to the new network. Your 0x address is the same as on other EVM networks.
Tip: Gas on Gnosis is xDAI, not GNO. GNO is the staking token; you need a little xDAI to send transactions.
Gnosis Chiado Testnet
| Field | Value |
|---|---|
| Network name | Gnosis Chiado |
| RPC URL | https://gnosis-chiado.drpc.org |
| Chain ID | 10200 (0x27d8) |
| Currency symbol | XDAI |
| Block explorer | https://gnosis-chiado.blockscout.com |
Testnet tokens come from faucets and are worth nothing. Do not send real XDAI to a wallet connected to Gnosis Chiado.
How to Get XDAI on Gnosis Chain
The widget at the top of this page is set to swap into XDAI on Gnosis Chain: pick the token you have on another network, enter your address and sign once. Routes, fees and timing are covered in our Gnosis Chain bridge guide.
