The Mode chain ID is 34443 (0x868b in hex). Mode is an OP Stack Layer 2 on Ethereum. 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.
Mode Network Details for MetaMask
| Field | Value |
|---|---|
| Network name | Mode |
| RPC URL | https://mode.drpc.org |
| Chain ID | 34443 |
| Currency symbol | ETH |
| Block explorer | https://explorer.mode.network |
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.
Mode RPC URLs (Tested October 27, 2026)
| RPC endpoint | Returned chain ID | Response time |
|---|---|---|
https://mode.drpc.org | 34443 | 264 ms |
https://mainnet.mode.network | 34443 | 430 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 34443. The latest block was 46,472,346. Public endpoints are free and rate limited: for an app or a bot, use a paid provider or your own node.
How to Add Mode to MetaMask
- Click Add Mode to MetaMask above, or open MetaMask and go to Networks → Add a custom network.
- Enter the network name Mode, RPC URL
https://mode.drpc.organd chain ID 34443. - Set the currency symbol to ETH and the block explorer to https://explorer.mode.network.
- Save and switch to the new network. Your 0x address is the same as on other EVM networks.
Tip: Mode is part of the Optimism Superchain, so your 0x address is the same on Mode, OP Mainnet and Base.
