The Ink chain ID is 57073 (0xdef1 in hex). Ink is an OP Stack Layer 2 developed by Kraken. 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.
Ink Network Details for MetaMask
| Field | Value |
|---|---|
| Network name | Ink |
| RPC URL | https://rpc-qnd.inkonchain.com |
| Chain ID | 57073 |
| Currency symbol | ETH |
| Block explorer | https://explorer.inkonchain.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.
Ink RPC URLs (Tested October 27, 2026)

|---|---|---|
https://rpc-qnd.inkonchain.com | 57073 | 256 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 57073. The latest block was 59,613,879. Public endpoints are free and rate limited: for an app or a bot, use a paid provider or your own node.
How to Add Ink to MetaMask
- Click Add Ink to MetaMask above, or open MetaMask and go to Networks → Add a custom network.

https://rpc-qnd.inkonchain.comand chain ID 57073. - Set the currency symbol to ETH and the block explorer to https://explorer.inkonchain.com.
- Save and switch to the new network. Your 0x address is the same as on other EVM networks.
Tip: Ink is part of the Optimism Superchain, so your 0x address is the same as on OP Mainnet and Base. Check that the network says Ink before you send.
