How to Add Avalanche C-Chain to MetaMask

  1. Click Add Avalanche C-Chain to MetaMask above, or open MetaMask and go to Networks → Add a custom network.
  2. Enter the network name Avalanche C-Chain, RPC URL https://api.avax.network/ext/bc/C/rpc and chain ID 43114.
  3. Set the currency symbol to AVAX and the block explorer to https://snowscan.xyz.
  4. Save and switch to the new network. Your 0x address is the same as on other EVM networks.

Tip: Only the C-Chain can be added to MetaMask. The X-Chain and P-Chain use other address formats and need the Core wallet.
