Can I Add Avalanche Fuji Testnet to MetaMask?

Yes, you can add the Avalanche Fuji testnet to MetaMask. To do this, enter the network name, RPC URL, chain ID, and symbol in MetaMask's custom network settings. 

Fuji serves as a test environment for deploying and testing Avalanche Layer 1 blockchains and Subnet-EVM virtual machines, making it an essential tool for developers.

How to Add Avalanche Fuji to MetaMask

Connecting Avalanche Fuji to MetaMask is straightforward, and using Chainlist simplifies the process. Chainlist aggregates verified EVM networks, ensuring you add the correct network settings without manual input.

Here’s how to add Avalanche Fuji to MetaMask:

1. Visit Chainlist: Open the Chainlist website and connect your MetaMask wallet.
2. Search for Avalanche Fuji: Use the search bar to find "Avalanche Fuji Testnet."
3. Add Network: Select Avalanche Fuji from the results and click "Add to MetaMask."
4. Confirm: Approve the addition in MetaMask to complete the setup.

Avalanche Fuji RPC and Network ID

To manually add the Avalanche Fuji testnet to MetaMask, use these settings found in Avalanche's official documentation for wallet setup:

• Network Name: Avalanche Fuji Testnet
• RPC URL: https://api.avax-test.network/ext/bc/c/rpc
• Chain ID: 43113
• Currency Symbol: AVAX
• Block Explorer URL: https://testnet.snowscan.xyz

Enter these details in MetaMask’s custom network settings to connect and access Fuji testnet services.

What is Avalanche Fuji?

Avalanche Fuji is Avalanche's testnet, designed for developers to build and test applications before mainnet deployment. It supports EVM-compatible C-Chain operations, including Solidity smart contracts and Ethereum-based tools.

Fuji enables testing of Subnet-EVM deployments, validator nodes, and custom Layer 1 blockchains, using test AVAX as currency. It replicates mainnet functionality for a smooth transition from testing to production.

Bottom Line

Adding Avalanche Fuji to MetaMask gives developers access to a testnet that mirrors mainnet functionality. 

By connecting through Chainlist or entering settings manually, developers can safely test and deploy blockchain applications before moving to production.
