To use Fuse Network, you need a Web3 wallet configured with the correct network details. Any EVM-compatible wallet works — MetaMask is the most common starting point. Once connected, you can interact with dApps, send transactions, and deploy smart contracts on Fuse.

Add Fuse to MetaMask

MetaMask is a browser-extension wallet that supports any EVM-compatible network. The steps below walk you through adding Fuse Mainnet manually.
1

Open MetaMask and go to network settings

Click the network selector at the top of the MetaMask extension (it shows the currently active network, such as “Ethereum Mainnet”). Select Add network at the bottom of the list, then choose Add a network manually.
2

Enter the Fuse Mainnet details

Fill in the fields using the values from the mainnet table above:
  • Network name: Fuse Network
  • New RPC URL: https://rpc.fuse.io/
  • Chain ID: 122
  • Currency symbol: FUSE
  • Block explorer URL: https://explorer.fuse.io/
3

Save and switch

Click Save. MetaMask will automatically switch to Fuse Network. The network selector at the top of the extension will now show “Fuse Network”.
4

Verify the connection

Your FUSE balance will appear in the main account view once you are on Fuse Network. If you are new to the network, the balance will show 0 FUSE until you bridge or transfer funds.
You can also add Fuse Network in one click via Chainlist — search for “Fuse” and click Add to MetaMask.

Add other wallets

The process is the same for any EVM wallet that supports custom networks (such as Trust Wallet, Rabby, or Coinbase Wallet). Enter the network name, RPC URL, Chain ID, symbol, and explorer URL from the table above. Some wallets require fewer fields.

Add the Spark Testnet

To add the Spark Testnet, repeat the MetaMask steps above using the testnet values: RPC https://rpc.fusespark.io/, Chain ID 123.

Get test FUSE from a faucet

Test FUSE is required to pay gas fees on Spark Testnet. Use one of the public faucets below:

ChainDrop

Request test FUSE directly from the ChainDrop faucet by connecting your wallet.

Stakely

Request test FUSE from the Stakely faucet. Requires a small on-chain balance on another network to prevent abuse.
Faucets impose rate limits. If a request fails, wait a few minutes before trying again or try the other faucet.
