Setting Up MetaMask for Arbitrum One
Ready to buy tokenized real estate on SecondaryDAO? First, you'll need to set up your MetaMask wallet to work with Arbitrum One — our blockchain network of choice for fast, low-cost transactions.
Step 1: Install MetaMask
If you don't have MetaMask yet:
-
Go to metamask.io and download the browser extension
-
Create a new wallet or import an existing one
-
Secure your seed phrase — never share it with anyone!
Step 2: Add Arbitrum One Network
MetaMask doesn't include Arbitrum One by default, so you'll need to add it manually:
-
Open MetaMask and click the network dropdown at the top
-
Click "Add network" then "Add a network manually"
-
Enter these settings exactly:
Network Name: Arbitrum One
RPC URL: https://arb1.arbitrum.io/rpc
Chain ID: 42161
Currency Symbol: ETH
Block Explorer URL: https://arb1.arbiscan.io/rpc
- Click "Save" — you're connected!
Step 3: Get ETH for Gas Fees
You'll need a small amount of ETH on Arbitrum One to pay for transaction fees (usually less than $0.01 per transaction — that's the beauty of One!).
Options to get ETH on One:
• Bridge from Ethereum mainnet using the Arbitrum Bridge
• Transfer from a centralized exchange that supports Arbitrum One
• Use a cross-chain bridge like Orbiter Finance
Step 4: Get USDC for Token Purchases
SecondaryDAO uses USDC for all property token purchases. You can:
• Bridge USDC from Ethereum to Arbitrum One
• Buy USDC directly if your exchange supports One withdrawals
Step 5: Import Property Tokens (Optional)
After purchasing property tokens, they'll appear automatically in your SecondaryDAO dashboard. To see them in MetaMask:
-
Copy the token contract address from the property page
-
In MetaMask, click "Import tokens"
-
Paste the contract address
-
Confirm the import
Helpful Tips
• Always double-check the network — make sure you're on "Arbitrum One" before transacting
• Bookmark https://explorer.secondarydao.com to verify your transactions
• Keep some ETH in your wallet for gas — a few dollars worth lasts a long time on One
• Never share your seed phrase or private keys with anyone
