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:

  1. Go to metamask.io and download the browser extension

  2. Create a new wallet or import an existing one

  3. 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:

  1. Open MetaMask and click the network dropdown at the top

  2. Click "Add network" then "Add a network manually"

  3. 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

  1. 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:

  1. Copy the token contract address from the property page

  2. In MetaMask, click "Import tokens"

  3. Paste the contract address

  4. 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

Why Arbitrum One?

SecondaryDAO uses Arbitrum One because:

• Ultra-low fees — transactions cost fractions of a cent

• Fast confirmations — no waiting around

• Ethereum security — backed by Ethereum's robust validator network

• Perfect for frequent trading — buy and sell tokens without worrying about gas costs
