Bridge to Arbitrum One
To buy property tokens on SecondaryDAO, you'll need ETH (for gas fees) and USDC (for purchases) on Arbitrum One. This guide walks you through the different ways to get your funds onto Arbitrum One.
What You'll Need
Before bridging, make sure you have:
-
A wallet with ETH on Ethereum mainnet (for gas fees on both sides)
-
The tokens you want to bridge (ETH and/or USDC)
-
MetaMask set up with Arbitrum One (see our MetaMask Setup Guide)
Option 1: Official Arbitrum Bridge (Recommended)
The safest way to bridge is through the official Arbitrum bridge.
Step 1: Go to https://bridge.arbitrum.io
Step 2: Connect your wallet
Step 3: Select "Arbitrum One" as the destination network
Step 4: Choose the token you want to bridge (ETH or USDC)
Step 5: Enter the amount
Step 6: Click "Move funds to Arbitrum One"
Step 7: Confirm the transaction in your wallet
Important: The official bridge takes about 10-15 minutes for deposits. Withdrawals back to Ethereum take 7 days due to the challenge period.
Option 2: Third-Party Bridges (Faster)
For faster transfers, you can use cross-chain bridges. These are typically instant but charge small fees.
Popular options:
-
Orbiter Finance (orbiter.finance) — Fast and low fees
-
Hop Protocol (hop.exchange) — Supports ETH and USDC
-
Across Protocol (across.to) — Good for larger amounts
When using third-party bridges:
-
Select Ethereum as the source chain
-
Select Arbitrum One as the destination chain
-
Make sure you're bridging to Arbitrum One (Chain ID 42161)
Option 3: CEX Withdrawal (Easiest)
Many centralized exchanges support direct withdrawals to Arbitrum One. This is often the simplest and most cost-effective method.
Exchanges supporting Arbitrum One withdrawals:
-
Coinbase

Binance
-
Kraken

-
And many others
Simply select "Arbitrum One" as the withdrawal network when sending ETH or USDC from your exchange.
