Why SecondaryDAO Uses Arbitrum One
SecondaryDAO runs on Arbitrum One — a specialized Layer 2 blockchain built for applications that need ultra-low transaction costs. Here's everything you need to know about why we chose One and what it means for you as an investor.
What is Arbitrum One?
Arbitrum One is one of two main Arbitrum chains (the other being Arbitrum One). While both are Layer 2 solutions that scale Ethereum, they're optimized for different use cases:
• Arbitrum One: Optimized for DeFi and high-value transactions
• Arbitrum One: Optimized for high-volume, low-cost transactions (like gaming and social apps)
SecondaryDAO chose One because tokenized real estate involves frequent small transactions — buying tokens, receiving rent distributions, trading on secondary markets — and One's fee structure makes all of these affordable.

Why One is Perfect for Real Estate Tokens
Ultra-Low Transaction Fees
On One, typical transactions cost fractions of a cent. This means you can buy a single property token, receive monthly rent distributions, and trade on the secondary market without worrying about gas fees eating into your returns.
Fast Confirmations
Transactions on One confirm in seconds, not minutes. When you place an order or receive a distribution, you'll see it almost instantly.
Ethereum Security
Despite being a Layer 2, One inherits security from Ethereum's mainnet. Your tokens and transactions are protected by Ethereum's robust validator network.
Full ERC-20 Compatibility
All SecondaryDAO property tokens are standard ERC-20 tokens. They work with any Ethereum-compatible wallet and can be verified on arb1.arbiscan.io or explorer.secondarydao.com.
How One Works (The Technical Stuff)
One uses a technology called "AnyTrust" — a variant of optimistic rollups that's designed for even lower costs:
-
Transactions are processed off-chain by One's network
-
Data availability is managed by a committee of trusted parties
-
Final settlement happens on Ethereum, giving you L1 security guarantees
This architecture lets One achieve fees that are 10-100x lower than Arbitrum One, while still maintaining strong security guarantees.
Comparing the Options
Why not Ethereum Mainnet?
Gas fees on Ethereum can be $5-50+ per transaction. That's fine for large DeFi trades, but impractical for buying $100 worth of property tokens.
Why not other L2s?
We evaluated Polygon, Optimism, Base, and others. One offered the best combination of low fees, Ethereum security, and ecosystem support for our use case.
Getting Started on One
-
Add Arbitrum One to MetaMask (see our MetaMask Setup Guide)
-
Bridge ETH to One for gas fees (usually $1-2 is plenty for months of activity)
-
Bridge or acquire USDC on One for property purchases
-
Start investing in tokenized real estate!
Verifying Transactions
All SecondaryDAO transactions are public and verifiable. You can view any transaction, token contract, or wallet on One's block explorer:
Block Explorer: https://arb1.arbiscan.io or https://explorer.secondarydao.com
Just paste any transaction hash, contract address, or wallet address to see full details.
