About Mainstreet Finance
We are democratizing access to institutional-grade yield — bringing CME index box spreads on-chain for everyone.
Our Mission
Mainstreet Finance was founded on a simple but powerful idea: institutional yield strategies should not be reserved for hedge funds and Wall Street insiders. By bridging the gap between traditional finance and decentralized protocols, Mainstreet Finance enables anyone with a crypto wallet to access the same risk-adjusted returns that CME index box spreads have historically provided to sophisticated investors.
Through msUSD — our yield-bearing synthetic dollar — and msY — our primary yield strategy — we convert market-neutral, USD-denominated positions into accessible, transparent, and composable on-chain assets.
"Institutional yield for everyone" is not just a tagline — it is the founding philosophy of every product decision we make at Mainstreet Finance.
What We Build
Mainstreet Finance operates at the intersection of DeFi infrastructure and real-world financial instruments. Our core products are designed to be transparent, composable, and yield-optimized.
msUSD
A yield-bearing synthetic dollar that holds its peg while continuously accruing institutional-grade returns. Stake, hold, or deploy msUSD across DeFi.
msY Strategy
Main Street Yield — our flagship strategy converting CME index box spreads into transparent, market-neutral, on-chain yield. Currently delivering ~12% APY.
Transparency
Full on-chain proof of reserves, public strategy attestations, and real-time dashboards — because trust must be verifiable, not assumed.
DeFi Composability
msUSD and msY are built to integrate natively with lending protocols, DEXes, and yield aggregators across EVM-compatible chains.
How It Works
CME index box spreads are a well-established arbitrage strategy in traditional finance. They exploit mispricings between index options on the Chicago Mercantile Exchange, producing near risk-free USD-denominated returns that are largely uncorrelated with crypto market volatility.
Mainstreet Finance bridges these strategies on-chain by:
1. Capital Aggregation
Users deposit USDC or other stablecoins into the Mainstreet Finance protocol, minting msUSD at a 1:1 ratio.
2. Strategy Deployment
Aggregated capital is deployed into CME index box spread positions managed by the msY vault strategy.
3. Yield Distribution
Generated yield is distributed proportionally to msUSD holders, with full on-chain accounting and transparency.
Protocol at a Glance
Mainstreet Finance has grown rapidly since launch, with over $46M in msUSD supply and a loyal community of yield-seekers.
Technology & Security
Mainstreet Finance is built on audited smart contracts deployed across EVM-compatible chains. Our architecture separates concerns between the msUSD token layer, the strategy vault layer, and the bridge layer — ensuring each component can be independently verified and upgraded through governance.
Security is a core priority. Our smart contracts have undergone third-party audits, and our proof-of-reserve system provides continuous on-chain attestation of the protocol's backing ratio. All strategy parameters and risk controls are transparent and accessible via our public documentation on Gitbook.
Smart Contract Audits
Core protocol contracts audited by independent third-party security researchers prior to mainnet deployment.
Proof of Reserves
On-chain reserve attestations ensure msUSD is always fully backed, with real-time verification available to all users.
Open Source
Protocol contracts are open source and available on GitHub, enabling community review and independent verification.
