The Self-Repaying Mortgage (SRM) is a revolutionary financial product built for the Bitcoin era. It allows you to purchase or refinance a home by using Bitcoin, Gold, or Silver as 1:1 collateral. By leveraging your Bitcoin, Gold, or Silver as pristine collateral the SRM enables you to borrow against your assets while keeping your savings intact.
The Core Mechanics: 1:1 Collateral
Unlike traditional mortgages that rely on debt-to-income ratios and credit scores, the SRM is an asset-based loan. To initiate an SRM, borrowers post 1:1 collateral (100% LTV) in Bitcoin, Gold, or Silver. This Collateral is held in a bankruptcy-remote Special Purpose Vehicle (SPV) by our strategic partner, BitGo.
Key Strategic Advantages:
- Your Sound Money Collateris Your Credit Score: No credit checks, no income verification, and no W2 documentation are required. Your savings speak for themselves.
- Zero Liquidation Risk: Because the loan is dual-collateralized by both the property title and the collateral there are no margin calls. As long as you maintain your monthly terms, your collateral is secure regardless of market volatility.
- No Rehypothecation: Your Bitcoin is never lent out or used for platform leverage. It remains verifiable on-chain at all times.
Variable Interest & The "Sound Money" Discount
The SRM features a variable interest rate that rewards you for the strength of your collateral position. your APR is determined by your PRN Loyalty Level and Collateral Ratio. The rate adjusts based on your average Loyalty Level and Collateral Ratio for that month.
| Collateral Ratio | Loan-to-Value (LTV) | Diamond Tier APR | Basic Tier APR |
|---|---|---|---|
| 300% | 33% | 3.00% | 6.00% |
| 200% | 50% | 5.00% | 8.00% |
| 100% | 100% | 7.00% | 10.00% |
As the price of your Collateral rises, your Collateral Ratio increases, which automatically lowers your interest rate. This creates a "virtuous cycle" where the appreciation of your asset makes your debt cheaper over time.
SRM vs. Traditional Mortgages
Traditional mortgages were designed for a world without high-growth digital assets. The SRM is built to outperform the legacy system in every metric.
| Metric | Traditional Mortgage | Self-Repaying Mortgage |
|---|---|---|
| Approval Hurdles | Hard credit pull, DTI, Tax returns | None |
| Typical Rate (30yr) | 5.5% – 7.5% (Fixed) | 3.0% – 10.0% (Variable/Loyalty) |
| Asset Appreciation | Home Equity only | Home Equity + 100% BTC Upside |
