02Key Product Features

01
Fixed Monthly Payments

$1,120.64 fixed for the entire term regardless of Bitcoin price movements. The borrower's obligation never changes — whether Bitcoin goes to $200,000 or $20,000.

02
Dedicated Segregated Wallet

Each loan's Bitcoin collateral is held in a dedicated, segregated wallet. Collateral is never pooled or commingled with other borrowers' assets.

03
Voluntary Liquidation Option

Customer may request early exit at any time. Lender sells the minimum BTC needed to cover the remaining balance and yield maintenance fee. Surplus BTC is transferred to the customer's personal wallet.

The customer receives BTC, not cash.

04
Non-Recourse Structure

The lender will never pursue a deficiency judgment, engage debt collectors, or initiate legal proceedings against the borrower.

Default consequences are limited to three outcomes: (1) loss of BTC collateral, (2) credit bureau reporting, (3) permanent program exclusion.

03Yield Maintenance Formula

Yield Maintenance Calculation
YM Fee = PV of remaining interest payments × (Loan Rate − Treasury Rate) / Loan Rate

When Yield Maintenance Applies

ScenarioYM Applied?Rationale
Customer exits early, Bitcoin UP Yes Customer is profitable — fee is the price of the prepayment option
Customer exits early, Bitcoin FLAT Yes, if proceeds cover it Applied only to extent covered by collateral
Customer exits early, Bitcoin DOWN No Waived — collateral loss is sufficient
Customer defaults (stops paying) No Lender retakes Bitcoin, reports shortfall

Yield maintenance is ONLY applied when the customer is profitable. It is waived on underwater exits. This makes it legally defensible and non-predatory.

04Detailed Scenarios

All scenarios assume a $70,000 loan at 15% APR with a Treasury discount rate of 4.5%.

Scenario A — Bitcoin Moons

Exit Month 24 • BTC = $200,000

Bitcoin Value
$200,000
Remaining Principal
$63,100
YM Fee
$39,800
Total Settlement
$102,900
Surplus to Customer (in BTC)
~$97,100
Customer Invested to Date
$26,881

Lender outcome: Collects $39,800 yield maintenance + $63,100 principal. Capital redeploys immediately into new originations.

Scenario B — Bitcoin Flat

Full Term 120 months • BTC ≈ $70,000

Bitcoin Value at 120mo
~$70,000
Total Payments
$134,477
YM Fee
None (ran to term)
BTC to Customer
Full 1 BTC transferred

Lender outcome: Collected $64,477 in interest over 10 years. Steady, predictable return at the contractual 15% APR.

Scenario C — Bitcoin Crashes

Exit Month 24 • BTC = $20,000

BTC Liquidated
$20,000
Prior Payments
$26,881
Total Recovery
$46,881
YM Fee
WAIVED (underwater)
Shortfall
$43,100 reported to bureaus
Legal Action
None (non-recourse)
Program Access
Permanently revoked

Lender outcome: Loss of approximately $23,119. No legal action taken. Shortfall reported to credit bureaus. Borrower permanently excluded from program.

Scenario D — Bitcoin Moons, Customer Holds Longer

Exit Month 60 • BTC = $150,000

Bitcoin Value
$150,000
Remaining Principal
$48,600
YM Fee
$21,000
Total Settlement
$69,600
Surplus to Customer (in BTC)
~$80,400
Payments to Date
$67,238

Lender outcome: Collects $21,000 yield maintenance + $48,600 principal. Capital redeploys into new originations.

05Capital Velocity

The following table demonstrates how yield maintenance protects lender returns across all exit timelines. Earlier exits generate dramatically higher annualized returns due to yield maintenance acceleration.

Exit MonthRemaining BalanceYM FeeTotal CollectedAnnualized Return
Month 6 $68,450 $47,800 $116,250 ~95%
Month 12 $66,800 $45,200 $112,000 ~60%
Month 24 $63,100 $39,800 $102,900 ~32%
Month 36 $58,900 $33,900 $92,800 ~24%
Month 60 $48,600 $21,000 $69,600 ~15%
Month 120 $0 $0 $134,477 ~15%

Based on $70,000 at 15% APR. Treasury 4.5%.

Annualized return NEVER falls below ~15% regardless of exit timing. Early exits generate dramatically higher annualized returns due to yield maintenance acceleration. The lender's downside is the contractual rate; the upside is uncapped through capital velocity.

06Legal Defensibility

Yield maintenance is a well-established prepayment mechanism with decades of commercial lending precedent. The following five arguments establish its defensibility in the context of Bitcoin installment finance.

01
Not a Penalty

7th Circuit precedent establishes that yield maintenance is not a penalty because the borrower is exercising a contractual right, not committing a breach. Prepayment is voluntary — the fee is the agreed-upon cost of that option.

02
Asymmetric Optionality

The borrower holds a put option: walk away, surrender collateral, incur no personal liability. Yield maintenance is the lender's compensation for granting that valuable non-recourse right.

03
Waived on Underwater Exits

The fee only applies when the borrower profits from the transaction. If Bitcoin has declined and the exit is underwater, yield maintenance is fully waived. This asymmetry cannot be characterized as predatory.

04
Full Disclosure

Plain-language explanation of yield maintenance provided at origination. Separate acknowledgment signature required. Pre-calculated 6-month yield maintenance schedule delivered to borrower before closing.

05
Commercial Precedent

Yield maintenance is standard in CMBS, Fannie Mae, and Freddie Mac commercial loan products. The mechanism is novel for Bitcoin but the legal and financial framework is well-established.

07Summary

Key Takeaways

The loan product combines borrower-friendly protections (fixed payments, non-recourse, segregated custody) with lender-optimized economics (yield maintenance, capital velocity, collateral-backed). This creates a product that is both commercially attractive and regulatorily sound.
