Bitcoin Floor Bonds

The Problem

Every Bitcoin loan ever made has the same flaw.

They lend against spot price.

The borrower posts BTC. The lender values it at today's market price. If price drops, the borrower gets liquidated. The lending product punishes the people who are right about Bitcoin's long-term trajectory.

Floor Bonds fix this by lending against something else entirely: the floor's growth.

The Mechanism

The power law floor grows at approximately 38% per year. Paper 2 established this as the Bitcoin Floor Rate (BFR). It has never been breached. It is measurably strengthening.

A Floor Bond lets you borrow against that growth. Not against your Bitcoin's current value. Against how much the floor will grow in the next 12 months.

By Year 2, the floor's growth exceeds your borrowing need. The debt pays itself. No action required.

The loan-to-value ratio peaks at 47.2% in Year 4 — measured at floor prices, the most conservative valuation possible — and declines every year after. The liquidation price never approaches the floor.

Two Sides, Both Better Off

The borrower keeps their Bitcoin. Receives perpetual fiat income. No margin calls. No liquidation. The 38% floor growth is theirs. The debt disappears.

The lender earns a fixed coupon (3–5%) on the safest collateralised loan in crypto. Near-zero default risk. The collateral's floor value grows at 38% annually. Their position improves every day the loan is outstanding.

Traditional Bitcoin lenders charge 8–12% because they price in liquidation risk. Floor Bonds eliminate that risk. Both sides capture the value that was previously destroyed by the liquidation premium.

The New Carry Trade

For institutional lenders, the value is not the coupon. It's the risk profile.

Floor Bonds are carry trade infrastructure. Borrow at 3% from your prime broker. Lend at 4% into Floor Bonds. The spread is 1%. But the risk is near-zero. Lever it.

The same mechanics that powered the yen carry trade for decades. But backed by a structural floor rather than a central bank press conference.

Stress Tested

A Floor Bond issued at the worst possible moment — November 2021, near the all-time high, immediately before a 77% crash — survives. Debt peaks in Year 6 but never triggers liquidation. Self-liquidation crossover at Year 7.

Self-liquidation holds at safety factors as low as 70%. At interest rates up to 15%. The floor's 38% growth so dramatically exceeds any plausible rate that the crossover is invariant.

No Celsius. No BlockFi. No FTX.

Each Floor Bond creates a dedicated 3-of-5 multisig vault. The borrower holds two keys. No single party can move the collateral. No rehypothecation. No commingling. A timelock guarantees recovery even if the lender goes bankrupt.

Built on native Bitcoin primitives: Miniscript, PSBTs, hardware signing devices. Proven architecture (Unchained, Casa, Revault). Every vault is auditable on-chain in real time.

Institutional Scale

Applied to the top 5 corporate Bitcoin holders (25% pledged):

Strategy saves $247 million per year vs. STRC convertible debt. Same capital raised. 7.5% lower cost.

The Bigger Picture

Floor Bonds are the first instrument. The floor growth rate at different tenors forms a natural yield curve — the Bitcoin Floor Yield Curve.

1 year: 38%. 5 years: 30%. 10 years: 24%. 30 years: 15%.

This is to Bitcoin what the Treasury curve is to traditional finance. Floor Bonds price off the short end. Floor annuities off the long end. Mortgages, futures, options — all priced off the same curve.

A parallel financial system where the reference rate is Bitcoin's floor growth instead of Treasury yields. And every product is structurally superior because the reference rate is 38%, not 4.5%.
