In one sentence: an investor supplies capital as SOL, held in a self-custodied multisig they control. A small, over-collateralized loan (~10% LTV) is drawn against it and off-ramped to EUR to fund airKUNA’s development. Because the loan is tiny relative to the collateral, the yield the collateral earns exceeds the loan interest many times over — so the loan is retired from carry, and the investor keeps their SOL exposure plus an allocation in airKUNA.
The stack — independent, composable primitives
None of the financing depends on airKUNA building anything new. Every layer is an existing, independently-operated protocol; airKUNA is only the treasury recipient at the end of the rail.
How it works — the state machine
The capital moves through six states. The only leg that touches airKUNA is the treasury deposit; everything else is the investor’s own self-custodied position.

Model it yourself
Adjust the assumptions. The model is deliberately conservative: it estimates loan self-repayment from carry only, holding SOL price flat, then shows price upside separately. Everything is an illustration, not a quote.

Risk engine — stated plainly
The architecture reduces some risks and accepts others. It does not eliminate them. Here is each material risk, how it is mitigated, and the residual exposure.
| Risk | Mitigation | Residual exposure |
|---|---|---|
| SOL drawdown → liquidation | ~10% LTV keeps the liquidation price ~85% below spot; Hobba’s risk engine can auto-deleverage before that. | moderate A fast, deep crash can still outrun automated deleveraging; oracles can lag. |
| LST de-peg (e.g. JitoSOL) | Blue-chip LSTs, conservative collateral factors, dynamic rebalancing. | moderate A sustained LST de-peg lowers collateral value and can trigger liquidation. |
| Borrow-rate spike | Debt is tiny vs collateral, so interest can rise several-fold before carry turns negative. | low Only bites if borrow APY exceeds yield APY on the whole collateral. |
| Stablecoin risk (USDC/EURC) | Full-reserve, attested, MiCA-framework issuers; short holding window during off-ramp. | moderate Issuer/reserve/regulatory failure is possible, if unlikely for blue-chips. |
| FX (USD/EUR) | Off-ramp to EUR happens near-immediately, minimizing the window of exposure. | low Debt and treasury are both EUR-denominated after off-ramp. |
| Smart-contract / bridge | Established protocols, audits, multisig on the vault. | high impact Exploits happen. This is the tail risk that can zero the position. |
What the investor gets
- Retained SOL exposure — the principal stays the investor’s, in self-custody, with full upside (and downside) on SOL.
- An allocation in airKUNA — the off-ramped EUR funds development; the size and instrument of any equity/allocation are set by a separate, formal agreement, not by this page.
- Non-dilutive funding for airKUNA — development is financed without selling core equity or tokens at a market bottom.
