Leverage & Liquidation

What Is Leverage?

Leverage means using borrowed capital to amplify your exposure to an asset. If you have $1,000 and borrow another $1,000 to buy ETH, you have 2x leverage — your gains (and losses) are doubled.

In traditional finance, leverage is routine. Mortgages, margin accounts, and corporate bonds all use leverage. In DeFi, leverage is everywhere — but the mechanism for enforcing it is uniquely brutal.

What Is Liquidation?

When you borrow in DeFi, you post collateral — an asset the protocol can seize if your loan becomes unsafe. The protocol watches the ratio between your collateral's value and your debt. If the collateral drops below a threshold (typically 110-150% of the debt), the protocol liquidates you: it sells your collateral to repay the debt, often at a discount.

Here's what happens during a liquidation:

You deposit $1,500 of ETH, borrow $1,000          Collateral ratio: 150%
                                                    (safe)
ETH drops 25%                                       ↓
Your collateral is now worth $1,125                 Collateral ratio: 112%
                                                    (approaching danger)
ETH drops another 10%                               ↓
Your collateral is now worth $1,012                 Collateral ratio: 101%
                                                    ↓
LIQUIDATION TRIGGERED                               A bot seizes your ETH,
                                                    sells it for ~$950,
                                                    repays $1,000 to the protocol,
                                                    keeps a $50 bonus,
                                                    and you get... nothing.

You lost your entire $1,500 position — not because you made a bad trade, but because of a temporary price dip. Even if ETH rebounds the next hour, your collateral is already gone.

Why Liquidation Is So Destructive

It's irreversible. Once liquidated, you can't get your collateral back. The position is closed permanently.
It happens at the worst time. Liquidations cascade during crashes. When ETH drops sharply, thousands of positions liquidate simultaneously, which pushes the price down further, which triggers more liquidations. This is called a liquidation cascade.
Bots front-run you. Liquidation is profitable for MEV bots. They race to liquidate positions before anyone else, earning the liquidation bonus. You have no time to add collateral.
It punishes conviction. If you believe ETH will be worth more in 4 years, it shouldn't matter if it drops 40% next Tuesday. But with liquidatable leverage, it matters enormously.

DeFi's Liquidation Problem in Numbers

Major liquidation events in DeFi history:

Event

Date

Liquidations

Black Thursday (MakerDAO)

March 2020

$8.3M liquidated, some at $0 bids

Terra/Luna collapse

May 2022

$1B+ liquidated across Aave, Compound, and Maker in a single week

FTX fallout

Nov 2022

$600M+ in DeFi liquidations as contagion spread

In every case, long-term holders lost positions not because their thesis was wrong, but because short-term price action triggered automated liquidation.

Types of DeFi Leverage

CDPs (Collateralized Debt Positions)

Used by: MakerDAO, Liquity, Aave

You deposit collateral, mint or borrow stablecoins against it. If the collateral value drops below the liquidation threshold, your position is seized.

Pro: Self-custody, transparent rules
Con: Always liquidatable. You must constantly monitor your health factor.

Leveraged Tokens

Used by: Index Coop, various DeFi protocols

Tokens that automatically maintain a target leverage ratio (e.g., 2x ETH). The protocol rebalances by buying more when the price rises and selling when it falls.

Pro: No margin calls, simple to hold
Con: Volatility decay — in choppy markets, the constant rebalancing bleeds value. A 2x leveraged ETH token can underperform over time even if ETH goes up.

Perpetual Futures

Used by: dYdX, GMX, Hyperliquid

Synthetic contracts that track an asset's price with up to 50-100x leverage. You pay (or receive) a funding rate to maintain the position.

Pro: High leverage, liquid markets
Con: Funding rates compound against you. A 0.01% hourly rate is 87% annually. Plus, you can still be liquidated.

Non-Liquidatable Leverage

This is the core innovation of ETH Strategy's convertible note structure. Here's how it works:

When you purchase a convertible note from the protocol (paying with ETH), you receive CDT (debt tokens) and an NFT option. The protocol acquires your ETH for its treasury. This gives the protocol leveraged ETH exposure — it holds more ETH than the equity (STRAT) backing alone would support.

Why can't this be liquidated?

Because the debt has no collateral ratio requirement. The convertible notes are:

Fixed-term (~4 years) — the debt matures at a set date, not when a price threshold is crossed
Zero-interest — no ongoing payments that could trigger default
Not oracle-dependent — no price feed determines whether the position is "safe" or "unsafe"

There is no liquidation threshold because there is no collateral ratio to monitor. The protocol simply holds ETH and owes a fixed USD amount at maturity. If ETH drops 50%, the protocol's leverage ratio increases — but nothing forces a sale. The protocol continues holding, and if ETH recovers, the full value is preserved.

Compare this to every other form of DeFi leverage:

The Trade-Off

Non-liquidatable leverage isn't free. The trade-off is:

The protocol owes a USD-denominated obligation. At maturity, CDT holders are entitled to redeem for their USD notional value (paid in esETH). If ETH has fallen significantly, the protocol must deliver more esETH per dollar — which dilutes the treasury.
Conversion dilutes STRAT supply. When note holders convert, new STRAT is minted. This dilution is the "cost" of the zero-interest borrowing.
The term is finite. Unlike a perpetual or an indefinite CDP, the notes expire. The protocol must refinance or pay off the debt at maturity.

These trade-offs are real, but they're predictable and manageable. The protocol knows exactly how much it owes, when it's due, and what the maximum dilution could be. Nothing can be called away early. No oracle can trigger a forced sale.

That's the difference. Liquidation is the risk of losing everything because of short-term price action. Non-liquidatable leverage eliminates that risk entirely, in exchange for known, bounded costs at a fixed future date.
