The mechanic
One cycle, starting from an asset that earns yield:- Supply the asset as collateral.
- Borrow a second asset against it, typically a stablecoin.
- Swap the borrowed asset back into the first asset.
- Supply the proceeds as additional collateral.
Why anyone does it
The intent is to earn the spread on a larger base. If the collateral yields more than the debt costs, multiplying the collateral multiplies the spread. The arithmetic in Net APY shows how a 2-point spread can present as a double-digit return on committed equity.Why the loop terminates
Each cycle is bounded by the market’s max borrowable LTV, so the amounts shrink geometrically. At an 85% max LTV the theoretical ceiling on total exposure is about 6.7× your starting capital. You will not reach it, and should not try:- The 3% safety margin applies to every borrow, so each cycle draws less than the theoretical maximum.
- Swap slippage and fees consume part of every cycle.
- Approaching the ceiling drives your health factor toward 1.00 and then below it, which is where liquidation risk becomes acute.
