What is Leverage?
Leverage in DeFi is the use of borrowed funds to amplify trading positions or yield strategies — multiplying both potential gains and losses relative to the initial capital invested.
WHY IT MATTERS
Leverage lets you control more value than you own. Deposit $1000, open a 5x leveraged position, and you control $5000 of exposure. If the price moves 10% in your favor, you gain $500 (50% on your capital). Against you: lose $500.
DeFi leverage sources include: lending protocols (borrow against collateral and reinvest), perpetual swaps (built-in leverage), leveraged yield farming (amplified LP positions), and flash loans (single-transaction leverage).
Leverage is a double-edged sword. It amplifies returns in good markets and amplifies losses in bad markets. Liquidation risk increases with leverage — at 10x, a 10% adverse move wipes out your position.
