No - Aven does not lend out, repledge, or rehypothecate your bitcoin collateral.
Some bitcoin-backed loan providers use a borrower’s bitcoin as collateral to secure their own loans or an affiliated exchange’s trading positions. This is called rehypothecation.
Rehypothecation is risky. If the bitcoin-backed loan provider defaults or becomes insolvent, borrowers might have a hard time recovering their collateral and, in rare cases, could lose it entirely.
