How to choose between two lending markets
Lending protocols look interchangeable from the outside — supply an asset, earn a rate, borrow against collateral — and differ sharply in the two places that decide outcomes: what happens when collateral falls, and who can change the rules while your position is open.
- Liquidation design. What loan-to-value is allowed, at what threshold liquidation triggers, and what bonus liquidators receive. A larger bonus means faster liquidation and a bigger loss to the borrower.
- Risk isolation. Whether one bad collateral asset can create bad debt affecting all suppliers, or is contained to its own market. Isolated designs limit contagion at the cost of fragmenting liquidity.
- Oracle. Where prices come from and how manipulable they are. Oracle failure is the most common route to a lending protocol becoming insolvent.
- Rate model. How borrowing costs rise with utilisation, and how sharply. A steep curve protects supplier withdrawals and makes borrowing costs volatile.
- Governance surface. Whether parameters can change under a live position, and whether a timelock gives you notice.
What goes wrong with either choice
- Liquidation during a fast move. Bots act within seconds; there is rarely time to add collateral.
- Bad debt from an oracle failure or a collateral asset that becomes illiquid faster than liquidators can exit it.
- Utilisation spikes that raise borrowing costs sharply and can delay supplier withdrawals until borrowers repay.
- Governance changing a risk parameter under a live position.
- Smart contract risk in both protocols, which auditing reduces and does not remove.
