Aave

If an Aave price feed stops updating but keeps returning a positive number, does the protocol switch to another oracle? That question matters more to me than how many feed addresses appear in a dashboard. A lending position depends on the prices accepted for both its collateral and its debt.

If I need to sell Aave collateral to repay debt, the order of operations matters. A flash loan can supply the repayment asset first, so the transaction can repay debt, withdraw collateral, sell it, and settle the temporary loan.

Printing health factor in a terminal is useful until the terminal closes or the RPC stops answering. I want the watcher to tell me when the position needs attention and when its own reads are failing.

A supply-only position has no debt to liquidate. A borrow adds a repayment obligation and a collateral threshold I need to understand before opening it.

For a first lending deposit, I want to understand the receipt token and withdrawal path before adding debt. Supplying $200 of USDC is enough for this walkthrough.
