Welcome to DeFi exec

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.

How much of a $200 account is exposed when I open a $50 perpetual position? The order size alone cannot answer that. Funding changes the balance over time, and cross margin determines which other funds can support the trade.

After comparing aggregator routes, I wanted to understand what happens when I leave an order waiting. A limit order authorizes a trade at an acceptable price. It does not promise that someone will execute it when a chart touches that price. CoW Protocol makes the distinction concrete: users submit signed trade intents, and solvers compete to settle them using available liquidity. CoW Protocol overview

An aggregator quote can offer more tokens and still leave me worse off after an extra approval or a more expensive route. For a $500 swap, I want to see the minimum output and total cost before choosing it.

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.
