⏱️ Why does your screen show one price while the contract reads another?
A contract that queries the price of $ETH from a Chainlink oracle reads the latest data published on the network. An update can be triggered when the change exceeds a threshold or a time interval has elapsed.
🧩 Hypothetical example: the screen reflects a small increase. The contract still reads the previous data because the movement hasn’t reached the threshold and the interval hasn’t elapsed.
🛡️ In a lending app, an outdated price can distort the estimated value of collateral. The time of the last update helps explain the discrepancy.
