+# Warning: do not hardcode price feed updates in your contract
+`update_single_price_feed` is meant to be called in a chain of programmable transactions, rather than hardcoded in a contract. This is because when a Sui contract upgrades, the upgraded version lives at a different address. When this happens the previous callsite gets bricked, or becomes un-callable. It is up to the user to use the correct call-site (we also have a helper function for finding the latest call-site given the Pyth state object ID, which is unchanged between upgrades).
