-`query_price_feed` makes a query to the Pyth Network Terra contract
+`query_price_feed` makes a query to the Pyth Network CosmWasm contract
 This query requires a price feed id that indicates the product whose price should be returned.
 Each product listed on Pyth Network (e.g., BTC/USD) has its own price feed id; see the [Contracts and Price Feeds](#contracts-and-price-feeds) section below for the possible products and their price feed ids.
 The result of the query is a `PriceFeed` struct which contains the current price of the product along with additional metadata.
 This struct also has some useful functions for manipulating and combining prices; see the [common SDK documentation](../pyth-sdk) for more details.
 
 ## Off-Chain Queries
