# Oracle (Native) This program will store the price of some asset in an account owned by this program. Only an authorized account will be able to update the price. Complete all tasks below - Implement an oracle program - Test locally with LiteSVM - Deploy locally to `solana-test-validator` and test with Rust script # Task 1 - Implement [`instructions::init`](https://github.com/Cyfrin/solana-course/blob/main/apps/oracle/native/exercise/src/instructions/init.rs) - Check that `oracle_account` is not initialized - Store the `owner` and `price` into `oracle_account` - Call `instructions::init` inside `lib.rs` # Task 2 - Implement [`instructions::update`](https://github.com/Cyfrin/solana-course/blob/main/apps/oracle/native/exercise/src/instructions/update.rs) - Check that the `oracle.owner` signed this instruction to update the price - Update the price - Call `instructions::update` inside `lib.rs` # Build ```shell cargo build-sbf ``` # Test ```shell cargo test -- --nocapture ``` # Test with script Run local validator ```shell solana config set -ul solana-test-validator ``` Deploy program ```shell solana program deploy ./target/deploy/oracle.so ``` Execute demo script ```shell PROGRAM_ID=your program ID RPC=http://localhost:8899 KEYPAIR=path to key pair cargo run --example demo $KEYPAIR $RPC $PROGRAM_ID ```
