+# sol-anchor-contract
+
+This is a program developed as a Rust Smart Contract(Solana Blockchain).
+It acts as an example for developers who are new to Solana ecosystem to learn on how the program interacts with the Pyth Oracles. 
+
+Instructions of the program:
+
+1. init
+2. loanToValue
+
+Please find below instructions on running the Smart Contract on local cluster:
+
+1.
+
+- Open a new terminal
+- Run below command which clones two account addresses and their associated data into local cluster from devnet cluster.
+
+solana-test-validator --reset --clone EdVCmQ9FSPcVe5YySXDPCRmc8aDQLKJ9xvYBMZPie1Vw 38xoQ4oeJCBrcVvca2cGk7iV1dAfrmTR1kmhSCJQ8Jto --url devnet
+
+2.
+
+- Open a new terminal.
+- Run below command which listens to transaction logs.
+
+solana logs
+
+3.
+
+- Open a new terminal.
+- Navigate to the root directory of your application.
+- Build and then deploy.
+- Run below command
+
+anchor test --skip-local-validator
+
+NB
+
+When tetsing on local cluster you may encounter error "Pyth price oracle is offline.", please find below one of the approaches of addressing it.
+- On file "src\lib.rs", change the value "60" to a higher figure on these lines of code ".get_price_no_older_than(current_timestamp1, 60)"
+and ".get_price_no_older_than(current_timestamp2, 60)". This should just be for testing purposes on local cluster.
