If you want to roll your own check out the Anchor Framework. There are also deployed contracts that you can use like Gem Farm.

To code in Rust and deploy contracts on solana, I would recommend the anchor framework https://github.com/coral-xyz/anchor

I am trying to run a local cluster for the example hello wold program on GitHub but I keep running into these pop-up errors when I run the "solana-test-validator" command and I'm not sure why. For context, I am on a machine running Windows 11, running cmd prompt in administrative mode, and I have tried re-installing the Solana CLI tool but am still seeing these errors.

If we use the Hello World program provided by Solana Labs as reference, that program increments a counter every time a user interacts with the program:

The Solana helloworld example client is written in TypeScript. I found it hard to read because its extensive use of global state. To try and help future users and to learn a little about it myself I made an implementation of the example client in Rust which I find to be slightly more readable.

In this article, we'll walk through the process of sending a custom instruction to a solana on-chain program. We'll modify the solana example helloworld to take two instructions, SayHello and SayGoodbye.

Solana has a nice hello-world example that shows us how to build a Rust program on Solana from scratch and interact with it using a typescript SDK.
