Solana programs are built in Rust! If you don't know Rust, you can read The Book here.

To install Rust just follow up this documentation.

We'll be using a nice CLI created by Solana, you can see installation instruction by looking here.

After installing the Solana CLI, run this command:

solana config set --url localhost

And now run this to make sure if we can get a local node up and running:

solana-test-validator

Archor is like Hardhat for Solana, and to install you can just run this:

cargo install --git https://github.com/project-serum/anchor anchor-cli --locked

solana config set --url devnet

// Make sure you're on devnet.
solana config get

anchor build

// Get the new program id.
solana address -k target/deploy/myepicproject-keypair.json

// Update Anchor.toml and lib.rs w/ new program id.
// Make sure Anchor.toml is on devnet.

// Build again.
anchor build

// Deploy
anchor deploy
