Soldity On Solana

In this lesson, you will:

Build the enhanced spl-token-minter program.
Deploy and test the upgraded program.

This lesson covers the process of building the upgraded spl-token-minter program. After successfully building the program, it guides you through the steps of connecting your wallet to the devnet, airdropping testnet tokens, and deploying the program. Subsequently, we test the deployed program to ensure its functionality.

Start by opening your project's root directory in the terminal and enter:

anchor build

This command generates a target folder in the project root and compiles idl and types of our Solana program for client-side interaction using RPC methods. Next, verify your configuration:

solana config get

The expected output should be:

Config File: ~/.config/solana/cli/config.yml
RPC URL: https://api.devnet.solana.com
WebSocket URL: wss://api.devnet.solana.com/ (computed)
Keypair Path: ~/.config/solana/id.json
Commitment: confirmed

Set your cluster to devnet:

solana config set --url https://api.devnet.solana.com

Generate a new wallet keypair:

solana-keygen new

Check your wallet address and balance:

solana address
solana balance

If necessary, airdrop Devnet SOL:

solana airdrop 4

Begin the deployment process:

solana-test-validator

Deploy your program:

anchor deploy

You should see a deployment confirmation:

Deploying cluster: https://api.devnet.solana.com
Upgrade authority: ~/.config/solana/id.json
Deploying program "spl_token_minter"...
Program path: /path/to/your/project/target/deploy/spl_token_minter.so...
Program Id: <Your Program ID>

Deploy success

Update the program IDs in both your Solidity file and anchor.toml file with the new IDs. Rebuild the program:

anchor build

Ensure all dependencies are installed:

yarn install
npm install

Run the tests:

anchor test

The output should indicate the success of the tests:

✨  Done in 12.26s.

This completes the process of building, deploying, and testing the upgraded spl-token-minter program. The successful tests confirm the program's ability to transfer tokens effectively within the Solana ecosystem.

In the next lesson, we will explore additional aspects of Solana's development, further enhancing our understanding and skills.
