If you have the Solana CLI installed locally: update the LOCAL_PAYER_JSON_ABSPATH environment variable to be the absolute path of your local testing wallet keypair JSON file.

Recommended flow to explore this repo

After setting up locally, I recommend exploring the code of the following files (in order):

• 1.simpleTransaction.ts
• 2.complexTransaction.ts
• 3.createTokenWithMetadata.ts
• 4.mintTokens.ts
• 5.updateMetadata.ts
• 6.createNFTs.ts

After reviewing the code in each of these scripts, try running each in order.

Note: Running each of these scripts may save some various bits of data to a .local_keys folder within this repo for use by the other scripts later in this ordered list. Therefore, running them in a different order may result in them not working as written/desired. You have been warned :)
