Added example to mint compressed NFTs #9

| 1. The Bubblegum program, developed by Metaplex, plays a role in verifying the metadata (information) linked to an NFT (non-fungible token). | ||
|
|
||
| 2. When Bubblegum is activated, it uses a process called "account-compression" to add a new data point (called a "leaf") to the Merkle tree structure. |

nit: "invoked" instead of "activated"

🔑 - I would rather see you generate keypairs using JavaScript code, than loading ones from local disk.
Users that are checking out these scripts should be able to clone, install dependencies (yarn | npm ) and then run the script and get their cNFT

if we want users to directly clone and mint the cNFTs, should I add the keypair json to it?
I am generating keypairs using solana-cli tho

Why can't you do it with JavaScript code instead?

Yeah! That would be better. Let me check if I can generate using the keypairs with fixed starting letters like we do using grind in solana-cli

| async function main(){ | ||
|
|
||
| const keypair = loadWalletKey("CNFT.json"); |
|
|
||
| async function createTree() { | ||
| // Load the wallet key for the user who will create the merkle tree | ||
| const keypair = loadWalletKey("CNFT.json"); |
|
|
||
| async function mintOneCNFT() { | ||
| // Load the wallet key for the user who will mint the CNFT | ||
| const keypair = loadWalletKey("CNFT.json"); |

Again, see 🔑
Pretty much anywhere you're loading local JSON keys
| import { loadWalletKey, sendVersionedTx } from "./utils"; | ||
| import { Connection, Keypair, PublicKey, SystemProgram, Transaction, VersionedMessage } from "@solana/web3.js"; | ||

You can just use SystemProgram.programId from @solana/web3.js for this
