<h3>Setup Anchor Development Environment Instructions</h3> <h4>The steps below are compatible with Ubuntu 22.04</h4>

[!NOTE]
If you have Windows, please download VMware Workstation Player, install then create a virtual machine. Follow the tutorial video for full guidance.

VMware Workstation Player for Windows: https://www.techspot.com/downloads/downloadnowfile/1969/?evp=4c50cf08866937ea246522b86f4d4286&file=2171

Ubuntu Desktop 22.04 ISO: https://releases.ubuntu.com/jammy/ubuntu-22.04.4-desktop-amd64.iso

<h4>Step 1 Dependencies</h4>

sudo apt-get update && sudo apt-get upgrade && sudo apt-get install -y curl pkg-config build-essential libudev-dev libssl-dev

<h4>Step 2 Install Rust</h4>

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Press Enter When Prompted.

<h4>Step 3 Install Solana CLI</h4>

sh -c "$(curl -sSfL https://release.solana.com/v1.18.14/install)"

<h4>Step 4 Update PATH (UBUNTU ONLY)</h4>

nano ~/.bashrc

Add this line to end of file:

export PATH="/root/.local/share/solana/install/active_release/bin:$PATH"

save by : CTRL + X , Press Y, ENTER

Reboot PC.

Open back the terminal then confirm that Solana Cli is active by typing "solana" and press ENTER.

<h4>Step 5 Install NodeJS</h4>

curl -fsSL https://deb.nodesource.com/setup_20.x -o nodesource_setup.sh

sudo -E bash nodesource_setup.sh

sudo apt-get install -y nodejs

Verify Installation:

node -v

<h4>Step 6 Install Yarn</h4>

corepack enable
yarn init -2

Ignore Error: Internal Error: Process git failed to spawn

<h4>Step 7 Install Anchor</h4>

cargo install --git https://github.com/coral-xyz/anchor avm --locked --force

avm install latest
avm use latest

Verify Installation:

anchor --version

<h4>Step 8 Generate Dev Solana Wallet </h4>

<h3>Deploy SPL Token Program</h3>

Step 1 Build and Deploy SPL Program

<h5> A - Download Repo Folder SplToken</h5> <h5> B - Create a new Anchor project named "spl"</h5>

anchor init spl

<h5> C - Open the spl project folder in VS Code</h5> <h5> D - Replace the lib.rs file located in the programs/spl/src folder with the lib.rs file located in the downloaded SplToken folder</h5> <h5> E - Replace the cargo.toml file located in the project programs/spl folder with the cargo.toml file located in the downloaded SplToken folder</h5> <h5> F - Go to the Anchor.toml file located at the root of the project folder and change cluster to devnet.</h5>

[provider]
cluster = "devnet"

SAVE FILE!

<h5> G - Open terminal and proceed to build project then deploy.</h5>

anchor build

anchor deploy

<h5> H - Copy the program ID obtained once the deployment has completed.</h5> <h5> I - Go to target/types/spl.ts and update the address with the program ID obtained after anchor deploy.</h5>

export type Spl = {
  "address": "ENTERPROGRAMID",

SAVE FILE!

<h5> J - Go to target/idl/spl.json and update the address with the program ID obtained as well</h5>

{
  "address": "ENTERPROGRAMID",

SAVE FILE!

<h5> K - Go to programs/src/lib.rs and update declareid with the program ID obtained as well</h5>

declare_id!("ENTERPROGRAMID");

SAVE FILE!

Step 2 Create and Store Metadata in Arweave

Watch @ https://youtu.be/66o6qma2Jdc?t=3m40s

Copy the metadata.json Arweave path.

Step 3 Initiate SPL Token and Mint

<h5> A - Replace on spl project, the file tests/spl.ts with the spl.ts test file located in the downloaded SplToken folder</h5> <h5> B - Edit the spl.ts test file by providing the token metadata with your values and amount to initially mint.</h5>

const metadata = {
    name: "Net2Dev Rewards SPL",
    symbol: "N2DR",
    uri: "https://arweave.net/Xjqaj_rYYQGrsiTk9JRqpguA813w6NGPikcRyA1vAHM", //replace with Arweave metadata json path
    decimals: 9,
  };
const mintAmount = 10; // Amount of tokens to initially mint.

SAVE FILE!

<h5> C - Open terminal and proceed to run test.</h5>

anchor test

Step 4 Transfer Tokens to new Wallet from Owner Wallet

<h5> A - Copy the file spl-transfer.js from the downloaded SplToken folder and paste into the spl project folder</h5> <h5> B - Open terminal and install solana/spl-token sdk</h5>

npm i @solana/spl-token

<h5> C - Obtain the private key of the program owner as string, copy the value</h5>

Watch @ https://youtu.be/66o6qma2Jdc?t=55m30s

<h5> D - Edit the spl-transfer.js with the following values</h5>

const owner = 'REPLACEWITHSTRINGPRIVATEKEY' // private key string previously obtained 
const spltoken = new PublicKey("SPLPROGRAMID"); // Program Id of your SPL Token, obtained during "anchor deploy"

const tokens = 2; // set the amount of tokens to transfer.

SAVE FILE!

<h5> E - Create new solana wallet (Phantom Wallet for example) and copy address</h5> <h5> F - Add the new wallet address obtained previously to the spl-transfer.js as destination wallet </h5>

const destWallet = new PublicKey("NEWWALLETADDRESS");

SAVE FILE!

<h5> G - Run the Test and confirm that the ATA got generated and you got tokens on the new destination wallet!</h5>

node spl-transfer.js

Expected Result:

create ata txhash: 4uU9xegH7YZ3tTC934PBSzsVQf3pwoA5BWwXnpFpuK7aCTDu9yqK32r2Vjsbqz4vxhMReeL6NkmQ1hZPg3XSAXh8
Tokens transferred Successfully, Receipt: rttSvKXANuiTZkUmx1gj5B1jSH6bNz4NU64YmvqXouLYoWzqejot1NXxGrML7L87FWa2tX8WBDViKw8C5nmEZrC
