How does this work?

We aren't creating a " cryriptocurrency " (what??), but we are creating a Token.

`Token creator` - The easy way

With 'solana-token-creator' you can create a crypto within 2 minutes with just 1 command!

The token creator is not compatible with Windows!
But if you are a windows user you can use WSL, Google cloud or a VM to use the script

Download this repo

git clone https://github.com/tm01013/how-to-make-your-own-crypto.git
cd how-to-make-your-own-crypto

Open Terminal then enter the following command:
```
bash solana-token-creator.sh
```
The program will ask you if you want to install the needed software. You will need to say "y" at the first time (or when you want to update)

Then close and reopen Terminal (it's necessery to work correctly)
Can you make your crypto within 2 minutes? :)

Command line arguments

command line option	details
--advanced	gives you some extra options
-r --recipient	recipient's wallet
-d --decimals	token decimals [1-10]
-e --extensions	extensions (separated by commas) Details - no extension -> n / 0 / noextension - non transfarable -> nt / 1 / nontransfarable - confidential transfer -> ct / 2 / confidentialtransfer - transfer fee -> tf / 3 / transferfee - transfer hook -> th / 4 / transferhook - permanent delegate -> pd / 5 / permanentdelegate - mint close -> mc / 6 / mintclose - intrest bearing -> ib / 7 / intrestbearing - default account state -> das / 8 / defaultaccountstate - freeze -> f / 9 / freeze - group config -> gc / 10 / groupconfig - member config -> mc / 11 / memberconfig
-th --transfer-hook	transfer hook program id
-tf --transfer-fee	transfer fee in percentage
-mf --max-fee	max fee in tokens
-ir --intrest-rate	intrest rate
-das --default-account-state	default account state, initialized(i) or frozen(f)
-gc --group-config	group config (address / max amount of tokens that can belong to the newly initialized group)
-mc --member-config	member config (address / leave empty to initialize a new)
-na --name	token name
-s --symbol	token symbol
-ds --description	token description
-i --icon-url	icon url
-m --offchain-metadata	off-chain metadata url
-k --keypair	token keypair (location of the keypair file)
-a --amount	token amount (in tokens)
-n --network	network, mainnet(m) / devnet(d) / not change(n) / custom rpc url

Don't use empty strings in cli arguments, it will brake the script!

On-chain updater mode

With this mode you can update the on-chain metadata, extension settings and the authoritys of your token:

bash solana-token-creator.sh --updater-mode

Cheat sheat

Yes, this program has a builtin cheat sheat for the most used solana and spl commands!

bash solana-token-creator.sh --cheat

If you have other suggestions what to put in the cheat sheat create an issue with the 'cheat sheat' label, or open a PR.

Tools

With this feature you can do unregular solana stuff easyly!

bash solana-token-creator.sh --tools

`Manual way` - Learn things in the harder way

I. Installation of tools

Mac (Terminal), Linux (Terminal), Google Cloud console :

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

Then restart Terminal to work everithing fine and enter the following command:

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

Windows (cmd):

cmd /c "curl https://release.solana.com/stable/solana-install-init-x86_64-pc-windows-msvc.exe --output C:\solana-install-tmp\solana-install-init.exe --create-dirs"

C:\solana-install-tmp\solana-install-init.exe v1.16.9

Then restart cmd to work everithin fine

II. Token creation

Create a new solana wallet
```
solana-keygen new
```
Warning this will remove your existing wallet!!
This creates a new Solana key pair that will function as a file system wallet.
Before generating the key pair, it will ask for a BIP39 Passphrase, which serves as extra protection, but we don't need it .
Save the public key, we need it later!
Check Solana configuration
```
solana config get
```
If you do not see api.devnet.solana.com in the RPC line, you are not on the developer network, then you have to pay for the creation of the token (+ for the transactions), nothing on the developer network has a real monetary value.

Solana has 3 main networks:
- Mainnet: real money, transactions have real fees, RPC: https://api.mainnet-beta.solana.com
- Devnet: not real money, transactions have simulated fees , RPC: https://api.devnet.solana.com
- Testnet: similar to devnet , but its purpose is to test the solana network, RPC: https://api.testnet.solana.com
If you want to create a token for free , you can "enter" the developer network with this command.
```
solana config set --url https://api.devnet.solana.com
```
You have to transfer Solana to your account, with this command you get 4 test SOLs.
```
solana airdrop 4
```
If you are not on the developer network, you have to transfer some SOL from your own account here.

Salana is needed because you have to pay for token creation + subsequent transactions
These 4 SOLs are enough for more than 800000 transfers on the dev network.
Create a token
```
spl-token create-token -p TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb --enable-metadata <optional flags>
```
When creatin a token you can configure the following things:
1. --decimals <DECIMALS> Number of base 10 digits to the right of the decimal place [default: 9], minimum is 1 (for fungible tokens)
2. --mint-authority <ADDRESS> Specify the mint authority address. Default is the client's address.
3. Token Extensions, see the my Token Extensions guide and the offical docs
Save the token address, we need it later!

You can create several different tokens with one wallet. So if you are not satisfied with one token, you have to repeat the process from this step :)
Creating an account for our token
```
spl-token create-account -p TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb <token>
```
This will not create a new wallet but an account within the wallet for the token
For all tokens you need an account to store them, and these accounts are inside the wallet.
There is a fee to create an account (less than 0.00001 SOL)
You can generate a certain amount of token with this command
```
spl-token mint <token> <amount>
```
Only the mint authority (the wallet that created the token) can mint tokens
Use this command to check how many tokens you have
```
spl-token accounts
```
Use this command to disable the generation of additional tokens
```
spl-token authorize -p TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb  <token> mint --disable
```
Do not perform this step until you have added metadata to your token!!

IV. Add metadata to the token

Without metadata the token will apear as “Unknown Token”, and it won't have an icon and symbol (eg:BTC).

Chose a name (Example Token), a symbol (ET) and a description (Best token!)
Upload your icon (in png format) to GitHub ar any other site and get it's raw link (ending with .png)

Create a off-chain json metadata file like this:

{
  "name": "Example Token",
  "symbol": "ET",
  "description": "Best Token :)",
  "image": "https://example.com/image.png",
  "attributes": [],
  "properties": {
    "files": [
      {
        "uri": "https://example.com/image.png",
        "type": "image/png"
      }
    ]
  }
}

Upload the metadata file to npoint.io or GitHub, and get it's referance link

IMPORTANT! On npoint.io don't forget to save! The referance link will be on the bottom of the page!

Add the on-chain metadata

spl-token initialize-metadata <token> <token name (in quotation marks)> <token symbol (in quotation marks)> <off-chain metadata referance link> -v -p TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb

Check the metadata on Solscan, Solscan for devnet

Search with the token's address

Don't worry if you see your token as "Unrecognised Token" just wait 2-4 minutes to let the network process the changes
Your token is DONE :)

V. Use the Token

Create a wallet suitable for storing Solana, for example, in the Phantom app (Android , IOS , Chrome extension).
If you created the token on the developer network, you must switch the network from "Mainnet" to "Devnet" in the wallet app.
- Phantom : "Settings" => "Developer settings" => turn "Testnet mode" on => select devnet
  
  After this you should see a yellow stripe at the top of the screen (after restarting)
- Solflare : Settings => "General" => "Network" => "Devnet"
- Not All applications are compatible with the developer network!
Send the test SOL retrieved in the "Create Token " section to your new wallet ( you will need it for the transfers 1SOl = >200000 transfers).

If you are not using the test network, you have to transfer SOL to your new account in another way.
```
solana transfer <wallet Solana address> <amount (some must remain to fund the transaction)>
```
You can only transfer to SOL with this command .
Send the completed tokens to your wallet and at the same time create an account for the token there (--fund-recipient).
```
spl-token transfer <token> <amount> <address of the destination wallet> --fund-recipient
```
Don't worry if you see your token as "Unrecognised Token" just wait 2-4 minutes to let the network process the changes

Don't forget that you will always need SOL for transactions (if you use the test network and run out, complete steps II/4 and V/3)
