In this guide, we will walk through the process of setting up a script for quick minting DRC-20 tokens. This script will automate the process of minting, making it more efficient and user-friendly.

{% hint style="success" %} <mark style="color:green;">**Splitting UTXO is requiered for the script below:**</mark><br>

<mark style="color:green;">Splitting UTXOs allows you to process multiple transactions concurrently, enhancing the efficiency of the minting process.</mark>

<mark style="color:green;">To split your UTXOs, use the command:</mark>

```bash
node . wallet split <count>
```

<mark style="color:green;">Replace</mark> <mark style="color:green;"></mark><mark style="color:green;">`<count>`</mark> <mark style="color:green;"></mark><mark style="color:green;">with the number of splits you want to make.</mark> \ <mark style="color:green;">**We recommend splitting into 50 UTXOs for optimal results.**</mark>
{% endhint %}

**You'll need to install bc dependencies for the calculations / colors features:**&#x20;

```
sudo apt-get update
sudo apt-get install bc
```

{% hint style="danger" %} <mark style="color:red;">**The script won't work properly if bc isn't installed.**</mark>
{% endhint %}

**Below is a shell script that you can use for this purpose:**

Simply launch the command:&#x20;

```
nano YOUR_BULK_FILENAME.sh
```

And copy the following script:&#x20;

```bash
#!/bin/bash

#check that 3 arguments are passed in otherwise exit
if [ "$#" -ne 3 ]; then
    echo "Illegal number of parameters"
    echo "Usage: <YOUR_BULK_FILENAME.sh> 0 <YOUR WALLET> <TICKER>"
    exit 1
fi

count=0
max_count=4
total_transactions=0
total_cost_doge=0
total_cost_usd=0
target_address=$2
token_name=$3
RED='\033[0;31m'
GREEN='\033[0;32m'
NC='\033[0m' # No Color
while true; do
    while [ $count -lt $max_count ]; do
        echo "Current count: $count"
        node . drc-20 mint "$target_address" "$token_name" <AMOUNT> 12
        remaining=$((max_count - count))
        echo "Counts left: $remaining"
        sleep 5  # Sleep for 5 seconds
        ((count++))
        ((total_transactions+=12))  # Add 12 to the total transactions count
        total_cost_doge=$(echo "$total_transactions * 0.031" | bc)
        total_cost_usd=$(echo "$total_transactions * 0.07 * 0.031" | bc)
    done
    echo -e "${GREEN}Total transactions sent: $total_transactions${NC}"
    printf "${RED}Total cost in DOGE: %.2f${NC}\n" $total_cost_doge
    printf "${RED}Total cost in USD: %.2f${NC}\n" $total_cost_usd
    rm pending-txs.json
    sleep 5
    node . wallet sync
    sleep 5    
    node . wallet sync
    sleep 600
    count=0
done
```

{% hint style="danger" %} <mark style="color:red;">**You'll need to replace :**</mark> \ <mark style="color:red;">\<YOUR\_BULK\_FILENAME.sh> : With the name of your .bash file, e.g : bulk-fiwb.sh</mark>\ <mark style="color:red;">\<YOUR WALLET> : With the wallet that will receive the inscriptions</mark>\ <mark style="color:red;">\<TICKER> : With the token you want to mint, e.g : fiwb</mark>\ <mark style="color:red;">\<AMOUNT> : With the max limit amount per mint of this ficker, e.g : 50 (for fiwb)</mark>
{% endhint %}

{% hint style="warning" %} <mark style="color:orange;">**Don't forget to run the following command once your .sh file is created!**</mark>&#x20;

<mark style="color:orange;">chmod +x YOUR\_BULK\_FILENAME.sh</mark>
{% endhint %}

#### To start the bulk, just launch the following command :

```
/YOUR_BULK_FILENAME.sh 1000 <WALLET> <TICKER>
```

You can now go to sleep, the node will handle the rest ! :clap:

### Understanding the Script

#### The Basics

The script uses a while loop to automate the minting process. \
Inside the loop, a series of commands are executed, and after each cycle, the script sleeps for a certain amount of time before the next cycle begins.

#### Parameters

At the beginning of the script, we check to ensure that three arguments are passed when you call the script. If not, an error message is displayed, and the script exits. These arguments are:

1. A zero (0) - This is a placeholder for future use.
2. Your wallet address - This is where the minted tokens will be sent.
3. The token name - The token you are minting.

#### Variables

Several variables are used to manage the minting process, track the total transactions, and calculate the total cost in DOGE and USD. These are `count`, `max_count`, `total_transactions`, `total_cost_doge`, and `total_cost_usd`.

#### Looping and Minting

In the main loop of the script, the `node . drc-20 mint "$target_address" "$token_name" 50 12` command is run to mint the tokens. The `count` variable tracks the number of times this command has run, and `remaining` calculates how many more times it will run before reaching `max_count`.

#### Updating and Syncing

After reaching `max_count`, the script removes the `pending-txs.json` file and syncs the wallet by running `node . wallet sync`. The script then sleeps for 600 seconds (10 minutes) before starting the next cycle.

{% hint style="warning" %} <mark style="color:orange;">**This script won't stop until you decide to shut down the process by yourself.**</mark>
{% endhint %}

#### Colors

Colors are used to make the output more readable. \
Transactions sent are displayed in green, while the total cost in DOGE and USD is shown in red.

**Note:** \
To use this script, you need to install Git Bash for Windows. \
For VPS, you just need to use a terminal.

**Enjoy your quick minting journey!**
