Ergo NFT Bulk Minter is a free, open source Python script that creates many NFTs on the Ergo blockchain in a single run instead of minting them one by one. It is aimed at developers, hobby artists and small creator teams who are comfortable working with code and a local Ergo node. The project uses the Ergo Node API and includes royalties in the minting process.
Before you start, know that the code was last updated in February 2022, so the project is more than two years old and may not match current Ergo tooling. Treat it as a starting point to study and adapt rather than a polished consumer app. Windows users run it through Python, which is covered in the installation section below.
What Is Ergo NFT Bulk Minter and Who Is It For?
Ergo NFT Bulk Minter is a script written in Python that automates the creation of several NFTs on the Ergo blockchain in one batch. Minting means recording a new token on a blockchain, and an NFT is a token that represents one unique item, such as a piece of digital art. Creating a few tokens by hand is manageable, but a collection of fifty or more items quickly becomes tedious when every entry needs the same steps.
The tool is most useful for people who already understand the basics of blockchain work. Developers who want to study or extend a minting script will find the source code readable. Artists and small teams with a prepared set of images and descriptions can process a whole collection in one run. Someone who wants a point-and-click experience with no setup will likely find it too technical, since it expects you to work with code, a local node and a metadata file.
It helps to separate the script from the platform. Ergo NFT Bulk Minter handles the minting logic, while the Ergo blockchain records the result. Marketplaces that display or sell your tokens are separate services with their own rules, so the script does not control how your NFTs appear elsewhere.
How Bulk Minting Works on the Ergo Network
When you mint through a node, the script prepares a transaction for each NFT and sends it to the node's API. The node uses the wallet it controls to sign those transactions, so access to that wallet is central to the whole process. Once the network accepts the transactions, the tokens appear in the wallet and can be transferred like other assets.
Each NFT carries information that describes it. The name, description and image link typically come from the metadata file you prepare, which the script reads entry by entry. Keeping this file clean and consistent matters, because the same structure is applied to every token in the batch. A typo copied across a spreadsheet will repeat across the whole collection.
Transaction fees are paid from the wallet for each action, so a large batch has a real cost even though the script itself is free. Running a short test first shows the actual cost per token before you commit to a full collection. Network confirmation takes whatever time the blockchain needs, so large batches may take a while to finish.
Practical Scenarios for Batch NFT Collections
Consider an illustrative artist who has 120 pieces in a generative series. Minting them one at a time through a wallet interface means repeating the same steps 120 times. With a batch script, the artist prepares one metadata file, checks each image link and runs a short test before minting the full set. Most of the time saved comes from preparation and review rather than repetitive clicking.
Another scenario is a small community project that wants to issue a collection to its members. A developer can generate the metadata from a spreadsheet, host the artwork and run the script from a Windows machine connected to a node. Because the process depends on the node staying online, the developer should plan when minting happens and make sure the node remains reachable throughout.
A third use is learning. Developers exploring Ergo's tooling can run the script on a test setup to see how node API calls and metadata work together, then adapt the code for their own needs. Since the project is open source, the logic can be modified, but changes should be tested on small batches before any large job runs.

How to install Ergo NFT Bulk Minter on Windows
- 1
Install Python and pip
Download Python only from the official website at python.org and run the installer. Make sure pip is included and that Python is added to your PATH. Open a Command Prompt and type python --version and pip --version to confirm both are working.
- 2
Get the project source
Open the project repository at github.com/mgpai22/ergo-nft-bulk-minter and download it as a ZIP archive, or clone it with Git. Extract it to a simple folder such as Documents\ergo-nft-bulk-minter. Because the project is distributed as source code, you run it through Python rather than double-clicking an installer. If a release page offers a Windows build, you may use it instead, but download it only from the official website or GitHub Releases.
- 3
Set up an IDE and dependencies
Open the project folder in PyCharm, which the project recommends. The Community edition works well for this purpose. Install any packages the project needs using pip from the project folder, and resolve errors before you move on to the node setup.
-
Connect an Ergo node and prepare files
Run an Ergo node and confirm that the script can reach its API and the wallet it needs. Prepare your image files, host them at links the script can access, and create the metadata file that lists name, description and image link for every NFT. Complete these steps before you run any minting command.
System requirements
- Windows with Python and pip installed, since the script runs through Python
- A running Ergo node with access to its wallet
- An IDE such as PyCharm Community Edition (recommended, not mandatory)
- Image files hosted at links the script can reach, plus a metadata file
How to use Ergo NFT Bulk Minter
Before you start, make sure your node is running and your metadata is ready. Working through a small test batch first helps you catch mistakes without spending much on transactions.
- Prepare your artwork and host each image at a stable link.
- Create the metadata file with a name, description and image link for every NFT.
- Start your Ergo node and confirm that the script can reach its API and wallet.
- Open the project in PyCharm or your preferred IDE and set the minting parameters, including royalties.
- Run the script on two or three items and check the resulting transactions in your wallet.
- Review the test tokens, correct any issues in the metadata, and then run the full batch.
- Keep the script output and logs so you can match each minted token to its metadata entry.
Pros & cons
- Free and open source, so you can read and modify the code
- Batch minting saves considerable time on large collections
- Royalty settings are built into the minting workflow
- Transactions run through your own Ergo node
- Readable Python code makes it useful for learning how minting works
- The code has not been updated since February 2022
- Requires Python, pip and a running Ergo node, which is not beginner friendly
- Works as a script rather than a graphical app
- Documentation covers prerequisites but offers little guidance beyond them
Is Ergo NFT Bulk Minter safe?
Ergo NFT Bulk Minter works with a node wallet that controls real ERG, so handle it with care. The last code update was in February 2022, so the project is more than two years old and has not been maintained recently. Download only from the official website or the project's GitHub repository, and check the latest version before you use it. If a release publishes a SHA-256 checksum, compare it with your downloaded file; if it offers a signature, verify it. Read the script before running it, especially any part that sends transactions. Never enter your seed phrase on third-party websites or into any prompt that asks for it. Test with a small batch and a wallet holding limited funds.
- Official source only. Download from github.com/mgpai22/ergo-nft-bulk-minter. Ignore ads and lookalike domains.
- Check the SHA-256. Compare the installer hash with the value the developer publishes before running it.
- Never share your seed phrase. No developer, support agent or website — including CryptApps — will ever ask for it.
Alternatives
Flutter Flow NFT Catalog is a different kind of project. It was built for a February 2023 hackathon and extends the Flow NFT Catalog toward a mobile app for browsing NFTs on the Flow blockchain. Its focus is on presenting and exploring NFTs, not on creating them. Ergo NFT Bulk Minter, by contrast, is aimed at creating many NFTs on Ergo from a metadata file. If you want to showcase or browse a collection, the mobile catalog approach may suit you better. If you want to mint a batch on Ergo from your own node, this script is the closer match, though it requires more technical setup.

Frequently asked questions
Yes, the script is free and open source, and you can download the code from its GitHub repository. Running it still involves transaction costs on the Ergo network, which are paid from your wallet for each NFT you mint. Plan a small test batch to see the actual cost before minting a large collection.
Yes, Windows is supported. You run the script through Python and pip, and you can use PyCharm Community Edition as your editor. The setup involves installing Python, extracting the project, and connecting to a running Ergo node before you start minting.
Yes. The script communicates with an Ergo node through its API and needs access to the node's wallet to send and receive transactions. Without a running node, the minting process cannot complete. Plan to keep the node online for the entire duration of a batch.
No. The tool is designed for the Ergo blockchain and its native coin, ERG. If you need minting on another network, you will need a different tool built for that chain. Check its documentation to confirm which blockchains and standards it supports before you begin.
The script includes royalty support as part of the minting workflow, so royalty terms are set when the tokens are created. Review your metadata and configuration in a test batch first to confirm the settings. Marketplaces handle royalty enforcement differently, so check how they treat the setting.
The last code update was in February 2022, so the project has not received updates for more than two years. It may still work for basic use, but it may not match newer versions of Ergo tooling. Review the code and test it carefully before relying on it for a production collection.
Some experience helps. You will need to install Python, use pip, open a project in an IDE and edit configuration values. Beginners can follow the installation steps and test with a few items, but the tool is better suited to people comfortable with basic command-line work.
Verdict
Ergo NFT Bulk Minter suits developers and technically confident creators who want to mint a batch of NFTs on Ergo through their own node. It is free, open source and readable, which makes it useful for learning and customization. The trade-offs are clear: the last update dates to 2022, setup requires Python, pip and a running node, and there is no graphical interface. If you need a quick, beginner-friendly tool, look elsewhere. If you are comfortable with code and plan to test carefully, it is a practical starting point.
