FAQ

Sometimes, things are not working as expected or you ran into a new situation and got stuck. Here are the most common problems and their solutions you may run into

How can I update an existing installation?

The same way you installed it the first time

To see which is the most recent version available you can look into the Github repository or NPM. To check your current installed version run

I forgot my PIN

I want to change the Pinning Service

I want to use another account

You can always reset your profile and re-initialize it

What is the maximum number of NFTs per collection?

The current maximum is 99999

I already created a collection via the web interface. Can I add more NFTs using this tool?

Yes, you can using the continuation command (see also Continue a collection)

My upload failed due to network issues (or other technical problems). What can I do?

The tool remembers the last successful processed operation when generating artifacts, or uploading/minting NFTs. So, you can try to repeat the interrupted command. It will continue where it stopped before. If you still have trouble, you might have a look into the log files which are created in your collection folder.

If you got stuck, don't hesitate to ask us on Discord. If you intend to open a bug report on Github, please attach the error from the log file (not the entire log file) to provide valuable details, which helps us to investigate and (hopefully) quickly fix the problem

Can I upload to Testnet also?

For sure. When you Configure your profile you can select the network.

Can I use my local node for minting?

Yes. Everytime, the tools needs to connect to the Signum network, it checks for fastest responding node, including locals. If you run a local node it should be selected automatically.

Can I configure an arbitrary remote node?

No. At this time of writing this is not possible. The automatic node selection is restricted to the featured network nodes and your local one

Why do I need to edit the CSV file? Can't this be done automatically?

There are many different art generators outside in the wild which generate different meta data files of different formats. The problem is that these generators not even provide all information, i.e. listing mode. The principal problem is the mapping and this requires some manual work. Furthermore, NFTs on the Signum Network follow Signums own SRC-40 standard and is not compatible with any Ethereum-like standards. This is, because Signum has its very own virtual machine (VM) for running smart contracts, which - by the way - even existed before Ethereum was born. This means that the structure to describe the NFT is different from that of ERC-20 or ERC-721.

This is the reason why the intermediate format was defined, though allowing efficient mass editing within MS Excel and alike tools and even opens the door for the community to write their own converters for the existing generators.

What is that Pinning thing?

Media files are big files which aren't stored on the blockchain. Blockchain space is extremely valuable and though costly. It would be possible to store data on cloud storage providers like AWS S3 and similar, but this is a centralized concept which comes with its very own issues (to be clear: not all is bad about S3). Fortunately, there exists an almost decentralized, and foremost heavily distibuted storage solution called IPFS. The files in that storage network are redundantly stored on so called peers all over the world. Unfortunately, inside the IPFS protocol exists a concept of garbage collection, i.e. removal of unused documents. To prevent loss of your media files one needs to tell the garbage collector, that the document must not be deleted. This process is called pinning - behind the scenes we run a dedicated pinning process to guarantee that all media files are pinned.

Why do I need my own Pinning Keys?

Actually, those keys are not really used for pure pinning, but for upload to IPFS. The services, namely Pinata and NFT.Storage, are a comfortable way to upload media files to IPFS without the need to install additional software, like an IPFS node, on your computer. We might have used our own pinning service - and maybe we will provide it in the future -, but we focused primarily on the platform itself and use existing services. Additionally, we also favor the idea of decentralization, where it's vital that people have control over their things, following the idea of: Your Keys, Your Control.
