Spaceseven allows users to transform digital content into NFTs residing on the blockchain. The digital content could include books, images, videos, musical tracks, or even complex digital files. Users can just enter the details for describing their item and use the Concordium blockchain for taking their digital item to the public. Users could browse the Spaceseven marketplace for making bids and purchasing digital items. The items reside on the blockchain and belong to your wallet when you purchase them.
NFT stands for Non-fungible token.
Think of an NFT as a digital stamp of ownership used to confirm the authenticity of a unique item. At the moment that stamp is recorded (tokenized) on a secure public database (blockchain), the stamp becomes verified as one of a kind and cannot be modified or copied.
An item is fungible if it can easily be exchanged or substituted and maintain its same value. A dollar bill is an example of a fungible item because it can be replaced or exchanged for 4 quarters and still retain the same exact value. Other fungible items include:
Gold
Bitcoin or other crypto currencies
Casino chips
An item is non-fungible if it cannot be substituted because it has unique qualities that make it different from other similar items. While many NFTs are digital, they can be used to verify the authenticity of real-world items too. Examples include:
Event tickets
Photography
Collectibles like trading cards
Music
Digital art
Virtual items like video game skins and avatars
Tangible assets like real estate, cars, and even designer clothing
It is that publicly verifiable ownership that makes NFTs valuable because it allows them to be easily and securely traded or sold and allows for a variety of additional uses like:
Unlock owner benefits like exclusive access to an event or an experience
Artist/creator royalties
Chain of custody verification, eliminating ticketing fraud
On the open market, a 7.5% platform fee will be deducted from all sales. This means that over and above the royalty fee set, a 7.5% platform fee will be deducted from the sale.
This will also be applied to the Universe sales on both primary and secondary sales. The % is different from the open marketplace and is agreed upon within the contractual terms with each partner.
A smart contract is a self-executing transaction protocol, or a piece of programming code, to put it simpler. This code is used for inputting all the terms of the agreement concluded between the parties to the transaction in the blockchain.
What makes this transaction protocol so important? The thing is that it regulates relations between sellers and buyers on NFT marketplaces.
Obligations of parties are represented in smart contacts in the form of if/then. For example, if a buyer transfers the payment for a digital item, then a seller grants the right to this NFT crypto asset. Provided that the condition is met, the smart contract conducts the transaction independently.
Non-fungible tokens are implemented via smart contracts. Each item comes with unique metadata. This set of the specific information related to supply, provenance, and authenticity is written in smart contracts. Blockchain technology carefully protects this data.
For a token marketplace development, we need to create a token protocol. As a rule, these protocols are created on the Concordium network, which is a particular group of smart contracts. They enable the implementation of certain marketplace functionality. Later on, token protocols will be integrated into the process of NFT marketplace development.
Currently we do not have the option to view the NFT smart contract until the Concordium blockchain upgrade happens in May 2022.
You will need to connect your crypto wallet to buy an NFT on the SpacesevenMarketplace. The transaction will process through your wallet which will transfer the NFT to you after payment.
The process of registering an item as a token on the blockchain. The minting adds a permanent stamp of authenticity and uniqueness. Similar to the way that physical metal coins are minted and added into circulation, NFTs are also tokens that get “minted” once they are created.
The minting process also ads key elements of value, the unchangeable rules by which that token will function in the form of a smart contract and the chain of ownership. Once a token is minted, it can no longer be altered.
We are unable to issue refunds as transactions on the blockchain are irreversible. We have no ability to cancel, revert, or modify any transactions on the Concordium network.
No, please only select one category per mint
The NFT will be available in your crypto wallet.
The percentage chosen when minting, will be deducted from the secondary sale. Meaning that the original creator will receive that percentage allocation for all sales on the secondary market.
E.g.
I bought an NFT where the royalty set was 10%.
I've decided to re-sell it for 200 CCD or 100 Euro, bearing in mind that the original price is not consequential to this explanation.
From that 200 CCD or 100 Euro, I will get 180 CCD or 90 Euro
We have set it at 50%, but bear in mind that you want to make this as attractive as possible for buyers to be able to sell your work on the secondary market and still make a decent percentage of the sale.
Launchpad is available only for single fixed price NFT, that are not minted. One type of blockchain for tokens can be used inside one launchpad. Token can belong to one launchpad.
A User uploads zip-archive with necessary data: CSV file and folder with images.
NFT images and previews should be in a folder named "assets".
CSV file has to be named "info.csv". It must contain the following data:
NFT name;
NFT description;
preview file name (the same as in folder);
nft file name (the same as in folder).
File content must be comma separated.
First line has to contain columns names like: “name,description,preview file name,nft file name”. Next lines have to contain data specified above regarding NFTs in Launchpad.
You can use our template to form appropriate file for NFT bulk uploading. Zip-archive can be up to 1GB.
We offer support for CryptoX and MetaMask wallets. NOTE CryptoX desktop app is not available yet.
At this stage, we will only offer support for CryptoX wallet mobile application. NOTE desktop app is not available yet.
CryptoX
Please click on the following links:

Android - https://play.google.com/store/apps/details?id=com.pioneeringtechventures.wallet
MetaMask
Please click on the following link:
You can connect wallet on Spaceseven:
on header
or by choosing "Manage wallets" option
Once your wallet has been connected, you can see the wallet address in “Manage wallets” menu.
Install MetaMask on your device or MetaMask browser extension.
After installing the MetaMask wallet, you need to create an account.
Then you can connect wallet on Spaceseven:
on header
or by choosing "Manage wallets" option
Once your wallet has been connected, you can see the wallet address in “Manage wallets” menu.
Currently, there is a minimum threshold due to the way the network fee is calculated on the Concordium blockchain. The current amount required is 10CCD. This might change due to the price fluctuations of CCD.
CryptoX:
Spaceseven NFT will appear automatically in CryptoX wallet in correspondent folder. If you need to synchronize your NFTs with another marketplace, please follow next guide:
MetaMask:
Please, follow the instructions.
Introduction
To enable integration for web application with Concordium blockchain, you need to develop some integration flows.
Components, that required to be developed:
Frontend integration for web-to-wallet interaction
WebSockets bridge as transport for message with transaction parameters
Backend API for wallet, if you need advanced functions for NFT
Backend - Concordium synchronization driver
Smartcontracts
Note that links contain files with documentation regarding these components.
Concordium Web Bridge
To integrate Frontend and Wallet, you need to setup WebBridge. See detailed documentation here .
Docker image need to be requested from developer.
To develop Web to wallet interaction, you need to send transactions, which Wallet user will sign and send to blockchain.
Guideline, how to prepare smartcontract transaction.Backend API for wallet
API to show user NFT in wallet.
Backend - Concordium synchronization
To be able to get actual state for smartcontract, you need:
setup Concordium node
configure Transaction Summary logs collector
catch events for your smartcontract
decode events, according to event structure with same rules, as encoding transaction parameters (encoding rules and examples described in “Concordium-web-to_wallet-integration-protocol”)
update Backend database/storage with recognized event content
Smartcontracts
Your smartcontract, that deployed to Concordium blockchain, must generate Log Events with content, enough to synchronize backend data and blockchain smartcontract state data.
