General information

What is Chess Champ?

Chess Champ 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 or the Ethereum blockchain for taking their digital item to the public. Users could browse the Chess Champ marketplace for making bids and purchasing digital items. The items reside on the blockchain and are stored in your wallet when you purchase them.

What is an NFT?

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 (or another one dollar bill) 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 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

What are the platform fees charged and how does that work?

On the marketplace, a 10% platform fee will be deducted from all sales. This means that over and above the royalty fee set, a 10% platform fee will be deducted from the sale. This only affects the seller.

What is a Smart Contract?

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.

How does a smart contract work?

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 a blockchain 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.

Where am I able to view the NFT smart contract?

Currently we do not support the option to view our smart contracts.

Buying

What do I use for payment when buying on the Chess Champ?

You will need to connect your crypto wallet to buy an NFT on the Chess Champ marketplace. After connecting your wallet you can choose to buy NFTs with crypto or credit card. After the payment is completed, the NFT will be automatically transferred to your wallet.

How can I purchase a NFT on an auction?

A user selects an NFT that is selling on an auction at the Marketplace storefront and clicks on a “Place a bid” button on the NFT details page to place a bid.
The platform checks if a user has populated all the required information in her user profile. If all fields have been populated, the platform initiates the transaction for the user to send the bid to the blockchain.
Seller approves the auction end which finalizes the auction: transfers the funds and changes the owner.
Upon expiration of the auction, the smart contract transfers the NFT to the new owner.

Selling

What is minting/tokenizing an NFT?

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.

Are NFTs refundable?

We are unable to issue refunds as transactions on the blockchain are irreversible. We have no ability to cancel, revert, or modify any transactions.

Can I select more than one category when minting?

Yes.

Now that I have made a purchase, where do I find my NFT?

The NFT will be available in your crypto wallet.

How do royalties work?

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

What is the cap of royalties allowed to be set?

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.

What are the conditions for using launchpad?

If you are interested in using our launchpad function, please send us an email at [email protected].

How can I upload NFT bulk?

User uploads zip-archive with necessary data: CSV file and folder with images. For more information on bulk uploads for our launchpads, send us an email at [email protected].

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).

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.

Integration information

How to add NFT to CryptoX?

How to integrate CryptoX wallet into your web app?

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.

API for wallet registration.

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.
