B. Series Name The series name is extracted from Metadata Object (1.30.x). If the name length is too long then it has to be truncated. Field: base_uri —> name

Example:
"base_uri": "{"name":"Mint Bears Zeroth Run"}
In case, if the name cannot be extracted then Fall back to
"name": "Mint Bears Zero"

C. NFT Name The NFT name is extracted from NFT Object (1.31.x). Field: token_uri —> name

Example:
"name": "Mint Bears #0"
If cannot be extarcted then Fall back on
"symbol":"index"

D. View NFT Provide an option to view the NFT in detail.

There are alternate ways in implementing this option and based on the design suggestion the NFT detailed page view will be displayed. Any one of the following options can be implemented,

However, it should be a part of collection.

C. Display Name

• Few collections shall have a well defined display name. Field: token_uri —> name

• In case, if the name is not defined then it fall back to the Metadata object name. Field: base_uri —> name

6.2 Key Design Characteristics

The TradeHands Explorer Home page shall consider the following key design characteristics,

• Color Gradient

• Layering

• Transparency

• Content Flow

• Interactivity

• Modularization

A. Color Gradient

Blending of two or three colors across a block of space, a background, header text, or borders adds to the organic feel of the app.

The front page shall make use of color gradients where ever appropriate.

B. Layering

Layering shapes can help to show how objects relate to each other. Use of layering also signals to the user, the object hierarchy or order of events. Layering also makes the page feel more realistic.

The front page shall make use of shape layering to show object relationships, hierarchy, and/or order of events. Also incorporate drop shadows or similar techniques to help illustrate shape layering.

C. Transparency

The use of transparency when layering objects can produce a modern feel that doesn’t sacrifice the organic feel. Transparency is best used together with blur, parallax, colorization, or a combination of other techniques.

The front page shall make use of transparency, with or without related techniques, where ever appropriate.

D. Content Flow

The content flow is about providing quick and easy access to what users need, and it’s about delivering a story to the user. The main purpose of the content should be delivered early, the bulk of the content in the middle, and finishing up with detailed info, use-case specific functions, and solutions for edge cases. This can apply to all scales of content across the app (whole pages, user info, NFT info, a pop-up modal, etc.)

The front page shall begin with a highlight section. Followed by the introduction of new concepts to users from top to bottom, such as the following:

• The featured NFTs shall be displayed which showcase the brief description about it

• The NFT Collection are broad in scope that contain the NFTs.

• NFTs, on their own, are atomic which can exist independently of collections.

E. Interactivity

There should be a deep level of interaction between the user and the app. This creates a connection with the user.

The Front page shall provide an interactive approach to informational displays.

F. Modularization

The site admin shall have the privileges to categorize the sections as modules based on the requirement. The following privileges shall be given to site admin,

• An option to view both NFTs and event at the same section based on filters.

• To decide which section to appear based on required orders.

• To control the headings and sub-group of any section.

The site admin shall be responsible for specifying the headings and NFTs included in the section should be determined through some mechanism which has to determined (future scoped). The mechanism can be a configuration file, database call or some API call. Finally, different sections should be present in the configuration file and Home page should be able to display based on this configuration.

Example

The grouping should be based on below two category,

1. Featured Artworks - The list of artworks in the NFT collection.

2. Featured Events - The list of events available in the collection.

The collections shall be modularized based on the selection of the site admin. They can be defined as some of the examples stated below,

• Popular NFTs in past 7 days

• Top collections

• Most popular events

• Different groupings of NFTs

• NFTs with more value

7. Appendix A

Term	Meaning
FS	Functional Specification
NFT	Non-Fungible Token
SEO	Search Engine Optimization

A. NFT Object

An NFT object defines a specific, singular, issued, hold able, transferrable, and tradable NFT. It occupies the 1.31.x object space in the object database. An example NFT object is 1.31.7, which is the first of the "Mint Bears" series on the Mint test net.

The object has the following properties, which can be observed via get_objects call to an API node:

{
  "approved": "1.2.179",
  "approved_operators": [],
  "id": "1.31.7",
  "nft_metadata_id": "1.30.8",
  "owner": "1.2.179",
  "token_uri": "{\"name\":\"Mint Bears #0\",\"created_by\":\"Masha\",\"description\":\"Furry and fun MintBears! This is an early preliminary issuance of the Mint Bears. More to come?\",\"image\":\"ipfs://bafybeidbpxnhns73t2le244n3l73q4ex6o4edu32bqgp72toarr6a6ukim/0.png\",\"attributes\":[{\"trait_type\":\"Fur Color\",\"value\":\"Brown\"},{\"trait_type\":\"Eye Color\",\"value\":\"Blue\"}]}"
}

Points to Remember:

• The token_uri field is an open-ended string field, that can be populated with JSON-formatted text. The details page will attempt to interpret the JSON in order to extract things like image links and descriptive data. If this process fails, (e.g. if the field is NOT populated with valid JSON-formatted text, or if the schema is not understood by the interpreter), then fallbacks need to be assumed for the UI elements that draw from this data.

• Because the token_uri field is a text field, shown as a JSON object above, the quote characters are escaped. (i.e. \" is substituted for ".) However, the binary string data in the object contains " not \".

• For reference, an un-escaped, pretty-printed dump of the token_uri JSON-formatted objects would look like this:

{
  "name": "Mint Bears #0",
  "created_by": "Masha",
  "description": "Furry and fun MintBears! This is an early preliminary issuance of the Mint Bears. More to come?",
  "image": "ipfs://bafybeidbpxnhns73t2le244n3l73q4ex6o4edu32bqgp72toarr6a6ukim/0.png",
  "attributes": [
    {
      "trait_type": "Fur Color",
      "value": "Brown"
    },
    {
      "trait_type": "Eye Color",
      "value": "Blue"
    }
  ]
}

B. NFT Metadata Object

An NFT metadata object defines a collection of NFTs that share a common issuing account, series symbol, name, and contract rules. It occupies the 1.30.x object space in the database. The descriptive metadata issued is a JSON blob which can be optionally inserted into the token_uri field of NFT objects (1.31.x objects) to provide semantic or interpretive meaning to individual NFTs. This "metadata" can be a narrative-style description, artist, creator information, etc.,

The object has the following properties, which can be observed via get_objects call to an API node:

{
  "base_uri": "{\"name\":\"Mint Bears Zeroth Run\",\"created_by\":\"Masha\",\"description\":\"Furry and fun MintBears! This is an early preliminary issuance of the Mint Bears. More to come?\",\"base_uri\":\"ipfs://bafybeicym3epgdalnw6r3gns57njic57e34i4zn5jhg655zubdrwgxxise\"}",
  "id": "1.30.8",
  "is_sellable": true,
  "is_transferable": true,
  "max_supply": 1000,
  "name": "Mint Bears Zero",
  "owner": "1.2.179",
  "revenue_partner": "1.2.179",
  "revenue_split": 250,
  "symbol": "MINTBEARSZERO"
}

Points to remember:

• The owner of the metadata object can be thought of as the "issuer" of the NFTs in the collection. (In contrast to the owner of the 1.31.x object, which can be thought of as the "holder" of the specific issued NFT.)

• The metadata object determines permissions and contract terms (e.g. sellable, transferable, revenue split, etc.) of all NFTs issued under the same contract.

• The chain understands the symbol and token name which are defined for the series, and are not variable by individual NFT. However, NFTs may define, through their descriptive data, "display names" which can be displayed for the NFT name, series name, or artist.

• The NFT metadata object also has an arbitrary string field (base_uri) which can be packed with JSON-formatted text. This data can be thought to apply to the entire collection. Mostly the NFT Details Page won't concern itself with this data, except in areas where it describe the series to which the NFT belongs.
