5. Mint Assets

Register users

  • Before users can mint/collect assets and create projects on Zecrey, they must register as Zecrey users. Please follow this procedure.

  • Zecrey NFT Marketplace has set several default categories to divide the collections. When creating a collection, you must select between one of the categories.

Upload Media

  • Upload pictures

📚SDK REFERENCE

Example

package main

import (
   "fmt"
   "github.com/Zecrey-Labs/zecrey-marketplace-go-sdk/sdk"
)


func main() {
    filePath := "/Users/alice/Documents/20221112-142909.jpg"
    result, err := sdk.UploadMedia(filePath)
    if err != nil { panic(err) }
    
    data, _ := json.Marshal(result)    
    fmt.Println(string(data))
}

Example result

{
    "public_id":"collection/tsgqu4cgj57wrxncllky", //unique Id of the picture
    "url":"https://res.cloudinary.com/zecrey/image/upload/v1668506730/collection/tsgqu4cgj57wrxncllky.jpg" //link of the picture
}

Create a Collection

  • When minting an NFT, it will be identified in a collection to distinguish different styles or topics. Collections will be submitted to the L1 chain by Zecrey. All collections created through Zecrey will be searchable in the NFT Marketplace.

  • The transaction of creating a collection will be confirmed by Zecrey. Once Zecrey confirms this collection, it will be submitted to L1.

  • Parameters needed for creating a collection:

Mint NFT

  • Every account has a default collection ID. If the collection ID is not filled in, the NFT will be associated with the default collection ID = 0. Transaction of minting an NFT will be confirmed by Zecrey and once the NFT is confirmed, Zecrey will submit it to L1.

  • L2 allows the change of ownership for the NFT. However, the creator of the NFT will never change. Each time an NFT is transferred, the creator will receive a royalty, which is calculated by the NFT's TreasuryRate set by its creator.

📚SDK REFERENCE

  • Parameters needed for creating an NFT:

    Parameter

    Parameter usage and meaning

    Required or not

    accountName

    The account name used to initialize the client

    seed

    The user's L2 seed used to initialize the client

    NftUrl

    The logo image displayed for mobile users

    Name

    NFT name

    Description

    The description of the NFT, and filling in "-" is recommended if there is no description

    assetProperty

    Custom properties

    assetLevel

    Custom levels

    assetStats

    Custom stats

    TreasuryRate

    Creator royalties will be charged at this rate and the percentage will be in proportion to 10000 during NFT transactions. For example, filling in 50000 means the rate will be 5000/10000 % = 0.5%

  • Create an NFT with the name "Alice's BestNft"

    1. Initialize the client

    2. Use json Marshal to transform the properties, levels and stats into string type

    3. Create an NFT

Example

package main

import (
   "fmt"
   "github.com/Zecrey-Labs/zecrey-marketplace-go-sdk/sdk"

func main() {
        var CollectionId int64 = 15 //Get list of collections
