AdiWallet - simple NFT wallet

This is a console application that acts as an NFT wallet.

• You run the app which receives some subset of transactions, and processes them in such a way that enables the program to answer questions about NFT ownership. -The program executes only a single command each time it is run, and will persist state between runs.

Commands the program supports :

• running transaction batch from a json file
• running transaction batch inline (single or array of transactions)
• reset wallet
• information about a NFT
• information about a Wallet For more info about the specifications check out the doc here

Domain Schema

Notes:

• I have made heavy usage of a functional library Louthy - functional programming library for C# in order to make usage of Railway Programming (shortcircuit the flow at first error)

• Project structure

  • src:
    • AdiWallet.App - the console application
    • AdiWallet.Services - the place where logic logic resides
    • AdiWallet.Domain - the place where the domain model is placed ( all domain objects)
      • Commands - NftInfo, WalletInfo, Reset, ReadFile , ReadInline
      • Messages - Burn, Mint ,Transfer
      • Domain objects - Wallet , NFT , AppState (this one holds the state of the app and gets flushed to disk at the end of the program)
  • tests
    • AdiWallet.Tests - contains XUnit tests for most of the logic
      • tests for deserializing the messages
      • tests for running one message , a batch of messages
      • tests for the other commands , and testing if the resulting state written on disk is right

Setting up:

• Windows:
  • dotnet publish -c Release -r win10-x64 -o

Go to the [target-folder] and open a Command Prompt terminal

Run : AdiWallet.App.exe [arguments]

Example of running the program with some commands:

`AdiWallet.App.exe --nft somenft`

`AdiWallet.App.exe --wallet somewallet`

`AdiWallet.App.exe --read-file myfile.json`

`AdiWallet.App.exe --read-inline "{\"Type\": \"Mint\", \"TokenId\": \"ab\", \"Address\": \"adi\"},{\"Type\": \"Transfer\", \"From\": \"adi\",\"To\": \"dan\", \"TokenId\": \"ab\"},{\"Type\": \"Burn\", \"TokenId\": \"ab\"}]"`

`AdiWallet.App.exe reset`

The project contains unit tests which can be run by going in the root directory of the source folder and running :

dotnet test
