Chapter 5: Integrating Wallet and sCrypt Service

1. Importing Dependencies:

  • The file opens with imports, including React, Material-UI components, and essential libraries like scrypt-ts.

2. Defining Constants and Utilities:

  • We define a constant, contract_id, representing the unique identifier of a deployed voting contract.
const contract_id = { /** The deployment transaction id */ txId: "5f88721569a223b0d08795328fe45a60723d6a4e5522df743998634b68b9b617", /** The output index */ outputIndex: 0, };

and a utility function, byteString2utf8, which converts ByteStrings to UTF-8 format (it converts the candidate name from bytestring to string UTF-8 format).


3. Enumerating Wallet Types:

  • The WalletType enum is declared, providing a structured representation of different wallet options which voter can easily choose from.
enum WalletType { PANDA = "panda", TAAL = "taal", Sensilet = "sensilet", }

4. Creating the Modal Component:

  • The Modal component introduces a way for users to connect their wallets. It features a button to initiate the connection process and a popup offering multiple wallet choices (Panda, Taal and Sensilet).

5. Accessing Wallet:

  • You can can easily have a clear display of voters wallet information, including address and balance.
const address = await signer.getDefaultAddress();

6. Main App Component (App):

  • Using the useEffect hook, it fetches voting contract information and sets up subscriptions for real-time updates.
  • It also manages state, incorporating functions for connecting wallets, logging out, and casting votes.
  • The voting table, adorned with images of iPhone and Android, allows voters to engage in the voting process.
  • Employs Material-UI Snackbar components to deliver user-friendly error and success messages.

Put it to Test

  • Get Address and balance from the connected wallet.
  • Declare an enum for panda, sensilet and taal wallets.
