This article describes how to create/restore a wallet.

Create Wallet

Creating Wallet

If you don't have a wallet, you can create a new one with the parameters 'wallet name' and 'wallet password'

• Wallet password can only be a "6-digit string of integers".

• A user can only create one wallet.

let walletId: Int = try await fncyWallet.makeWallet(
walletNm: "wallet name", 
pinNumber : "wallet password" // A 6-digit string of integers
)

Setting Wallet Restore Questions/Answers

If a user loses the password to the wallet, the assets in that wallet are lost forever.

However, if a user has registered a wallet restore question/answer, users can recover their wallet using that answer as a recovery key.

Requesting List of Wallet Restore Questions

The recovery key for restoring your wallet is a pair of selected questions and answers.

First, select a restore question by requesting for a list of questions to choose from.

let array: [FncyQuestion] = try await fncyWallet.getQuestionList(
pageNo: 1,
pageSize: 20
)

wid: wid, //If makeWallet() succeeds, wid is returned in the result.
questionSeq: questionSeq, //user-selected seq from the list of questions returned by getQuesetionList()
