## Overview

Programmable Wallets Web SDK secures the process when users input their secret data, for example, PIN code and recovery questions. It also has various interfaces to interact with the [W3S APIs](https://developers.circle.com/w3s/reference/createuserwithpinchallenge) as in wallet creation, transaction initiation, also sign message (EIP-191) and sign typed-data (EIP-712) via the `challengeId`.

## Enums

Enumerates the types of challenges supported.

```typescript
enum ChallengeType {
  INITIALIZE,

  ACCELERATE_TRANSACTION,
  CANCEL_TRANSACTION,
  CONTRACT_EXECUTION,
  SIGN_MESSAGE,
  SIGN_TYPEDDATA,
  UNKNOWN,
}
```

### ChallengeStatus
