Enhance Wallet Service with Support for Multiple Storage Drivers

[Ja7ad]

Description

The current wallet service supports only JSON files for reading and writing wallet details (e.g., addresses, information, and history). While functional, JSON files have limitations in handling larger datasets and can introduce complexity as the wallet scales.

Proposed Solution

To address these limitations, I propose implementing a storage driver system using polymorphism. This approach will enable the wallet service to support multiple internal and external storage drivers, such as JSON, SQLite, MySQL, and more.

Design Overview

We can introduce an abstraction layer with an interface for reading and writing wallet data. This interface will define methods for interacting with the wallet's vault. Below is an example of the proposed structure:

type Driver interface {
	Reader
	CreateValidator(ctx context.Context,label string) error
	CreateBlsAccount(ctx context.Context,label string) error
	// Additional methods as needed
}

type Reader interface {
	IsEncrypted(ctx context.Context) bool
	GetAddressInfo(ctx context.Context, addr string) (*AddressInfo, error)
	// Additional methods as needed
}
