# Library Modules

The library modules are divided into three categories (detailed below), each indicating the purpose, responsibility, and scope of the modules inside.

# Core

Core modules contain the baseline logic and functionality to build and run the application.

# Modules

• account - Manages the accounts of a profile
• app - Application configuration, setup, settings, etc.
• error - Generic code for building domain-specific errors
• i18n - Logic related to internationalization, languages, locales, etc.
• ledger - Code related to Ledger Nano profiles and devices
• network - Client options and node configuration, protocol settings, etc.
• nft - Managing NFTs, e.g. claiming, burning, transferring
• profile - General application logic to support profiles
• profile-manager - Library-related logic for managing and interacting with profiles
• router - Manage application views and flows
• stronghold - Code for Stronghold operations, utils, constants, etc. for software profiles
• token - Deals with tokens, metadata, conversion rates, registry, etc.
• utils - Useful and generic functions, e.g. formatting strings, converting units

# Rules

• MAY import code from other core modules
• MAY NOT import code from context or auxiliary modules

# Contexts

Context modules contain the logic specific to an area of the application.

# Modules

• collectibles - managing or viewing an account's NFTs
• developer - using developer tools to make lives easier
• onboarding - creating or restoring a profile or initial app setup
• settings - changing configuration of the app, profile, network, etc.
• staking - staking tokens to receive more tokens
• governance - using tokens to cast votes for community proposals
• wallet - sending or receiving coins and tokens, i.e. asset management

# Rules

• MAY import code from core and auxiliary modules
• SHOULD NOT import code from other context modules

# Auxiliary

Auxiliary modules are non-essential pieces of code that help support the application.

# Modules

• deep-link - parsing of deep links
• notification - managing notifications (both toast and system)
• popup - facilitates opening and closing of a popup
• wordlists - lists of the 2,048 words allowed in BIP39 (currently only English)

# Rules

• MAY NOT import code from context modules
• SHOULD NOT import code from other auxiliary modules
