🔧 API Reference

Core Interfaces

Web3 Entity Types

Web3Entity

Purpose: Represents a blockchain wallet entity with balance information
Properties: walletId, publicKey, balance
Usage: Wallet authentication and token balance tracking

ITokenGateEntity

Purpose: Token balance entry for access control
Properties: token_id, amount, serial_number (optional)
Usage: Token-based authentication and authorization

Configuration Types

_IUtility

Purpose: Network utility token interface
Properties: name, id, treasury, decimals
Usage: Utility token definitions and management

_IOptions

Purpose: Authentication configuration interface
Properties: redis, jwt, cookieOptions, operator, passport, appName

Token Gate Types

_IRole - Role-based access control interface_IMetadata - Token metadata interface for enriched information_IProperties - Token properties for subscription plans and periodicity_ITokenGateOptions - Configuration options for token gate behavior

Runtime Models

All interfaces have corresponding model classes with validation:

Web3EntityModel - Implements Web3Entity with validation
TokenGateEntity - Implements ITokenGateEntity with metadata
_Utility - Implements _IUtility with runtime validation
