Simplified Interface

The contract interface provides a set of package-level functions for basic contract operations:

// Storage operations
Get(key string, value interface{}) error
Set(key string, value interface{}) error
Delete(key string) error

// Utility functions
Log(event string, args ...interface{})
Sender() string
ContractAddress() string

Example: Counter Contract

A simple counter contract that demonstrates the use of the interface:

// Initialize the counter
Initialize(initialValue int64) error

// Increment the counter
Increment() error

// Decrement the counter
Decrement() error

// Get current value
GetValue() (int64, error)

// Reset counter to 0
Reset() error

Notes

• The interface is designed to be simple and focused on essential operations
• Storage operations use string keys and interface{} values for flexibility
• Logging and address functions are provided for convenience
