Python SDK for Casper 2.0

A Python Software Development Kit (SDK) for interacting with the Casper 2.0 blockchain network.

Overview

This SDK provides a comprehensive set of tools and utilities for developing applications on the Casper blockchain. It includes support for various CL (Casper) value types, transaction handling, and deployment management.

Features

• CL Value Type Support
• Transaction Management
• Deploy Operations
• Comprehensive Testing Suite

Usage Examples

CL Value Types

CLMap

# Create a map with a key-value pair
value = CLMap({CLU8(3): CLOption(CLString("Jim"))})

# Create an empty map with type information
empty_value = CLMap({}, {CLOption(CLU32(NoneHolder())): CLString(NoneHolder())})

CLList

# Create a list of optional strings
value = CLList([CLOption(CLString("hello")), CLOption(CLString("world"))])

# Create an empty list with type information
empty_value = CLList([], CLList([CLBool(NoneHolder())]))

CLOption

# Create an optional string
value = CLOption(CLString("hello"))

# Create an empty option with type information
empty_value = CLOption(CLString(NoneHolder()))

CLResult

# Create a successful result
ok_result = CLResult(
    Ok(CLOption(CLTuple2((CLString("hello"), CLU64(123))))),
    Err(CLU32(NoneHolder())),
    True
)

# Create an error result
err_result = CLResult(
    Ok(CLU32(NoneHolder())),
    Err(CLOption(CLTuple2((CLString("hello"), CLU64(123))))),
    False
)

CLTuple3

# Create a tuple with three values
value = CLTuple3((
    CLString("hello"),
    CLBool(True),
    CLURef("uref-fb6d7dd568bb45bd7433498c37fabf0883f8e5700c08a6541530d3425f66f17f-007")
))

Transaction Operations

For detailed examples of transaction operations, see the transaction examples.

Deploy Operations

For detailed examples of deploy operations, see the deploy examples.

Testing

The SDK includes a comprehensive test suite covering all CL value types and operations. Run the tests using:

python -m pytest packages/tests/
