solpyb 0.0.1

Pythonic Bridge to Solana Programs

solpyb

Pythonic Bridge to Solana Programs.

Overview

The project simplifies executing and getting responses from Solana Programs (a.k.a Smart Contracts), that are running on the Solana Blockchain.

Setup

pip install solpyb

A Simple Example

    from solpyb import SolBase, load_wallet


    class MyProgram(SolBase):
        slope: float
        intercept: float

    contract = MyProgram(
        program_id="64ZdvpvU73ig1NVd36xNGqpy5JyAN2kCnVoF7M4wJ53e", payer=load_wallet()
    )
    if contract([10, 5, 20, 7, 30, 8, 40, 12, 50, 20, 60, 15]):
        print(f"slope: {contract.slope} intercept {contract.intercept}")

(This script is complete, it should run "as is")

What's going on here:

• "64ZdvpvU73ig1NVd36xNGqpy5JyAN2kCnVoF7M4wJ53e" is a Solana Program (a.k.a Smart Contract) that performs a Linear regression on set of points and returns the slope and intercept as floats.
• load_wallet() loads the default wallet keys (.config/solana/id.json), as the payer for the transaction.
• MyProgram class implement a Pythonic wrapper class. Calling the call creates a transaction on chain and result is returned,
• SolBase populates slope and intercept with the values returned from the Blockchain.
