# solpyb

Pythonic Bridge to Solana Programs. Inspired by [Pydantic](https://pydantic-docs.helpmanual.io/)

## Overview

The project simplifies executing and getting responses from Solana Programs (a.k.a *Smart Contracts*), that are running on the Solana [Blockchain](https://solana.com/).

## Setup

`pip install solpyb`

## A Simple Example: Calculate *Linear Regression* on-chain

```python

import asyncio

from solpyb import SolBase, load_wallet

class MyProgram(SolBase):

    slope: float

    intercept: float

contract = MyProgram(

    program_id="64ZdvpvU73ig1NVd36xNGqpy5JyAN2kCnVoF7M4wJ53e", payer=load_wallet()

)

if asyncio.run(contract([10.5, 20.7, 30.8, 40.12, 50.20, 60.0])):

    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](https://en.wikipedia.org/wiki/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.
