Creating a Python Script for the Solana Smart Contract
As a developer, creating a Python script to interact with your Solana smart contract can be a great way to automate tasks, test ideas, or even build custom integrations. In this article, we will provide a step-by-step guide on how to create a basic Python script using the solana-program
library that allows you to create accounts and demonstrate buy and sell options.
Prerequisites
- Make sure you have Solana installed on your machine (you can download it from the [official Solana website](
- Create a new Solana CLI project using the following command:
solana program init
This will create a new pubkey.json
file in the root directory of your project, which contains your public key.
Install the required libraries
To interact with your smart contract, you will need to install the following libraries:
solana-program
: This is the primary library for interacting with Solana contracts.
requests
(for sending HTTP requests)
You can install these libraries using pip:
pip install solana-program requests
Create a Python script
Open a new file in the root directory of your project and add the following code:
import os
from solana_program import account_info, program_error, pubkey
from solana_program.lib.utils import to_bytes
Set up your Solana CLI project configurationPROJECT_DIR = 'path/to/your/project'
ACCOUNT_KEY = 'pubkey'
Replace with your public key from the pubkey.json fileCLIPUBKEY = 'your_clipublickey'
def create_account():
"""Create a new account on the blockchain"""
try:
Create a new account_, _account_id, _program_id = account_info.get_account_info(
pubkey.to_bytes(ACCOUNT_KEY),
to_bytes(CLIPUBKEY)
)
print(f"Account created: {ACCOUNT_KEY}")
return account_id
except program_error.ProgramError as e:
raise e
def demo_buy_sell():
"""Demonstrate buy and sell options"""
Create a new accountaccount = create_account()
Add funds to the accounttry:
Send 100 tokens from your wallet to the account_, token_amount, _account_id = account_info.get_account_info(
pubkey.to_bytes(ACCOUNT_KEY),
to_bytes(CLIPUBKEY)
)
print(f"Funds added: {token_amount} tokens")
return account_id
except program_error.ProgramError like e:
raise e
def main():
try:
Create a new account and send fundsaccount = create_account()
demo_buy_sell()
Make an HTTP request to the Solana clusterresponse = requests.post(' accounts/0/xpub/your_account_key', json={'key': 'new_token'}, headers={'Content-Type': 'application/json'})
print(f"HTTP Response: {response.status_code}")
except program_error.ProgramError like e:
raise e
if __name__ == '__main__':
main()
Explanation
This Python script creates a new account in Solana blockchain using your public key from pubkey.json
. It then adds funds to the account, simulates a buy and sell transaction by creating an HTTP request to send tokens between accounts (you can replace 'your_account_key'
with your actual account ID), and prints the HTTP response code. Note that you will need to modify the account key and clipublickey variables to match your specific use case.
