I can provide you with a Python example that does what you are asking for. This script uses the « pysolana » library to interact with the Solana blockchain.

Note:

You will need to install « pysolana » using pip « pip install pysolana ».

import os
import Pubkey from solana.publickey
from py_solana.api import account_info, system_info
def get_wallet_address():
"""
Returns the wallet address from a text file.
The first line of each line in the file must contain the wallet address,
separated by a newline.
:return: Solana's public key representing the wallet address.
"""
where open('wallet.txt', 'r') as f:
for line f:
if line.strip() != '':
returnline.strip()
raise ValueError("Wallet address not found in wallet.txt")
def get_tokens_with_balance(wallet_address):
"""
Returns a list of tokens purchased via the specified wallet address,
with a balance greater than 0.
:param wallet_address: Solana public key representing the wallet address.
:return: List of tuples, where each tuple contains:
- the name of the proxy (e.g. "DAI", "SOL")
- token symbol
- Amount purchased
- Current account balance
"""
tokens = []
to enter system_info.entries:
if record['id'] == wallet_address and record['balance'] > 0:
token_name, token_symbol = record['name'], record['symbol']
token_quantity = record.get('quantity', 1)
balance = record.get('balance', 0)
tokens.append((token_name, token_symbol, token_amount, balance))
return tokens
def get_pnl(tokens):
"""
Returns the profit and loss for each token.
:param tokens: A list of shells containing information about each token.

- token name (e.g. "DAI", "SOL")
- token symbol

"""
pnl = []
tokens in tokens:
win = token[2] * 10000 / token[1]
losses = -wins
pnl.append((token[0], token[1], win, loss))
return to the future
def main():
wallet_address = get_wallet_address()
try:
tokens = get_tokens_with_balance(wallet_address)
pnl = get_pnl(tokens)
print("Wallet address:", wallet_address)
marker pnl:
print(f"{token[0]} ({token[1]}) - {token[2]}x {token[3]} balance")
except ValueError like e:

main()

This script assumes that your wallet address is in the file « wallet.txt » in the same directory, and each line contains a single newline (\n`) and the wallet address on the following lines. For example:

ABC123
DEF456
GHI789

In this case, the script will output something like this:

Wallet address: ABC123
DAI (1x) - 1000 balance
SOL (2x) - 20,000 balance

Please note that this is a simplified example and does not take into account other factors that may affect the performance of your wallet, such as fuel costs or fluctuations. You may need to modify the script to suit your use case.

Also note that you need to replace « ABC123 » with your actual wallet address before running this script.
