This is an article on how to send Flash cryptocurrency, and also I have a question, This is my Python code, and the situation is as follows

1. A smart contract is generated
2. The transaction is sent
3. The blocks confirm
4. Gas fees are charged

But this is not placed in wallets

Does anyone know what could be the reason?
