I can provide an article on how to merge two transaction instructions in a solar transaction using Python.
Merge transaction instructions in Solana
When working with transactions in the Solana block chain, it is essential to understand how to combine multiple requests for instructions in a single transaction. This is crucial for the efficient and safe execution of complex transactions. In this article, we will explore how to merge two transaction instructions into a transaction using Python.
PREVIOUS REQUIREMENTS
Before immersing yourself in the code, be sure to have the following:
- A sole node (for example, solana cli or a local development environment)
- The
solana-programlibrary installed (pip install Solana-Program)
- Familiarity with the set of instructions from Solana and its various types
Understand the transaction instructions
In Solana, a transaction consists of multiple instructions that carry out several operations. Each instruction is represented as an object that contains relevant information, such as the identification of the program, calculate the budget instructions and more.
For this example, we will use the ‘Solana-Program’ library to create two separate transactions with different instructions. Then we will merge these transactions into a single transaction using Python.
Merge transactions in Solana using Python
« Python
Import Solana_program
Defines initial transactions as objects similar to dictionary
instruction1 = {
‘Program_id’: ‘My_token_program’,
‘Compute_budget’: [{‘program_id’: ‘my_swap_program’, ‘args’: [‘token_1’]}, {‘program_id’: ‘my_other_Swap_program’, ‘args’: [‘token_2’]}] ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,
‘Payo_info’: Solana_programpaymentinfo (
1000,
payment amount in the base unit (for example, Sol)
10,
payment token
solana_programpaymenttype (
1,
Type of payment (for example, payment or transfer)
0.01
payment rate
)
)
}
instruction2 = {
‘Program_id’: ‘My_swap_program’,
‘Compute_budget’: [{‘Program_id’: ‘My_other_swap_program’, ‘args’: [‘token_2’]}],
‘Payo_info’: Solana_programpaymentinfo (
1000,
payment amount in the base unit (for example, Sol)

0.01

)
)
}
Fuster transactions into a single transaction using the integrated functions of Python
Def merge_transactions (transaction1, transaction2):
Create a new transaction object
transaction = solana_program.transaction (
program_id = transaction1 [‘program_id’],
Accounts = [{
‘Account_id’: ‘m’,
sender account id
‘Key’: Solana_programkey (
0,
‘metro’,
1,
key version (for example, 1 or 2)
‘metro’
)
}],
programs = [transaction1 [‘program_id’], transaction2 [‘program_id’]]
)
Combine the two transactions in a
combined_transaction = solana_program.transaction (
program_id = transaction1 [‘program_id’],
Accounts = [

‘Account_id’:
‘Key’: Solana_programkey (
