I can provide you with an article on how to combine two transaction statements into a single Solana transaction using Python.
Combining Transaction Instructions in Solana
When working with transactions on the Solana blockchain, it is important to understand how to combine multiple instruction requests into a single transaction. This is essential for executing complex transactions efficiently and securely. In this article, we will cover how to combine two transaction statements into a single transaction using Python.
Prerequisites
Before diving into the code, make sure you have:
- A Solana node (e.g. Solana CLI or local development environment)
- The “solana-program” library installed (“pip install solana-program”)
- Familiarity with the Solana instruction set and its different types
Understanding Transaction Instructions
A Solana transaction consists of multiple instructions that perform different actions. Each instruction is represented as an object containing relevant information, such as the program identifier, instructions for calculating the budget, etc. d.
In this example, we will use the solana-program' library to create two separate transactions with different instructions. We will then combine these transactions into a single transaction using Python.
Merging Transactions in Solana Using Python
“ python
import solana_program
Define the initial transactions as dictionary-like objects
statement1 = {
‘program_id’: ‘my_token_program’,
‘compute_budget’: [{‘program_id’: ‘my_swap_program’, ‘args’: [‘token_1’]}, {‘program_id’: ‘my_other_swap_program’, ‘args’: [‘token_2’]}],
‘payment_info’: solana_programPaymentInfo(
1000,
payment amount in base unit (e.g. SOL)
10,
payment token
solana_programPaymentType(
1,
payment type (e.g. payment or transfer)
0.01
payment rate
)
)
}
statement2 = {
‘program_id’: ‘my_swap_program’,
‘compute_budget’: [{‘program_id’: ‘my_other_swap_program’, ‘args’: [‘token_2’]}],
‘payment_info’: solana_programPaymentInfo(
1000,
payment amount in base unit (e.g. SOL)
10,
payment token
solana_programPaymentType(
1,
payment type (e.g. payment or transfer)
0.01
payment rate
)
)
}
Merge transactions into a single transaction using built-in Python functions
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 identifier
‘key’: solana_programKey(
0,
“es”,
1,
key version (e.g. 1 or 2)
“es”
)
}],
programs=[transaction1[‘program_id’], transaction2[‘program_id’]]
)
Combine two transactions into one
combined_transaction = solana_program.Transaction(
program_id=transaction1[‘program_id’],
accounts=[
{
‘account_id’: ‘combined_m’,
sender account identifier
‘key’: solana_programKey(
0,
‘combined_m’,
1,
key version (e.g. 1 or 2)
‘combined_m’
)
},
{
‘account_id’: ‘m’,
sender account identifier
‘key’: solana_programKey(
0,
“es”,
1,
key version (e.g.
