I can provide you with an article on how to combine two transaction statements into one Solana transaction using Python.
Instructions for merging Solana transactions
When working with transactions in the Solana blockchain, it is important to understand how to combine several instruction requests into one transaction. This is crucial for the efficient and secure execution of complex transactions. In this article, we will look at how to combine two transactional statements into one transaction using Python.
Prerequisites
Before diving into the code, make sure you have the following:
- Solana node (eg Solana CLI or local development environment)
- The library
solana-programis installed (pip install solana-program)
- Getting to know the Solana instruction set and its different types
Understanding Transaction Instructions
In Solana, a transaction consists of several instructions that perform various operations. 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 merge these transactions into a single transaction using Python.
Merging transactions in Solana using Python
“ python
import solana_program
Define initial transactions as dictionary-like objects
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’]}],
‘payment_info’: solana_programPaymentInfo(
۱۰۰۰,
payment amount in base unit (eg SOL)
۱۰,
payment token
solana_programPaymentType(
۱,
type of payment (for example, payment or transfer)
۰.۰۱
payment percentage
)
)
}
instruction2 = {
‘program_id’: ‘my_swap_program’,
‘compute_budget’: [{‘program_id’: ‘my_other_swap_program’, ‘args’: [‘token_2’]}],
‘payment_info’: solana_programPaymentInfo(
۱۰۰۰,
payment amount in base unit (eg SOL)
۱۰,
payment token
solana_programPaymentType(
۱,
type of payment (for example, payment or transfer)
۰.۰۱
payment percentage
)
)
}
Combine transactions into one using built-in Python functions
def merge_transactions(transaction1, transaction2):
Create a new transaction object
transaction = solana_program.Transaction(
program_id=transaction1[‘program_id’],
account=[{
‘account_id’: ‘m’,
Sender’s account ID
‘key’: solana_programKey(
۰,
“m”,
۱,
key version (eg 1 or 2)
‘m’
)
}],
programs=[transaction1[‘program_id’], transaction2[‘program_id’]]
)
Combine two transactions into one
combined_transaction = solana_program.Transaction(
program_id=transaction1[‘program_id’],
account=[
{
‘account_id’: ‘combined_m’,
the sender’s account identifier
‘key’: solana_programKey(
۰,
‘combined_m’,
۱,
key version (eg 1 or 2)
‘combined_m’
)
},
{
‘account_id’: ‘m’,
Sender’s account ID
‘key’: solana_programKey(
۰,
“m”,
۱,
key version (eg
