I can provide you with an article on how to merge two transaction instructions into one transaction on Solana using Python.
Merging Transaction Instructions in Solana
When working with transactions on the Solana blockchain, it’s essential to understand how to combine multiple instruction requests into a single transaction. This is crucial for efficient and secure execution of complex transactions. In this article, we’ll explore how to merge two transaction instructions into one transaction using Python.
Prerequisites
Before diving into the code, ensure you have the following:
- A Solana node (e.g., Solana CLI or a local development environment)
- The
solana-programlibrary installed (pip install solana-program)
- Familiarity with Solana’s instruction set and its various types
Understanding Transaction Instructions
In Solana, a transaction consists of multiple instructions that perform various operations. Each instruction is represented as an object containing relevant information, such as the program ID, compute budget instructions, and more.
For this example, we’ll 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 the 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(
1000,
payment amount in the base unit (e.g., SOL)
10,
payment token
solana_programPaymentType(
1,
payment type (e.g., payment or transfer)
0.01
payment rate
)
)
}
instruction2 = {
‘program_id’: ‘my_swap_program’,
‘compute_budget’: [{‘program_id’: ‘my_other_swap_program’, ‘args’: [‘token_2’]}],
‘payment_info’: solana_programPaymentInfo(
1000,
payment amount in the base unit (e.g., SOL)
10,
payment token
solana_programPaymentType(
1,
payment type (e.g., payment or transfer)
0.01
payment rate
)
)
}
Merge the transactions into a single transaction using Python’s built-in 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 ID
‘key’: solana_programKey(
0,
‘m’,
1,
key version (e.g., 1 or 2)
‘m’
)
}],
programs=[transaction1[‘program_id’], transaction2[‘program_id’]]
)
Combine the two transactions into one
combined_transaction = solana_program.Transaction(
program_id=transaction1[‘program_id’],
accounts=[
{
‘account_id’: ‘combined_m’,
sender account ID
‘key’: solana_programKey(
0,
‘combined_m’,
1,
key version (e.g., 1 or 2)
‘combined_m’
)
},
{
‘account_id’: ‘m’,
sender account ID
‘key’: solana_programKey(
0,
‘m’,
1,
key version (e.g.
