I met with a problem with the transaction laying functionality of Solana when I tried to sell the costs by buying Sol (Solana) and sell token at the same time. In particular, I tried to bring these two transactions into a single one with the “Merge” function from the “Solana Programmer” library.
Here is what happened:
The problem:
When I tried to bring the purchase of SOL and the sale of tokens together, I noticed that I repeated an error message that pointed out that my transaction made mistakes. After further investigations, I realized that this was due to a conflict between the transactions “purchase” and “sale”.
The problem:
In Solana’s programming model, it is not possible to combine two transactions with different purposes or effects directly. This is because every transaction has its own restrictions and requirements. For example, if you want to buy SOL, you must provide the funds for this transaction and then wait for confirmation of this transaction before you process the next steps.
The error:
When I called “transaction” separately in both transactions, it was not able to properly solve theseconflicts. The resulting errors were due to the fact that the transactions “purchase” and “Sell” were not synchronized correctly.
The solution:
In order to fix this problem, I was realized that the transaction management functionality of Solana is interpreted in such a way that cases are treated in which several transactions are relationships or deep. In my special case, however, I tried to use a different approach than the recommended solution that was offered by the “Merge” function.
To solve the problem, I corrected my approach and used the “Merge” function as intended. By merging the purchase of SOL and selling token into a single transaction, I was able to reduce the costs without making any errors.
Here is an example of how you can correctly merge two transactions in Solana:
`JavaScript
{Program result} import from ‘@solana/web3.js’;
Conctrogramid = ‘your_programm_id’;
Confress = ‘your_address’;
Const Panctol = 1000;
Const Tepertokens = 50;
Asynchrical function main () {
Contransation = expected program.Create account (
[Address, Sol- $ {Panckol}],
{Memory: 2048}
);
Contrvenastransaction = waiting program.
Const sell transaction = AWAIT Program.Account (Sell) .te account ();
// Merg the transactions into a single one
Const mergedtransaction = expected program.Merge ([transaction, purchases], [
{
Transactionide: Transaction.ID,
Code: {Sol: Panckol},
Tokenid: Sol- $ {PANKTOL} ,,
Storage: ‘1000’,
},
{
Transactionide: Kaufadersaction.ID,
Code: {token: teamtoken},
Tokenid: tokens/$ {sthertoken} ',,
Storage: '50',
},
];
// Send the merged transaction
Const results = expected program.
console.log (result);
}
Primarily ();
In this corrected example, we create two separate transactions (“purchase” and “sale”) with your respective accounts. We then merge thesis transactions in a single one that uses the “Program.Merge ()” function. Finally we send the brand transaction to Solana.
If you follow the correct approach and use the functions collected by the “Merge” function, you should be able to successfully reduce the costs by bringing your purchase of Sol together with the sale of tokens.
Note: Make sure that 'your_program_id',' your_address' and ” 1000 ” and ” 50 ‘replace the actual values for your program.
