Solana: Add instructions to versioned transactions
Adding instructions to transactions with version on Solana
Version transactions allow you to add additional information to your transactions, which makes it easier to manage complex data in your smart contracts. However, when working with transactions with version, you must be careful not to enter errors or inconsistencies.
In this article, we will show you how to add instructions to a transaction with version on Solana using the solar-program and module@solana/program/script.
Premise
Before you start, make sure that you have installed the necessary libraries:
Bash
NPM Installation @solar-program/solar-inscription-program
or
Bash
Add Fire @Solana-Program/Solana-Script-Program
Transaction Code initially with instructions
JavaScript
const script = requires ('@solarprogram/script');
// define a function to generate instructions for the transaction
Async function generation of async (
payload,
userpublickey
) {
// Create a new instruction that includes the User's Cot and Public Key
Instructions Const = [
Script instructor ({
Name: "Quotresponse",
Args: [Payload.quotresponse],
}),
Script instructor ({
Name: "Userpublickey",
Args: [Userpublickey],
}),
];
return {instructions};
}
// create a new transaction that includes the instructions generated
Async Createtransction function (
payload,
userpublickey
) {
consist transaction = await script.createtransction (
{
Frompubkey: Userpublickey,
Sum: useful task.amount,
Scriptlimit: TRUE, // activate the version
},
Generateinstructions (useful task, userpublickey)
);
return transaction;
}
// Example of use:
consists useful = {
CotAGeresponse: "
The amount: 10n,
};
Const userpublickey = 'your_user_public_key_re';
Createtransction (useful task, userpublickey) .Then ((transaction) => {
console.log (transaction);
}). Catch ((error) => {
console.error (error);
});
How works works
In this example, we define a functionGenerate Instructions that take the useful task of the transaction and the user’s public key as arguments. This function creates two new instructions: one for the quotation response and another for the user’s public key.
Then we create a new transaction using the script.
The “Scriptlimit” option is set on TRUE, which allows the transaction version. This means that Solana will store several versions of the history of transactions, each containing the same instructions, but potentially with different values for the response of the quote or the public key.
best practices
When you work with transactions with version:
- Always use
scriptlimite with TRUE 'to activate the version.
- Use a consistent name convention for your instructions (for example,quilsponse
and Userpublickey).
- Keep the instruction data safe and do not share them publicly.
- Be aware of the potential impact on scalability and performance when you store several transaction versions.
By following these guidelines, you can effectively use version transactions to manage complex data in your smart contracts.
