Add instructions to transactions with Solana version
Transactions with the version allow you to provide additional information to transactions, facilitating the processing of complex data in smart contracts. However, working with transactions with the version must be careful not to introduce errors or inconsistencies.
In this article, we will show you how to add instructions to a transaction with Solana version, using the “Solana Program” directory and the @@ solana/program/script module.
Prerequisites
Before we start, make sure you installed the necessary libraries:
`Bash
NPM Installation @Solana Program/Solana-Script-Program
`
or
`Bash
yarn add @Solana-program/Solana-script-program
`
Initial transaction code with instructions
`Javascript
Const script = required ('@Solanaprogram/script');
// Determine a feature to generate instructions for the transaction
Async function generation factors (
payload,
UserPublicKey
) {
// Create a new instruction that includes quotation and user public key
Const instructions = [
script instruction ({
Name: 'Quoteresponse',
Args: [Payload.quoteresponsse],
}),
script instruction ({
Name: 'UserPublicKey',
Args: [UserPublicKey],
}),
];
return {instructions};
}
// Create a new transaction that includes the instructions generated
Async function Createtransection (
payload,
UserPublicKey
) {
Const Transaction = Waiting for Script.createtransection (
{{
Frompubkey: UserPublicKey,
Amount: Useful burden.amount,
Scriptlimit: TRUE, // Enable the version
},
Generateinstructations (Useful load, userpublickey)
);
return transaction;
}
// using examples:
Const useful burden = {
Quoteresponsse: '
Amount: 10N,
};
CONST USERPUCKEY = 'Your_user_public_Key_here';
Createtransection (useful load, userpublickey) .Then ((transaction) => {{{
console.log (transaction);
}). catch ((error) => {{{
Console.Error (error);
});
How does it work
In this example, we define a “Generateinstruction” function that takes the useful burden of the transaction and the user public key. This feature creates two new instructions: one to answer the quote and the other to the user public key.
We then create a new transaction using the script.createtransection", giving an object with 'frompubkey',sum ‘andscriptlimit' options.
The "Scriptlimite" option is set to be true that allows the transaction version. This means that Solana stores several versions of the transaction history, each containing the same instructions, but potentially the quote response or the different values of the user public key.
The best exercises
If you work with transactions with version:
- Always use "scriptlimit" with "TRUE" to enable the version.
- Use a consistent naming convention for instructions (such asquoteresponsse
anduserpublickey`).
- Keep the instructions safely and do not share it publicly.
- Be aware of the potential effect on scalability and performance when storing several versions of transactions.
In keeping with these guidelines, you can effectively use the version of transactions with a version to manage complex data in smart contracts.
