Solana: How to add priority norms to the CLMM position closure scenario?

I can help you with that. Here’s an article on adding priority fees to the CLMM script to close a Solana position:

Adding priority fees to CLMM scripts for closing positions on Solana

When trading on Solana, it is essential to effectively manage your slippage and expenses. One way to do this is by using priority fees, which allow you to charge a fee for each additional character in a close position. In this article, we will show you how to add priority fees to the CLMM (Close of Market) script to close a position on Solana.

Prerequisites

Before we get started, make sure you have the following:

• Solana node with CLI installed.

• Solana SDK version 1.12.0 or later.

• Basic understanding of Rust programming language and Solana blockchain concept.

Step 1: Create a new transaction script

To add priority fees to the CLMM closing position, you will need to create a new transaction script using the txscript framework. First install it via Cargo:

cargo add --dev txscript

Then create a new Rust file (e.g. priority_fees.clmm) and add the following code:

use solana_program::{
account_info::{ next_account_info, AccountInfo },
entrypoint::ProgramResult,
program_error::ProgramError,
pubkey::Pubkey,
};
use txscript::{TransactionScriptBuilder, InstructionId};
// Define the priority fee amount (in SPOR)
const PRIORITY_FEE_AMT: u64 = 0.0001;
fn main() -> ProgramResult {
// Create a new transaction script to build
let mut transaction_script_builder = TransactionScriptBuilder::new();
// Set the account information for the transaction
transaction_script_builder.set_account_info(
Pubkey::from_str("your_account_key"),
next_account_info(),
)?;
// Define a priority fee instruction
let priority_fee_instruction = InstructionId::new(
"priority_fees",
&["account", "field"],
&[PRIORITY_FEE_AMT],
);
// Set the priority fee amount (in SPOR)
transaction_script_builder.add_instruction(priority_fee_instruction)?;
// Set the script for closing the position
let close_position_script = TransactionScriptBuilder::new()
.set_account_info(
Pubkey::from_str("your_close_position_pubkey"),
next_account_info(),
)
.add_instruction(
ClosePositionInstructionId::new(
"close_position",
&["account", "field"],
&[0u64, 1u64],
),
);
// Set the priority fee amount (in SPOR)
close_position_script.add_instruction(
PriorityFeeInstructionId::new(
"priority_fee",
&["account", "field"],
&[PRIORITY_FEE_AMT],
),
)?;
// Set the transaction script

    transaction_script_builder.set_transaction_script(close_position_script)?;


    // Serialize and commit the transaction

    let serialized_transaction = transaction_script_builder.serialize()?;

    solana_program::program_account_info::AccountInfo::get(&serialized_transaction, "your_account_key")?;

    salt_program::program_resultat::Status::Success(());

}

This script creates a new transaction with an instruction to close a position that includes priority fees. PriorityFeeInstructionId is used to determine the priority fee amount.

2. step: add priority fees to the transaction

To add priority fees to a transaction, you will need to open a new account and set the priority fee amount. Here is the updated version of the script:

“`rust

// Create a new transaction script to build

let mut transaction_script_builder = TransactionScriptBuilder::new();

// Set the account information for the transaction

transaction_script_builder.set_account_info(

Pubkey::from_str(“your_account_key”),

next_account_info(),

)?
