I can help you with that. Here’s an article on the addition of priority fees to the CLMM Close Pool Script on Solane:
Adding fees for priority to the CLMM Close Script script on Solane
When trading with Solana, it is necessary to effectively manage your slip and cost. One way to do this is to use priority fees that allow you to charge a fee for each additional tick in a tight position. In this article, we’ll show you how to add priority fees to the CLMM script (near the market) in Solana.
assumptions
Before we start, make sure you have the following:
- Solana node with cli installed.
- Solana SDK version 1.12.0 or later.
- A basic understanding of the concepts of the rust programming language and concepts of Blockchain Solan.
Step 1: Create a new transaction script
To add priority fees to CLMM Close position, you will need to create a new transaction script using the TxScript crate. Install it first via cargo:
`Bash
COST Add -Dev Txscript
`
Next, create a new RUST file (eg Priority_fees.Clmm) and add the following code:
`rust
Use solan_program :: {
foreign_info :: {next_account_info, accountinfo},
EntryPoint :: Programresult,
Program_error :: Programmerrror,
PUBKEY :: PUBKEY,
};
Use TXSRIPT :: {transactionScriptbuilder, insuretide};
// Define the amount of the priority fee (in the dispute)
Const Priority_fee_amt: U64 = 0.0001;
Fn Main () -> ProgramResult {
// Create a new transaction script creator
Let Mut Transaction_Script_builder = TransactionScriptbuilder :: New ();
// Set up an account information for the transaction
transactions_script_builder.set_account_info (
PUBKEY :: From_sto (“Your_account_key”),
Next_Account_info (),
)?;
// Define the instructions for priority fees
Let Priority_fee_instruction = INSUNCHERID :: New (
“Priority_fees”,
& [“Account”, “Field”],
& [Priority_fee_amt],
);
// Determine the amount of the priority fee (in the dispute)
Transaction_Script_builder.add_instruction (priority_fee_instruction)?;
// Set the Close Pool script
Let Close_positics_script = transactionspriptbuilder :: new ()
.Set_account_info (
PUBKEY :: From_sto (“Your_close_positics_pubkey”),
Next_Account_info (),
)
.add_instruction (
Closepositioninstructionid :: New (
“Close_positics”,
& [“Account”, “Field”],
& [0u64, 1U64],
)
);
// Determine the amount of the priority fee (in the dispute)
Close_positics_script.add_instruction (
PriorityFeeinStructionid :: New (
“Priority_fee”,
& [“Account”, “Field”],
& [Priority_fee_amt],
)
)?;
// Set the transaction script
Transaction_Script_builder.set_transaction_script (Close_Post_Script)?;
// serialize and make a transaction
Let serialized_transaction = transaction_script_builder.serialize ()?;
Solan_program :: program_account_info :: Accountinfo :: Get (& serialized_transaction, “your_account_key”)?;
Solan_program :: program_result :: Status :: Success (());
}
`
This script creates a new transaction with an instruction of a close position that contains priority fees. “PriorityFeeinstructionid” is used to determine the amount of the priority fee.
Step 2: Add priority fees to transaction
To add priority fees to the transaction, you must create a new account and set the amount of priority fees. Here’s an updated version of the script:
`rust
// Create a new transaction script creator
Let Mut Transaction_Script_builder = TransactionScriptbuilder :: New ();
// Set up an account information for the transaction
transactions_script_builder.set_account_info (
PUBKEY :: From_sto (“Your_account_key”),
Next_Account_info (),
)?
