Solana: how to close a PDA token account

Closing Public Data Account (PDA) to Solana: Step -by -Step Guide

SOLANA’s PDA Public Data Account (PDA) can be a little complicated, especially when you are not familiar with the anchor protocol and its nuances. In this article, we will translate you through the process of closing an account in PDA Token using the anchor SDK.

Prerequisites:

• You have a setting and working solana knot.

• You have an anchor portfolio installed on your Solana knot.

• You understand the basic concepts of public data account (PDA) and their use in the anchor protocol.

Step 1: Create PDA Account

First, create a new PDA account using an anchor SDK. This includes generating a new Mnemonic phrase and creating a new PDA account with a specific name, purpose and other metadata.

`Rust

Use Anchor_lang :: Account_Info;

Use Anchor_lang :: Entrypoint;

#[Entrypoint]

fn main () {

// Create a new PDA account

Let Mut Create_Pda = Accountinfo :: From_ID ("PDAACCOUNTID");

Create_pda.set_Name ("Mypdaaccountname"). set_purpose ("Somepurpose"). set_metadata (Vec! []);

Let _ = anchor_lang :: script :: create_pda (Create_pda) .signers ();

}

Step 2: Get PDA Account ID

You should then receive the PDA account identification number associated with your newly created account. You can do this by asking the database of Solana_Teken for all the accounts of markers that are part of the PDA.

`Rust

Use solana_sdk :: entrypoint :: get_pda_account_id;

// Get PDA Account ID

Let pda_account_id = get_pda_account_id ("some_mnemonic");

Step 3: Close PDA Account

You can now close the PDA account using an anchor SDK. You will need to go to the PDA account and the reason for closing the account.

`Rust

Use Anchor_lang :: Entrypoint;

#[Entrypoint]

fn main () {

// Get the status of the current account

Let Mut Account_state = Accountstate :: New ();

// Close the PDA account

Account_state.close_pda_Account (PDA_Account_ID, "DoseforClining" .to_string ()). Signers ();

}

Step 4: Update the marker account

Finally, you will need to update the marker account connected to your closed PDA account to reflect the new PDA status. This includes updating the “Solana_Teken” database with the new account ID.

`Rust

Use solana_sdk :: entrypoint :: adudl_taken_account;

// update the marker account

Let Mut Update_TeKen_Account = Accountupdate :: New (). set_pda_account_id (pda_account_id) .signers ();

adudl_taken_account.sign (& Account_state);

That’s it! With these steps, you should be able to close the PDA Token Account in Solana using the SDK anchor. Be sure to keep your mnemonic phrase and use it for this purpose only.

An example of using the case:

Here’s an example of how you can use the SDK anchor to close the PDA account in a larger application:

`Rust

Use Anchor_lang :: Account_Info;

Use Anchor_lang :: Entrypoint;

#[Entrypoint]

fn main () {

// Create a new PDA account

Let Mut Create_Pda = Accountinfo :: From_ID ("PDAACCOUNTID");

Create_pda.set_Name ("Mypdaaccountname"). set_purpose ("Somepurpose"). set_metadata (Vec! []);

Let _ = anchor_lang :: script :: create_pda (Create_pda) .signers ();

// Get the PDA account ID

Let pda_account_id = get_pda_account_id ("some_mnemonic");

// Close the PDA account

Account_state.close_pda_Account (PDA_Account_ID, "DoseforClining" .to_string ()). Signers ();

// Update the marker account

Adudl_TeKen_Account (

Accountupdate :: new (). Set_pda_account_id (pda_account_id) .signers (),

) .Sign (& Account_state);

}
