Creation of the Switch Program
With the preliminary setup prepared for the switch course of, you need to create the switch program. You may start the method by opening the ‘lib.rs’ to delete the starter code. After you’ve got a clean slate, you can begin creating this system. The method of Anchor SPL token switch would begin with importing the essential dependencies. It is best to add the next on the highest of the file for importing the dependencies.
use anchor_lang::prelude::*;
use anchor_spl::token::{self, Token, TokenAccount, Switch as SplTransfer};
use solana_program::system_instruction;
declare_id!(“11111111111111111111111111111111”);
The imported dependencies will allow you to use the Anchor framework, the system program, and the SPL token program. As well as, Solana Playground would additionally mechanically replace the ‘declare_id!’ upon deploying this system.
Creating the SOL Switch Perform
You may switch SOL utilizing Anchor by making a perform for a similar. The switch perform would require a transparent definition of a struct. You may add the next code to this system.
#[derive(Accounts)]
pub struct TransferLamports<‘information> {
#[account(mut)]
pub from: Signer<‘information>,
#[account(mut)]
pub to: AccountInfo<‘information>,
pub system_program: Program<‘information, System>,
}
The struct supplies the definition of the ‘from’ account for signing the transaction and transferring SOL to the ‘to’ account. As well as, the system program may also help in managing the switch. You could observe that the ‘#[account (mut)]’ attribute would showcase this system would work on modifying the account. Within the subsequent step to switch SOL token, you need to create the perform that might be liable for managing the switch. Here’s a snippet which you can add to this system.
#[program]
pub mod solana_lamport_transfer {
use tremendous::*;
pub fn transfer_lamports(ctx: Context<TransferLamports>, quantity: u64) -> End result<()> {
let from_account = &ctx.accounts.from;
let to_account = &ctx.accounts.to;
// Create the switch instruction
let transfer_instruction = system_instruction::switch(from_account.key, to_account.key, quantity);
// Invoke the switch instruction
anchor_lang::solana_program::program::invoke_signed(
&transfer_instruction,
&[
from_account.to_account_info(),
to_account.clone(),
ctx.accounts.system_program.to_account_info(),
],
&[],
)?;
Okay(())
}
}
Right here is an evidence of the completely different points of the snippet.
The ‘#[program]’ attribute specifies that the module is an Anchor program. It helps in producing the boilerplate required for outlining the entry level of this system. It additionally works for automated administration of account deserialization and validation.
The ‘solana_lamport_transfer’ module helps in importing the necessary gadgets from the mother or father module by leveraging ‘use tremendous::*;’.
The ‘transfer_lamports’ perform receives an ‘quantity’ and ‘Context’ because the arguments. ‘Context’ argument contains the account info required for the transaction. However, the ‘quantity’ specifies the variety of lamports or SOL tokens you wish to switch.
You would additionally discover how the snippet helps in creating references to the ‘to_account’ and ‘from_account’ from the context. These references would play an important function within the switch.
You may as well discover the ‘system_instruction: :switch’ perform as a necessary instrument for making a switch perform. The switch perform takes the general public key of the ‘from_account’ and the ‘to_account’ alongside the ‘quantity’ that you simply wish to ship because the arguments.
You’d additionally want the ‘anchor_lang::solana_program::program::invoke_signed’ perform for invoking the switch perform. It makes use of the transaction signer or the ‘from_account’ by taking the switch instruction, which is an array of account info. The account info is derived from the ‘system_program,’ ‘from_account,’ and ‘to_account.’ As well as, it additionally delivers an empty array for signers.
Lastly, the ‘transfer_lamports’ perform would return the worth ‘Okay(())’ for showcasing a profitable execution. You may guarantee performance of the switch perform by clicking on the ‘Construct’ button or by typing the command ‘anchor construct’ within the terminal.

Creating the Perform for Transferring SPL Tokens
The subsequent spotlight in a information to switch SOL and SPL tokens utilizing Anchor focuses on making a perform for transferring SPL tokens. To begin with, you need to create a brand new context for the perform. It is best to add the next snippet to your program throughout the ‘TransferLamports’ struct.
#[derive(Accounts)]
pub struct TransferSpl<‘information> {
pub from: Signer<‘information>,
#[account(mut)]
pub from_ata: Account<‘information, TokenAccount>,
#[account(mut)]
pub to_ata: Account<‘information, TokenAccount>,
pub token_program: Program<‘information, Token>,
}
The struct would want the ‘from’ pockets, the token program, and ATA of the ‘from’ pockets and the ‘to’ pockets. You wouldn’t require the first account of the vacation spot pockets, as it could stay unchanged. You may add the next perform within the ‘transfer_lamports’ instruction.
pub fn transfer_spl_tokens(ctx: Context<TransferSpl>, quantity: u64) -> End result<()> {
let vacation spot = &ctx.accounts.to_ata;
let supply = &ctx.accounts.from_ata;
let token_program = &ctx.accounts.token_program;
let authority = &ctx.accounts.from;
// Switch tokens from taker to initializer
let cpi_accounts = SplTransfer {
from: supply.to_account_info().clone(),
to: vacation spot.to_account_info().clone(),
authority: authority.to_account_info().clone(),
};
let cpi_program = token_program.to_account_info();
token::switch(
CpiContext::new(cpi_program, cpi_accounts),
quantity)?;
Okay(())
}
Here’s a breakdown of the necessary parts of the perform.
‘transfer_spl_tokens’ perform receives an ‘quantity’ and ‘Context’ because the arguments. The ‘TransferSpl’ context contains the account info required for the transaction for transferring SOL tokens.
The Anchor SPL token switch perform additionally contains creating references to the ‘authority,’ ‘vacation spot,’ ‘token_program,’ and ‘supply’ from the context. The variables function representatives of the signer’s pockets, vacation spot ATA, token program, and supply ATA, respectively.
You also needs to discover the ‘SplTransfer’ struct that features account info of ‘authority,’ ‘supply,’ and ‘vacation spot.’ The struct would offer account info once you make a cross-program invocation to the Anchor SPL token program.
Additionally it is necessary to notice the usage of a brand new ‘CpiContext’ for calling the ‘token::switch’ perform. The ‘CpiContext’ makes use of the ‘cpi_program,’ ‘quantity,’ and ‘cpi_accounts’ within the perform that performs the precise switch of tokens between specified ATAs.
Lastly, you may return an ‘Okay(())’ to point profitable execution. Subsequently, you may construct this system once more and examine whether or not it really works correctly by clicking on ‘Construct’ choice or coming into the command ‘anchor construct’ within the terminal.
