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 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 make it easier 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 operate for a similar. The switch operate would require a transparent definition of a struct. You may add the next code to this system.
#[derive(Accounts)]
pub struct TransferLamports<'data> {
#[account(mut)]
pub from: Signer<'data>,
#[account(mut)]
pub to: AccountInfo<'data>,
pub system_program: Program<'data, System>,
}
The struct gives the definition of the ‘from’ account for signing the transaction and transferring SOL to the ‘to’ account. As well as, the system program will help in managing the switch. You need to be aware 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 operate that may be chargeable for managing the switch. Here’s a snippet 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 a proof of the totally different facets 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 computerized administration of account deserialization and validation.
The ‘solana_lamport_transfer’ module helps in importing the vital gadgets from the father or mother module by leveraging ‘use tremendous::*;’.
The ‘transfer_lamports’ operate receives an ‘quantity’ and ‘Context’ because the arguments. ‘Context’ argument contains the account info required for the transaction. Alternatively, the ‘quantity’ specifies the variety of lamports or SOL tokens you need to switch.
You might 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 position within the switch.
You can too discover the ‘system_instruction: :switch’ operate as an important instrument for making a switch operate. The switch operate takes the general public key of the ‘from_account’ and the ‘to_account’ alongside the ‘quantity’ that you simply need to ship because the arguments.
You’d additionally want the ‘anchor_lang::solana_program::program::invoke_signed’ operate for invoking the switch operate. 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’ operate would return the worth ‘Okay(())’ for showcasing a profitable execution. You may guarantee performance of the switch operate 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 operate for transferring SPL tokens. Initially, you need to create a brand new context for the operate. It is best to add the next snippet to your program throughout the ‘TransferLamports’ struct.
#[derive(Accounts)]
pub struct TransferSpl<'data> {
pub from: Signer<'data>,
#[account(mut)]
pub from_ata: Account<'data, TokenAccount>,
#[account(mut)]
pub to_ata: Account<'data, TokenAccount>,
pub token_program: Program<'data, 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 might stay unchanged. You may add the next operate 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 vital elements of the operate.
‘transfer_spl_tokens’ operate 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 operate 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 must also discover the ‘SplTransfer’ struct that features account info of ‘authority,’ ‘supply,’ and ‘vacation spot.’ The struct would offer account info if you make a cross-program invocation to the Anchor SPL token program.
It’s also vital to notice using a brand new ‘CpiContext’ for calling the ‘token::switch’ operate. The ‘CpiContext’ makes use of the ‘cpi_program,’ ‘quantity,’ and ‘cpi_accounts’ within the operate that performs the precise switch of tokens between specified ATAs.
Lastly, you possibly can return an ‘Okay(())’ to point profitable execution. Subsequently, you possibly can construct this system once more and examine whether or not it really works correctly by clicking on ‘Construct’ possibility or getting into the command ‘anchor construct’ within the terminal.
