SPL Token Helper Crate

Status: ✅ Initial Version Released ✅

This crate simplifies the process of creating SPL tokens on the Solana blockchain by providing a user-friendly abstraction layer. Our goal is to streamline the token creation process with minimal setup while also offering flexibility for advanced users. You can use the following functions:

mint_simple: Mint SPL tokens with associated metadata.
transfer_simple: Transfer SPL tokens between accounts.
burn_simple: Burn SPL tokens from an account.

Features

Easy SPL Token Creation: Quickly create and manage SPL tokens with metadata in just a few steps.
Manual Setup Options: Advanced users can manually configure token parameters and metadata through the provided functions.
Token Transfer Support: Transfer SPL tokens between accounts using a simplified interface.
Metadata Integration: Automatically creates token metadata using the mpl_token_metadata program, with support for custom metadata attributes like name, symbol, URI, and seller fees.
Token Burning: Burn SPL tokens from an account with ease.
Developer-Friendly: The crate is modular and well-documented, making it easy to integrate into existing Solana projects.

Usage

Minting Tokens with Metadata

The mint_simple function allows you to mint SPL tokens and automatically create the associated metadata.

use spl_token_helper::mint_simple;
use anchor_lang::solana_program::account_info::AccountInfo;

// Mint SPL tokens with metadata
let result = mint_simple(
    "TokenName".to_string(),
    "TKN".to_string(),
    "https://example.com/token-metadata".to_string(),
    500, // 5% seller fee
    payer_account_info,
    token_metadata_program_info,
    update_authority_info,
    metadata_account_info,
    mint_authority_info,
    system_program_info,
    rent_sysvar_info,
    token_program_info,
    mint_account_info,
    to_account_info,
    owner_account_info,
    &[&signer_seeds],
    1000 // Mint 1000 tokens
).unwrap();

Transferring SPL Tokens

The transfer_simple function lets you transfer SPL tokens between accounts using a minimal setup.

use spl_token_helper::transfer_simple;

// Transfer SPL tokens between accounts
let result = transfer_simple(
    mint_account_info,
    token_program_account_info,
    source_pubkey,
    destination_account_info,
    authority_account_info,
    500, // Transfer 500 tokens
    &[&signer_seeds],
).unwrap();

Burning SPL Tokens

The burn_simple function allows you to burn (destroy) SPL tokens from a specified account.

use spl_token_helper::burn_simple;

// Burn SPL tokens from an account
let result = burn_simple(
    mint_account_info,
    token_program_id,
    source_pubkey,
    authority_account_info,
    500, // Burn 500 tokens
    &[&signer_seeds],
).unwrap();
