PrintFun is built on the Solana blockchain, leveraging its high performance and low transaction costs to provide an efficient token creation and management platform.

Smart Contract Architecture

Token Contract

• Built on Solana Program Library (SPL)

• Implements SPL Token standard

• Custom extensions for max wallet and tax on-platform

Custom Mechanisms

Max Wallet Implementation

// Pseudo-code representation
pub fn check_max_wallet(
    holder: AccountInfo,
    amount: u64,
    max_limit: u64
) -> ProgramResult {
    let current_balance = holder.balance();
    require!(
        current_balance + amount <= max_limit,
        "Exceeds max wallet limit"
    );
    Ok(())
}

Tax Collection System

// Pseudo-code representation
pub fn process_transaction(
    amount: u64,
    tax_rate: u8,
    distribution: Distribution
) -> ProgramResult {
    let tax_amount = calculate_tax(amount, tax_rate);
    distribute_tax(tax_amount, distribution)?;
    process_main_transfer(amount - tax_amount)
}
