Solana/在主网发行您的代币/实现空投程序

我们要实现的空投程序包含两个功能.

1. 任意调用该空投程序的用户, 程序会自动为其创建一个关联代币账户.
2. 转账 5 pxs 给他.

合约程序实现如下.

solana_program::entrypoint!(process_instruction);

pub fn process_instruction(
    _: &solana_program::pubkey::Pubkey,
    accounts: &[solana_program::account_info::AccountInfo],
    _: &[u8],
) -> solana_program::entrypoint::ProgramResult {
    let accounts_iter = &mut accounts.iter();
    let account_user = solana_program::account_info::next_account_info(accounts_iter)?;
    let account_user_spla = solana_program::account_info::next_account_info(accounts_iter)?;
    let account_mana = solana_program::account_info::next_account_info(accounts_iter)?;
    let account_mana_auth = solana_program::account_info::next_account_info(accounts_iter)?;
    let account_mana_spla = solana_program::account_info::next_account_info(accounts_iter)?;
    let account_mint = solana_program::account_info::next_account_info(accounts_iter)?;
    let _ = solana_program::account_info::next_account_info(accounts_iter)?;
    let account_spl = solana_program::account_info::next_account_info(accounts_iter)?;
    let _ = solana_program::account_info::next_account_info(accounts_iter)?;

    solana_program::program::invoke(
        &spl_associated_token_account::instruction::create_associated_token_account_idempotent(
            &account_user.key,
            &account_user.key,
            &account_mint.key,
            &account_spl.key,
        ),
        accounts,
    )?;
    let account_seed = &[];
    let account_bump = solana_program::pubkey::Pubkey::find_program_address(&[account_seed], account_mana.key).1;
    solana_program::program::invoke_signed(
        &spl_token_2022::instruction::transfer_checked(
            &account_spl.key,
            &account_mana_spla.key,
            &account_mint.key,
            &account_user_spla.key,
            &account_mana_auth.key,
            &[],
            5000000000,
            9,
        )?,
        accounts,
        &[&[account_seed, &[account_bump]]],
    )?;

    Ok(())
}

编译该程序后, 使用下面的代码将其部署在主网.

import pxsol
pxsol.config.current = pxsol.config.mainnet

user = pxsol.wallet.Wallet(pxsol.core.PriKey.base58_decode('Put your private key here'))
with open('target/deploy/pxsol_spl.so', 'rb') as f:
    data = bytearray(f.read())
mana = user.program_deploy(data)
print(mana)

Pxs 代币的空投合约在主网上的部署地址为 HgatfFyGw2bLJeTy9HkVd4ESD6FkKu4TqMYgALsWZnE6.

简要分析下该空投程序的涉及账户:

账户	权限	说明
用户账户	3	必须拥有足够的 sol 余额来支付创建新账户所需的费用
用户关联代币账户	1	/
程序账户	0	主网地址 HgatfFyGw2bLJeTy9HkVd4ESD6FkKu4TqMYgALsWZnE6
程序 pda 账户	0	主网地址 5yAqR4gSYfs7CqpR4mgN5DNT4xczwiATuybaAa33xGip
程序 pda 关联代币账户	1	主网地址 G7C9Px4x1G5YE2NmUHG6BeuqavoDsQQsHGpfs7nvMcq9

原生程序: 关联代币程序	0	主网地址 ATokenGPvbdGVxr1b2hvZbsiqW5xWH25efTNsLJA8knL

最后, 不要忘记, 您需要将一些代币转账到程序 pda 账户. 注意: 转账目标不是程序账户而是程序 pda 账户! 代码如下:

import pxsol
pxsol.config.current = pxsol.config.mainnet

user = pxsol.wallet.Wallet(pxsol.core.PriKey.base58_decode('Put your private key here'))
pubkey_mint = pxsol.core.PubKey.base58_decode('6B1ztFd9wSm3J5zD5vmMNEKg2r85M41wZMUW7wXwvEPH')
pubkey_mana = pxsol.core.PubKey.base58_decode('HgatfFyGw2bLJeTy9HkVd4ESD6FkKu4TqMYgALsWZnE6')
pubkey_mana_seed = bytearray([])
pubkey_mana_auth = pubkey_mana.derive_pda(pubkey_mana_seed)
user.spl_transfer(pubkey_mint, pubkey_mana_auth, 100000000 * 10**9)
