def getBalance(publicKey:str):
    solana_client = Client(rpc_url)
    #公钥转换
    pubkey=Pubkey.from_string(publicKey)
    tokenPublicKey=Pubkey.from_string(BOGGY_TOKEN_MINT)
    #获取SOL余额
    sol_balance = solana_client.get_balance(pubkey)
    #获取SPL代币余额
    token_account=solana_client.get_token_accounts_by_owner_json_parsed(pubkey,TokenAccountOpts(mint=tokenPublicKey))
    if noTokenAccount(token_account):
        #不存在代币账户时,则余额为0
        token_balance=0.0
    else:
        token_account_json=token_account.value[0].account.to_json()
        token_balance=json.loads(token_account_json)['data']['parsed']['info']['tokenAmount']['uiAmount']
    sol_balance=(sol_balance.value/10**9)
    return sol_balance,token_balance

同时为方便用户使用,这边会将用户公钥通过qrcode库转换为二维码供用户扫码,主要代码为:


import qrcode
from io import BytesIO
from PIL import Image
import qrcode.main
 
def generate_qr(data):
    # 生成普通二维码
    qr = qrcode.main.QRCode(
        version=1,
        box_size=10,
        border=4,
    )
    qr.add_data(data)
    qr.make(fit=True)
    qr_img = qr.make_image(fill_color="black", back_color="white")
 
    
 
    # 将二维码图片保存到 BytesIO 对象中
    img_io = BytesIO()
    qr_img.save(img_io, format='PNG')
    img_io.seek(0)
    
    return img_io

实现效果:

3.2 游戏功能

游戏功能的设计思路是当用户在群组内输入/game时,根据(群组id+用户id+消息id)生成唯一的游戏id并通过json文件存储创建者生成的随机值信息.存储信息如下:


{
	"create_user_id": 5385955983,
	"create_username": "GameOfBoggy",
	"create_select": 0,
	"pk_user_id": 2038830708,
	"pk_username": "USERT1223",
	"pk_select": 1,
	"pk_select_hex": "4b32e3c83744655cd4ab5cc991a342c99f52c73fa83f2393a995d53baf7aeb42",
	"amount": 20,
	"winner": "USERT1223",
	"create_select_hex": "bd55d5aa6e461c63c811ff78bb00753c517eba47f086e563783a5e023ff342af",
	"timestamp": 1721092512.869742,
	"create_drand_hex": "e3b4d8b6af061ddc40449d87c57c06d93de8fa73dff0055a07cc8dadb047dd1e",
	"pk_drand_hex": "808391bb3761db7f5be8ba296e143154f043ecced8e7a693698c8490300fe34f"
}

这里的是使用本地secrets库和调用远程的drand随机数链生成两个hash值(create_drand_hex和create_select_hex为创建者游戏结果计算hash,pk_select_hex和pk_drand_hex为pk者游戏结果计算hash,这些结果面会保存到链上以保证游戏结果公平性和随机性.),这两个hash值转换为整数相加并对3取余获得随机结果,以保证游戏的随机性和不可预测性:

调用远程drand API:


def get_drand_randomness():
    # Drand API endpoint
    url = "https://api.drand.sh/52db9ba70e0cc0f6eaf7803dd07447a1f5477735fd3f661792ba94600c84e971/public/latest"
    # Send request to Drand
    response = requests.get(url)
    if response.status_code == 200:
        # Parse the JSON response
        data = response.json()
        randomness = data['randomness']
        return randomness
    else:
        return secrets.token_hex()

计算游戏随机结果:


def get_random_hex_int():
    select_hex=secrets.token_hex()
    drand_hex=get_drand_randomness()
    hex_int = int(select_hex, 16)
    drand_int = int(drand_hex,16)
    select=(drand_int+hex_int)%3
    return select,select_hex,drand_hex

为保证游戏的美观性,这边使用图片+文字方式让机器人回复用户随机结果:


def random_game(bot,message,type,create_username):
    select,select_hex,drand_hex = get_random_hex_int()
    imgPath="./img/{}.png".format(img[select])
    msgText="<b>[{}] You random [{}]! @{}</b>".format(type,img[select],create_username)
    send_message=bot.send_photo(message.chat.id, open(imgPath, 'rb'), caption=msgText,parse_mode='HTML')
    return select,send_message,select_hex,drand_hex

游戏奖励发放给获胜者为代币转移操作,实现代码如下(这里的draw_data即为计算出结果的hash值,将其备注添加链上):


#向绑定账户发送代币
def drawTokenAccount(sender_public_key:str,privateKey:str,draw_public_key:str,tokenAmount,draw_data):
    solana_client = Client(rpc_url)
    #发送者
    sender_pubkey = Pubkey.from_string(sender_public_key)
    #接收者
    draw_pubkey = Pubkey.from_string(draw_public_key)
    #Token代币地址
    token_mint_address = Pubkey.from_string(BOGGY_TOKEN_MINT)
    #发送者keypair
    sender_keypair=Keypair.from_base58_string(privateKey)
    
    try:
        #spl_client客户端
        source_token_account=get_associated_token_address(sender_pubkey,token_mint_address)
        dest_token_account=get_associated_token_address(draw_pubkey,token_mint_address)
        #交易
        transfer_instruction = transfer_checked(
            TransferCheckedParams(
                program_id=TOKEN_PROGRAM_ID,
                source=source_token_account,
                mint=token_mint_address,
                dest=dest_token_account,
                owner=sender_pubkey,
                amount=int(float(tokenAmount) * 1000000000),
                decimals=9,
            )
        )
        memo_instruction=create_memo(MemoParams(
            program_id=MEMO_PROGRAM_ID,
            signer=sender_pubkey,
            message=draw_data.encode('utf-8')
        ))
        # #获取最新的区块hash
        recent_blockhash_resp = solana_client.get_latest_blockhash()
        recent_blockhash=recent_blockhash_resp.value.blockhash
        # # 创建交易并添加转账指令
        transaction = Transaction()
        transaction.add(set_compute_unit_limit(200000))
        transaction.add(set_compute_unit_price(7500))
        transaction.add(transfer_instruction)
        transaction.add(memo_instruction)
        #设置最新区块hash
        transaction.recent_blockhash=recent_blockhash
        #设置手续费支付地址为发送者
        transaction.fee_payer=sender_pubkey
        #签名
        transaction.sign(sender_keypair)
        #发送交易
        response = solana_client.send_raw_transaction(transaction.serialize())
        #打印交易
        return response.value
    except Exception as e:
        print(f"Exception occurred: {str(e)}")
        return "error"

实现效果:

/game 20 即创建了一个奖励为20代币的游戏,这里随机的是[剪刀]

/pk pk者出了[布],所以创建者获得了奖励.

我们可以点击按钮在链上查看奖励内容.

可以看到这里包含了一个转移代币操作,是从pk者转移到创建者中的,同时包含了生成随机结果的hash值以保证游戏的公开和公平性。

3.3 提出功能

用户输入/bind 绑定自己的链上地址后,提出功能即为代币转移操作,主要实现代码如下,这边直接根据用户的ID查到用户的创建的游戏wallet公钥私钥并进行转移:


def drawTokenFromUserId(send_user_id,draw_user_id,gameId,draw_data):
    publicKey,privateKey=get_account(send_user_id)
    drawPublicKey=getPublicKey(draw_user_id)
    amount=get_game_amount(gameId)
    tx=drawTokenAccount(publicKey,privateKey,drawPublicKey,amount,draw_data)
    return amount,tx

3.4 辅助功能

辅助功能即为telebot消息的回复,实现代码如下:

/rules:


from telebot import types
def handle_rules(bot, message):
    # 处理 /start 命令
    markup = types.InlineKeyboardMarkup()
    item1 = types.InlineKeyboardButton("BOGGY GROUP",url="https://t.me/BoggyCoin")
    markup.add(item1)
    welcome_message=(
        "<b>"
        "1.Before starting the game, you need to create(/create) a game wallet and transfer a small amount of sol and BOGGY tokens inward\n\n"
        "2.You can send '/game [amount]' create a game(default amount:500),and the Pker reply /pk with [GAME](need enough sol and BOGGY)\n\n"
        "3.Waiting for the results, the winner will receive the bonus set by the game creator\n\n"
        "4.The [Scissors] will win [Paper],[Parer] will win [Rock],[Rock] will win [Scissors]\n\n"
        "5.You Can at /wallet,draw you all token in you bind wallet,you can send '/bind [address]' bind you wallet\n\n"
        "[Create With #BOGGY]"
        "</b>"
    )
    bot.send_photo(message.chat.id,open("./img/rules.jpeg","rb"),welcome_message,parse_mode='HTML',reply_markup=markup)
def register_handlers(bot):
    bot.message_handler(commands=['rules'])(lambda message: handle_rules(bot, message))

/help:


from telebot import types
def handle_help(bot, message):
    markup = types.InlineKeyboardMarkup()
    item1 = types.InlineKeyboardButton("BOGGY GROUP",url="https://t.me/BoggyCoin")
    markup.add(item1)
    help_text = (
        "<b>Welcome!</b>\n" 
        "<b>Here are the available commands:</b>\n"
        "<b>[/create]         Create you game wallet [DM*]</b>\n"
        "<b>[/bind]           Bind you draw wallet [DM*]</b> \n"
        "<b>[/wallet]         Show you wallet Info and Draw [DM*]</b>\n\n"
        "<b>[/game]           Create Game with amount</b>\n"
        "<b>[/pk]             Reply the Game Message and Pk it</b>\n"
        "<b>[/rules]          View more detailed game rules</b>\n\n"
        "<b>The [DM*] need DM Bot</b>"
    )
    
    bot.send_photo(message.chat.id,open("./img/help.jpeg","rb"),help_text, parse_mode='HTML',reply_markup=markup)
 
def register_handlers(bot):
    bot.message_handler(commands=['help'])(lambda message: handle_help(bot, message))
