موجد پلیٹ فارم کو ویب 3 چین پر معاہدہ کرنے والے انٹرایکٹو کالوں تک باضابطہ رسائی حاصل ہے۔ یہ ٹیمپلیٹ ایک تجارتی کلاس لائبریری ہے جس میں یونیسواپ وی 3 کی مثال دی گئی ہے ، جو دوسرے ڈی ایف آئی تبادلے تک آسانی سے رسائی حاصل کرنے کے قابل ہے۔
ذیل میں فنکشن کالوں کا خلاصہ ہے۔ تفصیلی دستاویزات مکمل ہونے کے بعد پلیٹ فارم API دستاویزات میں شامل کی جائیں گی۔ یہاں کچھ مثالیں ہیں۔
کال معاہدہ اگر معیاری ERC20 طریقہ ہے تو رجسٹریشن کی ضرورت نہیں ہے ، براہ راست کال کریں ، تیسری پیرامیٹر مضبوط مطابقت رکھتا ہے طریقہ نام لکھ سکتے ہیں ، طریقہ ID مثال کے طور پر "0x571ac8b0" ، یا مکمل معیاری طریقہ نام لکھ سکتے ہیں۔ مستقل خصوصیات کے طریقوں سے براہ راست فنکشن کے نتائج واپس آتے ہیں ، غیر مستقل طریقوں جیسے منظور براہ راست واپس آتے ہیں txid
exchange.IO("api", tokenAddress, "decimals")
exchange.IO("api", tokenAddress, "approve", 0x......., "0xfffffffffffff")
exchange.IO("api", tokenAddress, "approve(address,uint256)", 0x......., "0xfffffffffffff")
معیاری معاہدے کے علاوہ دیگر طریقوں کو کال کرنے کے لئے اے بی آئی کے مواد کو رجسٹر کرنا ضروری ہے۔ مزید تفصیلات کے لئے اس ٹیمپلیٹ کا کوڈ مثال دیکھیں۔
exchange.IO("abi", tokenAddress, abiContent)
معاہدہ حاصل کرنے کے لئے اے بی آئی کا مواد درج ذیل یو آر ایل سے حاصل کیا جاسکتا ہے ، صرف نتائج کے فیلڈ کو منتخب کریں
https://api.etherscan.io/api?module=contract&action=getabi&address=0x68b3465833fb72A70ecDF485E0e4C7bD8665Fc45
اگر کال کرنے والا طریقہ payable ہے تو ، طریقہ نام کے بعد منتقلی کے ETH کی قیمت ((چوتھا قدر) شامل کرنے کی ضرورت ہے ، لہذا اگر مندرجہ ذیل فنکشن میں پیرامیٹر کی قیمت 123 ہے تو ، یقینا string اسٹرنگ کی تعداد بھی منتقل کی جاسکتی ہے۔
exchange.IO("api", ContractV3SwapRouterV2, "multicall(uint256,bytes[])", 123, (new Date().getTime() / 1000) + 3600, "")
اضافی پیرامیٹرز بھی منتقل کر سکتے ہیں gasLimit/gasPrice/nonce کی وضاحت کریں
exchange.IO("api", ContractV3SwapRouterV2, "multicall(uint256,bytes[])", ..., {gasPrice: 123456, gasLimit: 21000})
اگر IO کا دوسرا پیرامیٹر ہےeth
اس کے بعد، آپ کو اپنے سرور پر تمام دستیاب آر پی سی کے طریقوں کو براہ راست کال کرنے کی ضرورت ہے.
exchange.IO("api", "eth", "eth_getBalance", self.walletAddress, "latest")
ٹرانسفر کو آسان بنانے کے لیے، اضافی send فنکشن کو ETH بھیجنے کے لیے شامل کیا گیا۔
exchange.IO("api", "eth", "send", toAddress, toAmount)
encode/encodePacked کے ساتھ decode طریقہ فراہم کرتا ہے، جس سے فنکشن کال انکوڈنگ کو ہیکس سٹرنگ فارمیٹ میں واپس کیا جاسکتا ہے، اس ٹیمپلیٹ کوڈ میں uniswap v3 کے لئے ملٹی کال کال پڑھ سکتے ہیں۔

let types = "tuple(a uint256,b uint8,c address),bytes"

Log("encode: ", ret)
// decode tuple

// parse abi raw data
Log("method hash:", rawData.slice(0, 8))
آپ اپنی نجی کلید کو کسی بھی وقت تبدیل کر سکتے ہیں اور متعدد پتے پر کام کرسکتے ہیں ، جیسے:
exchange.IO("key", "219103fb1e058720b8431580cdc61ed77a270bac1f87503145b9e9b5cd8a92ce")
ABI اندرونی متغیر تبادلوں کے قوانین
address: 0x سے شروع ہونے والا سٹرنگ
بائٹس: سولہ ہندسوں کا انکوڈنگ سٹرنگ، جیسے 008395"
uint256: ایک سٹرنگ یا ایک نمبر ہو سکتا ہے
uniswap ٹیمپلیٹ کال کی مثال مندرجہ ذیل ہے، ایکسچینج ویب 3 کو شامل کریں، نوڈ ایڈریس کو نجی کلید کے ساتھ بھریں، نجی کلید مقامی طور پر محفوظ کی جاسکتی ہے (نجی کلید کو فائلوں کے راستے کے طور پر لکھا جاتا ہے) ، مزید تفصیلات کے لئے API دستاویزات دیکھیں
نوڈ ایڈریس کو انفورا کی مفت نوڈ درخواست کے بعد اپنی کلید کے طور پر تبدیل کرنے کے لئے تشکیل دیا جاسکتا ہےhttps://mainnet.infura.io/v3/{پیکیے}
