ভূমিকা
ব্লকচেইন লেনদেনের ক্ষেত্রে, বিকেন্দ্রীভূত এক্সচেঞ্জ (DEX) সম্পদ বিনিময়ের একটি বিশ্বাসহীন উপায় প্রদান করে এবং ট্রন ইকোসিস্টেমে DEX-এর প্রতিনিধি হিসেবে SunSwap, Web3-এর উপর ভিত্তি করে স্মার্ট চুক্তি মিথস্ক্রিয়া সমর্থন করে। FMZ প্ল্যাটফর্ম (FMZ কোয়ান্টিটেটিভ) একটি শক্তিশালী পরিমাণগত ট্রেডিং কাঠামো প্রদান করে যা ডেভেলপারদের একাধিক ট্রেডিং কৌশল একীভূত করতে সক্ষম করে।
FMZ প্ল্যাটফর্মটি ইতিমধ্যেই Web3 Ethereum (ETH) এক্সচেঞ্জ অবজেক্টের এনক্যাপসুলেশন সমর্থন করে এবং সম্প্রতি Web3 TRON-এর জন্য সমর্থন যোগ করেছে, যা TRON চেইনের এক্সচেঞ্জ অবজেক্টগুলিকে এনক্যাপসুলেট করে। UniSwap DEX অ্যাক্সেস করার মতো, SunSwap DEX অ্যাক্সেসও অর্জন করা যেতে পারে।
এই প্রবন্ধে FMZ পরিমাণগত প্ল্যাটফর্মের উপর ভিত্তি করে Web3 ইন্টারফেসকে কীভাবে এনক্যাপসুলেট করা যায় এবং লেনদেনের জন্য SunSwap DEX-এর সাথে কীভাবে সংযোগ স্থাপন করা যায় তা অন্বেষণ করা হবে। আমরা ট্রন নেটওয়ার্কের Web3 ইন্টারঅ্যাকশন পদ্ধতি, সানসোয়াপ স্মার্ট কন্ট্রাক্ট কল, এবং কোড উদাহরণের মাধ্যমে দেখাবো কিভাবে তরলতা অনুসন্ধান করতে হয়, লেনদেন সম্পাদন করতে হয় এবং লেনদেনের ফলাফল পেতে হয়, যাতে একটি দক্ষ পরিমাণগত ট্রেডিং কৌশল তৈরি করা যায়।
বিবৃতি
এই প্রবন্ধে ভাগ করা সমস্ত কোড এবং ডিজাইন পরীক্ষা করা হয়েছে এবং শেখার এবং যোগাযোগের জন্য তৈরি করা হয়েছে। তবে, পরীক্ষার পরেও, প্রকৃত চাহিদার উপর ভিত্তি করে এগুলি সামঞ্জস্য করার প্রয়োজন হতে পারে। যদি আপনার এটি বাস্তব ট্রেডিংয়ে প্রয়োগ করার প্রয়োজন হয়, তাহলে অনুগ্রহ করে নিজেই এটি মূল্যায়ন, অপ্টিমাইজ এবং পরিবর্তন করুন যাতে এটি আপনার নিজস্ব চাহিদা পূরণ করে।

FMZ প্ল্যাটফর্মের Web3 TRON এক্সচেঞ্জ অবজেক্ট কনফিগার করুন
আগের প্রবন্ধে「FMZ কোয়ান্টিটেটিভ ওয়েব3 সম্প্রসারণ: ট্রন সাপোর্ট যোগ করুন এবং অন-চেইন লেনদেনের ক্ষমতা প্রসারিত করুন」এই প্রবন্ধে আমরা পরিচয় করিয়ে দিয়েছিTron gRPC আমরা নোড সেট আপ করার সাধারণ পদ্ধতি এবং FMZ-এ Web3 TRON এক্সচেঞ্জ অবজেক্ট কীভাবে কনফিগার করতে হয় তা শিখেছি। এই প্রবন্ধে এই বিষয়বস্তুর পুনরাবৃত্তি হবে না। নোড ঠিকানার ক্ষেত্রে, আমরা সরাসরি TRON দ্বারা প্রদত্ত নোডটি আনুষ্ঠানিকভাবে ব্যবহার করব।

হোস্ট স্থাপন করুন
CEX এক্সচেঞ্জের বিপরীতে, চিন্তা করার মতো কোনও দেয়াল নেই। আপনি স্থানীয়ভাবে একটি হোস্ট স্থাপন করে অফিসিয়াল নোড অ্যাক্সেস করতে পারেন।

SunSwap DEX
ব্রাউজারে SunSwap-এর ফ্রন্ট-এন্ড পেজটি খুলুন, আপনি ওয়ালেটের সাথে সংযোগ করতে পারবেন এবং সুবিধাজনকভাবে ডেটা পর্যবেক্ষণ করতে পারবেন।

base58
TRON-এর ঠিকানাগুলি base58 এনকোডেড, যা Ethereum থেকে আলাদা। কখনও কখনও ডেটা দেখতে এবং তুলনা করার জন্য কিছু রূপান্তরের প্রয়োজন হয়। FMZ-এ, আপনি সরাসরি base58-এনকোডেড ঠিকানা ব্যবহার করতে পারেন। কিছু স্মার্ট চুক্তি HEX এনকোডিংয়ে ডেটা ফেরত দেয়, যার জন্য কিছু রূপান্তর প্রয়োজন। ঠিকানা বিন্যাস রূপান্তর করার জন্য বেশ কয়েকটি ফাংশন সহজভাবে প্রয়োগ করা হয়:
নিম্নলিখিত প্রধান রূপান্তর ফাংশনগুলি রয়েছে। সীমিত স্থানের কারণে, আমি সব কোড পোস্ট করব না। সম্পূর্ণ কোডটি "Tron SunSwap V3 Trading Library" টেমপ্লেট লাইব্রেরিতে রয়েছে যা নিবন্ধের শেষে প্রকাশিত হয়েছে।
javascriptfunction ethAddressToTron(ethAddress) { if (!/^0x[0-9a-fA-F]{40}$/.test(ethAddress)) { throw "Invalid Ethereum address" } const ethAddressBytes = new Uint8Array(20) for (let i = 0; i < 20; i++) { ethAddressBytes[i] = parseInt(ethAddress.substr(2 + i * 2, 2), 16) } const tronAddressBytes = new Uint8Array(21) tronAddressBytes[0] = 0x41 tronAddressBytes.set(ethAddressBytes, 1) const hash1 = Encode("sha256", "hex", "hex", uint8ArrayToHex(tronAddressBytes)) const hash2 = Encode("sha256", "hex", "hex", hash1) const checksum = hash2.slice(0, 8) const fullAddress = new Uint8Array(25) fullAddress.set(tronAddressBytes, 0) fullAddress.set(hexToUint8Array(checksum), 21) return base58Encode(fullAddress) } -
প্যাকেজ কল
যেহেতু কখনও কখনও আপনাকে একসাথে একাধিক পদ্ধতি থেকে ডেটা পড়তে হয়, তাই একে একে কল করা সময়সাপেক্ষ এবং শ্রমসাধ্য। সুতরাং একটি প্যাকেজড কলিং ফাংশন এনক্যাপসুলেটেড:
javascriptfunction multicall(e, multicallContractAddress, data, outTypes) { let ret = e.IO("api", multicallContractAddress, "aggregate", data) if (!ret || !ret["returnData"] || !Array.isArray(ret["returnData"])) { Log("invalid ret:", ret) return null } let arrRet = ret["returnData"] if (outTypes.length != arrRet.length) { Log("Arrays have unequal lengths:", arrRet, outTypes) return null } let outData = [] for (let i in arrRet) { outData.push(e.IO("decode", outTypes[i], arrRet[i])) } return outData }
ট্রন সানসোয়াপ ভি৩ ট্রেডিং লাইব্রেরি
SunSwap V3 ট্রেডিং লাইব্রেরির নকশা FMZ প্ল্যাটফর্মের UniSwap ট্রেডিং লাইব্রেরি টেমপ্লেটের অনুকরণে তৈরি। যেহেতু সানসোয়াপ টেমপ্লেট কোডটি তুলনামূলকভাবে দীর্ঘ, আমি এখানে এটি পোস্ট করব না, তবে মূলত বাস্তবায়িত ফাংশনগুলি ব্যাখ্যা করব।
সানসোয়াপ লেনদেনের বস্তু তৈরি করুন
javascript
let e = $.CreateSunSwapEx() // 默认使用exchange即exchanges[0]初始化SunSwap交易对象。
// let e = $.CreateSunSwapEx(exchanges[1]) // 使用次交易所对象初始化SunSwap交易对象。
এই টেমপ্লেটটিতে শুধুমাত্র একটি ইন্টারফেস ফাংশন রয়েছে, যথা:$.CreateSunSwapEx()সানসোয়াপ লেনদেনের বস্তু তৈরি করতে ব্যবহৃত হয়। অবজেক্ট তৈরি হওয়ার পর, আপনি কিছু কার্যকরী কল করার জন্য এই অবজেক্টের পদ্ধতিতে কল করতে পারেন, যেমন: রিডেম্পশন লেনদেন, পুলের দাম জিজ্ঞাসা করা, সমস্ত V3 পুলের তথ্য প্রাপ্ত করা, অঙ্গীকার, ডিকম্প্রেশন ইত্যাদি।

"Tron SunSwap V3 Trading Library" এর পরীক্ষা কোডটি টেমপ্লেটে রয়েছে।main()ফাংশনটি রেকর্ড করা হয়েছে এবং এখানে পুনরাবৃত্তি করা হবে না।
javascript
let markets = e.GetMarkets()
let idx = 0
let tbl = {"type": "table", "title": "test GetMarkets", "cols": ["Index", "PoolAddress", "Symbol", "BaseAsset", "QuoteAsset", "BaseName", "QuoteName", "BaseDecimals", "QuoteDecimals", "BaseAddress", "QuoteAddress"], "rows": []}
for (let currency in markets) {
let arrMarket = markets[currency]
for (let market of arrMarket) {
tbl["rows"].push([idx, market["PoolAddress"], market["Symbol"], market["BaseAsset"], market["QuoteAsset"], market["BaseName"], market["QuoteName"], market["BaseDecimals"], market["QuoteDecimals"], market["BaseAddress"], market["QuoteAddress"]])

ফাংশনGetMarkets()SunSwap V3 পুলের সমস্ত এক্সচেঞ্জ পুলের প্রাসঙ্গিক তথ্য সংগ্রহ করতে ব্যবহৃত হয়, যা SunSwap লেনদেন বস্তুর ভেরিয়েবলে ক্যাশে করা হয় এবং অন্যান্য ক্রিয়াকলাপের সময় নির্ভুলতা, ঠিকানা এবং অন্যান্য তথ্য অনুসন্ধান করতে ব্যবহৃত হয়।
এই পরীক্ষার কোডটি চালানোর পরে সমস্ত V3 পুল সম্পর্কে তথ্য প্রদর্শন করবে:
"ফিশিং চুক্তি" এবং "অবৈধ চুক্তি" এর মতো কিছু চুক্তির ঠিকানা যা এখন পর্যন্ত দেখা গেছে, কোড থেকে সরিয়ে ফেলা হয়েছে।
GetTicker
javascript
let ticker1 = e.GetTicker("WTRX_USDT")
Log("symbol:", "WTRX_USDT", ", ticker:", ticker1)
let ticker2 = e.GetTicker("iCMX_USDT", "TLVDozYEBgeaJXH7oKBsougzEJKNrogFun") // iCMX_USDT
Log("symbol:", "iCMX_USDT", ", ticker:", ticker2)
ব্যবহার করা যাবেGetTicker()ফাংশনটি একটি নির্দিষ্ট এক্সচেঞ্জ পুলের দাম জিজ্ঞাসা করে এবং একটি নির্দিষ্ট পুলের ঠিকানা নির্দিষ্ট করতে পারে। মনে রাখবেন যে কিছু পুলের তরলতা খুবই কম এবং দামগুলি শুধুমাত্র রেফারেন্সের জন্য।
multicall
javascript
let data = []
let walletAddress = exchange.IO("address")
data.push(["TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t", "0x" + exchange.IO("encode", "TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t", "balanceOf", walletAddress)])
data.push(["TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t", "0x" + exchange.IO("encode", "TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t", "balanceOf", walletAddress)])
Log(data)
let ret = multicall(exchange, "TGXuuKAb4bnrn137u39EKbYzKNXvdCes98", data, ["uint256", "uint256"])
Log(ret, toAmount(ret[0], 6))
এই ফাংশনটি পরবর্তী ফাংশন এনক্যাপসুলেশনের জন্য ব্যবহার করা যেতে পারে। উদাহরণস্বরূপ, উদাহরণে, আপনি রাখতে পারেনbalanceOfমেথড কলটি এনকোড করা আছে এবং ডেটা একবার অনুরোধ করা হয়েছে।
GetSwapOutAmount
javascript
let retBuy = e.GetSwapOutAmount("WTRX_USDT", 1, "buy") // 1 quote -> base
Log("WTRX_USDT", "buy outAmount:", retBuy["outAmount"], ", ask:", (1 / retBuy["outAmount"]))
let retSell = e.GetSwapOutAmount("WTRX_USDT", 1, "sell") // 1 base -> quote
Log("WTRX_USDT", "sell outAmount:", retSell["outAmount"], ", bid:", (retSell["outAmount"] / 1))
এটি একটি অপেক্ষাকৃত গুরুত্বপূর্ণ ফাংশন, যা সানসোয়াপের বুদ্ধিমান রাউটিং পরিষেবাকে অন্তর্ভুক্ত করে। tokenInSymbol এবং tokenOutSymbol দেওয়া হলে, এটি সম্ভাব্য বিনিময় পথ, আউটপুট টোকেনের সংখ্যা এবং অন্যান্য তথ্য ফেরত দিতে পারে।
GetAssets
javascript
let assets = e.GetAssets()
let tbl = {"type": "table", "title": "test GetAssets", "cols": ["Name", "Address", "Decimals", "Balance"], "rows": []}
for (let asset of assets) {
tbl["rows"].push([asset.Currency, asset.Address, asset.Decimals, asset.Amount])
}
LogStatus("`" + JSON.stringify(tbl) + "`")
যেহেতু TRC20 টোকেনগুলি অতিক্রম করার জন্য কোনও ভাল ব্যবস্থা নেই, তাই ট্রনস্ক্যানের ট্র্যাভার্সালের সাহায্যে, এই তৃতীয়-পক্ষের ইন্টারফেসটি অ্যাকাউন্ট সম্পদের তথ্য অনুসন্ধানের জন্য ব্যবহার করা হয়।
Swap
javascript
// 6 USDT -> ? WTRX
let ret = e.Swap("WTRX_USDT", 6, "buy")
Log(ret)
// 10 TRX -> ? WTRX
// let ret = e.Swap("TRX_WTRX", 10, "sell")
// Log(ret)
সবচেয়ে গুরুত্বপূর্ণ কাজ হল এই বিনিময়। এক্সচেঞ্জ কার্যকর করার সময়, ইন্টেলিজেন্ট রাউটিং অনুসারে এক্সচেঞ্জ পাথ তৈরি করা হবে, এবং তারপর টোকেন বিনিময়ের জন্য এক্সচেঞ্জ পদ্ধতিটি ডাকা হবে।
অনুগ্রহ করে মনে রাখবেন যে যদি এটি TRX প্যাকেজিং/আনপ্যাকিং এক্সচেঞ্জ হয়, তবে এটি শুধুমাত্র WTRX চুক্তি পদ্ধতি ব্যবহার করে কার্যকর করা হয়।

এই প্রবন্ধের মাধ্যমে, আমরা FMZ পরিমাণগত প্ল্যাটফর্মের উপর ভিত্তি করে Web3 Tron এনক্যাপসুলেশন উপলব্ধি করেছি এবং সফলভাবে SunSwap DEX-এর সাথে সংযুক্ত হয়েছি, ট্রেডিং পুল অনুসন্ধান থেকে শুরু করে এক্সচেঞ্জ কার্যকর করা এবং লেনদেনের ফলাফল বিশ্লেষণ করা পর্যন্ত সম্পূর্ণ প্রক্রিয়া সম্পন্ন করেছি। এটি কেবল ট্রন ইকোসিস্টেমে DEX লেনদেনের জন্য একটি দক্ষ অটোমেশন সমাধান প্রদান করে না, বরং FMZ পরিমাণগত প্ল্যাটফর্মের শক্তিশালী স্কেলেবিলিটিও প্রদর্শন করে।
আমি আশা করি এই প্রবন্ধের ব্যবহারিক অভিজ্ঞতা আপনার পরিমাণগত ট্রেডিং সিস্টেমের জন্য মূল্যবান রেফারেন্স প্রদান করতে পারবে। এরপর, আমি SOL-তে DEX অধ্যয়ন করব।
পড়ার জন্য ধন্যবাদ~
