Mukadimah
Dalam bidang urus niaga blockchain, pertukaran terdesentralisasi (DEX) menyediakan cara tanpa amanah untuk menukar aset, dan SunSwap, sebagai wakil DEX dalam ekosistem Tron, menyokong interaksi kontrak pintar berdasarkan Web3. Platform FMZ (Kuantiti FMZ) menyediakan rangka kerja dagangan kuantitatif yang berkuasa yang membolehkan pembangun menyepadukan berbilang strategi dagangan.
Platform FMZ sudah pun menyokong pengkapsulan objek pertukaran Web3 Ethereum (ETH), dan baru-baru ini menambah sokongan untuk Web3 TRON, merangkum objek pertukaran rantaian TRON. Sama seperti mengakses UniSwap DEX, akses kepada SunSwap DEX juga boleh dicapai.
Artikel ini akan meneroka cara merangkum antara muka Web3 berdasarkan platform kuantitatif FMZ dan menyambung ke SunSwap DEX untuk transaksi. Kami akan memperkenalkan kaedah interaksi Web3 rangkaian Tron, panggilan kontrak pintar SunSwap, dan menunjukkan melalui contoh kod cara untuk bertanya kecairan, melaksanakan urus niaga dan mendapatkan hasil transaksi, untuk membina strategi perdagangan kuantitatif yang cekap.
kenyataan
Semua kod dan reka bentuk yang dikongsi dalam artikel ini telah diuji dan bertujuan untuk pembelajaran dan komunikasi. Walau bagaimanapun, walaupun selepas ujian, ini mungkin masih perlu diselaraskan berdasarkan keperluan sebenar. Jika anda perlu menerapkannya pada dagangan sebenar, sila pastikan anda menilai, mengoptimumkan dan mengubah suainya sendiri untuk memastikan ia memenuhi keperluan anda sendiri.
Persediaan
- Konfigurasikan objek pertukaran Web3 TRON platform FMZ
Dalam artikel sebelum ini「Peluasan Web3 Kuantitatif FMZ: Tambah sokongan Tron dan kembangkan keupayaan transaksi dalam rantaian」Dalam artikel ini kami telah memperkenalkanTron gRPC Kami telah mempelajari kaedah biasa untuk menyediakan nod dan cara mengkonfigurasi objek pertukaran Web3 TRON pada FMZ. Artikel ini tidak akan mengulangi kandungan ini. Bagi alamat nod, kami akan terus menggunakan nod yang disediakan oleh TRON secara rasmi.
- Sebarkan hos
Tidak seperti pertukaran CEX, tiada tembok yang perlu dibimbangkan. Anda boleh mengakses nod rasmi dengan menggunakan hos secara tempatan.
- SunSwap DEX
Buka halaman hujung hadapan SunSwap dalam penyemak imbas, anda boleh menyambung ke dompet dan memerhati data dengan mudah.
- tronscan
Alat penting untuk melihat dan menganalisis data.
- base58
Alamat di TRON adalah dikodkan base58, yang berbeza daripada Ethereum. Kadangkala beberapa penukaran diperlukan untuk melihat dan membandingkan data. Pada FMZ, anda boleh terus menggunakan alamat berkod base58. Sesetengah kontrak pintar mengembalikan data dalam pengekodan HEX, yang memerlukan beberapa penukaran. Beberapa fungsi hanya dilaksanakan untuk menukar format alamat:
Berikut adalah fungsi penukaran utama. Oleh kerana ruang terhad, saya tidak akan menghantar semua kod. Kod lengkap terdapat dalam perpustakaan templat “Tron SunSwap V3 Trading Library” yang didedahkan pada penghujung artikel.
function 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)
}
- Panggilan pakej
Memandangkan kadangkala anda perlu membaca data daripada pelbagai kaedah sekaligus, memanggilnya satu demi satu memakan masa dan susah payah. Jadi fungsi panggilan berpakej dirangkumkan:
function 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
}
Perpustakaan Perdagangan Tron SunSwap V3
Reka bentuk perpustakaan dagangan SunSwap V3 dimodelkan selepas templat perpustakaan dagangan UniSwap platform FMZ. Memandangkan kod templat SunSwap agak panjang, saya tidak akan menyiarkannya di sini, tetapi terutamanya akan menerangkan fungsi yang dilaksanakan.
Buat objek transaksi SunSwap
let e = $.CreateSunSwapEx() // 默认使用exchange即exchanges[0]初始化SunSwap交易对象。
// let e = $.CreateSunSwapEx(exchanges[1]) // 使用次交易所对象初始化SunSwap交易对象。
Templat ini hanya mempunyai satu fungsi antara muka iaitu:$.CreateSunSwapEx()Digunakan untuk mencipta objek transaksi SunSwap. Selepas objek dibuat, anda boleh memanggil kaedah objek ini untuk membuat beberapa panggilan berfungsi, seperti: transaksi penebusan, harga kumpulan pertanyaan, dapatkan semua maklumat kumpulan V3, ikrar, penyahmampatan, dsb.
GetMarkets
Kod ujian “Tron SunSwap V3 Trading Library” terdapat dalam templatmain()Fungsi tersebut telah direkodkan dan tidak akan diulang di sini.
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"]])
idx++
}
}
LogStatus("`" + JSON.stringify(tbl) + "`")
fungsiGetMarkets()Digunakan untuk mendapatkan maklumat berkaitan semua kumpulan pertukaran kumpulan SunSwap V3, dicache dalam pembolehubah objek transaksi SunSwap, dan digunakan untuk menanyakan ketepatan, alamat dan maklumat lain semasa operasi lain.
Kod ujian ini akan memaparkan maklumat tentang semua kumpulan V3 selepas dijalankan:
Beberapa alamat kontrak seperti “kontrak pancingan data” dan “kontrak tidak sah” yang dilihat setakat ini telah dialih keluar daripada kod tersebut.
GetTicker
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)
Boleh digunakanGetTicker()Fungsi ini menanyakan harga kumpulan pertukaran tertentu dan boleh menentukan alamat kumpulan tertentu. Ambil perhatian bahawa sesetengah kumpulan mempunyai kecairan yang sangat lemah dan harga adalah untuk rujukan sahaja.
multicall
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))
Fungsi ini boleh digunakan untuk enkapsulasi fungsi seterusnya. Sebagai contoh, dalam contoh, anda boleh meletakkanbalanceOfPanggilan kaedah dikodkan dan data diminta sekali.
GetSwapOutAmount
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))
Ini adalah fungsi yang agak penting, yang merangkumi perkhidmatan penghalaan pintar SunSwap. Memandangkan tokenInSymbol dan tokenOutSymbol, ia boleh mengembalikan laluan pertukaran yang mungkin, bilangan token output dan maklumat lain.
GetAssets
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) + "`")
Memandangkan tiada mekanisme yang baik untuk melintasi token TRC20, dengan bantuan traversal tronscan, antara muka pihak ketiga ini digunakan untuk menanyakan maklumat aset akaun.
Swap
// 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)
Fungsi yang paling penting ialah pertukaran ini. Apabila melaksanakan pertukaran, laluan pertukaran akan dirumuskan mengikut penghalaan pintar, dan kemudian kaedah pertukaran akan dipanggil untuk menukar token. Sila ambil perhatian bahawa jika ia adalah pertukaran pembungkusan/membongkar TRX, ia hanya dilaksanakan menggunakan kaedah kontrak WTRX.
Terdapat beberapa fungsi lain yang boleh ditambah pada kod templatmain()Fungsi, saya tidak akan pergi ke butiran.
Kod Templat
Templat ini tidak mempunyai apa-apaReka Bentuk InteraksidanParameter antara muka, ia hanya menyedari fungsi asas untuk mengakses SunSwap DEX, dan lebih banyak fungsi boleh dioptimumkan dan ditambah pada masa hadapan.
