आविष्कारक प्लेटफॉर्म आधिकारिक तौर पर वेब 3 चेन पर कॉन्ट्रैक्ट इंटरैक्टिव कॉलिंग का उपयोग करता है, यह टेम्पलेट एक ट्रेडिंग क्लास लाइब्रेरी है, जिसे यूनिसैप v3 के रूप में उदाहरण दिया गया है, जो अन्य डेफी एक्सचेंजों तक आसानी से पहुंच सकता है।
फ़ंक्शन कॉल का सारांश नीचे दिया गया है, और विस्तृत दस्तावेज़ीकरण के बाद इसे प्लेटफ़ॉर्म एपीआई दस्तावेज़ में शामिल किया जाएगा।
कॉलिंग कॉन्ट्रैक्ट यदि मानक ERC20 विधि को पंजीकरण की आवश्यकता नहीं है, तो सीधे कॉल करें, तीसरा पैरामीटर मजबूत संगतता के साथ विधि नाम लिख सकता है, methodId उदाहरण के लिए "0x571ac8b0", या पूर्ण मानक विधि नाम लिख सकते हैं। निरंतर गुणों के साथ विधि सीधे फ़ंक्शन परिणाम लौटाती है, गैर-निरंतर विधि जैसे कि approve सीधे प्रसारण के बाद txid लौटाती है
exchange.IO("api", tokenAddress, "decimals")
exchange.IO("api", tokenAddress, "approve", 0x......., "0xfffffffffffff")
exchange.IO("api", tokenAddress, "approve(address,uint256)", 0x......., "0xfffffffffffff")
मानक अनुबंध के अलावा अन्य तरीकों को कॉल करने के लिए एबीआई सामग्री को पंजीकृत करना आवश्यक है, अधिक जानकारी के लिए इस टेम्पलेट कोड उदाहरण को देखें, पंजीकरण के बाद अनुबंध के अन्य तरीकों को कॉल किया जा सकता है
exchange.IO("abi", tokenAddress, abiContent)
अनुबंध प्राप्त करने के लिए एबीआई सामग्री को निम्न URL पर प्राप्त किया जा सकता है, केवल परिणाम फ़ील्ड लें
https://api.etherscan.io/api?module=contract&action=getabi&address=0x68b3465833fb72A70ecDF485E0e4C7bD8665Fc45
यदि कॉल विधि payable है, तो विधि के नाम के बाद एक स्थानांतरण ETH का मान ((चौथा मान) जोड़ना आवश्यक है, जैसे कि निम्नलिखित फ़ंक्शन में पैरामीटर का मान 123 है, निश्चित रूप से स्ट्रिंग के नंबर भी पारित किए जा सकते हैं।
exchange.IO("api", ContractV3SwapRouterV2, "multicall(uint256,bytes[])", 123, (new Date().getTime() / 1000) + 3600, "")
आप अतिरिक्त पैरामीटर भी भेज सकते हैं gasLimit/gasPrice/nonce निर्दिष्ट करें
exchange.IO("api", ContractV3SwapRouterV2, "multicall(uint256,bytes[])", ..., {gasPrice: 123456, gasLimit: 21000})
अगर IO का दूसरा पैरामीटर हैeth
और फिर आप सीधे नोड सर्वर पर सभी उपलब्ध आरपीसी विधियों को कॉल करते हैं, जैसे कि
exchange.IO("api", "eth", "eth_getBalance", self.walletAddress, "latest")
ईटीएच भेजने के लिए अतिरिक्त send फ़ंक्शन को जोड़कर ट्रांसफर को आसान बनाया गया
exchange.IO("api", "eth", "send", toAddress, toAmount)
encode/encodePacked के साथ decode विधि प्रदान की जाती है, जो फ़ंक्शन कॉल कोड को हेक्स स्ट्रिंग प्रारूप में वापस कर सकती है, और इस टेम्पलेट कोड में uniswap v3 के लिए मल्टीकल कॉल पढ़ सकती है
// can encode with tuple
let types = "tuple(a uint256,b uint8,c address),bytes"
let ret = exchange.IO("encode", types, {
a: 30,
b: 20,
c: "0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2"
}, "0011")
Log("encode: ", ret)
// decode tuple
Log("decode:", exchange.IO("decode", types, ret))
// join packed types
let path = exchange.IO("encodePacked", "address,uint24,address", tokenAddressMap['1INCH'], 3000, tokenAddressMap['USDT'])
// pack method call
let rawData = exchange.IO("encode", ContractV3SwapRouterV2, "checkOracleSlippage(bytes,uint24,uint32)", path, 10000, 600)
// parse abi raw data
Log("method hash:", rawData.slice(0, 8))
निजी कुंजी को किसी भी समय स्विच किया जा सकता है और कई पते संचालित किए जा सकते हैं, जैसेः
exchange.IO("key", "219103fb1e058720b8431580cdc61ed77a270bac1f87503145b9e9b5cd8a92ce")
एबीआई आंतरिक चर रूपांतरण नियम
address: 0x से शुरू होने वाला स्ट्रिंग
बाइट्सः एक सोलह अंकों का कोडित स्ट्रिंग, जैसे कि 008395"
uint256: स्ट्रिंग या संख्या हो सकती है
uniswap टेम्पलेट कॉल का उदाहरण नीचे दिया गया है, एक्सचेंज वेब 3 जोड़ें, नोड पते को निजी कुंजी के साथ भरें, निजी कुंजी स्थानीय रूप से सहेजी जा सकती है ((निजी कुंजी को फ़ाइल पथ के रूप में लिखा जाता है), एपीआई दस्तावेज देखें
नोड एड्रेस को अपने स्वयं के कुंजी के रूप में कॉन्फ़िगर करने के लिए infura के मुफ्त नोड आवेदन के बाद बदला जा सकता हैhttps://mainnet.infura.io/v3/{apikey}
