発明者プラットフォームはweb3チェーンの契約インタラクティブコールへの公式アクセス,このテンプレートは,uniswap v3を例として,他のdefi取引所に簡単にアクセスできる手作業能力を持つ取引クラスデータベースです.
概要の関数呼び出しは以下のとおりです.詳細なドキュメントが書き上げられた後,プラットフォームAPIのドキュメントに統合されます.
契約を呼び出す場合,標準ERC20メソッドは登録を必要とせず,直接呼び出す場合,第3パラメータは高度な互換性があり,メソッド名,methodIdは"0x571ac8b0"などで,完全な標準メソッド名も書くことができます. constant属性を持つ方法が関数の結果を直接返します.非コンスタントの方法が txid を直接返します.
exchange.IO("api", tokenAddress, "decimals")
exchange.IO("api", tokenAddress, "approve", 0x......., "0xfffffffffffff")
exchange.IO("api", tokenAddress, "approve(address,uint256)", 0x......., "0xfffffffffffff")
標準契約以外の方法を呼び出すには,ABI のコンテンツを登録する必要があります.詳細については,このテンプレートのコード例を参照してください.
exchange.IO("abi", tokenAddress, abiContent)
契約取得のABIコンテンツは,以下のURLで取得できます.
https://api.etherscan.io/api?module=contract&action=getabi&address=0x68b3465833fb72A70ecDF485E0e4C7bD8665Fc45
呼び出し方法がpayableである場合,方法名の後ろに転送ETHの値 ((第4値) を追加する必要があります.
exchange.IO("api", ContractV3SwapRouterV2, "multicall(uint256,bytes[])", 123, (new Date().getTime() / 1000) + 3600, "")
また,余分なパラメータを入力することもできます. gasLimit/gasPrice/nonce を指定します.
exchange.IO("api", ContractV3SwapRouterV2, "multicall(uint256,bytes[])", ..., {gasPrice: 123456, gasLimit: 21000})
この2つの項目は,eth
RPCのすべての方法を直接ノードサーバーに呼び出す.
exchange.IO("api", "eth", "eth_getBalance", self.walletAddress, "latest")
送金便宜のために,追加された send 機能で ETH を送信します.
exchange.IO("api", "eth", "send", toAddress, toAmount)
Encode/encodePacked と decode 方法が提供され,関数呼び出しのエンコードをヘックス文字列形式に戻すことができ,このテンプレートコードで uniswap v3 のマルチコール呼び出しを読み取ることができます.
// 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))
プライベートキーをいつでも切り替えて,複数のアドレス操作できます.
exchange.IO("key", "219103fb1e058720b8431580cdc61ed77a270bac1f87503145b9e9b5cd8a92ce")
ABI内部変数変換ルール
アドレス: 0xから始まる文字列
バイト: 16桁の文字列,例えば"008395"
uint256:文字列でも数字でもできます.
uniswap テンプレートの呼び出し例は以下の通り,交換所Web3を追加し,ノードアドレスをプライベートキーで満たし,プライベートキーはローカルに保存できる (私钥はファイルへのパスとして記述される).詳細についてはAPIドキュメントを参照してください.
ノードアドレスは,infuraの無料ノードアプリケーションを使用して,代わりに自分のキーで設定できます.https://mainnet.infura.io/v3/{cH00ffff}私は,あなたが知っている
