FMZ を使って簡単な入門 エーサインベースのweb3開発

s, balanceOf, walletAddress) メールのアドレス Log ((WETH 精度: toAmount,wethBalance,wethDecimals,wethBalance: toAmount)) Log () リンク精度: , linkDecimals, link バランス: , toAmount () リンクバランス, linkDecimals) {cH00ffff}

运行以上代码，可以查询到当前钱包的WETH、LINK代币余额：

> WETH精度： 18 wethBalance: 0
> LINK精度： 18 linkBalance: 51.41374973681053

#### deposit

可以看到这个钱包中WETH代币的余额是0，接下来我们继续和WETH代币的ERC20智能合约交互，这次我们调用Write类型的方法：```deposit```。
```deposit```方法的作用简单来说就是可以把一定量的ETH换为WETH，需要注意```deposit```方法没有参数（可以通过查看ABI观察到），该方法的属性```payable```为```true```，所以调用时需要设置转账ETH（payableAmount）数量，用来指定存入的ETH数量。

> 调用智能合约方法时注意：
> 如果调用的方法具有payable属性，需要在方法名后加一个转账ETH的值(exchange.IO函数的第四个参数)，可以是数值类型，也可以传字符串形式的数值。

```javascript
function toAmount(s, decimals) {
    return Number((BigDecimal(BigInt(s)) / BigDecimal(Math.pow(10, decimals))).toString())
}

function toInnerAmount(s, decimals) {
    return (BigDecimal(s)*BigDecimal(Math.pow(10, decimals))).toFixed(0)
}

    let ethBalance = exchange.IO("api", "eth", "eth_getBalance", walletAddress, "latest")
    Log("ETH精度：", 18, "ethBalance:", toAmount(ethBalance, 18))

    // 调用deposit方法，由于deposit是ERC20标准之外的方法，所以这里要注册这个方法的ABI

    let ret = exchange.IO("api", wethAddress, "deposit", payableAmount)

WETH 精度: 18 ウェス バランス: 0 ETH精度: 18 eth バランス: 0.14333094664072302 トランザクションハッシュ: 0xaf15b0b0e25a81eda583295e82b249e2d02e4eafebecc906470ccc2c89e23563

WETHとETHのバランスを再確認します.

WETH精度: 18weth バランス: 0.01 ETH精度: 18 eth バランス: 0.1333309358060905

呼び出しdepositその前にWETHこれは0です.ETH呼び出し番号は0.14333094664072302ですdepositその後のことWETH半径は0.01です.ETH0.01 を成功裏に実行していることがわかります.ETH引き換えにWETH。

移転

ERC20トークンも送金され,使用できます.transferこのアドレスへの転送方法0x4D75a08E870674E68cAE611f329A27f446A66813ローナンスローナンスローナンスtransfer方法には2つのパラメータがあります.dst送金相手のウォレットアドレスです.wad送金金額は,

function toAmount(s, decimals) {
    return Number((BigDecimal(BigInt(s)) / BigDecimal(Math.pow(10, decimals))).toString())
}

function toInnerAmount(s, decimals) {
    return (BigDecimal(s)*BigDecimal(Math.pow(10, decimals))).toFixed(0)
}

function waitMined (tx) {

        Sleep(5000)
        let info = exchange.IO("api", "eth", "eth_getTransactionReceipt", tx)
        if (info && info.gasUsed) {
            Log(info)
            return true
        }
        Log('Transaction not yet mined', tx)

    // goerli WETH address 
    let wethAddress = "0xB4FBF271143F4FBf7B91A5ded31805e42b2208d6"

この例では,定式関数を使用します.waitMinedこの関数は,この関数の関数で,eth_getTransactionReceipt方法? waitMined のカスタム関数は,入力されたトランザクションハッシュの結果を取得するのを待っている.

    let wad = toInnerAmount(0.01, 18)
    let ret = exchange.IO("api", wethAddress, "withdraw", wad)
    Log("Transaction Hash:", ret)
}

このビデオでは,deposit方法の例は基本的には同じですが,最後のステップで呼び出す方法が入れ替わります.withdraw呼び出す前に:

WETH精度: 18weth バランス: 0.01 ETH精度: 18 eth バランス: 0.11322979983231546

再び検索する:

WETH 精度: 18 ウェス バランス: 0 ETH精度: 18 eth バランス: 0.1231207156449464

再び 0.01 になります.WETH交換しましたETH。

ユニスワップ V3

Uniswap V3仮想通貨の取引と流動性を実現するために,イーサリアム・ブロックチェーン上に構築された分散された取引プロトコルである.これは,コア契約,プール契約,工場契約,ルーティング契約など,一連のスマートコントラクトで構成されている.

使用中Uniswap現在の交換価格を問い合わせ,交換操作を実行する際には,主に以下の契約を使用します.

• Router(ルート契約) これは取引を実行するための契約であり,ユーザが取引経路とパラメータを指定して取引操作を行うことを許可する.
• Pool(池の契約) 池の契約はUniswap特定の資産ペアの流動性を保存し管理する重要な構成要素である. 各資産ペアには,流動性プロバイダが提供する資金,価格範囲,手数料設定などの情報を含む対応するプール契約があります. プール契約は,取引を処理し,資金池の状態を計算し,取引の順調な実行を保証します.
• Factory(工場契約) 工場の契約は,作成と管理のために使用されますUniswap池契約の契約.ユーザが新しいアセットペアを作成したいとき,彼らは工場契約と相互作用することによって新しい池契約を展開する. 工場契約は池契約の作成と初期化を調整し,ユーザが動的に新しい資産ペアを作成することができます.

FMZの量化取引プラットフォームの戦略コードにスマートコントラクトを登録する方法を再検討しましょう.ABI電子商取引のABIを取得する方法については,前回のレッスンで説明しましたが,ここでは説明しません. 3つの登録が必要です.UniswapスマートコントラクトABI電子商取引の例として,

上記のコードは工場契約,ルート契約,池契約のABIを登録し,いくつかのテストを行いました.factory方法がすべて戻りました0x1F98431c8aD98523631AE4a59f267346ea31F984この住所は,Uniswapの工場契約 (コード) の住所ですcontractV3FactoryAddress変数) のアドレスである.

var contractV3FactoryAddress = "0x1F98431c8aD98523631AE4a59f267346ea31F984"

ABIでスマートコントラクトを登録し,次に,ABIでスマートコントラクトを使用する方法を調べます.Uniswap V3変換操作は,次のようにします.ERC20暗号通貨の交換 (イーサリアン上で) が具体的シーンとして用いられる.

問い合わせUniswap V3路線契約の許可

ニュースERC20契約書には,allowanceこの関数は,他のアドレスに授与されたトークンの数を問い合わせる.特定のアドレスが別のアドレス (通常は契約アドレス) に授与されたトークンの数を自分のアカウントから転送できるかを問い合わせる. についてUniswap V3ルーティング契約は,あなたが実行している場合は,approveルーティング契約のアドレスを指定します.ERC20トークンallowanceライセンス数を求める関数です.

このビデオでは,この2つの要素がERC20契約方法の呼び出しか?allowance、approveありがとうございましたERC20契約の方法,これらの方法は,私たちが前に説明したものです.balanceOf、transfer方法が平等である.

交換する前に,最初に確認する必要があります.Uniswap交換を行うのに十分な数のトークンをルートを契約します.1INCH->ETH料金設定は1万です. この料金設定は1万で,1パーセントの料金を表示します.Uniswap交換池には様々な料金があります.Uniswap設定されたいくつかのオプション.例えば,料金は3000に設定され,料金は0.3%を表す.Uniswap文書,関連情報.

換算池は1INCH/WETHETHとWETHは,イーサリアムにおける2つの異なるトークンである.

• ETH (イーサリング): ETHは,イーサリアム・ブロックチェーンのネイティブ暗号通貨であり,イーサリアム・ネットワークの主要な資産と計算単位である.ETHは,イーサリアム・ネットワーク上のネイティブ・トークンであり,普遍的な流通性と利用性があり,取引手数料の支払い,スマートコントラクトの相互作用,価値の貯蔵などに使用できる.
• WETH (包装されたイーサリング): WETHは,ETHをERC20標準トークンに包装する形式である.これは,ETHがERC20トークンとスマートコントラクトでシームレスに相互作用できるようにするEthereum上のスマートコントラクトである.WETHは,ETHをWETHのコントラクトアドレスに保存して作成および取得することができ,いつでもWETHをETHに変換することができます.EthereumエコシステムにおけるWETHの主な役割は,ETHに他のERC20トークンと同じ標準インターフェースと互換性を提供し,ETHが分散取引,流動池,および他のDeFiプロトコルに参加できるようにすることです.

したがって,WETHは,ETHをEthereumスマートコントラクトでERC20トークンとしてやり取りできるようにする包装形式である.典型的には,スマートコントラクトでETHを使用する必要がある場合,ETHをWETHに変換し,取引またはDeFi操作に参加し,その後,必要に応じてWETHを再びETHに変換することができます.

使用するERC20ありがとうございました.allowanceライセンス取得の方法:
