FMZ を使用してEthereumをベースにした web3 開発を簡単に開始する

This section uses the ```Goerli``` testnet environment.
#### balanceOf
Next, let's practice again how to call the ```Read``` method of a contract to read contract information, call the ```balanceOf``` method of ERC20 contract to query token balance, the balanceOf method has only one parameter, which is not named, but can be identified by its type as an address (i.e., the address of the token being queried). Since the returned data is not in units of one token, we also need the precision data of tokens for conversion. The precision of tokens can be obtained by using ```decimals``` method in ERC20 contracts. We will use Ethereum testnet ```goerli``` for testing. Please note that token contract addresses may vary on different chains.
```javascript
function toAmount(s, decimals) {
return Number((BigDecimal(BigInt(s)) / BigDecimal(Math.pow(10, decimals))).toString())
}
function main() {
let walletAddress = exchange.IO("address")
// goerli WETH address
let wethAddress = "0xB4FBF271143F4FBf7B91A5ded31805e42b2208d6"
// goerli LINK address
let linkAddress = "0x326C977E6efc84E512bB9C30f76E30c160eD06FB"
// Since it is an ERC20 contract, FMZ has built-in ABI registration, so there is no need to register ERC20 ABI here.
let wethDecimals = exchange.IO("api", wethAddress, "decimals")
let linkDecimals = exchange.IO("api", linkAddress, "decimals")
let wethBalance = exchange.IO("api", wethAddress, "balanceOf", walletAddress)
let linkBalance = exchange.IO("api", linkAddress, "balanceOf", walletAddress)
Log("WETH precision:", wethDecimals, "wethBalance:", toAmount(wethBalance, wethDecimals))
Log("LINK precision:", linkDecimals, "linkBalance:", toAmount(linkBalance, linkDecimals))
}
このコードを実行すると,現在のウォレット
WETH 精度: 18th バランス: 0 LINK精度: 18リンク バランス: 51.41374973681053

次に,WETHトークンの ERC20 スマートコントラクトとやり取りを続けます. 今回は,書き込みタイプ方法を呼びます.deposit- わかった
機能についてdepositWETH にある一定量のETH を交換するだけです.depositABI を調べることで確認できます.payableこのメソッドの属性はtrueETH (payableAmount) の金額を指定します. ETHの金額を指定するには,ETH (payableAmount) の金額を指定する必要があります.
スマートコントラクトのメソッドを呼び出すときに注意してください: 呼び出しメソッドが支払いの属性を持っている場合,あなたは転送ETH値を追加する必要があります (メソッドの4番目のパラメータ)exchange.IOfunction) は,数値型または数値値の文字列形式の方法名の後ろに表示される.

WETHとETHのバランスを再確認します.

呼び出す前にdeposit, WETH0 とETH0.14333094664072302です. 電話した後,deposit, WETH0.01 で,ETH0.01 を交換していることがわかります.ETHについてWETH successfully.
移転
ERC20トークンは,transferアドレスに0.01 WETHトークンを転送する方法0x4D75a08E870674E68cAE611f329A27f446A66813.....transfer方法には2つのパラメータがあります.dst送金受取者の財布アドレスで,第2パラメータwad送金金額です

0.01 は 0.01 に等しいです.WETH交換されたETH.
ユニスワップ V3
Uniswap V3エサリアム・ブロックチェーンに構築された分散型取引プロトコルで,暗号通貨取引と流動性提供を促進するために使用されます.コアコントラクト,プールコントラクト,工場コントラクト,ルーターコントラクトなど,一連のスマートコントラクトで構成されています.
下記の契約は,主に現在の為替価格を問い合わせ,およびUniswap:
Router(ルーター契約) この契約は,取引を実行するために使用され,ユーザが取引経路とパラメータを指定して取引を行うことができる.Pool(プール契約) プール契約はUniswap特定の資産ペアの流動性を保管および管理する.各資産ペアには,流動性プロバイダーが提供する資金,価格範囲,手数料設定等に関する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,取引の処理,プールの状態の計算,取引のスムーズな実行を保証します.Factory(工場契約) 工場契約は,製造と管理に使用される契約です.Uniswapプール契約.ユーザーが新しい資産ペアを作成したいとき,ファクトリー契約との相互作用によって新しいプール契約を展開する.ファクトリー契約は,プール契約の作成と初期化を調整し,ユーザーが動的に新しい資産ペアを作成できるようにする.
先のレッスンで学んだように,どのように登録するか見直しましょう.ABIFMZ 量子取引プラットフォームの戦略コードでスマートコントラクトのABIを取得するプロセスは,以前のレッスンで議論されており,ここで繰り返しません.

上記のコードは,工場契約,ルーター契約,プール契約のABIを登録し,いくつかのテストを行いました.factoryルーター契約とプール契約の両方の方法 アドレスを返します0x1F98431c8aD98523631AE4a59f267346ea31F984, これは Uniswap 工場契約のアドレス (変数contractV3FactoryAddressコードに記載されている)
var contractV3FactoryAddress = "0x1F98431c8aD98523631AE4a59f267346ea31F984"
次に,スマートコントラクトのABIを登録した後,Uniswap V3交換します. そして,次にERC20トークン (Ethereum メインネット) を特定のシナリオとして
問い合わせUniswap V3ルーター契約の承認
についてallowanceこの関数は,ERC20特定のアドレスが他のアドレス (通常は契約アドレス) に権限を与えたトークンの数を問い合わせ,そのアカウントから転送することができます.
についてUniswap V3実行している場合は,approveルーター契約へのアドレスを許可するには,allowance機能についてERC20その権限の番号を問い合わせるためのトークンです
呼び出しを覚えているERC20契約方法
