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))
}

Durch Ausführen des obigen Codes können Sie den aktuellen Wallets WETH- und LINK-Token-Guthaben abfragen:

Einzahlung

Wir können sehen, dass das Gleichgewicht der WETH-Token in der Brieftasche 0 beträgt. Als nächstes werden wir mit dem ERC20-Smart-Vertrag von WETH-Token interagieren, und diesmal werden wir die Methode des Schreibtyps aufrufen:deposit- Ich weiß. Die Funktion derdepositEs sollte darauf hingewiesen werden, dass es keine Parameter für diedepositDie Ergebnisse der Untersuchung wurden in derpayableAttribut dieser Methode isttrue, so dass Sie beim Anrufen die übertragbare ETH (PayableAmount) Menge festlegen müssen, um den ETH-Einzahlungsbetrag anzugeben.

Achten Sie beim Anrufen von Smart Contract Methoden auf: Wenn die aufgerufene Methode ein zahlbares Attribut hat, müssen Sie einen Transfer ETH-Wert (der vierte Parameter derexchange.IOFunktion) nach dem Methodennamen, der eine numerische Art oder eine Zeichenfolge mit einem numerischen Wert sein kann.

Übertragung

ERC20-Token können auch übertragen werden, indemtransferMethode zur Übertragung von 0,01 WETH-Token an die Adresse0x4D75a08E870674E68cAE611f329A27f446A66813. DietransferDie Methode hat zwei Parameter, der erste Parameterdstist die Wallet-Adresse des Überweisungsempfängers und der zweite Parameterwadist der Übertragungsbetrag.

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) {
    for (var i = 0 ; i < 10 ; i++) {
        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)
    }
    return false 
}

function main() {
    let walletAddress = exchange.IO("address")
    
    // goerli WETH address 
    let wethAddress = "0xB4FBF271143F4FBf7B91A5ded31805e42b2208d6"

    // Since it is an ERC20 contract, FMZ has built-in ABI registration, there is no need to register ERC20 ABI here.
    let wethDecimals = exchange.IO("api", wethAddress, "decimals")
    let wethBalance = exchange.IO("api", wethAddress, "balanceOf", walletAddress)
    Log("WETH precision:", wethDecimals, "wethBalance:", toAmount(wethBalance, wethDecimals))

    let dst = "0x4D75a08E870674E68cAE611f329A27f446A66813"
    let wad = toInnerAmount(0.01, wethDecimals)

In dem obigen Beispiel, eine benutzerdefinierte FunktionwaitMinedWir sind nicht unbekannt mit der Funktion dieser Funktion.eth_getTransactionReceiptDer Zweck dieser waitMined benutzerdefinierten Funktion ist es, auf das Ergebnis des passierten Transaktions-Hashs zu warten.

Rückzug

Dieses Mal tauschen wirWETHZurück zuETH, unter Verwendung derwithdrawMethode, die nur einen Parameter hatwad, einfach gesagt, wird es verwendet, um festzulegen, wie viel ETH zurückgetauscht werden soll.

Aus dem obigen Code kann man sehen, dass es im Grunde das gleiche wie im vorherigen Beispiel ist, mit der Ausnahme, dass die im letzten Schritt aufgerufene Methode geändert wirdwithdraw, bevor Sie anrufen:

WETH-Genauigkeit: 18 WethBalance: 0,01 ETH-Genauigkeit: 18 ethBalance: 0,11322979983231546

Noch eine Frage:

WETH-Genauigkeit: 18 WethBalance: 0 ETH-Genauigkeit: 18 ethBalance: 0,1231207156449464

Wir können sehen, dass 0.01WETHwurde zurück inETH.

Uniswap V3

Uniswap V3ist ein dezentrales Transaktionsprotokoll, das auf der Ethereum-Blockchain aufgebaut wurde und zur Erleichterung des Kryptowährungshandels und der Liquiditätsversorgung verwendet wird.

Die folgenden Verträge werden hauptsächlich bei der Abfrage des aktuellen Wechselkurses und bei der Durchführung von Wechselkursgeschäften mitUniswap:

• Router(Routervertrag) Dies ist der Vertrag, der zur Durchführung von Transaktionen verwendet wird und dem Benutzer erlaubt, eine Handelsoperation durch Angabe eines Handelsweges und Parameter durchzuführen.
• Pool(Poolvertrag) Der Schlüsselbestandteil derUniswapFür die Speicherung und Verwaltung der Liquidität eines gegebenen Vermögenspaares. Jedes Vermögenspaar hat einen entsprechenden Poolvertrag, der Informationen über die vom Liquiditätsanbieter bereitgestellten Mittel, Preisspanne, Gebühren-Einstellungen usw. enthält. Der Poolvertrag ist für die Abwicklung von Transaktionen, die Berechnung des Status des Pools und die Gewährleistung der reibungslosen Abwicklung von Transaktionen verantwortlich.
• Factory(Werksvertrag) Fabrikverträge sind die Verträge, die zur Erstellung und VerwaltungUniswapWenn Benutzer neue Assetpaare erstellen möchten, setzen sie neue Poolverträge ein, indem sie mit dem Fabrikvertrag interagieren. Fabrikverträge sind für die Koordinierung der Erstellung und Initialisierung von Poolverträgen verantwortlich und ermöglichen es Benutzern, neue Assetpaare dynamisch zu erstellen.

Wie wir in den vorangegangenen Lektionen gelernt haben, wollen wir nun überprüfen, wie dieABIDer Prozess der Erlangung des ABI von Smart Contracts wurde in früheren Lektionen diskutiert und wird hier nicht wiederholt. Drei.UniswapSmart-VertragABIs müssen registriert werden, wobei das Ethereum-Mainnet als Beispiel verwendet wird:

Der oben genannte Code registrierte die ABI des Fabrikvertrags, des Routervertrags und des Poolvertrags und führte einige Tests durch.factoryMethode sowohl des Routervertrags als auch des Poolvertrags gibt die Adresse zurück0x1F98431c8aD98523631AE4a59f267346ea31F984, die die Adresse des Uniswap-Werkvertrags (VariablecontractV3FactoryAddressin dem Code).

Nach der Registrierung der ABI des Smart Contracts schauen wir uns als Nächstes den Austauschvorgang mitUniswap V3Erstens, und in den folgenden verwenden wir den Austausch vonERC20Token (im Ethereum-Mainnet) als spezifisches Szenario.

AbfrageUniswap V3Autorisierung des Routervertrags

DieallowanceFunktion wird in derERC20Es stellt die Anzahl der Token ab, die eine bestimmte Adresse an eine andere Adresse (normalerweise die Vertragsadresse) autorisiert hat, die von ihrem eigenen Konto übertragen werden kann. FürUniswap V3Routerverträge, wenn Sie bereits dieapproveFunktion, um eine Adresse zu einem Router-Vertrag zu autorisieren, dann können Sie dieallowanceFunktion derERC20Token, um die Nummer dieser Genehmigung abzufragen.

Erinnern Sie sich an den Anruf an dieERC20Vertragsmethode d
