Prefácio

No campo das transações de blockchain, as exchanges descentralizadas (DEX) fornecem uma maneira confiável de trocar ativos, e a SunSwap, como uma DEX representativa no ecossistema Tron, oferece suporte a interações de contratos inteligentes baseadas na Web3. A plataforma FMZ (FMZ Quantitative) fornece uma poderosa estrutura de negociação quantitativa que permite aos desenvolvedores integrar diversas estratégias de negociação.

A plataforma FMZ já suporta o encapsulamento de objetos de troca Web3 Ethereum (ETH) e recentemente adicionou suporte para Web3 TRON, encapsulando os objetos de troca da cadeia TRON. Assim como acessar o UniSwap DEX, o acesso ao SunSwap DEX também pode ser obtido.

Este artigo explorará como encapsular a interface Web3 com base na plataforma quantitativa FMZ e se conectar ao SunSwap DEX para transações. Apresentaremos o método de interação Web3 da rede Tron, a chamada de contrato inteligente SunSwap e mostraremos por meio de exemplos de código como consultar liquidez, executar transações e obter resultados de transações, para construir uma estratégia de negociação quantitativa eficiente.

declaração

Todos os códigos e designs compartilhados neste artigo foram testados e são destinados ao aprendizado e à comunicação. Entretanto, mesmo após os testes, talvez seja necessário ajustá-los com base nas necessidades reais. Se você precisar aplicá-lo em negociações reais, certifique-se de avaliá-lo, otimizá-lo e modificá-lo você mesmo para garantir que ele atenda às suas próprias necessidades.

Preparação

• Configurar o objeto de troca Web3 TRON da plataforma FMZ

No artigo anterior「Expansão FMZ Quantitative Web3: Adicione suporte Tron e expanda as capacidades de transação on-chain」Neste artigo apresentamosTron gRPC Aprendemos os métodos comuns de configuração de nós e como configurar o objeto de troca Web3 TRON no FMZ. Este artigo não repetirá esses conteúdos. Quanto ao endereço do nó, usaremos diretamente o nó fornecido oficialmente pelo TRON.

• Implantar o host

https://www.bilibili.com/video/BV1PC4y1F7TN/

Ao contrário das bolsas CEX, não há barreiras com as quais se preocupar. Você pode acessar o nó oficial implantando um host localmente.

• SunSwap DEX

https://sun.io/

Abra a página inicial do SunSwap no navegador, você pode se conectar à carteira e observar os dados convenientemente.

• tronscan

https://tronscan.org/

Ferramentas essenciais para visualizar e analisar dados.

• base58

Os endereços no TRON são codificados em base58, o que é diferente do Ethereum. Às vezes, alguma conversão é necessária para visualizar e comparar dados. Na FMZ, você pode usar diretamente endereços codificados em base58. Alguns contratos inteligentes retornam dados em codificação HEX, o que requer alguma conversão. Várias funções são implementadas de forma simples para converter formatos de endereço:

A seguir estão as principais funções de conversão. Devido ao espaço limitado, não postarei todos os códigos. O código completo está na biblioteca de modelos “Tron SunSwap V3 Trading Library” divulgada no final do artigo.

  function ethAddressToTron(ethAddress) {
      if (!/^0x[0-9a-fA-F]{40}$/.test(ethAddress)) {
          throw "Invalid Ethereum address"
      }

      const ethAddressBytes = new Uint8Array(20)
      for (let i = 0; i < 20; i++) {
          ethAddressBytes[i] = parseInt(ethAddress.substr(2 + i * 2, 2), 16)
      }

      const tronAddressBytes = new Uint8Array(21)
      tronAddressBytes[0] = 0x41
      tronAddressBytes.set(ethAddressBytes, 1)

      const hash1 = Encode("sha256", "hex", "hex", uint8ArrayToHex(tronAddressBytes))
      const hash2 = Encode("sha256", "hex", "hex", hash1)
      const checksum = hash2.slice(0, 8)

      const fullAddress = new Uint8Array(25)
      fullAddress.set(tronAddressBytes, 0)
      fullAddress.set(hexToUint8Array(checksum), 21)

      return base58Encode(fullAddress)
  }

• Chamada de pacote

Como às vezes você precisa ler dados de vários métodos ao mesmo tempo, chamá-los um por um é demorado e trabalhoso. Então uma função de chamada empacotada é encapsulada:

  function multicall(e, multicallContractAddress, data, outTypes) {
      let ret = e.IO("api", multicallContractAddress, "aggregate", data)
      if (!ret || !ret["returnData"] || !Array.isArray(ret["returnData"])) {
          Log("invalid ret:", ret)
          return null
      }

      let arrRet = ret["returnData"]
      if (outTypes.length != arrRet.length) {
          Log("Arrays have unequal lengths:", arrRet, outTypes)
          return null
      }

      let outData = []
      for (let i in arrRet) {
          outData.push(e.IO("decode", outTypes[i], arrRet[i]))
      }

      return outData
  }

Biblioteca de negociação Tron SunSwap V3

O design da biblioteca de negociação SunSwap V3 é modelado com base no modelo de biblioteca de negociação UniSwap da plataforma FMZ. Como o código do modelo SunSwap é relativamente longo, não o publicarei aqui, mas explicarei principalmente as funções implementadas.

Criar objeto de transação SunSwap

let e = $.CreateSunSwapEx()                 // 默认使用exchange即exchanges[0]初始化SunSwap交易对象。
// let e = $.CreateSunSwapEx(exchanges[1])  // 使用次交易所对象初始化SunSwap交易对象。

Este modelo tem apenas uma função de interface, a saber:$.CreateSunSwapEx()Usado para criar objetos de transação SunSwap. Após a criação do objeto, você pode chamar o método deste objeto para fazer algumas chamadas funcionais, como: transações de resgate, consultar preços do pool, obter todas as informações do pool V3, penhor, descompressão, etc.

GetMarkets

O código de teste da “Tron SunSwap V3 Trading Library” está no modelomain()A função foi gravada e não será repetida aqui.

    let markets = e.GetMarkets()
    let idx = 0
    let tbl = {"type": "table", "title": "test GetMarkets", "cols": ["Index", "PoolAddress", "Symbol", "BaseAsset", "QuoteAsset", "BaseName", "QuoteName", "BaseDecimals", "QuoteDecimals", "BaseAddress", "QuoteAddress"], "rows": []}
    for (let currency in markets) {
        let arrMarket = markets[currency]
        for (let market of arrMarket) {
            tbl["rows"].push([idx, market["PoolAddress"], market["Symbol"], market["BaseAsset"], market["QuoteAsset"], market["BaseName"], market["QuoteName"], market["BaseDecimals"], market["QuoteDecimals"], market["BaseAddress"], market["QuoteAddress"]])    
            idx++
        }
    }
    LogStatus("`" + JSON.stringify(tbl) + "`")

funçãoGetMarkets()Usado para obter informações relevantes de todos os pools de troca do pool SunSwap V3, armazenados em cache nas variáveis ​​dos objetos de transação do SunSwap e usados ​​para consultar precisão, endereço e outras informações durante outras operações.

Este código de teste exibirá informações sobre todos os pools V3 após a execução:

Alguns dos endereços de contrato, como “contratos de phishing” e “contratos inválidos”, que foram vistos até agora foram removidos do código.

GetTicker

    let ticker1 = e.GetTicker("WTRX_USDT")
    Log("symbol:", "WTRX_USDT", ", ticker:", ticker1)
    let ticker2 = e.GetTicker("iCMX_USDT", "TLVDozYEBgeaJXH7oKBsougzEJKNrogFun")  // iCMX_USDT
    Log("symbol:", "iCMX_USDT", ", ticker:", ticker2)

DisponívelGetTicker()A função consulta o preço de um determinado pool de câmbio e pode especificar o endereço de um pool específico. Observe que alguns pools têm liquidez muito baixa e os preços são apenas para referência.

multicall

    let data = []
    let walletAddress = exchange.IO("address")
    data.push(["TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t", "0x" + exchange.IO("encode", "TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t", "balanceOf", walletAddress)])    
    data.push(["TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t", "0x" + exchange.IO("encode", "TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t", "balanceOf", walletAddress)])    
    Log(data)
    let ret = multicall(exchange, "TGXuuKAb4bnrn137u39EKbYzKNXvdCes98", data, ["uint256", "uint256"])
    Log(ret, toAmount(ret[0], 6))

Esta função pode ser usada para encapsulamento de funções subsequente. Por exemplo, no exemplo, você pode colocarbalanceOfA chamada do método é codificada e os dados são solicitados uma vez.

GetSwapOutAmount

    let retBuy = e.GetSwapOutAmount("WTRX_USDT", 1, "buy")     // 1 quote -> base
    Log("WTRX_USDT", "buy outAmount:", retBuy["outAmount"], ", ask:", (1 / retBuy["outAmount"]))
    let retSell = e.GetSwapOutAmount("WTRX_USDT", 1, "sell")   // 1 base -> quote
    Log("WTRX_USDT", "sell outAmount:", retSell["outAmount"], ", bid:", (retSell["outAmount"] / 1))

Esta é uma função relativamente importante, que encapsula o serviço de roteamento inteligente do SunSwap. Dados tokenInSymbol e tokenOutSymbol, ele pode retornar possíveis caminhos de troca, o número de tokens de saída e outras informações.

GetAssets

    let assets = e.GetAssets()
    let tbl = {"type": "table", "title": "test GetAssets", "cols": ["Name", "Address", "Decimals", "Balance"], "rows": []}   
    for (let asset of assets) {
        tbl["rows"].push([asset.Currency, asset.Address, asset.Decimals, asset.Amount])
    }
    LogStatus("`" + JSON.stringify(tbl) + "`")

Como não há um bom mecanismo para percorrer tokens TRC20, com a ajuda da travessia do tronscan, essa interface de terceiros é usada para consultar informações de ativos da conta.

Swap

    // 6 USDT -> ? WTRX
    let ret = e.Swap("WTRX_USDT", 6, "buy")
    Log(ret)

    // 10 TRX -> ? WTRX
    // let ret = e.Swap("TRX_WTRX", 10, "sell")
    // Log(ret)

A função mais importante é essa troca. Ao executar a troca, o caminho de troca será formulado de acordo com o roteamento inteligente e, então, o método de troca será chamado para trocar os tokens. Observe que, se for uma troca de embalagem/desembalagem TRX, ela só será executada usando o método de contrato WTRX.

Existem algumas outras funções que podem ser adicionadas ao código do modelomain()Função, não vou entrar em detalhes.

Código do modelo

Este modelo não possui nenhumDesign de interaçãoeParâmetros de interface, ele realiza apenas a função básica de acessar o SunSwap DEX, e mais funções podem ser otimizadas e adicionadas no futuro.
