Can help me to execute this same code in ethers.js

davidzuccarini · December 26, 2022, 1:29pm

I use moralis for an authentication by mail and ethers to transact in another way with another login to be able to sign the transactions. The question is if you are so kind to help me

I must pass the code to execute the function from morales to ethers to be able to sign, I share the code of what I have tried, there are more things that I have tried:

const sendOptions = {

        contractAddress: tokenAddress.toString().toLowerCase(),

        functionName: "createItem",

        abi: tokenErc721,

        params: {

          _req: [

          user.get("ethAddress"),

          user.get("ethAddress"),

          parseFloat(royal) * 2000,

          user.get("ethAddress"),

          metadataUrl,

          0,

          contracts.token,

          '0',

          '0',

          '0x0000000000000000000000000000000000000000000000000000000000000000'

        ],

        },

      };
        const tx: any = await Moralis.executeFunction(sendOptions)
        const result = await tx.wait(1);

need the same result but signing it with a custom signer i’m trying this way:


async function mintNFTEmail(metadataUrl: string, tokenAddress:  string) {

   

    const ethers = Moralis.web3Library;

    const mnemonic = userRender.attributes?.mnemonic ? userRender.attributes.mnemonic : "";

    const userAddress = userRender.attributes?.ethAddress.toString().toLowerCase() ? userRender.attributes.ethAddress : "";

    const ethAddress = userRender.attributes?.ethAddress ? userRender.attributes.ethAddress.toString().toLowerCase() : "";

    console.log("🚀 ~ file: MintState.tsx:655 ~ mintNFTEmail ~ ethAddress", ethAddress)

    const privateKey = userRender.attributes?.privateKey

    ? userRender.attributes.privateKey

    : "";

    const contractTokenKNRT = contracts.token;

    const contractERC721 = contracts.auction;

    const collectionAddress = tokenAddress.toLowerCase()

    const provider = new ethers.providers.WebSocketProvider("wss://polygon-mumbai.g.alchemy.com/v2/F1K_GUpFYDTcyNtye1IA7kPc_ant5-EH")

    // const provider = new ethers.providers.JsonRpcProvider(`${urlProvider}${apiAlchemy}`)

   

    console.log('providesAlchemy', `${urlProvider}${apiAlchemy}`)

    console.log("🚀 ~ file: MintState.tsx:663 ~ mintNFTEmail ~ provider", provider)

    // const signer = new ethers.Wallet(privateKey, provider);

       

    const wallet = ethers.Wallet.fromMnemonic(mnemonic);

    const signer = wallet.connect(provider);

    console.log("🚀 ~ file: MintState.tsx:665 ~ mintNFTEmail ~ signer", signer)

    let royal = 20 * 1000;

    if (userAddress) {

      const sendOptions = {

        contractAddress: tokenAddress.toString().toLowerCase(),

        functionName: "createItem",

        abi: tokenErc721,

        params: {

          _req: [

          ethAddress,

          ethAddress,

          royal,

          ethAddress,

          metadataUrl,

          0,

          contractTokenKNRT,

          '0',

          '0',

          '0x0000000000000000000000000000000000000000000000000000000000000000'

        ],

        },

        signer: signer

      };

      const _req =  [

            ethAddress,

            ethAddress,

            royal,

            ethAddress,

            metadataUrl,

            0,

            contractTokenKNRT,

            '0',

            '0',

            '0x0000000000000000000000000000000000000000000000000000000000000000'

          ]

      try {

        // const contract = new ethers.Contract(collectionAddress, tokenErc721, signer);

        // const contract = new ethers.Contract(collectionAddress, tokenErc721, signer);

        // console.log("🚀 ~ file: MintState.tsx:697 ~ mintNFTEmail ~ contract", contract)

        const hola = await wallet.signTransaction(sendOptions, privateKey)

        console.log("🚀 ~ file: MintState.tsx:725 ~ mintNFTEmail ~ hola", hola)

       

        // const tx = await contract.connect(signer).deploy(

        //   // sendOptions

        //   _req

        // ).wait(3);

       

        // const data = Promise.resolve(tx)

        // data.then(value => {

        //   console.log('dataPromise', value)

        // });

        // console.log("🚀 ~ file: MintState.tsx:722 ~ mintNFTEmail ~ data", data)

        // console.log("🚀 ~ file: MintState.tsx:698 ~ mintNFTEmail ~ tx", tx)

        // const tx: any = await Moralis.executeFunction(sendOptions)

        // const result = await tx.wait(1);

        console.log("resultMintNFT ", JSON.stringify(hola))

        console.log("resultMintNFTJSON", JSON.stringify(parseInt(hola.events[1].args[1]._hex, 16).toString()))

        return parseInt(hola.events[1].args[1]._hex, 16).toString()

      }catch (e: any) {

        console.log("ErrorMintNFT1", e)

        console.log("ErrorMintNFT2", e.message)

        return "-1";

      }

    }

  }

note: What is commented is what I have tried

and the same applies to this function, how can I take it to ethers:

async function _onBuy() {

    const user = await Moralis.User.current();

    if (user) {

      try {

        console.log(Moralis.Units.ETH(price));

        const sendOptions2 = {

          contractAddress: "0x11142365DDbc92C3547b8A074289409B5432CA8b",

          functionName: "approve",

          abi: abi.token,

          awaitReceipt: true, // should be switched to false

          params: {

            spender: "0xE76Bc6E52C2Db6054C4E63f2C9e72ADE240AC3DE",

            amount: Moralis.Units.ETH(price),

          },

        };

        let res = await Moralis.executeFunction(sendOptions2);

        await res.wait(2);

        const sendOptions = {

          contractAddress: "0xE76Bc6E52C2Db6054C4E63f2C9e72ADE240AC3DE",

          functionName: "makeBid",

          abi: abi.marketplace22,

          awaitReceipt: true,

          params: {

            _nftContractAddress: tokenAddress,

            _tokenId: tokenId,

            _erc20Token: "0x11142365DDbc92C3547b8A074289409B5432CA8b",

            _tokenAmount: price,

          },

        };

        const addItemToMarket = await Moralis.executeFunction(sendOptions);

        await addItemToMarket.wait(2);

      } catch (err: any) {

        console.log(err.message);

      }

    } else {

      return;

    }

  }

note: In the first one I need to sign and execute that function and in the other the same but also sign the payment

error example console.log:

what line gives that error?

this is the error:

**this code error **

alex · December 21, 2022, 7:05pm

Can you find out the actual line of code where this error is coming from? Maybe you are not passing the right value - where did you get all this code from?

davidzuccarini · December 21, 2022, 8:57pm

I have taken the code from the documentation examples, with moralis there is no problem it works, the problem is that I want to migrate the code to ethers js from excuteFunction from moralis to ethers js to sign transactions with a custom wallet not by metamask.

the incoming values to the function are correct debug in the console.log, could you help me with an example of converting this function from moralis

const sendOptions = {

        contractAddress: tokenAddress.toString().toLowerCase(),

        functionName: "createItem",

        abi: tokenErc721,

        params: {

          _req: [

          user.get("ethAddress"),

          user.get("ethAddress"),

          parseFloat(royal) * 2000,

          user.get("ethAddress"),

          metadataUrl,

          0,

          contracts.token,

          '0',

          '0',

          '0x0000000000000000000000000000000000000000000000000000000000000000'

        ],

        },

      };


         const tx: any = await Moralis.executeFunction(sendOptions)
        const result = await tx.wait(1);

for the same function but with a signer in ethers js

davidzuccarini · December 21, 2022, 9:01pm

in the same way with a payment function:

        const sendOptions2 = {
          contractAddress: "0x11142365DDbc92C3547b8A074289409B5432CA8b",
          functionName: "approve",

          abi: abi.token,
          awaitReceipt: true, // should be switched to false
          params: {
            spender: "0xE76Bc6E52C2Db6054C4E63f2C9e72ADE240AC3DE",
            amount: Moralis.Units.ETH(price),
          },
        };

        let res = await Moralis.executeFunction(sendOptions2);
const sendOptions = {

          contractAddress: "0xE76Bc6E52C2Db6054C4E63f2C9e72ADE240AC3DE",

          functionName: "makeBid",

          abi: abi.marketplace22,

          awaitReceipt: true,

          params: {

            _nftContractAddress: tokenAddress,

            _tokenId: tokenId,

            _erc20Token: "0x11142365DDbc92C3547b8A074289409B5432CA8b",

            _tokenAmount: price,

          },

        };
        const addItemToMarket = await Moralis.executeFunction(sendOptions);
        await addItemToMarket.wait(2);

how convert 2 function moralis in ethers js with custom signer if i have a private key or mnemonic

alex · December 21, 2022, 11:11pm

You can create a wallet instance.

alex · December 24, 2022, 9:12pm

These two Moralis functions you want to migrate work? executeFunction() uses ethers.js under the hood, so it will work more or less in the same way. There is an example here for interacting with contracts with ethers.js.

Where is this warning from? It doesn’t seem related to contract interaction.

davidzuccarini · December 26, 2022, 9:46pm

I already removed that error, the error is that the transaction options do not grab me, Yes, with the moralis function everything works perfectly, the problem is executing the same function but with ethers the options don’t grab me this error gives me right now.

Please look at the code, the examples that you gave me, I already tried it that way and in others, but it does not take the options to execute or it tells me invalid values or it stays waiting in the transaction and does nothing.

        console.log("ErrorMintNFT2", e.message)

        return "-1";

      }

  }

and in this way I get this result but how do I get the token id because with tokenId.events[1].args[1]._hex, 16 I don’t get anything

this it result :

johnversus · December 28, 2022, 6:32am

You can run the wait() function in your result to get the transaction logs from the confirmed transactions.

Once you have the logs you can use ether js to decode the data from transaction logs.

let abi = [ ];
let interface = new ethers.utils.Interface(abi)

// logs is an array from the confirmed transaction object
logs.forEach((log) => {
    console.log(interface.parseLog(log));
});

davidzuccarini · December 29, 2022, 5:06am

I think I have not explained myself well or they do not understand the question, I explain again, the problem is that the transaction is never sent to the blockchain if I get into

As an example of one of the collections created, the transaction is not generated. I cannot wait for the transaction because it is not executed. I am doing something wrong that does not send the transaction. I am not successful in generating the transaction. This is the last code I have, sorry. the disaster of the code but I exhaust all the solutions so that the transaction is sent the result of the code below gives me an error, first I put the code of the function and last the error. thanks for the patience.

This is what the contract function receives:

Can you try adding some logs to check if any of the param addresses are undefined or invalid?

davidzuccarini · December 29, 2022, 7:46pm

Yes, all the fields are verified and have their value, I think the error is how the parameters are passed to the function.
