I have a problem with a smart contract transaction between users. Error: gas is missing.

Here is my function:


async function transactionContract() {
  
  let signerAddress = gettingOwnerByKey(
    "privateKey"
  ).address;

 
  let addressRecipient = "0x82A8AD5c429903c082686a307083330F99c40E53";

  const escrow = new web3.eth.Contract(
    ABI2,
    "0xF36198Ce8Dfe6A5694541bb1604195A7b9E2A61D",
    {
      from: "0x061A96C2b5A18b132783bF65a45BC720e6C95b2A",
    }
  );
  const NET_ID = "35855456";

 
  let tx = await escrow.methods.shifting(addressRecipient).encodeABI({
    chainId: NET_ID,
    gas: "320000",
    gasPrice: web3.utils.toWei("42", "gwei"),
    nonce:  web3.eth.getTransactionCount(signerAddress, "pending"),
  });


  const signedContract = await web3.eth.accounts.signTransaction(
    tx,
    "privateKey"
  );

 
  const transactionSignature = await web3.eth.sendSignedTransaction(
    signedContract.rawTransaction
  );
  console.log(transactionSignature)
}

I cannot understand why it will result in an error - "gas is missing"!

  • What line does cause such error message? The call to getTransactionCount is missing await. – Ismael Jan 7 at 4:50
  • ` const signedContract = await web3.eth.accounts.signTransaction( tx, "privat key" );` error here – Artem Strekalov Jan 7 at 8:31
  • Why are you assigning to tx the result of encodeABI()? Also it doesn't accept any parameter. Probably you wanted to do something like let tx = { <other fields>, data: await escrow.methods.shifting(addressRecipient).encodeABI() } instead. – Ismael Jan 7 at 15:57
  • If I write instead of encodeABI () - send (), an error pops up: "Unknown account". Tx should return data object? I did as you said, as a result, tx returns an object. But the promise also returns an error: [[PromiseResult]]: Error: "gas" is missing at _validateTransactionForSigning – Artem Strekalov Jan 8 at 10:20
  • What are you trying to do, send a transaction or sign a transaction? If you output tx before signing what does it look like? Try writing gas as an hexadecimal string web3.utils.toHex("3200"). – Ismael Jan 8 at 14:00

The following worked for me

const recipient = new web3.eth.Contract(<ABI>, <address>);

const nonce = await web3.eth.getTransactionCount(signerAddress, "pending");
const data = recipient.methods.deposit(4444).encodeABI();

const txData = {
    chainId: web3.utils.toHex('35855456'),
    nonce,
    from: signerAddress,
    gasPrice: web3.utils.toWei("42", "gwei"),
    gas: web3.utils.toHex('320000'),
    to: recipient.options.address,
    value: '0x',
    data
};

const tx = await web3.eth.accounts.signTransaction(txData, privateKey);

await web3.eth.sendSignedTransaction(tx.rawTransaction);

const id = await recipient.methods.id().call();

console.log(`Id: ${id}`);

Where my test contract is

pragma solidity ^0.7.0;

contract Recipient {
  uint public id;

  function deposit(uint _id) public payable {
    id = _id;
  }
}

  • I am the owner of a smart contract, I need to transfer the ownership of my smart contract to another wallet. I tried to do it according to your example, the transaction hash is formed, but it displays Error: Transaction has been reverted by the EVM: – Artem Strekalov Jan 10 at 19:56
  • /* my smart contract the ownership of which I want to transfer */ const recipient = new web3.eth.Contract( ABI2, "0xF36198Ce8Dfe6A5694541bb1604195A7b9E2A61D" ); – Artem Strekalov Jan 10 at 20:10
  • /* contract owner */ let signerAddress = gettingOwnerByKey( "private key" ).address; – Artem Strekalov Jan 10 at 20:10
  • /* I want this to be the new owner of my smart contract */ let addressRecipient = "0x82A8AD5c429903c082686a307083330F99c40E53"; – Artem Strekalov Jan 10 at 20:10
  • /* shifting (addressRecipient) using this method, the rights to own the smart contract are transferred */ const data = recipient.methods.shifting(addressRecipient).encodeABI(); – Artem Strekalov Jan 10 at 20:11
