Error: cannot estimate gas; transaction may fail or may require manual gas limit #13159

I frequently get errors like the following:

This only happens occasionally (I'll include a testcase below), and it's always hard to fix. The only solution is to set {gasLimit: 3e7} in each contract function call.

One thing that can trigger this problem is when the contract size approaches the maximum possible size. (Hopefully the testcase triggers this as a standalone program -- other contracts in my build environment raise the total size close to the limit.)

Environment

Compiler version: 0.8.14
Target EVM version (as per compiler settings): unknown
Framework/IDE (e.g. Truffle or Remix): Hardhat
EVM execution environment / backend / blockchain client: Hardhat network
Operating system: Linux

Steps to Reproduce

Contracts.sol:

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.14;

contract HasReceiveFunction {
    uint256 public receivedETH;
    receive() external payable {
        receivedETH += msg.value;
    }
}

contract SendFunction {
    function send(address to) external payable {
        (bool success,) = to.call{value: msg.value}("");
        if (!success) {
            revert("Failed to send ETH");
        }
    }
}

index.js:

const { expect } = require("chai");
const { ethers } = require("hardhat");
const SendFunction = require("../artifacts/contracts/Contracts.sol/SendFunction.json");
const HasReceiveFunction = require("../artifacts/contracts/Contracts.sol/HasReceiveFunction.json");

async function deployContract(wallet, contract, constructorArgs) {
    const contractInstance = await ethers.ContractFactory.fromSolidity(contract, wallet).deploy(...constructorArgs);
    await contractInstance.deployed();
    return contractInstance;
}

describe("TestSendReceiveFunction", () => {
  let wallet;

  beforeEach(async () => {
    wallet = await ethers.getSigners();
  });

  it("send ETH", async () => {
    const send = await deployContract(wallet[2], SendFunction, []);
    const hasReceive = await deployContract(wallet[1], HasReceiveFunction, []);
    await send.send(hasReceive.address, {value: 101, gasLimit: 3e7});
    expect(await hasReceive.receivedETH({gasLimit:3e7})).to.equal(101);
  });
)};

To trigger the error, you need to do two things:

Remove the gasLimit: 3e7 args.
Change (bool success,) = to.call{value: msg.value}(""); into (bool success,) = to.call{value: msg.value}("x"); -- this should revert the call, because receive functions require that msg.data.length == 0. It's when this call tries to revert that the "cannot estimate gas" error seems to be triggered.

Hi. Did you fix this error? I have the same shit :/

lukehutch · 2022-06-30T02:05:20Z

I checked the Solidity documentation, and sometimes this is triggered simply by a transaction reverting. I don't know why some transactions reverting trigger this and some don't.

Felix-Monteiro · 2022-07-12T14:05:34Z

Add allowUnlimitedContractSize: true to your hardhat.config.ts under defaultNetworks.networks both "hardhat" and "localhost".
At least it worked for me.

yourchocomate · 2022-09-16T07:09:53Z

Have you fixed it yet? Having the same issue using ether js and walletconnect provider. But works with injected

Am doing: signer.estimateGas.method(parameter)

Edit: My bad, it was my mistake on contract. I was facing the issue for doing unhandled rejections.
The reason was the transaction actually reverting every time for lack of allowance which I didn't handled in contract. Thus, the estimateGas method was reverting every time as the contract call fails.

From my side the solution would be for this by debugging the contract if somehow it reverts the call by any unhandled rejection

Add allowUnlimitedContractSize: true to your hardhat.config.ts under defaultNetworks.networks both "hardhat" and "localhost". At least it worked for me.

but what about in remix ide???

vmmuthu31 · 2022-11-12T16:19:36Z

I had the same issue but solved it myself

I forgot to add the following line of code in my contract

receive() external payable {}

Niceeee, well done man

mirzasetiyono · 2022-12-04T17:16:53Z

in my case, there is a line of code in the constructor that revert the transaction
require(block.timestamp < _poolStartTime, "late");

Check your code for any revert boyz

JoniBrite · 2023-01-02T10:50:27Z

where and how can i run this code please

MMPgenave · 2023-01-05T09:19:31Z

Hi
I got this error in my code.
I just forgot to add "utf8" in fs.readFileSync()

const binary = fs.readFileSync(
    "./SimpleStorage_sol_SimpleStorage.bin",
    "utf8"
  );

and this fixes my error.

And I mean that maybe your code (@lukehutch) has some bugs like that.

Am having same issue. Any idea on how to solve it?
My contract is deployed successfully, all other functions works fine, but when the buy function is called, Metamask will throw an error saying We are unable to estimate gas prize, and it will give outrageous amount for gas fee. It gives me 0.8BNB for gas fee, what could be wrong

Can you share the code of buy function?

kenny1323 · 2023-05-29T20:07:04Z

Same problem.

I solved it in this way.

Create a new directory totally empty: /blabla/createsmartaccount_dir.
Create these 2 files inside it.

/blabla/createsmartaccount_dir/index.js

/blabla/createsmartaccount_dir/package.json

Run the commands

npm install

node ./index.js

#/blabla/createsmartaccount_dir/index.js

const { ethers } = require( 'ethers')
const { EthersAdapter } = require(  '@safe-global/protocol-kit')
const Safe = require(  '@safe-global/protocol-kit')
const { SafeFactory } = require(  '@safe-global/protocol-kit')
const { SafeAccountConfig } = require(  '@safe-global/protocol-kit')
const { ContractNetworksConfig } = require(  '@safe-global/protocol-kit')

const execute = async () => {
    const RPC_URL='https://rpc2.sepolia.org'
    const provider = new ethers.providers.JsonRpcProvider(RPC_URL)
    
    
    
    // Initialize signers
    //metamask wallet and privatekey
    //0x967c1CF5d91f3738c969c76EB4bDddA6da4183c1
    const signerWallet = 
new ethers.Wallet("ca46xxxxxxxxxxxxxxx", provider)

    const ethAdapter = new EthersAdapter({ethers, signerOrProvider: signerWallet})
    
    const chainId = await ethAdapter.getChainId()
    console.log(`ChainId: ${chainId}`)

    
  
    
    const safeVersion = '1.3.0'
    const isL1SafeMasterCopy = false
    const safeFactory = await SafeFactory.create({ ethAdapter: ethAdapter })



    const safeAccountConfig = {
        threshold: 1, // Have to be >= 1 && <= totalOwners
        owners: ["0x967xxxxxxxxxxxxxxxxxxxxxxxxxxxx"],
        eth_estimateGas:30000,
    }
    console.log("Start Deploying Safe");



    
    
	//This Safe is tied to owner 1 because the factory was initialized with an 
	//adapter that had owner 1 as the signer. 
  
    const safeSdkOwner1 = await safeFactory.deploySafe({ safeAccountConfig })

    const safeAddress = safeSdkOwner1.getAddress()

    console.log(`Safe deployed at: ${safeAddress}`)  
}
execute();

johnnyshankman · 2023-05-30T18:45:21Z

My solve was to upgrade everything I could in my project relating to hardhat and ganache.

yarn add ganache
yarn add hardhat
yarn add hardhat-contract-sizer
yarn add hardhat-gas-reporter
yarn add solidity-coverage
yarn add @nomicfoundation/hardhat-ethers

Out of nowhere some conflict between my packages was causing my configuration to no longer function as it used to.

hardhat: {
  throwOnTransactionFailures: true,
  throwOnCallFailures: true,
  allowUnlimitedContractSize: true,
  timeout: 1800000
},

DhaanishTts · 2023-07-31T10:27:18Z

Add allowUnlimitedContractSize: true to your hardhat.config.ts under defaultNetworks.networks both "hardhat" and "localhost". At least it worked for me.

Sometimes its working and sometimes not

Hi everyone! This issue has been automatically closed due to inactivity.
If you think this issue is still relevant in the latest Solidity version and you have something to contribute, feel free to reopen.
However, unless the issue is a concrete proposal that can be implemented, we recommend starting a language discussion on the forum instead.

rodonguyen · 2023-11-26T03:50:55Z

Have you tried specifically setting a higher gas limit?

        // if you are using ethers.js
        ....
        const contractFactory = new ethers.ContractFactory(abi, binary, wallet);
	const overrides = {
		gasPrice: 10000000000, // Can set this >= to the number read from Ganache window
		gasLimit: 6721975, // Use the same gasLimit as read from Ganache window (or a bit higher if still having issue)
	};
	const contract = await contractFactory.deploy(overrides);

Let me know if that helps!
