Hey guys

I have an issue with truffle. So truffle is supposed to compile modified contracts only right (after first compile). Mine is compiling all contracts everytime, which is kinda annoying. Any idea how to solve this?

hi >< Does anyone know how to debug "Fail - Unable to verify" when using truffle-verify plugin? Thanks! Most of my contracts were successfully verified while 3 of them failed. I tried --debug but still no cue. Thanks very much!

Hello everyone! I'm following along with the truffle tutorial and after a few tweeks got everything working great! However, now I'm struggling to add a returnPet() function to my solidity smart contract. The transaction fails and somehow metamask knows this ahead of time because it warns me that it might fail before confirming ("let's try anyway"). I've posted on stackoverflow, but responses have been slow. I feel like I'm missing something fundamental and could really use some help figuring out where to look first.

Hello

can anyone help me ?
i trying to do deploy some contracts to truffle test network but i got many errors

Error: Contract error: contract binary not set. Can't deploy new instance.
This contract may be abstract, not implement an abstract parent's methods completely
or not invoke an inherited contract's constructor correctly

Hey guys, is there a way to "re-fork" a chain on ganache. I want to start a ganache server, but as new contracts get updated, the forked Blockchain is outdated. My goal is to re-fork every minute or so, so ganache is only 1 minute behind the live mainnet at all times. Anyone know how I can do this?

Hello. I'm using latest ganache 7 programmatically with ethers. I'm trying to figure out how to mine instantaneously using a fork. I have tried 3 different providers to fork from. I'm trying to do a uniswap trade. It still seems to take no less than 9 seconds to complete. Any suggestions on what to try or is this not possible? Thanks

@lwillmeth

Hi all, new to truffle (v5.4.30) and when I run a test that initializes my contract, it fails with: "intrinsic gas too low".

It compiles fine, but I tried reducing my contract's constructor to only calling the ERC777 constructor, and still get this error.
I tried increasing truffle-config's networks.live.gas and gasPrice, but nothing changed.

The only google results are from a couple years ago, using older versions of truffle. I can run other tests, and this contract's constructor looks simple, so I'm not sure what's wrong here. Any ideas?

Levi W.

@lwillmeth

I'm still having trouble finding my problem, but using a fresh truffle init, I boiled it down to extending a contract from @openzeppelin/contracts
Here's a gist of my boiled-down contract and migration, any tips are much appreciated:
https://gist.github.com/lwillmeth/8050be839f6baa3e31dbc16500b63d1c

The error goes away if I copy the parent contract out of the library and into contracts/, so maybe this is a syntax mistake on my part? I'm not seeing it, and the contract compiles, but won't initialize.

Levi W.

@lwillmeth

It seems this only happens with @openzeppelin's ERC777 contract. I'm able to extend several of their other contracts without problem.

When writing tests using solidity, how do I access the addresses of the accounts that are setup automatically in ganache? In javascript, they are passed as an array to the test, is there something equivalent I can do in solidity?

I was able to mitigate this issue by doing a combination of OS updates, XCode Command line tool updates, updating npm config set python to python3 after updating python using brew.

Hello all,

Trying to get a basic set up running and I was following along setting up Truffle on Avalanche with these docs:

https://docs.avax.network/build/tutorials/smart-contracts/using-truffle-with-the-avalanche-c-chain/

But when I try to open the console, I get this error:

Error: ProviderSubprovider - specified provider does not have a sendAsync method

I feel like there is something just out of date in the docs, but I'm having a hard time nailing down exactly what's going wrong here.. Anyone able to point me in the right direction?

Hello, does anyone know the proper way to import ABI jsons? This minimal example doesn't appear to work:

pragma solidity >=0.8.0 < 0.9.0;

import '@uniswap/v2-periphery/build/IUniswapV2Router02.json' as IUniswapV2Router02;

contract Minimal {

  IUniswapV2Router02 immutable uniRouter;

  constructor(address _uniRouter) public {
    uniRouter = IUniswapV2Router02(_uniRouter);
  }
}

It fails with the following error. It should recognise that IUniswapV2Router02 is a contract right?

Compiling your contracts...
