When doing division and modulo operation with constant or immutable denominator it is possible to only do compile-time denominator check and skip runtime checks.

Consider following contracts:

pragma solidity 0.8.15;

uint256 constant _MODULE = 17;

contract C1 {
    function f(uint256 a) external pure returns(uint256) {
        return a % _MODULE;
    }
}

contract C2

Issue

Tests are not isolated from each other. I reproduced it using the metacoin box tutorial, adding a new test at the end that checks again the balance. As per the "clean-room" the first account should have all 10000 tokens. It's not.

Using the same command from above:

$ cast tx 0xbedc92801b8a7128898f484006f9e9fb795630f1826f35dd3544db38c07594ab --rpc-url $ARBITRUM_RPC_URL

It is currently not possible to specify the chain ID for a hardhat network invoked with npx hardhat node through any means other than the config file. This means it is impossible to specify the --chain-id argument in the command line, or execute a chain host pragmatically with hre.run('node', { chainId: 100 }).

Please add the chainId parameter to the node command so it is possible to

Description

Change links and references in the docs to run an Ethereum node from parity to openethereum, and change these references in the code too.

Motivation

Currently, docs about running an Ethereum node states that you can use parity-ethereum, but the project is no longer maintained.

There's also lots of comments and b

Describe the enhancement

Every "section" of the video is separated by a clip of what's in ./img/hh-fcc-background.png. We currently have the title text of each section in this repo, but we don't have the timestamp in here!

https://github.com/CarstenNZ/slither-wiki/blob/master/Detector-Documentation.md has a couple of fixes / typos in the detectors description.

We should merge them before the next release

Overview

Currently when I run brownie console, it recompiles all the contracts. Apparently due to some issue which is not identified.

I only want to compile once with brownie compile -all. That's it.
I work on the frontend side, I don't modify the contracts, I just need a local fork and run some scripts.

Currently it's slow as hell

I have some contracts using a library structure data storage, compiled using an older version of Solidity, but which throw an error asking me to make a report here.

In the libraryType.sol contract I have something like this:

library PersonLib {
    struct Data {
        bool   isActive;
        bytes  hashOfData;
        string handle;
    }
    function handle(Data stor
