monad speed-test

Quick examples + webapp to show Monad's throughput

Setup

Build contracts

$ forge build

Setup .env

Create new private key

cast wallet new | grep 'Private key:' | awk '{print $3}'

Populate .env:

PRIVATE_KEY=

Also put the private key in keystore for convenience when using foundry directly

cast wallet import monad-deployer --private-key $(echo $PRIVATE_KEY)

Background

Counter.sol

Counter.sol looks like this:

// SPDX-License-Identifier: UNLICENSED
pragma solidity ^0.8.13;

contract Counter {
    uint256 public number;
    uint256[] public arr;

    function setNumber(uint256 newNumber) public {
        number = newNumber;
    }

    function increment() public {
        number++;
    }

    function incrementMany(uint256 times) public {
        for (uint256 i = 0; i < times; i++) {
            increment();
        }
    }

    function pushMany(uint256 count) public {
        for (uint256 i = 0; i < count; i++) {
            arr.push(i);
        }
    }

    function freeMany(uint256 count) public {
        for (uint256 i = 0; i < count; i++) {
            arr.pop();
        }
    }
}
