Start Date: 2024-03-08

Scope of mitigation measures to review:

PR 13 - Adding vulnerabilities doc for lockbox2 specified by the Cantina audit findings.
PR 14 - Addressing sandwich attack fix in the deposit() function
PR 15 - Addressing small Cantina audit findings

Vim has a Terminal Mode!

Since v8.1 (May 2018), Vim has shipped with a built-in terminal. See https://vimhelp.org/terminal.txt.html or type :help terminal for more info.

Why use this? Mainly because it saves you jumping to a separate terminal window. You can also use Vim commands to manipulate a shell session and easily transfer clipboard content between the terminal and files you're working on.

Key Bindings

Setting Up WSL

Install A Distro:

Run the following in powershell as admin Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux
Install a distro (ex: Ubuntu 18.04 LTS - https://www.microsoft.com/store/apps/9N9TNGVNDL3Q)
Open your distro you installed via the start menu, let it setup
Update and upgrade

sudo apt-get update

	// To enable meta transaction, let create a generic method that calls executeMetaTransaction by taking the user signature
	// and then execute transaction via Biconomy

	// Dependencies
	import {toBuffer} from "ethereumjs-util";
	import abi from "ethereumjs-abi";
	import events from "events";

	// Initialization of web3
	let web3 = new Web3(window.ethereum);

	* The following is an implementation of the finite field GF(2^8) as bit vectors of length 8, where the nth bit represents the
	* coefficient of the nth power of the generator in each element, and the generator satisfies the minimal polynomial
	* x^8 + x^4 + x ^3 + x^2 + 1 in the prime field Z_2, in which addition is equivalent to XOR and multiplication to AND.
	* The elements of GF(2^8) thus represent polynomials of degree < 8 in the generator x. Addition in this field is simply
	* bitwise XOR, but multiplication requires the elimination of powers of x <= 8.
