Hardlydifficult-eth NPM

HardlyDifficult Ethereum Contracts

A collection of reusable contracts and Javascript helpers for Ethereum.

Usage:

npm i hardlydifficult-eth

Javascript Helpers

These helpers which will deploy contracts for testing using the exact bytecode and configuration as they have on mainnet, with the exception that you are the owner to enable privileged actions such as mint.

You can deploy these to Ganache or any network for testing. The scripts simply use your current web3 configuration.

Using these will give you an accurate representation of gas costs, error conditions, and any oddities to their specific implementation.

Tokens

SAI: ERC-20 with 18 decimals and a mint function
USDC: an upgradable ERC-20 with 6 decimals and mint and blacklist functions

Usage example:

const { tokens } = require("hardlydifficult-eth");
const from = accounts[0];

// Deploy a SAI contract for testing
const sai = await tokens.sai.deploy(web3, from);

// Mint tokens
await sai.mint(accounts[1], 100, { from });
