Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@nahmii/sdk

The @nahmii/sdk package provides a set of tools for interacting with Nahmii 3.

Installation

npm install @nahmii/sdk

Using the SDK

CrossChainMessenger

The CrossChainMessenger class simplifies the process of moving assets and data between Ethereum and Optimism. You can use this class to, for example, initiate a bridge operation of ERC20 tokens from Nahmii back to the base layer, accurately track when the bridge operation is ready to be finalized on base layer, and execute the finalization transaction after the challenge period has elapsed. The CrossChainMessenger can handle bridge operations in either direction of ETH and any ERC20 or ERC721 compatible token.

The CrossChainMessenger automatically connects to all relevant contracts so complex configuration is not necessary.

L2Provider and related utilities

The Nahmii SDK includes various utilities for handling Nahmii's transaction fee model. For instance, estimateTotalGasCost will estimate the total cost (in wei) to send at transaction on Nahmii including both the L2 execution cost and the L1 data cost. You can also use the asL2Provider function to wrap an ethers Provider object into an L2Provider which will have all of these helper functions attached.
