L2BEAT is an Ethereum Layer Two (L2) scaling analysis and research website. We compare Ethereum L2s by monitoring their usage & TVL-related metrics, verifying their documentation against the source code, and manually assessing associated risks. We have created a risk framework for L2s and bridges, along with open-source monitoring tools that check for changes in their smart contracts' parameters.

Geth (go-ethereum) is a Go implementation of Ethereum - a gateway into the decentralized web. Geth has been a core part of Ethereum since the very beginning. Geth was one of the original Ethereum implementations making it the most battle-hardened and tested client.

ETHGlobal is the largest developer focused community in Ethereum. Most known for their hackathons, ETHGlobal has run 50+ hackathons around the world and online. To support builders at any point in their journey, ETHGlobal builds products for its developer community's success including: Hackathon (online/in-person), Guides (self-directed education), Summits (online/in-person), Jobs, and more.

A curated group of Ethereum builders creating products, prototypes, and tutorials to enrich the web3 ecosystem. We mentor developers and orgs through the SpeedRun and beyond.

Solidity is a statically-typed curly-braces programming language designed for developing smart contracts that run on Ethereum.

Ethers is a complete and compact library for Ethereum and related chains, providing all functionality required for dapps, wallets and any other utilities and scripts. It is widely used throughout the community and is a dependency for a large portion of the ecosystem with over 4 million npm downloads monthly.

The 0xPARC Foundation promotes application-level innovation on Ethereum. Our primary areas of focus are: - Cryptography: ZK, MPC, and more. - Autonomous Worlds: funding projects like Lattice, Dark Forest, DFDAO, etc - Education: we organize learning residencies, hackathons, and conferences on ZK and AW. 0xPARC funds infrastructure work, research, and groups that would otherwise be underfunded.

This nomination is for a collection of contributors to EIP4844. EIP-4844 introduces a new kind of transaction type to Ethereum which accepts 'blobs' of data to be persisted in the beacon node for a short period of time. These changes are forwards compatible with Ethereum's scaling roadmap, and blobs are small enough to keep disk use manageable. EIP-4844 is project-neutral and being developed 100% in the open by a wide mix of developers across different teams, this collection aims to reward that network of contributors.

This collection consists of 100 open source software projects that are essential dependencies of the Optimism tech stack. This software is critical to the success of the OP Stack.

Lattice is facilitating complex on-chain projects with MUD (https://mud.dev): an application framework for Ethereum & Autonomous Worlds (https://shortest.link/autonomous) MUD helps developers be more ambitious on-chain: using the OP Stack and MUD, we built OPCraft — an on-chain Voxel Game (https://shortest.link/opcraft) — and we enabled dozens of team to push the envelope of Dapps. see below:

OpenZeppelin provides security products to build, automate, and operate decentralized applications. We also protect leading organizations by performing security audits on their systems and products.

DefiLlama is an OpenSource project that tracks metrics for DeFi protocols (TVL, volume, fees, revenue, treasury...) transparently, making our data available for free to everybody. On top of that we've built: - LlamaPay, a payments tool used by multiple optimism protocols such as Velodrome - LlamaSwap, a dex meta-aggregator - our free price & metrics API and we maintain ChainList.

Lighthouse is an Ethereum consensus client that connects to other Ethereum consensus clients to form a resilient and decentralized proof-of-stake blockchain. It is one if the most used Ethereum consensus clients, focused on performance and security. It is free and open source with the most permissive license we could find (Apache 2.0).

wagmi is a collection of React Hooks containing everything you need to start working with Ethereum. It’s used at organizations like ENS, Sushi, LooksRare, WalletConnect, Stripe Crypto, and Gitcoin. wagmi makes it easy to "Connect Wallet," display ENS and balance information, sign messages, interact with contracts, and much more — all with caching, request deduplication, and persistence.

The Remix Project is a rich toolset including Remix IDE, a comprehensive smart contract development tool available for web and desktop. Remix Plugin Engine and Remix Libraries are low-level tools for wider use. Remix IDE can be used for the entire journey of contract development by users of any knowledge level and as a learning lab for teaching and experimenting with Ethereum.

For the past 5 years Gitcoin has been focused on building and funding digital public goods. By popularizing these concepts, it's helped spark a trend across the industry of giving back and supporting Ethereum developers. Through its implementation of quadratic funding specifically, it's helped fund projects like ethers.js, Hardhat, POAP, Prysm, and even Optimism itself.
