## Motivation Solide is a unique platform committed to simplifying smart contract development through its community-driven marketplace, providing developers with a seamless way to discover, customize, and deploy smart contracts. Motivated by the challenges faced in finding and interacting with smart contracts, Solide offers a lightweight IDE where developers can explore a diverse selection of open-source contracts, ranging from token contracts and swaps to advanced concepts like account…

## TLDR Morpheus is a next-generation content provenance scheme for AI-generated content on the web. Designed to overcome the limitations of traditional image watermarking (i.e. digital, latent space, & deep-learning-based), Morpheus can track and identify content even after extreme transformations such as crops, screenshots, and image filters. Morpheus employs a unique approach of perceptual hashing and proof of the transformation to resiliently track content origins across the web. ##…

**Web3GPT** is an Agentic developer tool designed to simplify the process of writing, deploying, and verifying smart contracts across EVM networks—no wallet, IDE, or Solidity expertise required. ### Core Features - 🛠️ Deploy contracts without a wallet or IDE – testnet gas is fully sponsored. - 🔍 Auto-verification of deployed contracts via Blockscout. - 📦 Uploads and pins an IPFS repository with all project source files. - 🌐 Supporting 8 major EVM testnets. - 🧠 Offers a hands-on Solidity…

Adding verifiably deterministic signatures to your existing Ethereum keys will make it possible to have a unique, anonymous identity. Developing this cryptographic primitive, or PLUMEs, into wallets, will unlock sybil-resistant anonymous apps like zk nullifiers for anonymous unlinked airdrops, anonymous decentralized voting which only allows one vote per account, anonymous proof of solvency, and message boards with a consistent identity. We think that fully executing this work will create a…

Scaffold-Eth2 is an open-source toolkit for building decentralized applications on the Ethereum blockchain. It's designed to make it easier for developers to create and deploy smart contracts and build user interfaces that interact with those contracts. It's a new version of scaffold-eth with its core functionality. ⚙️ Built using NextJS, RainbowKit, Hardhat, Foundry, Wagmi, Viem, and Typescript. ✅ Contract Hot Reload: Your frontend auto-adapts to your smart contract as you edit it. 🪝…

Web3.js is an open-source JavaScript/TypeScript library designed to enable developers to interact with EVM-compatible blockchains and develop decentralized applications (DApps). The web3.js library has significant impact on developers working with EVM blockchains, including Optimism network. Web3.js has around 2 million downloads per month on NPM, and 10+ million CDN hits per month. There are, 4500+ library projects depending on web3.js library. As a public good, this open-source library…

**OpenZeppelin Contracts Library** Since the early days of Solidity in 2016, OpenZeppelin Contracts has been the go-to library for smart contract development. Today it is used by everyone from development teams of the largest projects transacting billions of dollars each day to individuals building blockchain applications. The Contracts Library is owned by the OpenZeppelin team, however, the roadmap is highly collaborative and involves a lot of feedback from the Ethereum ecosystem. In…
