Privacy-preserving Paymaster - Kiwi News: https://news.kiwistand.com/stories/Privacy-preserving-Paymaster?index=0x64626a162028b3af373c901a4d18ad2ebf9ecdb5c709cf6906fd9a608d9607531a459a32 - Source: https://ethglobal.com/showcase/privacy-preserving-paymaster-hap9s - Shared 15 May 2023, 6 upvotes, 0 comments This is a project write-up for a privacy-preserving paymaster that lets users withdraw from mixers such as Tornado Cash into a fresh address without holding ETH for gas. Users generate a zero-knowledge proof of the withdrawal and encode it in the paymaster data, and the paymaster validates the proof, executes the withdrawal, pays the gas fee, and deploys a new smart account to receive the funds. The build uses the ERC4337 standard, contracts inherited from eth-infinitism with overridden validation logic, a modified trampoline browser extension to create the UserOp, and open-source Tornado Cash code for deposits and proof generation. The contracts have been deployed to Goerli, Polygon Mumbai, Optimism Goerli, Gnosis Chain, Linea, Mantle testnet and Scroll testnet. ## 2. EVM Actions | ETHGlobal - Kiwi News: https://news.kiwistand.com/stories/EVM-Actions-or-ETHGlobal?index=0x66953e6ea41faa9acb05581f1629c76055ced01264388c67821fe02f3b24a1512b8c1172 - Source: https://ethglobal.com/showcase/evm-actions-2gdki - Shared 15 July 2024, 5 upvotes, 1 comment EVM Actions is a standard for APIs that return signing requests, such as messages or transactions, directly to a user through publicly accessible URLs, with each action following a predefined JSON specification. Actions come in four types: transaction, signature, link, and 1-click login, the last of which can use providers such as Dynamic or Privy. The project includes a standard with documentation built with Vocs, a Chrome extension built with Plasmo that detects actions on pages such as Twitter and Discord, and Next.js starter kits. The extension connects to wallets via WalletConnect through Dynamic, because injected providers such as Metamask were difficult to interact with. ## 3. Farcaster feed-take-over rights - Kiwi News: https://news.kiwistand.com/stories/Farcaster-feed-take-over-rights?index=0x6600a638b71051000e8c7f5eff4eaf962c9f0c7f87c207c1fe727246116b7da35adc12c9 - Source: https://ethglobal.com/showcase/lemon-juice-coihq - Shared 24 March 2024, 4 upvotes, 5 comments LEMON JUICE is a hackathon project that creates a market around the right to take over another user's Farcaster feed, so one user can submit a message through another user's account. The project says this could support advertising mechanics not possible on centralised social media and grow into a decentralised advertising ecosystem. It is built with Frog frameworks as a series of Frame pages. Users first check for an "FTR" token, a Zora 1155 on Base, using Airstack middleware for an allowlist, and holders submit cast text that is posted via the Neynar API to the LEMON JUICE Farcaster client. ## 4.

Farcaster AI Content Cop made at ETHOnline Hackathon - Kiwi News: https://news.kiwistand.com/stories/Farcaster-AI-Content-Cop-made-at-ETHOnline-Hackathon?index=0x66fa54de88b81b3536ca3ea4926a3464f2d885ea5c477850760dd60e9d0658a231f044a0 - Source: https://ethglobal.com/showcase/ai-content-cop-fwqq8 - Shared 30 September 2024, 2 upvotes, 0 comments Farcaster Content Cop is a hackathon project built for the EthGlobal 2024 hackathon that uses Galadriel's L1 blockchain for decentralized AI to detect spam and assess ethics in Farcaster user content. The application retrieves a user's follower count, following count, FarScore and recent casts through the Airstack API, then generates spam likelihood, ethical assessment and action recommendations such as monitoring, warning or reporting. The article says the team built the front end in React.js with TypeScript and deployed its AI models as Solidity smart contracts on Galadriel's L1. It also lists future plans, including support for Lens Protocol and XMTP frames.
