tx-sitter

At Worldcoin we are looking to build an open-source transaction manager. Our motivation is to save fees compared to existing solutions, to run a high transaction volume while keeping our private keys private, and to contribute a useful project back to the ecosystem. If you are interested in being a potential collaborator or early user, we'd love if you reached out and gave us your feedback or potential feature recommendations. Existing tx-sitter repo Link to tx-sitter Telegram group Feature wish list (descending priority order) Provide an API for sending and managing ethereum transactions across a set of senders The API abstracts away details such as nonce management, transaction resubmission, and gas pricing.

Worldcoin EIP4844 testimonial

Intro to Worldcoin The Worldcoin project started on the premise of giving a token to every human on earth and creating a worldwide UBI project where the value created by AGI gets equitatively distributed to all people across the globe. To achieve that scale in the far future, we are working towards onboarding the first billion people to crypto and solving Sybil resistance. We need scalable infrastructure to make these services accessible for all without compromising on network economic security and decentralization. EIP4844 Motivation More than 750k people have signed up to the Worldcoin Beta App so far – with currently more than 69k weekly active users. Our infrastructure right now is mainly composed of our Privacy-Preserving Proof-of-Personhood Protocol called World Id (currently based on Semaphore) and a non-custodial Ethereum Wallet (more specifically, a Smart Contract Wallet that already sets the stage for future EIPs around account abstraction). EIP4844 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. Currently L2s like Optimism or Starknet post fraud or validity proofs to Ethereum calldata which is limited. As of now transactions with small amounts (<$10) are infeasible, especially in periods of high network demand (more on l2fees.info). After EIP4844 they would submit these proofs to blobspace which provides more storage and a separate fee market thus making fees on L2s a lot cheaper and allowing applications like Worldcoin to benefit from full Ethereum security for all of its users. (Learn more about L2s at L2Beat). In the past, we have built a new sequencer implementation of Hubble (a project originally started by the EF PSE team), which is an payment optimized optimistic rollup using BLS signature aggregation and custom transaction encoding. Although this leads to a massive throughput boost for transfers (<400 gas per transfer), this limits users to simple payments. However, they should be able to access the entire space of web3 applications and buy, sell, send and receive any token.
