dm3 - Decentralized, Secure and Open Messaging Protocol
dm3 is a protocol enabling decentralized, open, and secure messaging based on established web3 services like ENS and IPFS. It doesn't rely on any central service. The user has complete control over where their messaging data is stored. By using ENS names and ENS text records as the registry for public keys, the user owns the identity linked to their messages. dm3 comes with a reference implementation for a standalone web application, a widget, and a delivery service.
PIET
Piet is a web application providing support to understand smart contract architectures. This is approached by generating a graphical representation of such architectures and a possibility to query deployed instances of smart contracts. The graphical representation shows the inheritance structure of solidity contracts. In addition to the inheritance structure the defined enumerations and structs are shown. To provide understanding of one single solidity contract Piet offers an inspector view showing all members of the contract including the inherited ones. The presentation of the contract and the contract members is enriched by documentation labels derived from Ethereum NatSpec tags. Piet also provides an interactive mode enabling to read the state of a smart contract, sending transactions and browsing through events. This is achieved by connecting to deployed smart contracts through an injected web3 object.
Farcaster frames: building embeddable Ethereum apps
Frames are an open standard for creating embeddable, interactive apps in social media feeds and on the web. They help solve one of the hardest problems for Ethereum dapp developers: distribution. Although frames originated on Farcaster, it's now possible to build cross-platform frames that work on Farcaster, Lens, XMTP, and the open web. In this hands on workshop we'll introduce the core concepts behind frames and build a simple frame app that interacts with a smart contract.
Keynote: Nomic Foundation’s vision for Ethereum’s tooling ecosystem
Nomic Foundation is the nonprofit behind Hardhat. Nomic’s co-founder and CTO will walk you through Nomic’s long-term vision for a community-driven developer tooling ecosystem for Ethereum.

Digital Identity
Christian Lundkvist of ConsenSys (https://consensys.net/) presents on digital identity.
Introduction to Snarks
Blockchains are a hostile world were all information is public and computations are expensive. A technology called zkSNARKs is coming to the rescue: It allows both a tremendous speedup in verifying the correctness of a computation while at the same time it hides the private details from prying eyes. This talk tries to give an idea about how and why it works.
Missing Links in the Ethereum Stack
Observations about what developer tools missing from the Ethereum stack, yet currently available to traditional web developers.
