L1SLOAD in Action: Write L2 Dapps that Read from L1 State
In this workshop we will explore some interesting new use cases unlocked by the newly proposed L1SLOAD precompile (RIP-7728). We will develop and deploy L2 dapps that read from L1 state using this precompile.
Interoperability between L2s: Latest developments, Framework and Challenges
The number of L2s is growing rapidly and it’s crucial to create strong interoperability solutions to reduce liquidity fragmentation and friction for users. We provide a framework for analyzing interoperability solutions that defines 6 levels of interoperability. For each level, we deep dive the consequences on UX, DevEx, scalability, fee structures, and MEV potential. We also provide an ecosystem map categorizing the level of interoperability offered by existing projects.
Keynote: Unifying Ethereum Through Intents and ERC-7683
Ethereum has scaled with a diverse ecosystem of L2s—but this created a new challenge: how can this fragmented landscape of potentially millions of rollups feel like a **unified Ethereum**? In this talk, I’ll discuss how intent-based architectures—and new standards like ERC-7683—can help unify Ethereum while maintaining the benefits of Ethereum’s rollup centric architecture.
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.
RIP-7755: Empowering Cross-Chain Interactions
Cross-chain interactions are becoming essential as Ethereum Layer 2 solutions multiply. RIP-7755 changes the game by trustlessly bridging the gap between L2 chains, allowing new use cases that rely solely on Ethereum and its rollups. In this workshop, we’ll explore RIP-7755 by building a cross-chain NFT minting app, focusing on nested storage proof implementation details to eliminate trust assumptions.
Ethereum needs native L2
Right now, L2beat tracks 116 L2s. However, they represent a wide range of trust assumptions, which makes assets—or more abstractly, messages—from these L2s non-fungible and thus significantly hampers interoperability. We are advocating for Ethereum to deploy a large number of native L2s, developed and governed by Ethereum's open-source developers. These L2s would be highly interoperable with L1, fulfilling Ethereum's early promise to provide sharding using L2 technology.
The Three Transitions: Cross-Chain Smart Wallets with Privacy
Last year, Vitalik outlined ["The Three Transitions"](https://vitalik.eth.limo/general/2023/06/09/three_transitions.html) ahead for the Ethereum stack: moving to L2s, smart wallets, and private transactions. The Base team has built [Keyspace](https://docs.key.space/), a cross-chain keystore that helps all wallets makes these transitions. Come learn about how Keyspace works and how Keyspace helps smart wallets sync signers and send private transactions in a multichain world.
Defragmenting Ethereum - Interoperability and the Superchain
With the proliferation of L2s and Dencun (4844), Ethereum has scaled. However, we have a new challenge -- fragmentation. Now we're introducing various interoperability standards across Ethereum and Superchain ecosystem from intents to low latency cross chain bridging primitives. What are these standards and what will enable? How can we create scalable and composable blockspace which enables application developers to onboard the rest of the internet?
Why ERC 7683 is broken and how to fix it
While I appreciate the authors spending time on this problem statement and thinking about standardising flows, ERC 7683 is deeply flawed it still forces offchain agents to understand the order they are trying to fulfill and it doesnt give users any guarantees of execution or understanding of whats happening under the hood, I think its because its standardising things on the "intent" layer where instead we need to standardise more downstream so information like security can be better presented
