L1SLOAD Precompile: Read L1 State from your L2 Contract
We recently introduced [RIP 7728: L1SLOAD Precompile](https://github.com/ethereum/RIPs/pull/27). This is a new L2 precompile that allows dapps on L2s to read from the L1 state. In this talk, we will explain how L1SLOAD works, and we will highlight some of the most exciting use cases that this precompile will unlock.
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.
L2 EVM Common Core: A Path Beyond EVM Equivalence
Network effects of the EVM have locked many of the L2s into equivalence with the L1 EVM. L1 is optimized for moderate throughput and maximal decentralization, but L2s need higher throughput and can rely on heavier full nodes. The talk will present a vision for an L2 EVM Common Core as a new base VM for participating L2s. It aims to offer a way to ship more ambitious EVM changes without increasing L2 fragmentation. It is a result of our work as leads of the RollCall L2 coordination process.
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.
A Revenue Model for Based Rollups
We outline the costs that a based rollup has, followed by the paths it has to revenue generation, revenue capture and finally revenue redistribution. We demonstrate that based rollup costs are front-loaded and non-negligible. Based rollups must pay for ZK-provers, app- and user-onboarding, R&D, etc, as well as L1 fees. We consider several continuous and once-off revenue models, and compare the pros and cons of each according to several key properties that based rollups are expected to have.
Keynote: The REAL state of L2s
The evolution of Layer 2 solutions has been pivotal in scaling blockchain technologies. This talk, led by L2BEAT founder Bartek Kiepuszewski, delves into the current landscape, recent advancements, and future potential of L2 ecosystems. It will try to address some myths and current challenges of the space. Some important changes to L2BEAT risk framework will also be announced.
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?
