Build & Brew: Intro to the Open Intents Framework - Eda Akturk (Hyperlane)

In this workshop, Eda Akturk from Hyperlane provides an introduction to the Open Intents Framework (OIF), a collaborative initiative that aims to simplify cross-chain interactions in the Ethereum ecosystem. Eda explains how intents can help solve Ethereum's fragmentation problem by providing users with a more seamless experience when transferring assets across chains.

Eda led this workshop on March 13, 2025, as part of Espresso's $100K Build & Brew Hackathon. Hackers have until March 31 to register and submit their projects. Register here: https://tinyurl.com/build-n-brew

Key Points Covered:
The evolution of Ethereum from a single chain to a fragmented multi-chain ecosystem following the rollup-centric roadmap
How the current fragmentation creates friction for users who need to navigate multiple networks
The concept of intents as a declarative model where users specify what they want rather than how to execute each step
How solvers (specialized off-chain actors) handle the complexity of cross-chain transactions on behalf of users
The challenges developers face when building intent-based applications, including the need for partnerships or custom infrastructure
The Open Intents Framework as a solution providing modular, open-source components for building intent-based applications
The three key components of OIF: composable smart contracts, an open-source solver implementation, and customizable UI templates
How OIF builds upon existing standards like ERC-7683 while providing practical implementation tools
