Unpacking Intents with Hyperlane's Eda Akturk 40:40

26 days ago40:40

40:40

In this episode of Composable, hosts Alysia and Ellie speak with Eda Akturk , a developer advocate at Hyperlane , about intents in general and the recently released Open Intents Framework, specifically. They explore what intents are, how they're changing user experiences in web3, and dive into the collaborative effort behind the Open Intents Framework, which aims to make it easier for developers to build intent-based applications. Key Topics Covered How to define intents in a blockchain context (eg, allowing users to specify their goal rather than know how to reach it themselves) The Open Intents Framework, a collaborative effort led by Hyperlane, Bootnode, and the Ethereum Foundation How the framework builds upon the ERC-7683 standard proposed by Across and Uniswap The framework's three main components: smart contract base, open-source solver implementation, and ready-to-use UI The mechanics of intent transactions and how solvers fulfill user requests How solvers front liquidity and manage finality risks when bridging between chains Target audiences for the Open Intents Framework, especially new chains and crosschain applications Benefits of standardization for creating composability between different intent systems The competitive solver market and how it leads to better UX The future vision for intents in the blockchain ecosystem The unusual level of cooperation between competing L2s and infrastructure projects Composable is a bi-weekly podcast exploring crypto's building blocks.

Join hosts Ellie and Alysia as they discuss the realities of cross-chain bridges, including looking at which are the most used, crypto UX, security tradeoffs, etc. — and then put several bridges to the test in a live demo, bridging assets across Ethereum, Arbitrum, and Base. Key topics covered include: Speed and fee comparisons across different bridge types Bridge architectures: canonical, intent-based, and externally verified Security tradeoffs between bridge designs Emerging trends: intent standardization and ZK bridges Current state of bridging UX and areas for improvement The live demo segment didn't make for great audio content, but you if you'd like to watch them test drive these bridges, you can find the video on Composable's YouTube channel at youtube.com/@composablepod. Essential listening for anyone looking to understand blockchain interoperability and cross-chain asset transfers. Composable is a bi-weekly podcast exploring crypto's building blocks.

Composability Unpacked: Synchronous vs. Asynchronous and Why It Matters 22:49

20 weeks ago22:49

22:49

In the debut episode of Composable , hosts Alysia and Ellie begin with a foundational discussion about composability and its role in shaping Ethereum’s future. In it, they break down: The difference between synchronous (transactions completed within one block) and asynchronous composability (transactions completed across multiple blocks). UX pain points caused by fragmentation, like "dust" left on chains after cross-chain transactions. The value of synchronous composability for creating seamless user experiences and enabling new financial products like flash loans. The challenges of achieving synchronous composability across different chains, and the need for coordination and trustless confirmation layers. Composability in terms of ACID properties (atomicity, isolation, consistency, durability) Trade-offs between synchronous and asynchronous systems, including infrastructure complexity and trust assumptions. Plus, they explore current solutions like bridges, intent-based bridging, and message-passing while discussing what’s needed to make Ethereum composable again.
