Stable Summit · Jul 11, 2024

Kenote by Valora This video features Laura Suttie from the Valora product team discussing the challenges of user experience (UX) in the crypto space, particularly for new users. She highlights the complexity of interacting with decentralized apps (dApps) on mobile devices, noting that although a significant portion of dApp traffic comes from mobile users, very few dApps offer a mobile app. Laura emphasizes Valora's commitment to simplifying the UX by focusing on mobile solutions and showcases a feature that allows users to easily earn on stablecoins within their app. She encourages developers to utilize Valora's mobile stack for creating better UX and invites viewers to connect with the team for further collaboration in improving Web3 experiences.

Conflux - Web3 UX Unconference · Nov 16, 2023

No description The video features a speaker named Emhaz discussing the mobile user experience (UX) for Ephium, a blockchain technology. Emhaz highlights three main points: the current state of Ephium on mobile, which involves a cumbersome process of switching between apps and wallets; the importance of integrating nodes and light clients into mobile experiences for better decentralization and ease of use; and a thought experiment on replacing outdated technologies like phone numbers with Ephium addresses to enhance security and user control. Emhaz also touches on the potential for native operating system support for Ephium to improve UX. The talk is concluded with an invitation for questions and the announcement of the next speaker from MetaMask.

Gregory Markou

Conflux - Web3 UX Unconference · Nov 16, 2023

No description The video features Greg, a co-founder and CPO at Chain Save, discussing the concept of removing network switching in the blockchain space to create a seamless user experience. He emphasizes that developers should not be asking which blockchain to build on, but rather how they can enable users to access everything from a single chain. Greg presents a solution developed during a hackathon that aggregates assets across chains, allowing users to perform transactions without worrying about which chain they are on. This approach uses bridges for transactions and aims to reduce costs and improve user experience. Greg also covers the importance of app developers not having to worry about where their players are located and users not needing to learn new chains. He provides an example with a demo game that utilizes wager matches across different chains without requiring users to switch networks or fragment their funds. The talk further explores the use of session keys and embedded wallets within games to allow transactions on multiple chains without network switching. Greg suggests that multi-chain accessibility could attract a larger user base for apps, making them more inclusive. Lastly, he touches on future developments in multi-chain interactions, including the use of relayers for optimistic transfers and higher-level bridge abstraction protocols that could significantly advance this area. The video concludes with a brief Q&A discussing the challenges of multi-chain UX and potential solutions

No description In this video, Jan, who has a background in cultural anthropology and cognitive science, discusses the intersection of human uniqueness and sameness in the context of user experience (UX) design. He explores how understanding both the individuality and the common cognitive processes of people can be used to create persuasive UX designs that can either enhance user experience or exploit users. Jan emphasizes the ethical considerations in product design, urging designers and developers to avoid deceptive practices. He also provides examples of both positive and negative UX practices in well-known companies and shares resources for designers to learn about using cognitive biases ethically to improve product design.

Conflux - Web3 UX Unconference · Nov 16, 2023

No description The video discusses various perspectives on cryptocurrency adoption, primarily focusing on improving user experience and reducing friction for users. It starts with a description of Kiwi News, a platform like Hacker News or Reddit for Web 3, emphasizing the importance of simplifying interactions with wallets and transactions to facilitate adoption. The conversation then shifts to the potential of B2B transactions in blockchain, highlighting how blockchain as a ledger technology can be particularly useful for trustless ecosystems and micro-businesses in need of credit. One speaker, Kyle, brings up the necessity of concentrating on adoption to achieve network effects similar to major social platforms like LinkedIn and Facebook. This is contrasted with the idea that usefulness should be prioritized over adoption. There is also a discussion about whether financial use cases are sufficient for Web 3 adoption or if more focus should be placed on solving real-world problems. The dialogue also touches upon the challenges in emerging markets like Turkey and Argentina, where crypto is used as a hedge against inflation and financial instability. The speakers explore how crypto can provide solutions for people in economies with limited access to traditional financial services. Lastly, there is an emphasis on the responsibility of those involved in crypto to consider global inclusivity and ensure that underprivileged regions are not left behind. The speakers suggest that building robust applications suitable

What if I told you every account you created on every website you’ve visited in your life might have some money just sitting in it? In Web3, “create a wallet” is the new “create an account.” I’ve done a deep dive into wallets and found design trends that are going to confuse non-Web3-fluent people so much that many will simply abandon them, often before using them even once. And these go far beyond the “store your passphrase on a piece of metal in a fireproof box.” Want to make your wallet work better for new (and current) users? I’ll show you the biggest and most common wallet UX problems and suggest basic changes you can start implementing tomorrow. https://twitter.com/tamaraadlin Tamara Adlin Advisor & Product Coach Blockchange Ventures Join us for an insightful talk by Tamara Adlin, a seasoned professional in the tech industry.
