The problem KON solves

🤔 Problem

Although blockchain offers benefits like Permissionless and Composability, its real-world use cases are still limited.

• Creators and community managers face high technical barriers and a complex dApp setup process.
• Hard-to-understand ideas like wallets and gas fees make it hard for people to get started.

💡 Solution

KON - "No-code On-chain App Framework"

We aim to create something people can use daily without compromising UX while maintaining the benefits of on-chain.

This project has been under development for some time. By the time this hackathon began, the following features were already in place:

• Reading configuration from ENS Subnames, Text Records
• Basic setup of a PWA (Progressive Web App) based on ENS configuration

In this update, we've added the following new features:

• XMTP group chat integration into app
• Extended functionality via XMTP Agent:
  • Create app (claim ENS Subnames, set ENS TextRecords using XMTP Agent + AgentKit + Smart Wallet)
  • Create ERC-20 for app (using XMTP Agent + Smart Wallet)
  • App owner distributes app coin to users via message (XMTP Agent)
  • App users can request to redeem rewards with coin balance (EAS/NFT)

DEMOs

• A Shop app [Wassie Coffee]: App, ENS config
• A Event app [ETHTOKYO'25]: App, ENS config

👍 Why KON?

• Easy to start: With AI Agent, App owners can start their app in minutes. Users only need a smartphone with a Passkey.
• Ownership: App owners and users fully control their apps and data—Apple or Google cannot remove them. That's why we chose a PWA.
• Composability : Extendable by templates, plugins, smart contracts and reusable on-chain data between apps. Moreover, app and user data are on-chain, and data composability also happens. For example -
  • An event participants get priority access to the following events
  • A shop member receiving discounts at another shop or location
  • Cross-store stamp rally event
• Cost: Reusing templates, plugins, and smart contracts minimizes both initial and running costs.

✨ What's next

• Integration with existing group chats and Farcaster miniapp, enabling a seamless experience from group chat <> KON app
• More templates and feature additions, including voting, theming, crowdfunding, and more protocol integration
• Public version to be released on Mainnet this summer

Challenges I ran into

• XMTP agent design: Initially designed to handle on-chain transactions directly by XMTP agent address, we later discovered, through further review of examples, that users can post messages that trigger those transactions.
• XMTP agent deployment : We had trouble deploying the XMTP Agent to run on a server. We ran XMTP Agent on localhost, which is connected to XMTP production network, but we plan to run it on a server soon.
• Multi-user app ownership: For the case where the app has multiple owners, we explored using a multi-owner or multi-sig account to manage ENS Subnames. (XMTP group chat already has a multi-owner design.) We plan to support it in the future. I'm considering using MultiOwnable functionality of Smart Wallet.
