Kroyii

The Problem Managing onchain actions today is exhausting. Every transaction needs manual approval, gas management is a chore, and AI agents can't act independently without constant human intervention.

What Kroyii Does Kroyii is an autonomous onchain agent that works for you. Connect your wallet, upgrade it to a MetaMask Smart Account, grant Kroyii a set of permissions once via ERC-7715 — and your agent handles the rest.

How It Works

1. Your EOA wallet is upgraded to a MetaMask Smart Account using EIP-7702

2. You grant Kroyii scoped permissions via ERC-7715 Advanced Permissions

3. Venice AI powers the agent's reasoning — deciding what onchain action to take

4. Kroyii executes permitted transactions autonomously on your behalf, no further approvals needed

Why It Matters Kroyii demonstrates the future of wallet UX — where AI agents are first-class onchain actors, not just chatbots. Permissions are scoped, revocable, and transparent.

Kroyii is an AI-powered autonomous onchain agent built on MetaMask Smart Accounts Kit and Venice AI. During this hackathon, we designed and implemented the full end-to-end flow from scratch — starting with project scaffolding using Scaffold-ETH 2 with the official MetaMask ERC-7715 extension, through wallet integration, smart account upgrading via EIP-7702, and ERC-7715 Advanced Permissions granting. We built a Venice AI-powered natural language agent that reasons about user instructions and executes onchain transactions autonomously through the user's MetaMask Smart Account. We also implemented a persistent transaction history, a clean sidebar-driven UX, and deployed the full application to Vercel on Sepolia testnet. The entire project was built within the hackathon window with no prior codebase.
