Kroyii is an AI-powered onchain agent that acts on your behalf. Grant permissions once, and Kroyii reasons with Venice AI and executes onchain actions autonomously via MetaMask Smart Accounts
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
Your EOA wallet is upgraded to a MetaMask Smart Account using EIP-7702
You grant Kroyii scoped permissions via ERC-7715 Advanced Permissions
Venice AI powers the agent's reasoning — deciding what onchain action to take
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.
