Reagent_AI

The Problem: AI agents cannot truly act autonomously if they get blocked by wallet popups every time they need to execute a transaction or pay for a service. However, giving an AI a private key with unlimited funds is a massive security risk.

The Solution: Reagent AI bridges the gap between autonomy and security. By leveraging the MetaMask Smart Accounts Kit, users can deploy a Smart Account Vault on Base Sepolia. Instead of signing every transaction, the user signs a single off-chain EIP-712 delegation granting the AI agent a strict budget (e.g., $5.00 USDC) enforced by cryptographic caveats.

The AI agent (powered by Llama 3.3) can then autonomously plan its tasks, verify its budget, and pay for services (like bioinformatics API calls) on-chain. All transactions are relayed gaslessly via the 1Shot Permissionless Relayer using the ERC-7710 delegation standard, providing verifiable proof of agentic activity on the Base network.

During the hackathon, I built this entire architecture from scratch:

• Smart Accounts: Integrated MetaMask SAK to deterministically deploy ERC-4337 smart accounts on Base Sepolia.

• Programmable Auth: Implemented off-chain delegation signing using ERC20TransferAmountEnforcer caveats to hard-cap agent spending.

• ERC-7710 Settlement: Integrated the 1Shot API as a permissionless relayer to execute redeemDelegation transactions gaslessly on-chain.

• A2A Coordination: Built a secure sub-delegation system where the main agent spawns temporary session keys for specific API calls, rather than passing the master agent key.

• AI Integration: Connected Groq/Llama 3.3 to act as the "brain," capable of multi-step planning, cost estimation, and executing HTTP requests with x402 payment headers.
