Description

# Vortex Agentic Pay

## What is Vortex Agentic Pay?

A decentralized infrastructure that enables AI agents to execute onchain transactions autonomously using MetaMask Smart Accounts, x402 micro-payments, Venice AI, and 1Shot API.

## Key Features

### 1. Smart Account Powered Agents

- EIP-7702 Smart Account upgrade from EOA

- ERC-7715 Advanced Permissions for agent budgets

- Stateless7702 implementation for gas efficiency

### 2. x402 Micro-payments

- Pay $0.01 per agent request

- ERC-7710 delegation for automated payments

- Venice AI integration for intelligent responses

### 3. A2A Coordination

- Delegation chains for agent-to-agent permissions

- Redelegation with caveats (time limits, call limits)

- Open delegation for permissionless agent interactions

### 4. 1Shot API Integration

- Gas abstraction with USDC payments

- Permissionless relayer for EIP-7710 transactions

- No signup, no pre-funding required

## Tech Stack

- Frontend: Next.js 16, React 19, TypeScript

- Smart Accounts: MetaMask Smart Accounts Kit v1.6.0

- AI: Venice AI (llama-3.3-70b)

- Payments: x402 Protocol, ERC-7710/ERC-7715

- Gas Abstraction: 1Shot Permissionless Relayer

- Blockchain: Base Sepolia (EIP-7702 enabled)

## What We Built

1. Agent can request budget (10 USDC/week) via ERC-7715

2. Agent pays $0.01 via x402 to access Venice AI

3. Agent sends user operations via bundler (Pimlico)

4. A2A delegation for multi-agent coordination

5. 1Shot relayer for gas sponsorship in USDC
