Overview

SpendGuard AI is an intelligent safety and spending control layer designed for autonomous AI Agents on NEAR. As AI agents begin managing transactions and interacting with Web3, risks like unauthorized overspending or rule violations emerge. SpendGuard AI acts as a secure middleware: it intercepts AI-proposed actions, evaluates them against custom safety rules and daily spending limits, and requires user approval before submitting secure transactions to the NEAR blockchain using near-api-js.

Key features:

Safety Rule Engine: Automatically blocks proposals matching scam patterns or violating rules
Spending Limits: Daily (10 NEAR) and per-transaction (3 NEAR) limits with progress tracking
AI Agent Simulator: Simulates AI agents proposing financial actions
NEAR Testnet Integration: Signs and sends real transactions upon user approval
Dashboard UI: Modern Tailwind CSS interface with real-time updates, dark/light mode, Chart.js statistics, and CSV export
Audit Logging: Complete activity history stored in SQLite

Built solo for NEAR Hackathon 2026. Tech stack: Node.js, Express, SQLite, Tailwind CSS, near-api-js.
