Description
SoloFi CFO is a backend-only AI agent registered on OKX.AI as Agent Service Provider #6130. It acts as an automatic Chief Financial Officer for Web3 freelancers, remote workers paid in stablecoins, and crypto solopreneurs — people who currently track invoices and payments manually across wallets and spreadsheets.
Three core pillars:
1. Smart Invoicing & Auto-Tracking — create invoices via chat, agent watches X Layer for the matching on-chain payment.
2. Autonomous Budgeting (Pockets System) — define percentage-based allocation rules (e.g. 70% Operational / 30% Savings); the moment a payment lands, funds are auto-split and transferred on-chain, no manual step.
3. AI Financial Advisor Chat — ask balance/cashflow questions in natural language, answered from on-chain data + Supabase.
No frontend, no dashboard. It exposes a real MCP server (POST /mcp, JSON-RPC 2.0) billed per-call via x402 (0.2 USDT/call), plus a free-form chat webhook (POST /webhook/okx) for demo purposes. Built with Node.js/TypeScript, Express, Gemini function calling, viem, and Supabase, running on X Layer.
