# Qoi > Qoi is the security and governance layer between AI agents and money. Qoi Guard scans the process tree behind every agent connection and verifies code signatures against the genuine vendors, so a spoofed process can't impersonate your AI. A human sets the spending policy (daily, weekly or monthly allowances); every payment is risk-scored, and anything outside policy waits for one-tap human approval on the Qoi Guard app. Keys stay on the user's device; payments settle on Base (an Ethereum layer 2). Agents connect over MCP (Model Context Protocol) and can pay for x402-protected, pay-per-use resources. Built by Qoi Pond Ltd, a UK-registered company (Company No. 17206307). Key facts: - Governance first: Qoi is a security/governance layer (agent verification, policy, risk assessment, approvals); Qoi never holds, routes or touches user funds. - Agent verification: Qoi Guard walks the process tree of every MCP connection and checks code signatures against the genuine vendor apps; unsigned or spoofed clients fall back to manual approval. - Agent integration: any MCP-capable agent (Claude, ChatGPT agents, custom agents) can request payments through the Qoi MCP server; x402 is supported for pay-per-use APIs. - Human control: allowances are enforced before a payment moves; unusual payments require explicit approval; unanswered requests expire and nothing executes. - Audit: approvals, declines and payments are recorded in an exportable history. - Status: free macOS alpha available now; iOS TestFlight invites rolling out; public launch planned for 2027. ## Pages - [Home](https://qoi.app/): product overview, how it works, roadmap, team, FAQ, early-access signup - [Download Qoi Guard](https://qoi.app/alpha.html): macOS .dmg download, install steps, checksum verification, alpha FAQ - [Privacy Policy](https://qoi.app/privacy.html): no cookies, no analytics; email collected only for early-access invites - [Terms of Use](https://qoi.app/terms.html) ## Contact - Email: hello@qoi.app - GitHub: https://github.com/qoipond - X: https://x.com/qoiapp
