# Introduction

> Learn what Reinx is and how it works

Reinx is the financial command center for your AI workforce. It gives each AI agent its own funded wallet — with spending controls enforced at the platform level, not by the agent's code.

## How it works

Your agents connect to Reinx through the MCP server or REST API. Each agent gets:

* A **crypto wallet** (non-custodial, USDC on Base/Polygon/Arbitrum/Optimism + Solana) for payments and agent-to-agent transactions
* **Independent spending rules** — per-payment limits, recipient controls, velocity caps, approval thresholds
* A **virtual card** (Visa & Mastercard) for merchant payments — launching with the card program

Every transaction is checked against your rules by Reinx's infrastructure before any money moves. Even a fully compromised agent cannot bypass its spending controls.

## Key concepts

| Concept            | Description                                               |
| ------------------ | --------------------------------------------------------- |
| Crypto Wallets     | Non-custodial wallets, USDC-native, gas sponsored         |
| Virtual Cards      | One card per agent, network-enforced limits (coming soon) |
| Spending Policies  | Six layers of protection, deterministic enforcement       |
| Approve/Deny       | Human-in-the-loop for transactions above your threshold   |
| Agent Health Score | Behavioral trust score (300–850), coming soon             |

<Info>
  All financial controls are enforced by infrastructure, not by the agent's code. Even a fully
  compromised agent cannot bypass its spending rules.
