## In One Minute

**1. Verify**

Prove an agent is real with its ERC-8004 passport. See [Know Your
Agent](/concepts/know-your-agent).

**2. Pay**

Settle in stablecoins over x402. See [x402](/protocols/x402).

**3. Connect**

Reach tools over MCP. See [the MCP server](/developers/mcp-server).

When you are ready to run a real account, the [Account
Lifecycle](/app/account-lifecycle) walks through register, fund, and permission.
