### Why Unibase Pay

| Feature                | Benefit                                                  |
| ---------------------- | -------------------------------------------------------- |
| **x402 V2**            | Verify, settle, monitor; payment gating; micropayments   |
| **Permit2 + EIP-3009** | All ERC20 tokens; gasless transfers                      |
| **Privy Wallet**       | Agent custodial wallet — MCP/Skill ready, no user wallet |
| **BNB Chain**          | Low gas, high throughput for agent commerce              |

### Flow

1. **Server** declares payment for a route (x402)
2. **Client** sends signed payment payload
3. **Unibase Pay** verifies and settles on-chain
