# Backend wallets

Backend wallets are **developer-controlled** wallets managed within your server environment.
Unlike client-side wallets—where the user holds the keys and must authorize every interaction—backend wallets allow your application to programmatically sign transactions and manage assets.

## Choosing the right wallet

Understanding the trade-offs between backend and embedded wallets is key to your architecture:

| Feature | Backend wallets | Embedded wallets |
| :--- | :--- | :--- |
| **Control** | Developer-controlled (API) | User-controlled (PKI) |
| **Primary use** | Automation, permissions, treasury | User transactions |
| **Signing** | Programmatic | User-authorized |
