# Overview

> What you can do with the Zhentan app.

Zhentan is a smart wallet with built-in AI screening. Every transaction you initiate — whether from the app or from any DApp — passes through the same screening pipeline before it executes.

## Wallet Profiles

Your wallet is a Safe multisig with one of four [computed profiles](/technology/signing#wallet-profiles):

| Profile       | Keys                 | What it means                                                        |
| ------------- | -------------------- | -------------------------------------------------------------------- |
| **Starter**   | You                  | Instant onboarding — your signature alone executes; no screening yet |
| **Guarded**   | You + agent          | Screening always on (your key can't reach the threshold alone)       |
| **Protected** | You + backup + agent | The full model — screening by choice, override always available      |
| **Detached**  | You + backup         | Exit state — a stock Safe, agent removed                             |

Add a backup key anytime (paste an address, ENS/.bnb name, or connect a wallet — no signature needed) to move from Guarded to Protected.

## Screening Modes

| Mode                | Behavior                                                                                                                             |
| ------------------- | ------------------------------------------------------------------------------------------------------------------------------------ |
| **ON**              | Full pipeline — APPROVE / REVIEW / BLOCK on every transaction                                                                        |
| **OFF** (Protected) | Transactions queue at 1 of 2 and execute once your backup key co-signs — in-app or in the Safe app. The agent relays without signing |
| **OFF** (Legacy v1) | The agent co-signs without risk analysis — see [Legacy Accounts](/technology/legacy)                                                 |

Toggle from Settings (Zhentan Guard) or Telegram: `screening on` / `screening off`. Guarded wallets can't turn screening off — add a backup key first.

## Gas

You never need BNB — the agent relays every execution on-chain and pays gas. Your signatures authorize; the agent submits.
