# Linked Signer (1CT)

**Linked Signer (1CT)** is how NadoBro signs Nado transactions on your behalf without ever touching your main wallet's private keys. The 1CT key is generated on first onboarding, encrypted at rest, and scoped to a single Nado subaccount. You can revoke it any time with `/revoke`.

#### What actually is 1CT

A **1CT** (one-click-trading) signer is a separate key that Nado recognizes as authorized to act on a specific subaccount. It cannot:

* Move funds off Nado.
* Change account ownership.
* Access any wallet other than the one that linked it.

**It can:**

* Place, modify, and cancel orders on Nado for the linked subaccount.
* Mint and burn NLP for the Nado Vault.
* Execute strategy actions inside the budget and risk limits you configured.

#### **How It Works**

* **Your private key never leaves your device.** NadoBro does not store or have access to your main wallet key.
* When you start NadoBro, a **signing key** is generated specifically for 1CT convenience. This key can only sign trades on your behalf.
* The signing key when **linked** to your main wallet, can execute trades but cannot withdraw your funds.
* You can **revoke the linked signer** at any time, instantly cutting off trade authorization.

#### Revoking

If you want to invalidate the 1CT signer — for example, you're leaving Nadobro, switching devices, or rotating credentials, just type `/revoke` in chat or use the revoke button in your wallet settings.

`/revoke` will:

* Cancel all open NadoBro-placed orders on Nado.
* Stop any running strategy sessions.
* De-authorize the 1CT key on Nado.
* Clear the encrypted key from NadoBro's store.

After revoking, you'll need to re-run onboarding to generate a new 1CT signer if you want to keep trading through NadoBro.

> 🛡️ `/revoke` is the safe "off switch" for NadoBro's signing authority. It does **not** withdraw your funds — that's a separate gateway action you take from your main wallet.

#### Emergency stop

If you want to halt activity without revoking the signer, use `/stop_all`:

* Cancels all open Nado orders placed by NadoBro.
* Closes open positions reduce-only.
* Stops all strategy sessions and copy mirrors.
* Leaves the 1CT signer in place so you can re-engage later.

#### Security Guarantees

* Your main wallet keys are **never touched** by NadoBro
* The linked signer has **limited permissions** — trading only
* Full **revocation control** — disable at any time
* All transactions are on-chain and **verifiable**
