# Liquidity provision with Ledger

## Liquidity Provision with Ledger

This guide explains how to add liquidity on [STON.fi](https://ston.fi/) using a **Ledger hardware wallet**.

⚠️ **Note:** Ledger signs only one transaction at a time. Adding liquidity often requires **multiple signatures**. Don’t worry — the [STON.fi app](https://app.ston.fi/) detects that you use a Ledger wallet and guides you step-by-step. Your funds are always safe, even if you stop halfway.

***

### ✅ Before You Start

Make sure: you have

* Your **Ledger device set up**
* Ledger **connected to Tonkeeper** ([see guide](https://tonkeeper.helpscoutdocs.com/article/86-how-to-connect-ledger-to-tonkeeper))
* A stable internet connection

### Step 1. Connect Ledger to [STON.fi](https://ston.fi/)

1. Open [STON.fi app](https://app.ston.fi/).
2. Click **Connect Wallet → TonKeeper → Ledger wallet**.

### Step 2. Choose a Pool

There are two ways to choose a pool:

* **Direct**. Go to [Provide liquidity page](https://app.ston.fi/liquidity/provide?utm_source=chatgpt.com) → pick a token pair (e.g., **TON/STON**) → click **Select pair**.

### Step 3. Select Provision Mode

You can provide liquidity in two modes:

#### 🔹 Balanced Mode (default)

Provide equal value of both tokens.

* Enter the amount of Token A → Token B is calculated automatically.
* Click Preview liquidity provision → **Confirm liquidity provision**.

* Sign two transactions with Ledger:
* Token A deposit\ <br>
* Token B deposit\
  \
  ⚠️ Keep the confirmation window open until both signatures are complete.\ <br>

#### 2. Arbitrary Provision (optional)

Supply tokens in any ratio. The pool automatically balances your contribution to align with the required ratio.

* You can provide one or two tokens.
* Sign one transaction (if one token) or two transactions (if two tokens).
* Click Preview liquidity provision → Confirm liquidity provision.

* Sign transactions with Ledger as prompted.

✅ That’s it! You’ve successfully added liquidity on [STON.fi](https://ston.fi/) with Ledger.

❌ Limitations. Pool creation is not supported with Ledger yet. You can only add liquidity to existing pools.

### Special Cases with Ledger

Since Ledger signs one transaction at a time, you may see intermediate states:

Case 1: Signed only one token

What to do:

* Sign the second transaction to finish, OR
* Use Arbitrary provision to complete the operation with a single token, OR
* Refund the first token back to your wallet.

Case 2: Both tokens sent but provision not completed

What to do:

* Complete liquidity provision with already sent tokens, OR
* Add more tokens to increase your LP position, OR
* Refund tokens back to your wallet.

👉 Every action requires a Ledger signature.

👉 Your funds remain safe at all times.
