# Fees and costs

> All the fees that touch a tonch Jetton — launch fee, curve fee, graduation cut, and gas estimates.

This page enumerates every fee a deployer or trader pays. Numbers are exact for the current factory configuration (factory address: see [Reference / Contracts](/reference/contracts)).

## Launch fee — 3 TON

Paid once by the deployer, at launch, to the factory. Covers:

* Gas for deploying the curve contract, Jetton master, LP locker.
* Storage rent prepayment for the new contracts.
* The factory's own gas overhead.

The fee is hard-coded in the factory's state and visible via `get_factory_config` → `launch_fee`. It cannot be changed per launch.

If the launch transaction reverts after the factory accepts the message, the fee is **not refunded**. If the transaction never sends (wallet refuses, RPC timeout), no funds move.

## Curve trading fee — 1%

Applied to every buy and sell on the bonding curve. Stored in the factory state as `curve_fee_bps = 100` (100 basis points = 1%).

* **On buy:** of the TON sent by the buyer, 1% is deducted before the curve math computes Jettons out. The buyer gets fewer Jettons than the pre-fee price would suggest.
* **On sell:** of the TON the curve would owe the seller, 1% is deducted before the seller receives it. The seller gets less TON than the pre-fee price would suggest.

The fee accrues in the curve contract's `accumulated_fees` state field. It does not move until the deployer triggers `op::sweep_fees` after graduation.

For a curve that fills with moderate volume, the deployer collects roughly 1% of the cumulative TON traded — for a 1,000 TON curve, that's about 10 TON, plus any extra volume from sells (which also pay the fee).

## Graduation treasury cut — 10%

Applied once at graduation, to the curve's accumulated TON. Stored in `params.fc` as `graduation_treasury_cut_bps = 1000` (1000 bps = 10%).

```
treasury_cut = real_ton × 10%  ≈ 100 TON (for a 1,000 TON graduation)
```

The cut is sent to the **protocol treasury** address (visible on the factory's `get_factory_config`).

The remaining 90% (≈ 900 TON) seeds the DeDust pool's TON side. Combined with the 200M AMM-reserved Jettons, these form the initial DeDust pool reserves.

## DeDust trading fees — variable

After graduation, all trading happens on DeDust v2. DeDust applies its own per-pool fee (typically 0.05%–0.30% depending on the pool's volatility configuration). This fee goes to DeDust LPs and DeDust's own protocol cut, not to tonch.

tonch does not collect any fee on post-graduation trades. The protocol's revenue from a token is bounded by the 3 TON launch fee + the 10% graduation cut.

## Gas estimates

These are rough estimates; actual gas depends on TON validator rates at the time.

| Action                                 | Approximate gas                                    |
| -------------------------------------- | -------------------------------------------------- |
| Connect wallet (TonConnect)            | 0                                                  |
| Buy on curve                           | 0.05–0.10 TON                                      |
| Sell on curve                          | 0.10–0.15 TON (TEP-74 transfer + curve response)   |
| Launch                                 | 0.5–0.7 TON (separate from the 3 TON fee)          |
| Dev-buy                                | 0.05–0.10 TON                                      |
| Graduate (keeper-triggered)            | \~0.5 TON, paid by the keeper, not by the deployer |
| Sweep fees (deployer, post-graduation) | 0.05 TON                                           |
| DeDust trade                           | DeDust's standard gas (\~0.2 TON)                  |

When you initiate a transaction, tonch's frontend pads the value with a small gas buffer so the action lands. Any unspent gas refunds back to your wallet.

## Worked example

A deployer launches a token, dev-buys 5 TON, and the token graduates after total cumulative trading volume of 1,200 TON (some buying pressure followed by some selling). Outflows:

* **Deployer pays:** 3 TON (launch) + 5 TON (dev-buy) + \~0.7 TON (gas) = **\~8.7 TON out**.
* **Deployer gets back at graduation (sweep fees):** 1% of 1,200 TON cumulative volume = **\~12 TON** in claimable fees.
* **Plus:** the deployer's dev-bought Jettons, now tradeable on DeDust.

Net: deployer paid \~8.7 TON, claimed \~12 TON in fees, owns whatever Jetton position the dev-buy bought (free option on the post-graduation price).

The protocol's revenue from this token: 3 TON launch fee + 100 TON graduation cut = **103 TON**.

The DeDust pool's reserves: 900 TON + 200M Jettons. LP locked permanently.
