# Fees

Hinkal charges a privacy fee on most operations, taken as a percentage of the transaction amount and expressed in basis points (1 bps = 0.01%, so 25 bps = 0.25%). Network gas is separate and paid as usual.

**Supported networks**:

* Ethereum
* Polygon
* Solana
* Base
* TRON
* Arbitrum
* Tempo
* BNB Chain
* Robinhood
* Arc
* Arc Testnet
* [External networks](/hinkal/ecosystem/external-chains-support.md) as destination (for public transfers)

#### **Structure**

| Operation                                                  | Fee      |
| ---------------------------------------------------------- | -------- |
| Send from your wallet to a wallet address                  | 25 bps   |
| Bridge & Send from your wallet (cross-chain send)          | 25 bps   |
| Send from your wallet to a Hinkal deposit address          | **Free** |
| Top up (wallet → private balance)                          | **Free** |
| Send from your private balance to a Hinkal deposit address | 25 bps   |
| Bridge & Send from your private balance (cross-chain send) | 25 bps   |
| Send from your private balance to a wallet address         | 25 bps   |
| Withdraw (private balance → your wallet)                   | 25 bps   |
| Swap from your wallet                                      | 25 bps   |
| Swap from your private balance                             | 25 bps   |

***Moving funds from your wallet into a private balance is free: your own with Top up, or a recipient's when you send to their deposit address on the same network and token. Every other send, Bridge & Send, swap, and withdrawal is charged the Hinkal fee.***

#### **Partner key**

If your company is a [Hinkal Partner](/hinkal/hinkal-partner/overview.md), you can get your agreed Hinkal fee in Pay:

1. Select the **Hinkal logo** in the top left and choose **Partner Key**.
2. Paste the key from the **API Keys** page of Hinkal Partner and choose **Apply**.

Every operation above that's charged 25 bps then uses your agreed rate instead, and the summary shows it. Free operations stay free. Paying a payment link and claiming a payment use your rate too.

Pay remembers the key in that browser. To stop using it, open **Partner Key** again and choose **Remove key**. Pay checks the key when the page loads. If the key is replaced or your agreed rate changes, **reload Pay** to see it: a replaced key is removed and Pay goes back to the standard fee, and a changed rate shows the new value. Until you reload, Pay keeps using the rate it loaded with. See [Partner key](/hinkal/hinkal-partner/api-keys.md#partner-key).

#### **Summary**

The Hinkal fee and network fee are shown in the summary before you confirm. Bridges can also show a separate **Bridge fee**. When you send from your wallet balance to a mix of wallet addresses and deposit addresses, the summary lists the Hinkal fee for public and private recipients separately, and private recipients are free.
