# Fees & Limits

> Learn how Rhino charges fees, how deposit and withdrawal limits are enforced, and how the Advanced Fee & Limit Management extension gives you control over both.

## How fees work

Rhino charges a per-transaction fee composed of two components:

| Component           | Description                                                                                       |
| ------------------- | ------------------------------------------------------------------------------------------------- |
| **Bridge fee**      | A percentage of the transferred amount, volume-based and agreed at the account level              |
| **Destination gas** | The cost of executing the settlement transaction on the destination chain, passed through at cost |

Fees are quoted before a transaction executes. Rhino honors the quoted fee until the quote expires — there are no surprises at settlement.

### Default fee behaviour

By default:

* Fees are deducted from the deposited amount. The recipient receives the deposited amount minus the total fee.
* In **receive mode**, the sender pays a slightly higher amount so the recipient receives an exact specified amount. Fees are absorbed in the extra amount paid.

## Deposit limits

### Bridge & Swap

| Limit type                  | Value                                          |
| --------------------------- | ---------------------------------------------- |
| **Minimum deposit**         | No minimum                                     |
| **Maximum instant deposit** | $100k–$ 1M USD equivalent (depending on route) |
| **Maximum slow deposit**    | Up to \$10M USD equivalent                     |

### Smart Deposit Addresses

| Limit type                  | Value                                                                                      |   |
| --------------------------- | ------------------------------------------------------------------------------------------ | - |
| **Minimum deposit**         | \$0.5 on EVMs and Solana<br />\$5 USD equivalent on Ethereum and Tron (editable on demand) |   |
| **Maximum instant deposit** | $100k–$ 1M USD equivalent (depending on route)                                             |   |
| **Maximum slow deposit**    | Up to \$10M USD equivalent                                                                 |   |

Deposits below the minimum or above the maximum are not processed. With the [Advanced Fee & Limit Management](/get-started/extensions/advanced-fee-management) extension, limits can be adjusted by agreement.

## Advanced Fee & Limit Management (Extension)

The [Advanced Fee & Limit Management](/get-started/extensions/advanced-fee-management) extension is available for accounts that need more control over fee handling. It is available in Free and Premium tiers.

### Fee sponsorship

Clients can configure Rhino to sponsor the bridge fee on behalf of their end users. The user pays nothing; the client absorbs the cost. This is useful for onboarding flows where friction needs to be minimised.

### Fee markup

Clients can add a configurable markup on top of the standard Rhino fee. Rhino collects the total fee (its own fee plus the markup) and remits the client's portion via end-of-month invoicing. This allows clients to generate revenue from their bridge integration without operating a fee collection system themselves.

### End-of-month invoicing

Rhino consolidates all collected client markup fees and issues a monthly invoice. Payment is made directly to the client's designated wallet or bank account, depending on the arrangement.

### Limit configuration

With the Advanced Fee & Limit Management extension, minimum and maximum limits can be adjusted by agreement. Contact your account representative to discuss non-standard limits.

## Fee transparency in the API

Current fees for any bridge can be queried in real time:

* **Bridge & Swap:** The `/bridge/quote/user` and `/bridge/quote/public` endpoints return a `fees` object in every quote response, including the breakdown of bridge fee and gas cost.
* **Smart Deposit Addresses:** Fees for SDA deposits can be estimated via the quote endpoints using the expected deposit amount and token.
