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 |
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.

Advanced Fee & Limit Management (Extension)
The Advanced Fee & Limit 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
