Fees
An overview of the fees in Rhinestone’s system
Rhinestone’s core onchain infrastructure and SDKs are open source and free.
The transaction infrastructure has no API fee. The stakeholders in the transaction supply chain only make money once your users are transacting. These fees are transaction fees on the principal value of crosschain transaction.
Same chain intents are free. Solvers are incentivised to fill these transactions for two reasons:
-
The solver takes a small premium on gas (see below).
-
After performing same-chain intents, the solver’s capital is not locked in a settlement layer. It is instantly returned to the solver on the same chain. Therefore, there is no loss in capital efficiency from filling same-chain intents.
Fee Structure
Transaction fees are split into two categories.
-
Transfers: Is the intent segment same-chain or crosschain?
-
Swaps: Does the intent include a swap?
Transaction Fees
Transfer fees are applied to the principal value of the transaction.
| Intent type | Solver Fee | Rhinestone Fee | Settlement Layer Fee | Total |
|---|---|---|---|---|
| Same-chain | Zero | Zero | Zero | Zero |
| Crosschain | 3bps | 3bps | Zero | 6bps |
Swap Fees
We provide two forms of swaps.
-
Injected Swaps: We inject a DEX swap into the intent to perform the swap on the destination chain. Solvers include this as arbitrary call data when filling the intent.
-
Solver-based Swaps: Solvers fulfill the swap using their inventory and/or DEX routing.
Below are the fees applied to the principal value of the swap by the Rhinestone intent system.
| Intent type | Solver Fee | Rhinestone Fee | Settlement Layer Fee | Total |
|---|---|---|---|---|
| Injected Swaps | Zero | Zero | Zero | Zero |
| 1:1 Stable Swaps | 1-5bps | 1bps | Zero | 2-6bps |
| ETH-WETH Swaps | Zero | Zero | Zero | Zero |
| Solver-based Swaps* | 40bps | 10bps | Zero | 50bps |
*Solver-based Swaps are currently in beta. Pricing will be updated as the product matures.
Fee Examples
| Example Intent | Fee Breakdown |
|---|---|
| Purchase NFT on Base for 100 USDC using USDC on Arbitrum and Polygon | Crosschain transfer only. 6bps applied to the principal. Fee = 0.06 USDC |
| Swap 100 USDC from Arbitrum to DEGEN on Base through an injected swap | Crosschain transfer only. 6bps applied to the principal. Fee = 0.06 USDC |
| Swap 100 USDC to ETH using Solver-based Swaps | Crosschain transfer plus Solver-based Swap. 6bps applied to the principal + 60bps to the swap. Fee = 0.50 USDC |
Gas Fees
Gas fees are a fixed unit cost that depends on the source chain and target chain executions required to perform the intent.
The client supplies gas units. SDK helpers for the estimation are coming soon.
