# Cost & Fee Structure

> Learn about Relay's cost and fee structure

In any given token swap or bridge powered by Relay, there are four potential fee and cost components:

1. **Execution Cost (formerly Execution Fees)**

   Covers execution costs including network gas on the origin and/or destination chain, and includes:

   * \$0.02 flat fee — always included
   * Destination (fill) gas estimate — always included, covers transaction fulfillment on the destination chain
   * Origin gas estimate — only included for gasless transactions, covers transaction submission on the origin chain on the user's behalf

   For regular (non-gasless) transactions, the user pays origin gas directly from their own wallet to the network — it's not part of the Execution Cost.

2. **Swap Cost (formerly Swap Fees)**

   Covers payments to liquidity providers that facilitate cross-asset and cross-chain token swaps, and includes:

   * DEX fees
   * DEX swap impact
   * Solver cross-chain rebalancing fees

   Note: Hyperliquid charges a \$1 activation fee for new deposits. Relay cannot change this fee — it is passed through to users.

3. **Platform Fees (formerly Relay Fees)**

   A flat basis point fee charged for using the Relay API gateway and related services, including via the Relay.link frontend.

         <td>0.15%</td>
       </tr>
     </tbody>
   </table>

   Relay integrators can receive a revenue share on the Platform Fees. The revenue share varies by asset pair type and volume tier, as detailed below. To qualify, integrators must:

   1. Pass an API key in the Relay quote
   2. Complete Know Your Business (KYB) verification
   3. Exceed \$10,000,000 in aggregate U.S. dollar volume over a trailing 30-day period
   4. Provide an EVM wallet address to receive revenue share

   The revenue share cannot be used to discount the Relay product to end users.

       </tr>
     </tbody>
   </table>

   *\* The Revenue Share Volume Tier is calculated based on the aggregate U.S. dollar value of the transactions for the trailing 30 days.*

   **Relay Transaction Types:**

   * **Token Bridge:** a token bridge transaction. Examples:
     * USDC on Arbitrum to USDC on Base
   * **Same-Chain Wrap/Unwrap:** a 1:1 conversion on the same chain between a native asset and its tokenized equivalent via a single smart contract. Wrapping locks the native asset and mints the wrapped token; unwrapping burns the wrapped token and releases the native asset. Examples:
     * ETH to WETH on Ethereum
     * SOL to WSOL on Solana
     * POL to WPOL on Polygon
     * BNB to WBNB on BNB Chain
   * **Stablecoin swap:** same-chain or cross-chain swaps between any pair of these stablecoins: USDC, USDC.e, USDT, USDT0, DAI, USDe, USDS, USD1, PYUSD, USDG, mUSD, USDm, USDH, pUSD, and PlumeUSD (each, a "Major Stablecoin"). Examples:
     * USDC to USDT on Ethereum
     * USDC on Optimism to USDT on Solana
   * **Major swap:** same-chain or cross-chain swaps between any pair of these tokens: ETH, WETH, BTC, WBTC, SOL, WSOL, POL, BNB, and PLUME (each, a "Major Token"), and between any Major Token and any Major Stablecoin. Examples:
     * ETH to POL on Polygon
     * ETH on Ethereum to SOL on Solana
   * **Minor swap:** same-chain or cross-chain token swaps between any pair of tokens that are not a Major Stablecoin or Major Token. Examples:
     * LINK to UNI on Ethereum
     * AVAX on Avalanche to Aster on BNB Chain

4. **App Fees**

   Fees added on top of a Relay quote by the integrator.

If you are interested in learning how app fees work, and how you can add them to your quotes please check out our [App Fees Doc](/features/app-fees).

*Please note that the above fee structure applies to standard cases. In certain cases, such as route-specific campaigns or promotions, different fees may apply.*

## Fees in the API

[`GET /requests/v3`](/references/api/get-requests) returns a request's fees in the `data.fees` object, with `quoted` (estimated at quote time) and `actual` (computed at fill time) values. It breaks fees down into the following components:

**execution** - Execution costs covering network gas on the origin and/or destination chain plus the flat fee.

**swap** - Swap costs from cross-currency and cross-chain exchange, including DEX fees, swap slippage, and solver rebalancing.

**platform** - The Platform Fees, a flat basis-point fee charged by Relay for routing and meta-aggregation services.

**app** - App fees added on top by the integrator, when present.

**sponsored** - The portion of fees the integrator subsidizes on behalf of the user via [Fee Sponsorship](/features/fee-sponsorship).

<Tip>
  When displaying fees to users, we recommend mapping the `data.fees` fields as follows:

  * **execution** → Execution Cost
  * **swap** → Swap Cost
  * **platform** → Platform Fees
  * **app** → App Fee
</Tip>

<Note>
  In the quote API and [`GET /requests/v2`](/references/api/get-requests-v2), this same breakdown is returned as the `expandedPriceImpact` object, and the **platform** component is named **relay**.
</Note>

## Fee Sponsorship

Integrators with [Fee Sponsorship](/features/fee-sponsorship) enabled can subsidize fees for their users. By default, setting **`subsidizeFees`** to `true` sponsors all fee components.

For more granular control, use the **`sponsoredFeeComponents`** parameter in the quote request to choose which specific fee components to sponsor. This allows you to sponsor some components (e.g. `execution` and `platform`) while letting the user pay others (e.g. `swap`).

Deposit addresses do not support `sponsoredFeeComponents`.

See the [Fee Sponsorship Doc](/features/fee-sponsorship) for setup details.

## Deprecated: Fees Object

<Warning>
  The `fees` object is deprecated. It is still returned from the quote API and the [`GET /requests/v2`](/references/api/get-requests-v2) API for backwards compatibility, but it only reports Relay-related fees and does not reflect the full cost of a request. Do not rely on it for new integrations.

  To understand or display the complete fee breakdown of a request, use the [`data.fees`](#fees-in-the-api) object in `GET /requests/v3` (or `expandedPriceImpact` in the quote API and `GET /requests/v2`) instead, which covers execution, swap, platform, app, and sponsored fees.
</Warning>

The deprecated `fees` object is segmented into the following fields:

**relayerService**: The service fee paid to the relayer to facilitate execution.

**relayerGas**: The gas fee given to the solver to pay gas fees on the destination chain.

**relayer**: The sum of the relayerService and the relayerGas.

**app**: Third party fees added on top of the existing fees, this fee is added by app developers and accrues offchain to minimize gas costs.

**subsidized**: The Fees in the order that are subsidized by the integrator.
