Understanding fees
Understand how protocol, developer, and onramp fees work with Universal Bridge.
To monetize applications or games, you are able to set a developer fee on each crypto-to-crypto or swap transaction. You may set this percentage through Project > Universal Bridge > Settings.
Our protocol fee is a flat 30 basis points (0.30%) applied on the source token amount. This fee is independent of network gas fees and does not fluctuate.
You can configure who pays the protocol fee for buy or sell transactions by specifying the input amount sell or buy.
See full reference for buy and sell.
You can configure who pays the protocol fee for transfers or purchase mode using the feePayer setting. This affects the
total amount paid by the user and the amount received by the destination (e.g., a seller, app, or partner).
feePayer=buyer (Default) i.e. the user covers the protocol fee.
Example: If the source token is 10 USDC, the user pays 10.30 USDC.
-
thirdweb receives: 0.30 USDC
-
Receiver receives: 10.00 USDC
feePayer=receiver i.e. the receiver covers the protocol fee.
Example: The user pays 10.00 USDC.
-
thirdweb receives: 0.30 USDC
-
Receiver receives: 9.70 USDC
When onramping to crypto using the Universal Bridge, a fee is charged by the third-party provider. This fee is determined by the provider and is typically a percentage of the amount being onramped. This fee may vary based on the provider and payment method used.
There are no protocol fees on onramp transactions.
