Understand the estimate
RobinSwap app fee
One flat 0.5% on swaps and bridges. For example, a $100 trade has a $0.50 app fee. The quote’s output already reflects this fee.
Network cost
The source network charges gas. The final wallet estimate depends on the account and operation; an ERC-20 approval can add another transaction.
Estimated output
The amount quoted for the receiving asset reflects the execution rate and applicable costs. Market prices, available liquidity and timing can change it.
Why the total value difference can exceed 0.5%
The app fee is one part of the quote. Network gas and the execution price also affect the value you receive. The calculator compares the quoted input value with the output value and includes the quoted network cost once. It does not add the app fee a second time.
This comparison includes price differences and price impact, so it is not a pure fee total. The USD figures are estimates. If a required USD value is unavailable, the tool leaves the comparison unavailable instead of treating it as zero.
Keep native currency for gas
Robinhood Chain uses ETH. For a bridge deposit, keep the native gas currency on the network you send from. A stablecoin balance by itself may not cover that transaction.

Is this a guaranteed execution price?
No. This is a preview requested without your wallet. Quotes can change and your account may need an approval. The app requests a fresh quote before you confirm.
What does minimum received mean?
It is the quoted output floor after the selected slippage tolerance, subject to the route’s execution terms. It is not a separate fee or a promise that a failed trade will complete.
Is slippage added to the app fee?
No. Slippage is a limit on how far execution may move from the quote. It is not a fixed charge. The calculator uses a displayed tolerance of 3%; the app lets you review and adjust it.
