How Pricing Works
At Houdini Swap, the quote you see is all-in. We don’t believe in “post-swap” fees. Every quote automatically accounts for:- Network (Gas) fees
- Bridge & Protocol fees
- Houdini routing commissions
What you see is what you get.You never need to calculate fees separately; we do the math for you so the amount on your screen is the amount that lands in your wallet.
Fees by Swap Type
Costs vary depending on the complexity and privacy of your route:- Onchain Swaps: Thousands of routes are queried simultaneously and we find whichever offers the best output. The rate you see already reflects competition across the market.
- No Wallet Connect: Houdini Swap finds the lower cost route across all exchange partners and the output amount shown is what you receive. Houdini Swap earns a commission back from each exchange post-swap, ensuring that the price you see is the best available price across all partner exchanges.
- Private Swaps: Our most premium service. Fees are approximately double the No Wallet Connect option because Private Swaps require two separate execution steps to fully break the on-chain link between wallets.
Market Movement & Slippage
Because execution happens after a quote is generated, the final amount may vary slightly due to normal market volatility.- Onchain Protection: Transactions revert if slippage exceeds your limit.
- CEX Route Protection: If prices move significantly during execution, the swap will automatically trigger a pause, and we will ask you whether to continue at the new rate or refund.
