The swap fee
Spiral embeds a 10 bps fee on the swap inside each leverage transaction (charged on the input token). It’s already baked into the built transaction — you don’t add anything.Revenue share
Your API key attributes every build to your partner profile. Revenue share is reconciled off-chain against on-chain volume, per your agreement — you don’t route fees on-chain or handle any settlement in your integration.Attribution is captured at build time as a lead indicator; settled amounts are reconciled against actual on-chain execution. You never touch the fee flow — it’s transparent to your integration.
What you owe your users
Nothing beyond the strategy’s own economics. The position preview (positionPreview.expectedLeverageApy) and the swap’s priceImpactPct already reflect real, net figures — show them as-is.
