Model limits: This is an estimate, not an order quote. Funding can change each hour; slippage depends on the live book; aligned-quote, HIP-3, builder and maker-rebate rules can change the result. Negative funding is shown as a credit.
Method
Every line has a different source of uncertainty.
Fee tiers are deterministic once your tier and product are known. Funding is path-dependent. Slippage is market- and size-dependent. Bridge and additional interface costs belong outside the protocol fee.

Referral savings
Four percent of remaining eligible trading fees. No discount is applied to funding, slippage, bridge, vault or additional fees.

Funding and execution
Funding accepts a negative credit. Slippage is entered in basis points for each leg and remains independent of maker/taker classification.
