# Supersmooth Fee Schedule and Free Features

> Complete Supersmooth fee schedule including Position Swap Fee tiers, Borrow Spread, Yield Loop Spread, Conversion Fee, Perps Builder Fee, and what is free.

Supersmooth discloses every fee in the transaction preview before you confirm, and itemizes every fee in position history. Gas costs and venue-level costs (protocol interest, funding rates, and liquidation penalties) are set by the underlying networks and protocols, not by Supersmooth.

## Fee schedule

| Fee | Applies to | Rate |

| Borrow Spread | Borrow and Multiply positions while open | Venue borrow rate × 1.075 |
| Yield Loop Spread | Yield Loop positions while open | Venue borrow rate × 1.5%, capped at 10 bps APR |

## What is free

Supersmooth charges no fee for the following, by design, so that Supersmooth's incentives align with yours:

* Holding any position. Supersmooth charges no standing fees, ever.
* Standard protocol actions in native assets: deposit, withdraw, borrow, and repay.
* Yield Loop adjustments in any direction.
* Stop Loss and Trailing Stop Loss executions on Borrow positions. Supersmooth does not monetize protection.
* Migration into Supersmooth.
* Earn deposits, Earn withdrawals, and Earn holding, in native assets.
* Automation setup and automation edits, which cost gas only.
