# Margin Swap

> user_margin_swap — Jupiter v6 from the margin vault with a post-swap health check.

```text theme={null}
user_margin_swap(amount_in, min_amount_out, route_account_count, route_data)
```

The program signs the vault with margin seeds, forwards `route_data` to Jupiter, then revalues the account.

Token-2022 transfer fees: the client sizes `amount_in` so the **received** delta covers the route. Do not assume `amount_in` equals the Jupiter exact-in after fees.

`min_amount_out` is the slippage bound. Failed health after a would-be swap aborts the whole transaction.

Perps and Farm closes reuse this primitive (or the Lite unwind that embeds a route).
