# userTwapSliceFills

{% hint style="info" %}
**All data fully available from 28-07-2025. We have performed a full backfill of all fills the HL native API offered, meaning that we have full historical data for most traders except for some very high volume addresses. TWAP fills are included from 02-08-2025.**
{% endhint %}

Returns fills that were executed as part of a TWAP (Time-Weighted Average Price) order. Each fill is an individual "slice" of the TWAP execution. Only fills with a non-null `twapId` are returned.

<summary>Notes</summary>

* Returns at most 2000 most recent TWAP slice fills, ordered by time descending
* TWAP fills always have a hash of `0x000...000`
* The `twapId` field identifies which TWAP order the slice belongs to — multiple fills can share the same `twapId`
* Unlike Hyperliquid's native endpoint which wraps fills as `{ "fill": {...}, "twapId": N }`, Hydromancer returns fills in the same flat format as `userFills`
