Fair Fill
Perp execution quality check
Paste a perp fill and Autonom will try to resolve the fair benchmark from its own second-level price history at the fill timestamp. Positive execution cost means the fill was worse than benchmark; negative means price improvement. Optional/manual horizon marks are still supported, but Autonom can auto-fill markouts from history when available.
Compare venue performance →This is a TCA-style diagnostic, not a claim that a venue cheated you. Client-facing mode requires an Autonom exact-second historical benchmark plus a verified expected-cost model.
Tx-derived trade check
Paste open and/or close transaction signatures
Pick the perp venue, paste an open tx, a close tx, or both. Autonom will decode each provided leg and the UI will summarize the whole trade so venues that charge more at entry or exit can be compared on a round-trip basis.
Jupiter Perps tx decoder
Tx-derived Fair Fill uses the operator Jupiter decoder, including request → keeper settlement correlation when needed.
venue sent: jupiter-perps
program_id sent: omitted; operator resolves from venue
canonical program: PERPHjGBqRHArX4DySjwM6UJHiR3sWAatqfdBS2qQJu
events: InstantIncreasePositionEvent, InstantDecreasePositionEvent, IncreasePositionEvent, DecreasePositionEvent, LiquidateFullPositionEvent, LiquidatePartialPositionEvent
notes: Operator must decode Jupiter perps Anchor events/instructions from the Jupiter program. Program id is not sent from the UI unless explicitly configured; the operator should use its venue default.
