# Proof of Execution

#### Purpose

Execution proof makes trading outcomes verifiable:

* What happened
* What it cost
* And whether the system behaved consistently

#### User-Level Export Guarantees (v1)

Users can export:

* Order history (timestamp, market, side, size, price type)
* Fill history (fill timestamps, price, quantity)
* Fees per fill (fee amount, fee currency)
* Tier applied (if applicable)
* Reject/cancel reason codes (where applicable)
