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)

Metrics must include the method and limitations to prevent misleading interpretation.
