Determine whether April prints without receipts were resubmitted under alternate transaction hashes

Determine whether Polymarket trade prints from April 2026 that lack a settled counterpart under their recorded transaction hash were resubmitted under another transaction hash, using evidence beyond transaction receipts alone.

Background

The paper matches public trade prints to on-chain settlement legs using transaction hashes. Some April prints have no settled counterpart under the recorded hash, although a subset can be paired approximately with unmatched taker legs by token, side, price, size, and timing.

The authors report that receipt data alone cannot establish whether these prints were resubmitted under different hashes. Resolving this issue would distinguish venue-side resubmission behavior from missing or incomplete archival and settlement records, while also allowing the approximate second-stage matches to be assessed more reliably.
