PII Validation Record — polymarket-canary-tape
Date: 2026-07-22 Method: exhaustive full-database scan (read-only), not sampling. Scanner: regex sweep for 40-hex wallet addresses (excluding 64-hex ids), email patterns, and private-range IPs, over every text field in every table.
| Surface | Coverage | Result |
|---|---|---|
pm_events.payload_json |
all 27,919,423 rows | 0 wallets, 0 emails, 0 IPs |
pm_events.event_type |
full distinct enumeration (8 types) | market-channel only |
pm_events.subscription_id |
all 1,750 distinct | market/time-derived labels only |
pm_events.asset_id |
full length-distribution | 64-hex condition ids + long decimal token ids; no 40-hex |
markets (all columns incl. raw_json) |
all 23,750 rows | 4 distinct 40-hex values, all platform infrastructure (see below) |
cex_trades |
numeric columns + full distinct text sets | symbols only (BTC/ETH/SOL/XRP/DOGE-USDT) |
heartbeats, gaps, schema_version |
full | clean |
The 4 addresses in markets.raw_json are values Polymarket serves publicly
from its own Gamma API on every market object: resolvedBy (UMA CTF adapter
contracts, two versions), submitted_by (the platform market-creation
address, identical across thousands of markets), and one assetAddress
contract. They are protocol infrastructure, not user data, and are retained.
Verdict: CLEAN for publication. The Polymarket market WebSocket channel is anonymous by design; this scan verifies that exhaustively for this tape.
Addendum — additional tape files (2026-07-22)
Same exhaustive method applied to two further recorder DBs:
| File | Window | pm_events scanned | Result |
|---|---|---|---|
polymarket-recorder-tape-vantage-b-20260603-20260701.db.zst |
2026-06-03 to 2026-07-01 (second vantage point, overlaps canary) | 33,300,844 / 33,300,844 | 0 wallets / 0 emails / 0 IPs in payloads; markets.raw_json contains only the same 2-3 platform-infrastructure addresses (UMA adapter, platform submitter) |
polymarket-recorder-tape-early-72h-20260430-20260503.db.zst |
2026-04-30 to 2026-05-03 (early 72h snapshot, pre-canary) | 531,990 / 531,990 | 0 wallets / 0 emails / 0 IPs in payloads; markets.raw_json contains exactly 2 distinct addresses, both platform infrastructure |
Verdict for all three files: CLEAN for publication.
