The 32-byte hash Polymarket uses to attribute volume to this builder on-chain.
0x5287fbdf8c2e5df405c52330a332c6bf9343ad9d5e6ecf14dea70548e9375b15 What is hj?
hj is a verified participant in the Polymarket Builder Program (builder code 0x5287fbdf8c2e5df405c52330a332c6bf9343ad9d5e6ecf14dea70548e9375b15) with the minimum possible on-chain footprint: rank #371 all-time at $20 cumulative volume from a single lifetime user. The two-character builder name is impossible to search effectively (queries return billions of unrelated results across every domain), and there is no logo image attached in the manifest. The combination of a two-letter handle, a single $20 transaction, and a single lifetime user is the canonical signature of a developer-probe pattern — a builder registered a code, sent a single small test trade to confirm the integration works, and then either abandoned the effort or moved on to a different builder code. We classify hj as a developer probe rather than a published product. The page will only be expanded if the owner identifies themselves or a corresponding product launches with publicly discoverable branding.
hj is a verified participant in the Polymarket Builder Program with builder code 0x5287fbdf8c2e5df405c52330a332c6bf9343ad9d5e6ecf14dea70548e9375b15. Its on-chain attribution is the absolute minimum possible: rank #371 all-time at $20 cumulative volume from a single lifetime user, with no monthly activity to speak of.
The two-character builder name 'hj' is impossible to search effectively — generic two-letter strings return billions of unrelated results across every domain (chemistry, cricket statistics, surnames, abbreviations) and no Polymarket-relevant hit was discoverable in any search variant.
The combination of (a) a two-letter handle that reads as developer-initials, (b) a single $20 transaction, (c) a single lifetime user, and (d) no logo image attached in the manifest is the canonical signature of a developer-probe pattern. The most likely story: a builder registered a code, sent a single small test trade to confirm the Builder Program rebate-attribution integration works correctly, and then either abandoned the effort, moved on to a different (named) builder code, or never came back. Polymarket's Builder Program is free and permissionless, so test-and-abandon codes are common in the long tail of the leaderboard.
We classify hj as a developer probe rather than a published product, and present this entry transparently as such. The page will only be expanded if the owner identifies themselves publicly or a corresponding product launches with discoverable branding linked back to this builder code.

hivy
Polymarket Builder Program participant with $28 lifetime volume (pre-launch scale); the candidate hivy.com is a French real-estate platform, a confirmed name collision.

Tipmarket
Polymarket Builder Program participant at tipmarket.com; site returns no crawlable content and no third-party Polymarket directory references the brand. Effectively a registered but unlaunched builder.

Polymarket builder identifier with effectively no on-chain activity ($35 lifetime from 1 wallet) — consistent with a developer test registration or stealth pre-launch integration.

What-exchange-builder-02
Polymarket Builder Program test/staging integration with the slug 'What-exchange-builder-02' — almost certainly an internal developer probe, not a public consumer product.

How to verify hj
- On-chain attribution — every Polymarket Builder routes via an order that includes their
builderCode. The hash above is checkable on Polygon against Polymarket's CTF Exchange. - Polymarket's own verification — $hj carries the official ✓ verified flag in the data API.
- Cross-check Polybot Arena — polybot.arena tracks wallet-level P&L for builder-tagged bots. If a builder claims specific performance, their wallet should be findable there.
- Tier-2 patterns to avoid — we flag builders that match the Tier-2 pattern (no public team, no verifiable claims, recurs across affiliate-SEO listicles). See our /methodology page for the full criteria.
