0x2f7eca164dbf71fa1b9de2cd50101befcd8c578540d509059d3977a9cc113aec DoubleUp is a Polymarket-verified builder whose product surface is not publicly identifiable as of May 2026. The closest publicly searchable candidate is doubleup.fun, a decentralized casino on Sui offering classic casino games with no KYC, but its public marketing does not mention Polymarket and cannot be confirmed as the source of the on-chain DoubleUp activity. The other DoubleUp candidate — the DoubleUp (UP) ERC-20 token tracked on CoinGecko / 3commas — is unrelated to Polymarket builder routing. On the Polymarket builder leaderboard DoubleUp shows a striking signature: only #201 monthly with $395 routed and 1 active user, but #83 all-time at about $1.03M cumulative across just 2 users. That ~$1M lifetime / 2-user pattern is the classic on-chain fingerprint of a single OTC desk, whale router, or internal market-maker rather than a retail-facing app — so we deliberately leave the URL null pending direct confirmation.
DoubleUp is enrolled in the Polymarket Builder Program but the doubleup.com URL captured in the manifest could not be verified as belonging to this builder — the homepage returns no crawlable Polymarket-related content and no third-party Polymarket directory references the brand.
The closest publicly searchable candidate is doubleup.fun, a decentralized casino on Sui offering classic casino games with no KYC. However its public marketing does not mention Polymarket integration and we have not confirmed any link to the on-chain DoubleUp builder code. A separate "DoubleUp" token (UP) on CoinGecko / 3commas is also unrelated to Polymarket routing.
On-chain traction is the most useful evidence: #201 on the 1-month builder leaderboard with $395 routed and only 1 active user, but a much larger all-time footprint at #83 with $1.03M cumulative across 2 users. The $1.03M lifetime / 2-user signature is a classic single-whale / institutional-router pattern, not a retail product — most likely a private OTC desk, internal market-maker, or whale-only routing tool that does not expose a public homepage.
We leave url null and avoid attributing this builder to doubleup.fun or any other DoubleUp brand without source confirmation. Founders, funding and exact launch date are not publicly disclosed.
