Firefly is a Trading Interface built by Mask Network that combines Web3 social aggregation across Farcaster, Lens, X and Mirror with embedded Polymarket prediction-market betting and on-chain activity tracking, letting crypto-native users speculate on real-world events without leaving the social feed. The app integrates with Fileverse, Snapshot, Polymarket, Mirror and Paragraph, and has run a Polymarket Trading League with a 3,000 USDC prize pool plus daily rewards. As a Polymarket builder Firefly ranks #57 by 1-month volume with about $381.4k routed from 80 users, and #61 all-time at $2.03M cumulative across 203 users — solid retail diffusion through a social distribution channel. Mask Network was founded in 2017 by Suji Yan; Firefly was spun off as a standalone product in 2025 alongside Next.ID, and Vitalik Buterin has publicly endorsed its UX.
Firefly is a Web3 "everything app" built by Mask Network that combines social-media aggregation (Farcaster, Lens, X, Mirror), on-chain activity tracking, and prediction-market betting powered by Polymarket. It lets crypto-native users speculate on real-world events without leaving the social feed, and is one of the few Polymarket builders distributed through a consumer social product rather than a trading terminal.
On-chain traction: #57 monthly with $381.4k routed from 80 users and #61 all-time at $2.03M cumulative across 203 users — solid retail diffusion through a social distribution channel rather than power-user concentration.
Firefly integrates with Fileverse, Snapshot, Polymarket, Mirror and Paragraph. The product has run a Polymarket Trading League (Season 2 launched with a 3,000 USDC prize pool plus daily trading rewards and leaderboard incentives) — an explicit growth lever pushing social-feed users into Polymarket positions.
Mask Network (the parent) was founded in 2017 by Suji Yan, who dropped out of UIUC at age 20. In February 2025 Mask Network/MaskDAO announced a major restructuring spinning off Firefly and Next.ID into independent product lines. Vitalik Buterin has publicly endorsed Firefly's UX.

How to verify Firefly
- 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 — $Firefly 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.
