0x11a22276beb720e66a072cba8b8e74cded60afda510af535b947b81a1b81a883 What is MetaMask?
MetaMask is a Wallet Integration builder on Polymarket: the most-installed Web3 wallet routes prediction-market trades from its in-wallet dApp surface, attributing the resulting order flow to its builder code. Built and maintained by Consensys since September 2016, MetaMask reports 100M+ users and over 5B transactions, and announced native Polymarket integration in 2025 letting users trade prediction markets 'in two taps' inside the wallet at metamask.io/prediction-markets. On the Polymarket Builders leaderboard it ranks #5 by 1-month volume with ~$15.76M routed and 4,007 active users — the highest active-user count of any top-10 builder, and #3 all-time at $201.49M from 27,775 cumulative users. MetaMask's traction is retail-distributed rather than whale-concentrated, reflecting its role as the default consumer access point to Polymarket rather than as a specialist trading terminal. Co-founders Aaron Davis (Kumavis) and Dan Finlay still drive the project.
MetaMask is the most-installed Web3 wallet, used by 100M+ people and used in 5B+ transactions since 2021. Its presence on the Polymarket Builders leaderboard reflects in-wallet dApp routing — users who connect MetaMask to Polymarket and trade through it count this builder, even when they never see Polymarket-branded UI. MetaMask is currently #5 on the 1-month Polymarket Builders leaderboard with ~$15.8M routed against 4,007 active users — the highest active-user count of any top-10 builder, and far more retail-distributed than the high-volume whale-routed entries like Gate.io or Polytrader Pro. The wallet itself is the product; Polymarket is one of many dApps it routes. Built and maintained by Consensys.
In 2025 MetaMask shipped native prediction-market integration at metamask.io/prediction-markets, surfacing Polymarket order books directly in the wallet UI — the deepest distribution channel any Polymarket builder has ever had, and the reason its retail user count dwarfs every specialist terminal.
Verification: URL confirmed via WebFetch; 100M+ user count and 5B+ transactions cited from metamask.io's own homepage. Polymarket-verified via the official Builder Program.

How to verify MetaMask
- 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 — $MetaMask 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.
