What is Rainbow?

Rainbow is a Wallet Integration for Polymarket that added native in-wallet Polymarket trading to its iOS app in December 2025, letting Rainbow users trade prediction markets without leaving the wallet or switching to a browser. Rainbow itself is a mobile-first, design-led Ethereum wallet supporting Ethereum, Polygon, Optimism, Arbitrum, BSC, Base, Zora, and custom EVM RPCs — founded in 2019 by Christian Baroni, Jin Chung, and Mike Demarais. The company is headquartered in New York and is a Y Combinator alumnus; it raised an $18M Series A led by Seven Seven Six (Reddit co-founder Alexis Ohanian's fund) following a $1.5M seed, plus a reported additional $19.5M private round with a planned CoinList ICO at a $100M FDV. On Polymarket's Builder Program leaderboard Rainbow ranks #31 on the 1-month at $1.56M routed from 356 monthly active users, and #31 all-time at $8.04M from 2,537 cumulative users — strong organic retail traction consistent with consumer-wallet distribution.

Rainbow is a consumer-grade mobile Ethereum wallet built around design quality and EVM-network coverage, supporting Ethereum, Polygon, Optimism, Arbitrum, BSC, Base, and Zora plus custom EVM RPCs. The company was founded in 2019 by Christian Baroni (CEO), Jin Chung, and Mike Demarais and is headquartered in New York; co-founders previously worked at Stripe, Microsoft, and eBay. Rainbow is a Y Combinator company.

The Polymarket integration shipped in December 2025 inside Rainbow's iOS app, following a similar in-wallet integration by MetaMask. Rather than redirecting users to polymarket.com, the integration surfaces Polymarket prediction markets directly inside the wallet experience, leveraging the wallet's existing key management and gas-sponsored UX. Q4 2025 roadmap messaging explicitly framed this as 'Prediction Markets Powered by Polymarket.'

Rainbow has raised an $18M Series A led by Seven Seven Six — the venture fund founded by Reddit co-founder Alexis Ohanian — following a $1.5M seed. More recently Rainbow raised an additional $19.5M in private funding, with reports of a planned CoinList ICO at a $100M FDV and an RNBW token. Combined with the Polymarket integration, this places Rainbow among the larger consumer-wallet routers on the Builder leaderboard.

On-chain Polymarket traction: #31 on the 1-month builder leaderboard with $1.56M routed from 356 monthly active users; #31 all-time at $8.04M cumulative from 2,537 users. The high active-user count for the volume tier indicates real retail traction — consistent with a wallet integration that exposes Polymarket to existing Rainbow users rather than dedicated prediction-market traders.

How to verify Rainbow

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 — $Rainbow 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.
