Plain English
Rainbow is a self-custody Ethereum and L2 wallet known for its design-first, consumer-friendly UX. Mobile app (iOS, Android) plus browser extension. Founded by ex-Balance team members, raised major venture funding.
How it actually works
Self-custody with seed-phrase backup. Supports Ethereum, Arbitrum, Optimism, Base, Polygon, and Zora. Built-in NFT display, token swaps via 0x/Matcha, and Hardware Wallet integration. Account abstraction support via smart wallet option. RNBW governance token launched in 2024.
What it means for you
Rainbow is the most-recommended wallet for design-conscious users entering Ethereum DeFi for the first time. UX is genuinely better than MetaMask. For HNW DeFi power-users, Rabby or Frame are more feature-dense. For introducing a family member or younger principal to self-custody, Rainbow is hard to beat.
