What Is Rainbow Wallet?
Rainbow is a self-custody mobile crypto wallet focused primarily on Ethereum and its ecosystem. It was built by a design-forward team with roots in consumer app development, and the aesthetic difference is immediately apparent: Rainbow looks and feels like a premium product rather than a utility tool.
Originally launched as an Ethereum-only wallet, Rainbow has expanded significantly. It now supports Ethereum Layer 2 networks (Base, Arbitrum, Optimism, Polygon, zkSync, and others), Ethereum itself, and has added support for additional networks. However, its heart remains in the Ethereum ecosystem.
Rainbow is available on iOS and Android. A browser extension was released, giving it desktop DeFi capabilities alongside its mobile-first heritage.
Rainbow is a non-custodial wallet. Your seed phrase is generated on your device, stored locally, and never sent to Rainbow’s servers. Only you have access to your funds.
Key Features of Rainbow Wallet
Beautiful NFT Display
Rainbow may offer the best NFT viewing experience of any mobile wallet. NFTs are displayed in a full-screen gallery format with rich media support — animated GIFs, MP4 videos, and high-resolution images all render properly. Collections are grouped intelligently, and you can showcase specific NFTs as featured items on your profile.
For collectors and NFT enthusiasts, this transforms the wallet from a tool into something closer to a gallery. Ethereum NFTs, Base NFTs, and NFTs across supported L2s all display correctly.
ENS (Ethereum Name Service) Support
Rainbow was built with ENS as a first-class feature from the beginning. You can:
- Display your ENS name as your wallet’s primary identifier
- Send to ENS addresses directly (type “vitalik.eth” instead of a 42-character hex address)
- View other users’ ENS profiles
- See ENS-linked avatars and profile data
For users who have invested in ENS names, Rainbow makes the experience feel native rather than bolted on.
Built-In Token Swaps
Rainbow has a built-in swap aggregator that sources liquidity from multiple DEXs to find the best rate for token swaps. You can swap any ERC-20 token without leaving the wallet. The swap interface shows:
- Expected output amount
- Price impact
- Minimum received (after slippage)
- Network fee
- Which liquidity source is being used
Swaps are available on Ethereum mainnet and all supported L2 networks.
DeFi Portfolio Tracking
Rainbow provides a clean overview of your DeFi positions including:
- Liquidity pool positions (Uniswap, Curve, etc.)
- Lending positions (Aave, Compound)
- Staking positions
- Yield farming rewards
This DeFi dashboard gives you a consolidated view of your on-chain financial activity without needing to switch to a separate portfolio tracker.
Ethereum L2 Support
Rainbow supports all major Ethereum Layer 2 networks:
The wallet handles network switching cleanly on mobile, which is notoriously difficult to implement well.
WalletConnect Integration
Rainbow supports WalletConnect v2, which lets you connect to desktop dApps by scanning a QR code with your phone. This bridges the gap between mobile wallet usage and desktop DeFi interfaces. Many of the largest DeFi protocols support WalletConnect, making Rainbow usable with essentially any major protocol.
Watch-Only Wallets
You can add any Ethereum address as a watch-only wallet to monitor balances and activity without importing private keys. This is useful for tracking multiple addresses or monitoring positions on addresses stored in cold storage.
Points and Rewards System
Rainbow has a native points and rewards system (Rainbow Points) that rewards users for on-chain activity and wallet usage. Points can have real value in Rainbow’s ecosystem, and the system gamifies responsible on-chain engagement.
Setting Up Rainbow Wallet
iOS Setup
- Download Rainbow Wallet from the App Store (search “Rainbow: Ethereum Wallet”)
- Open the app and tap “Create a new wallet”
- Rainbow generates a 12-word seed phrase — write it down on paper and store it safely offline
- Confirm your seed phrase backup by selecting words in order
- Set up biometric authentication (Face ID or Touch ID)
- Your wallet is ready
Android Setup
The process is identical on Android. Rainbow is available on the Google Play Store. The interface is nearly identical between iOS and Android, which is uncommon for crypto wallets.
Importing an Existing Wallet
If you already have an Ethereum wallet:
- Tap “I already have a wallet”
- Enter your 12 or 24-word seed phrase
- Rainbow imports your wallet and displays your existing assets
You can import multiple wallets and switch between them within the app.
Browser Extension Setup
Rainbow’s browser extension (available for Chrome and Chromium browsers) uses the same seed phrase as your mobile wallet. Install it from the Chrome Web Store, import your existing seed phrase or create a new wallet, and you have Rainbow’s DeFi interface available on desktop as well.
Rainbow vs MetaMask
MetaMask is the most widely used Ethereum wallet, with over 30 million users. Rainbow is the more polished, mobile-first challenger. Here is how they compare:
| Feature | Rainbow | MetaMask |
|---|---|---|
| Mobile app quality | Excellent | Good |
| NFT display | Outstanding | Basic |
| ENS support | First-class | Basic |
| DeFi portfolio view | Yes | Limited |
| Built-in swaps | Yes | Yes |
| Transaction simulation | Limited | No (requires Snap) |
| L2 support | Major Ethereum L2s | 100+ EVM (manual) |
| Browser extension | Yes | Yes |
| Non-EVM chains | No | No |
| Hardware wallet support | Limited | Ledger, Trezor |
| WalletConnect | Yes | Yes |
| User base | Growing | 30M+ |
| Design quality | Premium | Functional |
| Open source | Partial | Yes |
MetaMask wins on raw ecosystem breadth, compatibility, and hardware wallet support. Rainbow wins on user experience, NFT display, and mobile polish.
Rainbow vs Trust Wallet
Trust Wallet is a Binance-backed multi-chain mobile wallet. The comparison reveals a fundamental product philosophy difference:
| Feature | Rainbow | Trust Wallet |
|---|---|---|
| Primary focus | Ethereum ecosystem | 100+ blockchains |
| NFT display | Excellent | Good |
| ENS support | First-class | Basic |
| Supported chains | Ethereum + major L2s | 100+ chains |
| Bitcoin support | No | Yes |
| Solana support | No | Yes |
| BNB Chain support | Limited | Excellent |
| DeFi integration | Ethereum-focused | Multi-chain |
| Design quality | Premium | Standard |
| Company behind it | Independent team | Binance |
If you primarily live in the Ethereum ecosystem and care about design and NFTs, Rainbow is better. If you need to manage assets across many different blockchains, Trust Wallet’s breadth is an advantage.
Supported Assets and Networks
Rainbow’s supported asset list includes:
- All ERC-20 tokens on Ethereum mainnet
- Native tokens on all supported L2 networks
- ERC-721 and ERC-1155 NFTs
- All bridged tokens on Arbitrum, Optimism, Base, Polygon, zkSync, and other supported L2s
Notable limitations:
- No Bitcoin support
- No Solana support
- No Cosmos/IBC support
- Non-EVM chains are not supported
Rainbow’s focus is a deliberate choice. The team believes that building the best possible Ethereum wallet is more valuable than building a mediocre wallet for everything.
Security
Rainbow is a non-custodial wallet with standard self-custody security:
- Your seed phrase is generated locally on your device
- Rainbow servers never have access to your private keys
- Biometric authentication (Face ID, Touch ID, fingerprint) protects app access
- The app is PIN protected as a fallback
Hardware wallet note: Rainbow’s hardware wallet integration is more limited than MetaMask or Rabby. For large ETH holdings, consider a Ledger or Trezor and use Rainbow as a secondary wallet for active use.
What Rainbow does not have: The transaction simulation and pre-sign security checks that Rabby offers. Rainbow shows transaction details clearly, but it does not simulate outcomes before signing in the same way Rabby does. For heavy DeFi users concerned about contract security, Rabby’s additional layer of protection is valuable.
Rainbow for NFT Collectors
NFT collectors represent one of Rainbow’s strongest use cases. The wallet handles the full NFT lifecycle well:
The ENS integration also matters for NFT culture: many collectors use ENS as their primary identity across platforms, and Rainbow makes this seamless.
Rainbow on Base
Base — Coinbase’s Ethereum L2 — has become one of the most active networks in the Ethereum ecosystem, particularly for consumer apps, social tokens, and NFTs. Rainbow has excellent Base support and was one of the early wallets to deeply integrate with Base.
For Base-native users, Rainbow is a natural choice. The wallet handles Base transactions with the same polish as Ethereum mainnet, and Base NFTs display as beautifully as mainnet ones.
