What is Rainbow Wallet and Why Do Users Love It?
Cryptocurrency wallets often prioritize function over form. They work well enough, but the interfaces feel clunky and intimidating to newcomers. Rainbow Wallet takes a different approach by focusing on design and user experience without sacrificing security or functionality.
Rainbow is a non-custodial cryptocurrency wallet built specifically for the Ethereum ecosystem. The project positions itself as a "fun, powerful, and secure" gateway to the decentralized web. Users maintain exclusive control over their private keys, which means Rainbow never has access to their funds. The wallet supports Ethereum mainnet and major Layer 2 solutions like Arbitrum, Optimism, and Base.

The project is available in two formats. Rainbow Mobile is a feature-rich app for iOS and Android designed for "onchain on-the-go" use. Rainbow Extension is a browser-based version that works with Chrome, Firefox, Safari, and Edge. The extension features a keyboard-first design with a ⌘K command system that lets power users navigate quickly without touching their mouse.
Alexis Ohanian, co-founder of Reddit and lead investor through Seven Seven Six, has publicly praised Rainbow as the "best designed" wallet currently available in the market. This endorsement from a prominent tech figure reflects the project's emphasis on making crypto accessible through thoughtful design.
Who Built Rainbow Wallet?
Rainbow was founded by a team with backgrounds in engineering and design. Their focus on making "crypto in color" distinguishes the project from more utilitarian competitors.
Founding Team
The core team combines technical expertise with design sensibility:
- Christian Baroni: CEO and Co-Founder who leads overall strategy and vision
- Michael Demarais: Engineer and Co-Founder responsible for technical architecture
- Jin Chung: Co-Founder contributing to product development
- Jeremy Goldberg: Designer who shapes the visual experience
The founding team's composition reflects Rainbow's priorities. Having a dedicated designer as a core team member signals that user experience is not an afterthought but a fundamental part of the product strategy.
Rainbow Wallet Funding: $19.5 Million Raised Across 3 Rounds
Rainbow has raised a total of $19.5 million across three funding rounds. The investor roster includes prominent venture capital firms and celebrity backers who recognized the potential for a design-focused wallet.
| Date | Round | Amount Raised | Lead Investor |
| January 2020 | Seed Round | $1.5 million | Undisclosed |
| May 2020 | Seed Round | Undisclosed | Digital Currency Group (DCG) |
| October 2021 | Series A | $18 million | Seven Seven Six (Alexis Ohanian) |
Notable Investors and Backers
The Series A round in October 2021 brought significant capital and high-profile supporters. Seven Seven Six, Alexis Ohanian's venture fund, led the round with an $18 million investment. The funding was directed toward expanding UX capabilities and building swap features.
Other notable investors include:
- Y Combinator — Premier startup accelerator
- Digital Currency Group — Crypto-focused investment firm
- 6th Man Ventures — Sports and tech venture fund
- Thirty Five Ventures — Kevin Durant's investment vehicle
The participation of Kevin Durant's fund reflects a broader trend of celebrity interest in crypto infrastructure. The combination of traditional venture capital, crypto-native investors, and celebrity backing provided Rainbow with both capital and visibility.
Rainbow Wallet Features: What Makes It Different?
Rainbow combines standard wallet functionality with unique features designed to enhance the user experience. The wallet focuses on making complex crypto operations feel simple and intuitive.
Multi-Chain and Layer 2 Support
While Rainbow is primarily focused on Ethereum, it supports major Layer 2 solutions to reduce transaction fees and speed up confirmation times. Users can interact with Arbitrum, Optimism, Base, and other L2 networks directly from the wallet interface.
The wallet also allows custom RPC settings, which means users can add any EVM-compatible chain manually. This flexibility ensures Rainbow can grow with the ecosystem as new chains emerge.

Built-In Swaps and Bridging
Rainbow integrates decentralized exchange aggregators like Uniswap to find the best rates for users. Token swaps happen directly within the app without requiring users to visit external DEX interfaces. The aggregation feature compares rates across multiple liquidity sources and routes trades for optimal pricing.
Bridging between chains is also handled natively. Users can move assets between Ethereum mainnet and Layer 2 networks without leaving the Rainbow interface.
NFT Management and Showcases
Rainbow is regarded as a premier platform for digital collectibles. The wallet supports all media formats for NFTs, including images, videos, and audio files. Users can view and accept marketplace offers directly within the app.
The "showcases" feature allows users to curate and display their NFT collections. This social element transforms the wallet from a purely functional tool into a way to express identity and taste through digital art.
ENS Integration
Ethereum Name Service (ENS) integration allows users to replace complex alphanumeric addresses with human-readable .eth names. Instead of sending funds to a 42-character hexadecimal string, users can send to names like "alice.eth" directly within the wallet interface.
Impersonation Mode
A unique feature called Impersonation Mode allows users to view any wallet address in a read-only format. This functionality helps users track portfolios, monitor whale addresses, or study how successful traders manage their holdings. No transactions can be made in this mode, but it provides valuable visibility into any public address.
Rainbow Wallet vs. MetaMask: How They Compare
Rainbow's Strengths
Rainbow excels in user experience and visual design. The NFT showcases, intuitive swap interface, and polished animations create an experience that feels premium. For users who primarily interact with Ethereum and its L2 ecosystem, Rainbow provides everything they need in an aesthetically pleasing package.
Rainbow's Limitations
The exclusive focus on Ethereum and EVM-compatible chains is a limitation for users with diverse portfolios. If you hold Bitcoin, Solana, or other non-EVM assets, you need additional wallets to manage those holdings. This fragmentation can lead to frustration or management errors for users who prefer a single unified interface.
How Rainbow Wallet Handles Security
Rainbow employs a multi-layered security architecture that protects users while maintaining ease of use. The wallet balances convenience with strong security practices.
Self-Custody Foundation
Rainbow is a fully self-custodial wallet. Users own their private keys exclusively, and Rainbow never has access to them. This means users are responsible for their own security, but it also means no company can freeze, seize, or lose their funds.
Open Source Code
The Rainbow codebase is available on GitHub for public scrutiny. Open source development allows security researchers and developers to identify vulnerabilities before they can be exploited. This transparency builds trust and enables the community to verify that the wallet functions as advertised.
Hardware Wallet Integration
Rainbow supports hardware wallet integration for users who want maximum security:
- Ledger Nano X: Bluetooth-enabled hardware wallet support
- Trezor: USB-connected hardware wallet support
Hardware integration allows users to sign transactions physically, keeping private keys isolated from internet-connected devices. This approach protects against malware and remote attacks.
Flashbots Protection
Rainbow includes Flashbots protection to guard users against MEV (Maximum Extractable Value) exploitation. When users make swaps, they can be vulnerable to "sandwich attacks" where bots front-run and back-run their transactions to extract value. Flashbots protection routes transactions through private mempools that hide them from predatory bots.
Rainbow Wallet's Recent Updates and Community Initiatives
Rainbow has continued developing new features and building community engagement since the Series A funding round.
Rainbow Wallet: Product Development
Following the $18 million Series A, Rainbow focused on several key areas:
- Swap Aggregators: Improved routing and rate comparison across DEX platforms
- ENS Profile Integration: Deeper integration with Ethereum Name Service for identity features
- Rainbow Extension: Launch of the browser extension with ⌘K command functionality
- Expanded L2 Support: Added support for additional Layer 2 networks

Rainbow Community NFT Drops
The project has launched exclusive NFT drops to build community loyalty. Notable releases include the "Rainbow Poolboy" collection and "Rainbow World" interactive experiences. These drops reward active community members and create shared identity among Rainbow users.
Customer Support Improvements
There has been some discrepancy in user resources regarding customer support. Earlier reviews noted a lack of live customer support options. However, official sources now highlight a 24/7 global support team with documented response times as fast as four minutes. This improvement addresses a previous pain point for users who needed assistance.

What Rainbow Wallet Means for Ethereum Users
Rainbow represents a specific philosophy about what crypto wallets should be. The project prioritizes design and user experience in a space where these qualities are often overlooked. For users who live primarily within the Ethereum ecosystem, Rainbow offers one of the most polished experiences available.
The $19.5 million in funding from investors like Y Combinator, Digital Currency Group, and Alexis Ohanian's Seven Seven Six validates this approach. The celebrity backing from Kevin Durant adds visibility beyond traditional crypto audiences.
The EVM-only limitation remains a real constraint for users with diverse portfolios. However, for those who focus on Ethereum, its Layer 2 networks, and the growing ecosystem of EVM-compatible chains, Rainbow delivers a premium experience. The combination of built-in swaps, NFT showcases, ENS integration, and hardware wallet support covers most use cases while maintaining the design quality that sets Rainbow apart from its competitors.
