Rainbow

Rainbow showed up in 2019 when most crypto wallets looked like they were designed by developers who had never used a smartphone app before. The New York-based team had a different idea: what if a wallet could actually be pleasant to use? I remember first installing Rainbow in early 2023 and being genuinely surprised. The animations feel polished, not overdone. Navigation makes sense without reading a manual. And my NFTs - suddenly they looked like a curated collection instead of random thumbnails crammed into a grid. The Rainbow Router is one of those features you forget exists because it just works. It checks prices across different DEXs and routes your swap to get you the best rate. No toggling between tabs or manually comparing Uniswap to SushiSwap. I have probably saved a few hundred dollars over the past two years just from better swap execution.

Security is where Rainbow either earns or loses my trust, and I have spent a good amount of time testing how well it actually protects crypto assets. You can stack all the features you want into a wallet, but if someone can drain your funds because of a security flaw, none of that matters. Here is my honest breakdown of every security layer Rainbow provides.

Rainbow relies on a traditional seed phrase for backup. During initial setup, you get a recovery phrase that acts as the master key to your funds. Lose this phrase and your crypto is gone permanently - there is no customer support hotline to call. I store mine on a steel backup plate in a fireproof safe. Paper backups work, but they are vulnerable to water damage and fire. The critical rule: never save your seed phrase digitally. Not in your notes app, not in a screenshot, not anywhere connected to the internet. This is how most people lose their crypto.

The codebase behind Rainbow is open source, and that is a meaningful trust signal. Open source means independent security researchers can examine every line of code on GitHub. Bugs get found faster because thousands of developers can review the code rather than just an internal team. The practical benefit is transparency - you do not have to take the developer's word for it that your keys are handled safely. I always give extra points to wallets that open their code to public scrutiny.

For day-to-day device security, Rainbow offers biometric authentication (fingerprint or face recognition) and PIN code protection. These layers prevent someone who picks up your unlocked phone or steals your device from immediately accessing your funds. During my testing, the authentication process added maybe one second to each interaction - barely noticeable but meaningful for protection. I recommend enabling every available security option, even if it adds slight friction.

As of early 2026, Rainbow has maintained a clean security record with no known breaches or exploits. In an industry where exchange hacks and wallet vulnerabilities make headlines regularly, a proven track record matters. The combination of active security measures and real-world reliability gives me reasonable confidence in using Rainbow for meaningful amounts.

The range of supported blockchains determines what you can actually do with Rainbow, and this is where many wallets differ dramatically. Some try to support everything, others focus on a specific ecosystem. Here is exactly what Rainbow covers.

Rainbow currently supports Ethereum, Polygon, Arbitrum, Optimism, Base, Zora, BNB Chain and Avalanche. That gives you access to roughly 20 native coins and 10000+ tokens across these networks. Whether that is enough depends entirely on what you hold and what you plan to do.

Supporting 8 networks makes Rainbow one of the more versatile multi-chain wallets available. You can manage assets across different ecosystems without juggling multiple wallet apps. During my testing, switching between chains was straightforward. Token detection worked well on major chains, though I occasionally needed to add custom tokens on smaller networks.

Supported chains at a glance:

NFT support is included, which means you can view, send, and receive NFTs directly within Rainbow. The NFT gallery shows your collection with previews, and sending NFTs works just like sending tokens. If you are active in the NFT space, having this built into your primary wallet saves you from needing a separate app.

One thing I always check is how well a wallet handles new token additions. With Rainbow, recognized tokens on supported chains appear automatically in your balance. For lesser-known tokens, you can add them manually using the contract address. The process is painless, though it would be nice if the token database was more comprehensive out of the box.

Cross-chain considerations are increasingly important in 2026. If you hold assets across multiple ecosystems, you need a wallet that either supports all of them or plays well with bridges. Rainbow's chain coverage dictates your options here. For assets on unsupported chains, you will need a secondary wallet, which adds complexity to your setup but is a reality for most multi-chain users. The ideal solution is to pick a primary wallet for your main holdings and use chain-specific wallets for smaller positions on niche networks.

Setting up Rainbow is something I have done multiple times across different devices, so I can walk you through exactly what to expect. The wallet is available on iOS, Android and browser extension (Chrome, Firefox, Brave), and the setup process is similar across all of them.

Step 1: Download the app. Get Rainbow from the official App Store or Google Play Store. Make sure you are downloading the legitimate app - check the developer name and review count. Fake wallet apps are a real threat.

Step 2: Create a new wallet. Open the app and select 'Create New Wallet'. The app will walk you through the initial setup, which typically takes 2-3 minutes.

Step 3: Secure your backup. You will be asked to back up your wallet. Follow the instructions carefully and store your backup information securely offline.

Step 4: Enable security features. Turn on biometric authentication, set a strong PIN, and enable any additional security options the wallet offers. Do this before sending any crypto to the wallet.

Step 5: Fund your wallet. You can receive crypto by sharing your wallet address or QR code. Double-check the address on your first transaction - send a small test amount before transferring larger sums.

A nice bonus: Rainbow supports buying crypto with fiat currency directly in the app through Ratio and Coinbase Pay. This means you can go from zero to funded without needing to use an external exchange first. Fees for fiat purchases are typically 1-3% depending on the provider and payment method, which is standard for this kind of service.

The entire setup process took me about 5-10 minutes on my first try. If you have set up a crypto wallet before, you will breeze through it even faster. The important thing is to not rush the backup step - that is the one part where a mistake can cost you money later.

DeFi access is becoming a baseline expectation for modern wallets, and Rainbow has its own approach to decentralized finance features. Here is what you can actually do from within the wallet without needing external tools.

Token swaps are handled through Rainbow Router (best price aggregator). You can swap tokens directly inside Rainbow without visiting a separate DEX. In my testing, the swap interface was clean and showed estimated fees upfront. Slippage tolerance is adjustable, which matters for larger trades or volatile tokens. The swap rates were competitive with what I got on standalone DEX interfaces - not always the absolute best price, but close enough that the convenience is worth it.

dApp access is built in, letting you interact with decentralized applications directly. This includes DEXs, lending protocols, yield farming platforms, and more. The built-in dApp browser handles the connection seamlessly - you do not need to manually copy addresses or switch between apps.

WalletConnect support means you can connect Rainbow to virtually any dApp that supports the protocol. Scan the QR code, approve the connection, and you are in. I use this regularly for protocols that do not have a native integration with Rainbow, and the experience is smooth. Transaction signing happens in the wallet with clear details about what you are approving.

The portfolio tracker gives you a consolidated view of your holdings, showing total value, individual token balances, and price changes. It is not as detailed as a dedicated portfolio app, but it handles the basics well. For most users, having this built into the wallet eliminates the need for a separate tracking tool.

Fiat on-ramps let you buy crypto with a credit card, debit card, or bank transfer without leaving the wallet. The fees are typical for this kind of service (1-3%), and the purchased tokens land directly in your wallet. This is convenient for new users who do not have crypto yet and want a simple path from fiat to tokens.

DeFi security considerations are worth noting. Every time you interact with a smart contract through Rainbow, you are granting that contract certain permissions. Always review what you are approving before signing transactions. Unlimited token approvals are convenient but give the contract access to your entire token balance. Where possible, set specific spending limits for each approval. Some wallets make this easy to manage, others require manual effort.

The DeFi experience in Rainbow is practical rather than flashy. It covers the features that most users need on a daily basis without overwhelming you with options. Power users who want every possible DeFi integration might want a specialized DeFi wallet, but for the average crypto holder, this covers the important bases. The key advantage is having everything in one place - you do not need to jump between multiple apps to manage your DeFi positions.

Understanding the real cost of using Rainbow requires looking beyond the sticker price. Some wallets are free to download but expensive to use, while others charge upfront but save you money on transactions. Here is the full cost picture.

Rainbow is free to download and use. There is no subscription fee, no monthly charge, and no premium tier you need to unlock. The wallet makes money through other means - typically a small spread on in-app swaps or partnerships with fiat on-ramp providers.

Swap fees are where most wallets generate revenue, and Rainbow is no exception. When you swap tokens inside the wallet, there is typically a small fee built into the exchange rate on top of the network gas fees. This markup is usually 0.5-1%, which is reasonable for the convenience. If you want the absolute best rates, you can always connect to a DEX directly, but for everyday swaps, the built-in option saves time.

Network fees (gas) are unavoidable with any wallet - these go to the blockchain validators, not to Rainbow. Gas costs vary wildly depending on the network and current congestion. Ethereum mainnet transactions can cost anywhere from a dollar to over fifty dollars during peak times. Layer 2 networks like Polygon, Arbitrum, and Optimism typically cost pennies. If Rainbow supports L2 chains, using them for everyday transactions is the smart move financially.

Hidden costs to watch for:

1. Token approval transactions cost gas even though they do not move funds
2. Failed transactions still consume gas - double-check details before confirming
3. Bridging between chains incurs fees from both the bridge protocol and gas on two networks
4. Some in-app features like premium analytics or advanced charts might have separate costs

Compared to using a centralized exchange, Rainbow trading costs are typically higher for frequent traders because DEX swap fees plus gas exceed the 0.1% fee you would pay on a major exchange. But the trade-off is that you maintain full custody of your assets at all times. For buy-and-hold users who swap occasionally, the cost difference is negligible, and the security benefit of self-custody is worth the premium.

Annual cost estimate for a typical user: If you make about 10 transactions per month with Rainbow, your total annual cost in fees (gas + swap spreads) would be somewhere between 50 and 300 dollars depending on the networks you use and the size of your transactions. Ethereum mainnet pushes you toward the higher end while Layer 2 networks keep costs minimal. Factoring this into your wallet choice makes sense if you are cost-conscious.

Not every wallet is right for every person, and Rainbow is no exception. After testing it extensively, I have a clear picture of who will love it and who should look elsewhere.

Rainbow is a strong choice for:

1. NFT collectors and creators
2. Users who value beautiful design
3. Ethereum ecosystem enthusiasts
4. Those wanting easy multi-chain bridging

Rainbow is probably not ideal for:

1. Bitcoin holders
2. Non-English speakers
3. Hardware wallet users
4. Enterprise/institutional users

As a mobile wallet, Rainbow is designed for accessibility and daily use. It works well for people who want quick access to their funds and interact with crypto regularly. For very large holdings, consider pairing it with a hardware wallet - keep your spending money in Rainbow and your savings in cold storage.

With an overall rating of 8.6/10 in my testing, Rainbow is a solid choice within its target market. It is not trying to be everything for everyone, and that focused approach means it does what it does well. Match your needs to its strengths, and you will have a good experience.

My general recommendation: try Rainbow with a small amount first. Spend a week or two getting familiar with the interface, testing the features that matter to you, and seeing how it fits into your workflow. Crypto wallets are personal tools - what works perfectly for me might not click for you, and the only way to know is to actually use it.

Switching from another wallet? Moving your crypto to Rainbow is straightforward - just send assets to your new wallet address. But think carefully before moving everything at once. Import one chain or a small amount first, confirm everything works as expected, and then gradually move the rest. I have seen too many people rush the migration process and make costly mistakes, like sending tokens on the wrong network. Take it slow, double-check every address, and use test transactions for anything significant. The few minutes of extra caution can save you thousands.

Customer support is often overlooked when choosing a wallet, but it matters the moment something goes wrong. A stuck transaction, a display glitch, or an authentication problem can become stressful fast when your money is on the line. Here is what to expect from Rainbow's support options.

Most self-custody wallets, Rainbow included, operate with leaner support teams than centralized exchanges. This is partly by design - a self-custody wallet handles fewer things server-side, so there are fewer things that can go wrong on their end. But when you do need help, the available channels matter.

Typical support channels:

1. Documentation and help center - the first place to check for common issues
2. Email support - for specific account or technical problems
3. Community forums and Discord - peer help from other users
4. Social media - sometimes the fastest way to get attention on an issue
5. In-app help - guides and FAQs accessible within the wallet itself

In my experience, response times for email support average 24-48 hours for most wallet providers. Community channels like Discord or Telegram can provide faster answers for common questions since other users are often willing to help. However, be extremely cautious in community channels - scammers frequently impersonate support staff and try to get you to share your seed phrase or connect your wallet to malicious sites. Legitimate support will never ask for your private keys or seed phrase.

Troubleshooting tips before contacting support:

1. Check the help center for your specific issue
2. Clear the app cache or reinstall (your funds are safe on-chain)
3. Try connecting on a different network (WiFi vs mobile data)
4. Check the project's status page for known outages
5. Search community forums - someone has likely faced the same issue
