Rabby vs Rainbow: DeFi power tool or friendly mobile wallet?

Rabby and Rainbow are both free, open-source, self-custodial wallets for Ethereum and EVM networks. They aim at different people. Rabby, from the DeBank team, is built around DeFi and safety checks. Rainbow started as a design-led iPhone wallet and still puts the mobile app first. Facts were checked on 25 October 2026.

At a glance

Fees

Both wallets are free to use, and sending tokens costs only gas. The difference is in built-in swaps and bridges.

Rabby charges 0.25%, with 0% on stablecoin-to-stablecoin swaps, wrapping ETH and native-to-liquid-staking swaps, and lower rates for trades of $100,000 or more (Rabby source code, October 2026). Its bridge fee is also 0.25%.

Rainbow does not publish a fee schedule on its own site that we could check. Ethereum.org's wallet directory lists Rainbow's swap fee as 0.85%, and Rainbow shows a "Rainbow fee" in each quote before you confirm. On a $1,000 swap that is about $8.50 against $2.50 in Rabby. RNBW token stakers get part of their fees back as staked RNBW (MEXC overview, October 2026), which lowers the effective cost for heavy users. More detail is in Rabby swap fees.

Safety

Both wallets are open source, so outsiders can inspect the code, and both preview transactions. Rainbow's code contains transaction and message simulation for dapp requests. Rabby goes further with a security engine that checks the website, the recipient address, the approval spender and signature contents, and labels each risk before you sign; see Rabby transaction simulation.

Rabby publishes regular third-party audits by SlowMist and Least Authority (most recently August and October 2026). Its history includes the October 2022 exploit of the Rabby Swap contract, in which users who had approved the contract lost about $190,000 to $200,000; keys were not affected. In August 2026 it also fixed a signature bug that needed a 10-minute auto-lock setting and had no known exploitation. See Rabby security history.

We found no reported exploit of Rainbow's wallet software. One October 2026 vendor comparison noted that Walletbeat found no clear public audit or bug bounty for Rainbow; we could not confirm either way, so check Rainbow's own disclosures if this matters to you.

The RNBW token launched on 5 February 2026, and token launches attract fake "claim" sites. The same applies to Rabby, which has no token at all: any Rabby airdrop claim page is a scam.

Features

• Chain coverage: Rabby covers far more EVM networks and lets you add custom ones. Rainbow sticks to Ethereum and its main layer-2s; it tells users not to send tokens on a network the app does not show.
• Mobile experience: Rainbow's apps are its strongest point, with an easy onboarding flow, NFT galleries and ENS names. Rabby's mobile app is aimed more at DeFi than at collecting.
• Desktop: both rely on a browser extension on computers; Rabby's is built around dapp use. Rabby shut down the backend of its old macOS and Windows desktop app on 31 December 2025 (Rabby announcement, December 2025), so that app no longer works; Rabby said a new version is planned, and we could not confirm one is available as of 25 October 2026.
• DeFi tools: Rabby has automatic chain switching, an approvals manager, a Gas Account for paying gas in stablecoins, Safe multisig support and Hyperliquid perps.
• Rewards: Rainbow has the RNBW token, staking with tiered benefits and fee cashback. Rabby has points but no token.
• Hardware: Rabby supports more devices. If you use a Keystone, OneKey, BitBox02 or Lattice, Rabby is the option; see Rabby hardware wallets.

Platforms and day-to-day use

Rabby is strongest at a desk. Its browser extension runs in Chrome, Brave, Edge, Opera and other Chromium browsers. The iOS and Android apps cover sending, swapping, bridging, Gas Account, perps and hardware wallets. Rainbow is strongest on a phone, with its browser extension as a companion for desktop dapps.

A practical difference is how each handles networks. Rabby switches to whatever chain a dapp asks for, and any EVM chain Rabby does not list can be added manually; see how to add a custom network. Rainbow shows only its supported networks and warns users not to send tokens on others, which keeps things simple but means tokens on an unsupported chain will not appear.

Using both, or moving between them

Because both are standard EVM wallets, the same seed phrase gives the same addresses in each. Many people keep Rainbow on their phone for everyday use and Rabby on their computer for DeFi. If both extensions are installed in one browser, dapps may open the wrong one; Rabby has a setting to make itself the default, explained in Rabby not showing in a dapp. To set Rabby up from scratch, follow how to set up Rabby Wallet.

Choose Rabby if… / Choose Rainbow if…

Choose Rabby if

• You use DeFi across many EVM chains, including smaller ones.
• You want lower swap fees and fee-free stablecoin swaps.
• You want a detailed risk check before every signature.
• You work mainly at a computer or use a hardware wallet other than Ledger or Trezor.

Choose Rainbow if

• You mainly use your phone and value a simple, attractive app.
• You stay on Ethereum, Base and the main layer-2s.
• You collect NFTs and use ENS names.
• You want to take part in RNBW staking and rewards.

The two can live side by side: the same seed phrase works in both. Only enter it into apps you downloaded from the official sites (rabby.io for Rabby), never into a website or a "support" chat. Rabby never asks for your seed phrase.
