Rabby Wallet:
the transaction-safety tooling every other EVM wallet in this series gets compared against.
We tore apart Rabby, built by the DeBank team specifically for DeFi power users, across the same seven weighted categories as this series; from genuinely the most consistently-praised pre-transaction simulation feature we've found across every wallet we've reviewed, full MIT-licensed open-source code, automatic chain switching, and a swap fee less than a third of MetaMask's, to a real, deliberate EVM-only scope with no native Bitcoin or Solana support, and a mobile app still described as catching up to the more mature browser extension; and landed on a score the marketing page won't show you.
Our take, up front: Rabby is built and maintained since 2021 by the team behind DeBank, the well-known DeFi portfolio tracker, and it shows: this wallet reads like a tool made by people who track DeFi positions professionally, not a general-purpose wallet with security features bolted on later. Real, genuinely non-custodial: keys are generated and stored locally on-device, never transmitted to DeBank's servers, with no account signup or KYC required. Real, fully open-source under the MIT license, with public GitHub repositories covering the extension, mobile, and desktop apps, transparency comparable to or exceeding what we found reviewing MetaMask. Here's the real, consistent theme across literally every source we found: pre-transaction simulation shows the exact balance changes, token approvals, and risk flags a transaction will cause before you sign, independently and repeatedly described as "the defense layer a hardware wallet alone does not give you." Real, genuinely distinctive automatic chain switching removes the friction of manually configuring networks, and a real, built-in approval manager offers one-click revocation of dangerous token approvals. Real, precisely quantified, notably lower swap fee than MetaMask: 0.25% versus 0.875%, and entirely avoidable if you route swaps through a separate DEX. What we can't set aside: this is deliberately, entirely EVM-only, with no native Bitcoin or Solana support at all, "everything stops at the EVM boundary," as one detailed source put it. The mobile app, launched in late 2025, brings the same simulation security to phones but is still described as catching up to the more mature browser extension. We weighted all of it below.
Real, genuinely non-custodial architecture: keys are generated and stored locally on-device, never transmitted to DeBank's servers, with no account signup or KYC required. Real, fully open-source under the MIT license, with public GitHub repositories covering the extension, mobile, and desktop apps, genuinely thorough transparency comparable to or exceeding what we found reviewing MetaMask. Real, the most consistently and repeatedly praised feature across every source we found: pre-transaction simulation shows the exact balance changes, token approvals, and risk flags a transaction will cause before you sign, independently described across multiple sources as "the defense layer a hardware wallet alone does not give you." Real, built-in approval manager offers one-click revocation of dangerous token approvals across chains. Real, repeat security audits are referenced across sources, though we couldn't identify a single, specifically named independent auditor. We found no disclosed vulnerability or security incident specific to Rabby in our research. At least one source, itself a hardware wallet company, recommends pairing Rabby with a hardware wallet for large holdings, consistent, sensible advice we've echoed throughout this series.
Pros
- Fully open-source under MIT, covering extension, mobile, and desktop code
- Most consistently-praised pre-transaction simulation feature we've found in this series
- Built-in one-click approval revocation across chains
- No disclosed vulnerability found in our research
Cons
- No single, specifically named independent auditor found in our research
Real, genuinely broad EVM-specific coverage: 90 to 100-plus EVM-compatible networks without requiring manual RPC configuration for most popular chains. Real, deliberate scope limitation: this is EVM-only by design, with no native Bitcoin or Solana support, a narrower footprint than MetaMask's expanding non-EVM coverage specifically.
Pros
- 90-100+ EVM-compatible networks without manual RPC configuration
- Actively, regularly expanding network list
Cons
- EVM-only by design; no native Bitcoin or Solana support
Real, genuinely distinctive automatic chain switching removes the friction of manually configuring networks. Real, unified multi-chain portfolio view and DeBank-powered analytics bring genuine dashboard-level visibility most wallets don't offer. Real, consistently and repeatedly described as a smoother, clearer signing experience than MetaMask specifically. Real, low-friction MetaMask import feature carries over existing addresses.
Pros
- Automatic chain switching with no manual RPC configuration
- Unified, DeBank-powered multi-chain portfolio dashboard
- Low-friction MetaMask import for existing users
Cons
- None significant found in our research
Real, browser extension (the original, most mature surface) plus a real, genuinely newer mobile app that launched in late 2025, bringing the same simulation security to phone use; at least one source describes the mobile experience as still "catching up" to the extension. No independently-documented reliability or uptime complaints found in our research. Real, honest limitation: no dedicated native desktop application beyond the browser extension itself.
Pros
- Browser extension, mobile, and desktop app all available
- No documented reliability or uptime complaints found
Cons
- Mobile app still described as catching up to the more mature extension
Rabby is built and maintained by the DeBank team, a real, established company known for its DeFi portfolio tracking platform, with Rabby itself operating since 2021. We found no disclosed vulnerability or security incident specific to Rabby in our research. Real, repeat security audits are referenced across multiple sources, though without a single, specifically named independent auditor identified in our research.
Pros
- Established team behind a well-known DeFi portfolio platform
- No disclosed vulnerability found in our research
Cons
- No specifically named independent auditor found in our research
The wallet itself is free to download and use. Real, precisely quantified, and notably lower swap fee than we found reviewing MetaMask: 0.25% versus MetaMask's 0.875%, avoidable entirely by routing swaps directly through a separate DEX or aggregator. All other costs are standard network gas paid to the blockchain, not to Rabby.
Pros
- 0.25% swap fee, less than a third of MetaMask's 0.875%
- Swap fee entirely avoidable by routing through a separate DEX
Cons
- None significant found in our research
Real, distinctive pre-transaction simulation and built-in approval manager are genuinely advanced, real extras that go well beyond core wallet functionality. Real, DeBank-powered portfolio analytics bring dashboard-level visibility. Real, points/rewards system exists, though no confirmed native token has launched as of our research; we'd treat any airdrop expectation with the same caution we've applied elsewhere in this series.
Pros
- Genuinely advanced pre-transaction simulation and approval management
- DeBank-powered dashboard-level portfolio analytics
Cons
- No confirmed native token; treat airdrop speculation with caution
Download only through Rabby's official site or verified app stores.
Fake extensions mimicking popular DeFi wallets are a real, documented threat. Downloading direct or through an official, verified listing is the only way to be confident you're not installing a malicious clone.
The highest score in this series so far, earned specifically by taking signing safety seriously.
What separates Rabby from the rest of this series isn't a longer feature list, it's that one specific thing, showing you exactly what a transaction will do before you approve it, is executed more thoroughly here than anywhere else we've reviewed. That's not marketing language; every independent source we found, without exception, converges on the same point. Pair that with fully open, publicly auditable code and a swap fee a third of MetaMask's, and the case is genuinely strong. The honest limit is scope: this stops firmly at the EVM boundary, and if your holdings live on Bitcoin or Solana, none of this helps you directly.
The scorecard above is deliberately general. Whether Rabby is right for you depends heavily on which of these you already are.
The active DeFi user who signs complex, multi-step EVM transactions regularly
Pre-transaction simulation is genuinely the most thorough safety net we've found in this series for exactly this use case.
The MetaMask user who wants the same ecosystem access with better signing safety
The low-friction import feature and consistently-praised UX improvements make switching genuinely painless.
The cost-conscious trader who swaps frequently and wants the lowest fee available
At 0.25%, and avoidable entirely by routing through a separate DEX, this is real, genuine savings over time.
Anyone holding Bitcoin, Solana, or other non-EVM assets who needs single-wallet coverage
This is deliberately, entirely EVM-only; you'll need a separate wallet for anything outside that scope.
The scorecard covers the headline judgment calls. These four tables cover the specifics we didn't want to bury in prose; what pre-transaction simulation actually shows, Rabby vs. MetaMask head to head, swap fees compared across this series, and how ten wallets now compare on custody model.
What pre-transaction simulation actually shows
| Shown before you sign | Why it matters |
|---|---|
| Exact balance changes | Confirms precisely what leaves and enters your wallet, not just what you intended |
| Token approvals being granted | Reveals unlimited or hidden approvals before they're locked in |
| Risk flags on the contract | Surfaces known scam patterns, honeypots, and malicious contract behavior |
| Gas cost | Shown in plain terms alongside the rest, not as a separate step |
This is real, meaningfully more thorough than the transaction-scanning features we found reviewing MetaMask, Zengo, Trust Wallet, and Phantom, all of which offer some form of pre-sign warning, but none as consistently praised for depth as this one.
Rabby vs. MetaMask, head to head
| Rabby | MetaMask | |
|---|---|---|
| Chain scope | EVM-only | EVM plus expanding non-EVM (Bitcoin, Solana) |
| Swap fee | 0.25% | 0.875% |
| Chain switching | Automatic | Manual network configuration for some chains |
| Transaction preview depth | Full simulation with exact balance changes | Contract-level scanning and warnings |
| Ecosystem reach | Smaller, DeFi-power-user focused | The broader industry default |
Every source we found makes this same comparison; the consistent conclusion is that Rabby leads on EVM signing safety and cost, while MetaMask wins on broader reach and non-EVM coverage.
Swap fees, compared across this series
| Wallet | Swap fee |
|---|---|
| Rabby | 0.25%, avoidable |
| MetaMask | 0.875% |
| Exodus | 1-4% |
| Coinbase Wallet | 0.5-1% |
Rabby's fee is genuinely the lowest, most transparently structured swap cost we've found across this entire series so far.
Ten custody models, compared
| Exodus | MetaMask | Zengo | Trust Wallet | Phantom | Best Wallet | Sparrow | BlueWallet | Coinbase Wallet | Rabby | |
|---|---|---|---|---|---|---|---|---|---|---|
| Custody model | Seed | Seed | MPC | Seed | Seed | Unclear | Seed | Seed/custodial | Seed+passkey | Seed |
| Scope | Multi-chain | Multi-chain | Multi-chain | Multi-chain | Multi-chain | Multi-chain | BTC-only | BTC-only | Multi-chain | EVM-only |
| Code | Closed | Open | Partial | Partial | Closed | Unclear | Open | Open | Unclear | Open |
Rabby joins MetaMask, Sparrow, and BlueWallet as the fourth fully open-source wallet in this series.
We don't just want to hand you our number; we want to show you how it sits next to what other review desks and comparison sites have published. This includes one real, specifically-cited score. We've excluded one source entirely: it closed its otherwise-detailed review with an unrelated promotional plug for a separate "no-KYC instant swap platform," a red flag for content quality we didn't want to weight into our comparison.
Our score lands modestly below the aggregated industry average; several sources write with genuine enthusiasm bordering on promotional tone specifically because Rabby's core audience (active DeFi "farmers") overlaps heavily with the sites covering it.
| Source | Score | Type |
|---|
Scores compiled by our editorial team from publicly available reviews as of August 2026. "Editorial estimate" means the outlet didn't publish a single numeric score, so we converted their published verdict and sentiment into a comparable 100-point figure. Verify current figures directly with each source before citing them elsewhere.
For EVM signing safety specifically, every source we found agrees Rabby leads, largely due to its pre-transaction simulation. MetaMask remains broader in reach and now supports non-EVM chains Rabby doesn't cover at all.
Before you approve a transaction, Rabby shows the exact balance changes, token approvals being granted, and risk flags on the contract, in plain terms rather than raw hex. It's the most consistently-praised feature across every source we found.
No. Rabby is EVM-only by deliberate design, with no native Bitcoin or Solana support at all.
The wallet is free. Its built-in swap feature charges 0.25%, less than a third of MetaMask's 0.875%, and it's entirely avoidable if you route swaps directly through a separate DEX.
Yes, fully open-source under the MIT license, with public GitHub repositories covering the extension, mobile, and desktop apps.
Yes, Rabby supports a low-friction import that reads existing addresses, making it easy to switch or run both wallets alongside each other.
Not confirmed as of our research. A points system exists and has fueled airdrop speculation, but we'd treat any expectation of a token launch as speculation, consistent with how we've handled similar situations elsewhere in this series.
At least one source recommends pairing Rabby with a hardware wallet for large holdings, sensible, standard advice consistent with how we'd frame any hot wallet in this series.

Exodus – Hot Wallet Review
Score: 70/100. Polished, beginner-friendly self-custody, but closed-source code and an optional cloud backup for your seed phrase are real trade-offs.

MetaMask – Hot Wallet Review
Score: 74/100. The DeFi default for real reasons: open code, broad EVM reach, but no auto-sync and a real fight over non-EVM support.

Zengo – Hot Wallet Review
Score: 71/100. No seed phrase at all via MPC, but that just relocates trust to Zengo's own servers instead of removing it.

Trust Wallet – Hot Wallet Review
Score: 70/100. Broadest chain coverage in the series, sitting on a browser extension with three real, documented security incidents since 2023.
