On paper, Zerion and Rabby look like twins. They’re free, they leave the keys with you, and each comes as a browser extension plus a phone app aimed at DeFi users, the crowd that lends, trades and stakes through on-chain apps. Spend a week with both, though, and they pull in opposite directions.
Go with Zerion when your holdings stretch past Ethereum into Solana or Tron, or when a tidy portfolio screen and a web app matter to you. Rabby’s the better call if you spend nearly all your time on EVM chains, you’d like a wallet that physically stops you signing something dodgy, and you’d rather hand over 0.25% on a swap than 0.67%.
We’ve compared security, everyday handling, network coverage, fees and hardware wallet pairing. All the numbers came straight off Zerion’s and Rabby’s own pages in September 2026.

So What Is Zerion, Exactly?
{{IMG:zerion-vs-rabby-zerion-portfolio.webp}}Zerion, Inc. has been making blockchain portfolio tools since 2017, and its wallet is self-custody. That simply means the private keys, the secret numbers that move your coins, live with you and nobody else. You can run it as a browser extension, as an app on iOS or Android, or in any browser through the web app at app.zerion.io.
It grew out of a portfolio tracker, and you can tell. Tokens, NFTs and DeFi positions all land on a single screen, and it’ll ping you when a wallet you’re following trades or mints something. For the long version, read our Zerion wallet review.
Where Zerion Shines
- You get Solana and Tron next to Ethereum and 35 other fully supported networks, which means one app can carry most portfolios.
- Its web app will follow any wallet address, and you don’t have to install a thing.
- Swaps and bridges are built in, with quotes gathered from several decentralized exchanges.
- There are perpetual futures too, running on Hyperliquid, with leverage of up to 40x across 250+ assets.
- Pay $99 for a year of Premium and you unlock profit and loss tracking plus a CSV export covering 14 networks, which your accountant will appreciate.
And What Is Rabby?
{{IMG:zerion-vs-rabby-rabby-logo.webp}}Rabby’s a self-custodial wallet for Ethereum and the wider EVM family, meaning the networks that run Ethereum-style smart contracts. The audit reports in its repository are filed under DeBank’s name. You’ll find the extension for Chrome, Brave and Edge, and the app on iOS and Android.
Everything about it points at one moment: the second before you sign. It runs each transaction as a simulation first, then spells out in ordinary words what’s leaving your address and what’s coming in. We tested it properly in our Rabby wallet review, and Rabby vs MetaMask lines it up against the wallet most people open first.
Where Rabby Shines
- Before you sign, a simulation tells you exactly how your balances will move.
- Its security engine picks out suspicious spenders and keeps Sign switched off until you press “Ignore All”.
- A swap only asks for the amount it needs, and you can clear out stale approvals in one batch.
- GasAccount covers network fees on every supported chain from a single prepaid pot.
- Eleven hardware wallet brands plug into the extension, and Safe and Cobo Argus handle shared accounts.
Zerion vs Rabby on Security: Who Guards the Sign Button?
Neither one takes custody of anything. The seed phrase sits on your own device, so neither company can dig it out for you or reset a forgotten password. If that trade-off is new to you, our explainer on custodial vs non-custodial wallets covers it.
Where they really split is the signing screen. Rabby plays the transaction out in a simulation and then lets its security engine loose on the result. Spot something like a spender that’s a personal account, or a contract under three days old, and the Sign button goes dead until you click “Ignore All” and own the consequences.
Zerion shows a preview of every transaction before you sign, and it’ll catch phishing websites and apps it already knows about. Scam tokens and NFTs can be reported, and spam tokens hidden. What we couldn’t find anywhere on its security page was a hard stop like Rabby’s grayed-out button, and for us that’s the bigger deal.
{{IMG:zerion-vs-rabby-zerion-token-allowance.webp}}Then come token approvals. An approval (people also call it an allowance) lets a contract spend your tokens, and it keeps working until you take it back. Rabby’s swap requests just what the trade needs and lets you revoke leftovers in bulk.
With Zerion, a swap on an EVM chain takes two signatures. First you approve the token for the Zerion router, then you sign the actual trade. The approval screen spells out the allowance, “Unlimited USDC” in Zerion’s own screenshot, and an “Edit” link lets you shrink it.
The paperwork differs as well. Rabby’s extension is under the MIT license, and you can open SlowMist and Least Authority reports from 2022 through 2025 right in its GitHub repo. Zerion’s extension is GPL-3.0, and Immunefi bounty hunters can earn up to $25,000 for finding new holes.
Oddly, Zerion can’t settle on who audited it. Its GitHub README credits Cure-53, Secfault, SlowMist and Zokyo, yet the security page lists Cube53, Secfault Security, Peckshield and Trail of Bits instead. It also calls its core iOS and Android code open, even though the public mobile repositories haven’t been touched since September 2023, which annoys us more than it probably should.
Both have scars. Attackers hit Rabby’s Swap contract in October 2022, under a month after it went live, and Rabby asked anyone who’d used Swap to revoke those approvals. If you’d never touched Swap, your wallet was fine.
Zerion’s problems came from its own staff and accounts. In June 2023 someone hijacked the company’s Twitter account and posted a fake airdrop link that emptied the wallets of people who signed on it; Zerion said no user private keys were exposed and that it planned to pay victims back. Then in April 2026, a compromised employee device led to about $100,000 leaving internal company hot wallets, with Zerion stating user funds weren’t touched.
Living With Zerion vs Rabby Day to Day
Getting going feels alike. In Zerion’s extension you hit “Create New Wallet”, choose a password, decide on the Ethereum ecosystem, the Solana one or both, and press “Back Up Now” to see your 12-word recovery phrase. Rabby wants “Create a new address”, a password, and then “Back up Seed phrase now”.
Phones differ a little. Zerion locks its app with a 6-digit passcode, while Rabby sticks with a password and lets you add FaceID or Fingerprint. Each will keep an encrypted copy in iCloud or Google Drive if you want, and Zerion insists on a 14-character encryption password for that.
Lost your password? The cure’s basically identical: wipe the wallet and restore it from the seed phrase.
In Zerion’s extension that’s “Need help?” followed by “Clear All Data”, and Rabby just tells you to reset the extension or reinstall the app. No phrase, no rescue, from either company.
Rabby saves you small chores. It flips to the right network by itself when a dapp asks for a different chain, and it scans your address so tokens show up unprompted. Scan a QR code under “Mobile Sync” and Rabby Mobile copies your wallets across from the desktop.
Zerion’s phone app gives you a combined portfolio, but the extension won’t merge several wallets into one view. You can pick Fast, Medium or Custom gas. There’s a Firefox add-on too, though it trails the Chrome build, at version 1.37.1 against 1.42.1 when we looked, while Rabby has no Firefox version at all and says any add-on using its name there is fake.
Ratings lean Zerion’s way. On iOS it scores 4.76 across 4,738 ratings, and Rabby manages 3.49 across 1,269. The Chrome Web Store flips the user count, 900,000 for Rabby against 100,000 for Zerion, but Rabby’s 4.0 still trails Zerion’s 4.7.
Which Chains Zerion and Rabby Actually Cover
Zerion names 38 networks with full support, Solana, Ethereum, Base, Arbitrum and Tron included, and another 21 with lite support. Lite means balances and dapp connections only, with no in-app swaps or bridges and no NFTs on screen. Weirdly, “Zero” still sits on the full list even though that chain has shut down.
Rabby covers any EVM network and has natively integrated 80+, or over 90 if you believe the other help page. Inside the extension, Settings > Integrated Chains shows the real list today. Anything missing can go in through Settings > Add Custom Network, just with a thinner feature set.
Bitcoin, Solana and Tron are off the table for Rabby, and those networks will reject a Rabby address as the recipient. Bitcoin, for what it’s worth, works in neither. Whichever wallet you use, look hard at the wallet address and the network each time you send, because a wrong network or a wrong address loses the funds for good and nobody can undo it.
Hardware wallets are where Rabby runs away with it. Zerion talks to Ledger only, any model over USB on the extension, but just the Nano X over Bluetooth on the phone. Rabby’s extension, meanwhile, takes Ledger, Trezor, GridPlus, OneKey, Keystone, NGRAVE ZERO, BitBox02, CoolWallet, AirGap Vault, imToken and imKey.
Its phone app handles Keystone and OneKey, plus Ledger and Trezor over Bluetooth. Got a Ledger already? We walk through the pairing in our guide to connecting a Ledger to Rabby.
What Zerion and Rabby Really Cost You
Installing costs nothing. Sending and receiving don’t either. You start paying the moment you swap or bridge.
| Charge | Zerion | Rabby |
|---|---|---|
| The wallet itself | Nothing | Nothing |
| Cut on a swap | 0.67% | 0.25% |
| Cut on a bridge | 0.67% | 0.25% |
| Who skips the fee | Gold DNA holders | Anyone on eligible same-chain stablecoin and ETH pairs |
| Paid plan | Premium at $99 a year, bringing the cut to 0.25% | There isn’t one |
Zerion’s cut on swaps and bridges is 0.67% at the time of writing (September 2026). Premium, $99 at the time of writing (September 2026), covers one wallet for 12 months, lowers that cut to 0.25% and won’t renew itself behind your back. For now it only works with EVM wallets, and Solana support is marked coming soon.
Rabby asks 0.25% on swaps and bridges, and the quote you see already includes it. Trade one eligible stablecoin for another, or ETH for tokens like WETH and stETH on the same chain, and you pay nothing at all. Its Swap and Bridge only reach chains its aggregators support, though, so off that map you’ll be using a third-party dapp.
GasAccount itself is fee-free. What you do pay is the network cost of Rabby sending gas to your address, and money you put in through Apple Pay or Google Pay can’t be taken back out.
Perps on Zerion have their own pricing: 0.04%, or 0.02% on Premium, stacked on Hyperliquid’s 0.0432% base fee, and $1 every time you withdraw. For frequent EVM traders, Rabby’s cheaper trade for trade. If you swap a lot on Zerion, we’d run the numbers on Premium, because it drags the swap fee down to where Rabby already sits.
The Good Bits and the Annoying Bits
Zerion: What We Like and What We Don’t
Rabby: What We Like and What We Don’t
So Which One Should You Install?
Holding Solana or Tron alongside your Ethereum tokens? Zerion. Rabby simply won’t take those networks.
Signing contracts on Arbitrum, Base or some other EVM chain most days is a different story, and there we’d pick Rabby without much thought, since the dead Sign button and tight approvals block exactly the kind of slip that empties wallets, and you pay a smaller fee on top.
Keep your keys on a Trezor, Keystone or BitBox02? Rabby again, because Zerion only pairs with Ledger.
Mostly just want to keep an eye on a portfolio? Zerion’s web app and mobile views suit that better, and our roundup of free crypto portfolio tracker apps lists a few alternatives.
Zerion vs Rabby FAQ
Which is safer, Zerion or Rabby?
We’d give it to Rabby, mainly for its signing screen. It simulates every transaction and switches off the Sign button when its security engine spots trouble, whereas Zerion previews transactions and flags known phishing sites without describing any hard block. Neither record is spotless: Rabby’s Swap contract was hit in October 2022, and Zerion’s Twitter account was hijacked in June 2023.
Will Rabby hold my Solana?
No. It’s EVM only, and Rabby says plainly that Bitcoin, Solana and Tron aren’t supported, while Zerion handles both Solana and Tron.
Whose swaps are cheaper?
Rabby’s. You pay 0.25% on swaps and bridges there, and nothing on eligible same-chain stablecoin and ETH pairs. Zerion asks 0.67%, or 0.25% if you buy Premium at $99 a year.
Can one seed phrase run both wallets?
For EVM addresses, yes. Zerion’s help center names Rabby as one of the wallets you can bring over with a recovery phrase or private key, and Rabby imports existing EVM wallets in just the same way. Do it on a machine you trust.
Can I pair a hardware wallet with Zerion or Rabby?
Yes, with limits. Zerion works with Ledger only, and on the phone only with the Nano X. Rabby’s extension takes 11 brands, Ledger, Trezor, Keystone and BitBox02 among them, and its app takes Ledger, Keystone, OneKey and Trezor.
Is the code open source?
For the extensions, yes: GPL-3.0 at Zerion and MIT at Rabby. The mobile side is murkier. Rabby’s app code is public on GitHub but has no license file, and Zerion’s public mobile repositories last changed in September 2023.
Our Verdict: Zerion or Rabby?
If you sign on EVM chains all the time, Rabby takes it. Risky signatures get blocked, swaps only get the approval they need, the cut is 0.25%, and far more hardware wallets pair with it.
Spread across several chains? Then Zerion gets our vote, since Solana and Tron, the web app, perps and that nicer portfolio screen are worth the bigger fee to plenty of people. Nothing stops you keeping both, either, running off one EVM seed phrase.
