Rabby Wallet Guide 2026: Complete Setup & Features

What Is Rabby?

Rabby is a free, open-source browser extension wallet developed by DeBank, the leading DeFi portfolio tracker. It launched in 2022 as a security-first alternative to MetaMask, quickly gaining traction among DeFi-native users. Key stats:

• Built by DeBank — the team behind the most trusted DeFi portfolio tracker
• EVM-focused — supports all EVM-compatible chains (Ethereum, Polygon, Arbitrum, Optimism, BSC, Base, zkSync, and more)
• Available as browser extension (Chrome, Brave, Edge) and mobile app
• Completely free — no swap fees, no hidden costs
• Open source — fully auditable on GitHub
• Pre-transaction security engine — simulates every transaction before signing
• Growing user base of ~2M active users

Key Features

• Transaction simulation — Every transaction is simulated before you sign, showing exact token movements, gas costs, and contract interactions in plain language
• Security risk alerts — Flags risky contracts, suspicious approvals, and known scam addresses before you interact
• Automatic chain switching — When you visit a dApp on Arbitrum, Rabby automatically switches to Arbitrum. No manual network switching required.
• Multi-chain gas accounts — Deposit ETH once and Rabby manages gas across multiple chains using cross-chain gas features
• Approval management — Built-in dashboard shows all your token approvals across all chains. Revoke with one click.
• Hardware wallet support — Connect Ledger, Trezor, Keystone, and other hardware wallets directly
• No swap fees — Unlike MetaMask (0.875%), Rabby charges zero fees on swaps

Step-by-Step Setup

1. Install Rabby — Download from rabby.io or the Chrome Web Store. Verify the developer is "DeBank Global PTE LTD."
2. Create or import wallet — Create a new wallet with a seed phrase, or import an existing seed from MetaMask or another wallet. Rabby uses the same BIP39 standard.
3. Set password — Create a strong local password to encrypt the wallet on your device.
4. Pin the extension — Click the extensions icon in your browser toolbar and pin Rabby for quick access.
5. Configure security settings — In Settings, review the security rules. Rabby's default security settings are already aggressive — leave them on.
6. Connect hardware wallet (optional) — If you have a Ledger or Trezor, connect it through Settings > Address Management > Hardware Wallet.
7. Start using dApps — Navigate to any EVM dApp. Rabby auto-detects the chain and prompts you with a simulated preview before every action.

Security

• Pre-sign simulation — The killer feature. Before you sign anything, Rabby shows you a human-readable breakdown: which tokens move, how much gas, what the contract does. Malicious transactions are flagged in red.
• Contract risk scoring — Rabby rates every contract you interact with based on age, audit status, and known exploit history.
• Approval dashboard — See every token approval you have ever granted across all EVM chains. Revoke risky or unlimited approvals instantly.
• Open source — Code is publicly auditable. Community and professional auditors review the codebase.
• No data collection — Rabby does not track or monetize your data.
• Watch-only mode — Monitor any address without importing keys, useful for tracking whale wallets.

Fees

• Wallet — Completely free
• Swap fees — Zero. Rabby does not charge any service fee on swaps (routes through 1inch, 0x, Paraswap)
• Network fees — Standard blockchain gas fees apply
• Approval revocation — Small gas fee per revocation transaction
• No premium tier — All features are free for all users

Rabby vs Alternatives

Tips & Tricks

• Import your MetaMask seed — Rabby uses the same BIP39 standard. Import your MetaMask seed phrase and you will see all the same accounts and balances. You can use both wallets simultaneously.
• Use the approval dashboard weekly — Set a habit of reviewing and revoking old token approvals. This is the easiest security win in DeFi.
• Read simulation results carefully — Before signing, always read the simulation output. If it shows unexpected token transfers or approvals, reject the transaction.
• Connect hardware wallet for large holdings — Rabby + Ledger is the best DeFi combo: Rabby's simulation protects you from bad transactions, while Ledger keeps your keys offline.

Rabby is arguably the safest hot wallet for DeFi users. Its transaction simulation alone has prevented countless users from signing malicious transactions. If you interact with DeFi contracts regularly, switching from MetaMask to Rabby is one of the highest-impact security upgrades you can make.
