Almost every wallet asks you to approve a transaction described in terms only a developer could evaluate. Rabby simulates the transaction against current chain state and tells you, in plain terms, which tokens will leave your wallet and which will arrive. If a signature would grant unlimited spending permission to an unknown contract, you see that before you sign, not afterwards.
What else it does well
Automatic network switching, so you never sign on the wrong chain. Per-dapp risk scoring based on contract age, audit status and reported incidents. A built-in approval manager that shows every standing permission you have granted and revokes them in a click. Hardware wallet support across all major devices. All of it open source and regularly audited.
The limitations
EVM chains only — no Bitcoin, no Solana, no Cosmos. It is built by DeBank, an analytics company, which means portfolio data flows to their backend when you use those features. Neither is disqualifying, and both are worth knowing.
Practical advice
Use Rabby as your daily EVM wallet with a hardware wallet holding the keys for anything substantial. The simulation still works with hardware signing, so you get both readable transactions and offline key storage. Review your approvals monthly — Rabby makes that a two-minute task rather than a chore.
Who should use it
Every EVM user. If you currently use MetaMask out of habit, Rabby imports the same seed and provides strictly more safety information for the same actions.
