Core Security Features

01

Pre-sign Simulation

See your balance changes, token approvals, and contract interactions before signing. If something looks dangerous, Rabby warns you clearly.

02

Auto Chain Detection

No more network switching errors. Rabby detects the chain your dApp needs and switches automatically — so you never sign on the wrong network.

03

Risk Alerts

Built-in token and address risk detection flags malicious contracts, honeypots, and phishing addresses right in your transaction flow.

Transparency you can act on

Every signature comes with a plain-language breakdown. No guessing what a contract call will do to your wallet.
