Before you use it
- Because Rabby is a self-custodial tool, loss of the local device or encrypted storage files without a secured physical backup of the seed phrase can lead to permanent loss of funds, with no centralized password-reset mechanism available.
- Users must strictly use official links (rabby.io or official browser store listings) to avoid malicious copycat extensions or phishing websites designed to steal private keys.
- While Rabby features pre-transaction risk scans, security tools cannot entirely prevent interaction with malicious or volatile smart contracts (such as honeypots or high-risk tokens often encountered in speculative trading).
