How to Connect Rabby Wallet to a dApp Without Approving Unnecessary Permissions?

Understanding Rabby’s Permission Model

1. Rabby wallet does not auto-grant permissions upon connection — every access request must be explicitly confirmed by the user.

2. When a dApp initiates a connection, Rabby displays a modal showing the requesting domain, requested account scope, and network context (e.g., Ethereum Mainnet or BSC Testnet).

3. The wallet distinguishes between read-only actions (like fetching balance) and state-altering operations (like signing transactions), each requiring separate consent.

4. Permissions are session-bound: they expire when the browser tab is closed or when the user manually disconnects via Rabby’s interface.

5. Rabby enforces strict origin validation — it rejects requests from iframes, cross-origin redirects, or mismatched hostnames even if the URL appears visually similar.

Step-by-Step Connection Without Over-Permissioning

1. Navigate directly to the dApp’s verified domain — never click links from DMs, emails, or third-party aggregators.

2. Click “Connect Wallet” and select Rabby from the wallet list — ensure no other injected wallets are active in the same browser profile.

3. In the Rabby pop-up, verify the exact hostname matches the one in your browser’s address bar — including subdomain and TLD.

4. Decline any request labeled “Approve all tokens”, “Unlimited allowance”, or “Full contract access” unless you have audited the dApp’s code and understand the implications.

5. Use Rabby’s built-in permission toggle to restrict access to only the specific account and network needed — avoid selecting “All accounts” or “All networks”.

Recognizing Risky Permission Prompts

1. A prompt asking for approval of more than three ERC-20 tokens at once is highly unusual and warrants immediate rejection.

2. Any signature request that includes raw hex data without human-readable description should be treated as suspicious.

3. Rabby flags non-standard contract interactions with a red warning icon — do not override this unless you’ve validated the contract address on Etherscan or Blockchair.

4. If the prompt shows “Gas estimation failed” alongside an unusually high gas limit (>500,000), it may indicate a reentrancy or infinite loop attempt.

5. Requests originating from localhost or 127.0.0.1 without prior local development setup should be blocked outright.

Managing Active Connections

1. Open Rabby extension → click the gear icon → go to “Connected Sites” to view all currently authorized domains.

2. Each entry displays last used timestamp, network, and granted scopes — revoke any with “Read + Sign” if only balance checks were intended.

3. Rabby supports per-site permission revocation — clicking “Remove” severs all access without affecting other connections.

4. The “Auto-reject unknown sites” setting can be enabled under Privacy Preferences to block unauthorized connection attempts silently.

5. Connected site metadata is stored locally in IndexedDB — no server-side logging or telemetry is transmitted during connection flow.

Frequently Asked Questions

Q: Does Rabby store my private key when I connect to a dApp?No. Rabby never transmits or stores private keys on remote servers. All cryptographic operations occur inside the browser sandbox using Web Crypto API.

Q: Can a dApp see my transaction history after I connect?Only if you explicitly approve a request to fetch past transactions via eth_getLogs or similar RPC methods — Rabby does not expose historical data by default.

Q: Why does Rabby ask for “Sign Message” permission during initial connection?This is used solely for domain binding verification — the message contains a cryptographically signed nonce tied to the current hostname and expires within 60 seconds.

Q: Is it safe to keep Rabby connected to multiple dApps simultaneously?Yes, provided each connection was individually reviewed. Rabby isolates permissions per origin — no dApp gains visibility into another’s approved scopes.
