Double-Check Before You Sign

Palmera adds an extra layer of verification with QR-based Two-Factor Validation (2FA). Before signing, users can independently confirm transaction details on an external device, ensuring accuracy and preventing unauthorized changes. With instant feedback, every approval is fully informed and secure.
qr step 1qr Stp 2QR Step3QR Step 4
1. Scan to Verify
The extension generates a QR code containing key transaction details. Users scan the QR code with an external mobile app to initiate verification.
2. Review Transaction Details
The mobile app extracts and displays the transaction in a human-readable format, showing key parameters such as recipient, amount, and contract function.
3. Verified Transaction
If the transaction matches expectations, the user confirms approval with "Trust & Sign." The extension then proceeds with signing and submitting the transaction securely.
4. Warning for Suspicious Transactions
If discrepancies are detected—such as mismatched addresses, altered amounts, or an invalid security signature—the app alerts the user to potential risks. The transaction can then be stopped before signing.
Where This Extension Protects You
Detecting Mismatched Transaction Details
A compromised dApp may display different transaction details than what is actually being sent. The extension analyzes the data and alerts you to any inconsistencies before you sign.
Reviewing Large-Value Approvals
For high-stakes transfers, the extension highlights any unexpected changes in the transaction payload, reducing the risk of major losses. The extension verifies the transaction parameters and highlights any unexpected changes for your review.
Flagging Unusual Transaction Requests
A contract you interact with regularly suddenly requests a new or unexpected approval. The extension analyzes the request and notifies you if anything looks suspicious.
Alerting on Potentially Manipulated Transactions
You access a dApp through what appears to be a trusted source, but the transaction data has been altered. The extension detects potential manipulation and warns you before you proceed.

Simple and Familiar Process

QR codes and two-factor authentication (2FA) make security effortless, using the same trusted methods as traditional finance.

Extra Protection for High-Value Transactions

Add an extra layer of trust for DAO treasuries, institutional funds, and large transfers, reducing the risk of costly mistakes.

Security Without the Delays

Automated checks and real-time alerts keep transactions safe without slowing you down.

Independent Manual Verification

For added assurance, verify transaction details on an external website before signing—giving you full control over every approval.
