# Malicious dApp

## Definition

A malicious dApp is a decentralized-application interface or contract interaction designed to trick users into unsafe signatures, approvals, transfers or secret disclosure.

## What it means in practice

The website can look professional while the underlying request authorizes a drainer or excessive token allowance.

## How this concept appears in Terenval Wallet

When a dApp connects to Terenval through WalletConnect, users must still inspect each request; connection compatibility is not a security endorsement.

**Important:** Disconnecting from a malicious dApp may not revoke approvals already written on-chain.
