# Smart contract

## Definition

A smart contract is program code stored at a blockchain account that executes according to network rules when called by a transaction.

## What it means in practice

On Ethereum, smart contracts can implement tokens, exchanges, lending systems, NFTs and other application logic.

## How this concept appears in Terenval Wallet

Terenval can sign supported EVM transactions that interact with smart contracts, including requests initiated through compatible dApps.

**Important:** A contract call can do more than transfer ETH, so inspect permissions and transaction details before signing.
