# Transaction signing

## Definition

Transaction signing is the cryptographic act of authorizing transaction data with a private key so a network can verify that the authorized account approved the action.

## What it means in practice

Signing does not necessarily mean 'sending coins'; wallets may also sign messages, contract interactions or approvals depending on the network and application.

## How this concept appears in Terenval Wallet

Terenval Wallet presents transaction flows for supported networks and users should verify destination, network and amount before authorizing a signature.

**Important:** A valid signature can authorize harmful actions too, so understand what the wallet is asking you to approve.
