# Transaction hash

## Definition

A transaction hash is a cryptographic identifier derived from transaction data and used to reference a specific transaction on a blockchain.

## What it means in practice

A hash lets wallets, explorers and users look up transaction status without exposing private keys or recovery phrases.

## How this concept appears in Terenval Wallet

Terenval can use or display transaction identifiers for supported network activity, which users can independently check in a suitable explorer.

**Important:** A transaction hash is public diagnostic data and is normally safe to share with support; a seed phrase or private key is not.
