# Non-custodial wallet

## Definition

A non-custodial wallet is a wallet model in which the user controls the cryptographic recovery/key material rather than delegating key custody to an exchange or wallet provider.

## What it means in practice

This gives the user direct signing authority but also makes backup and operational security the user's responsibility.

## How this concept appears in Terenval Wallet

Terenval Wallet is non-custodial. Its current production security boundary keeps seed/recovery phrase processing on the user's device instead of sending the phrase to Terenval servers.

**Important:** Self-custody removes one custodian risk but does not remove phishing, device compromise or user-error risk.
