# Canonical bridge

## Definition

A canonical bridge is the bridge mechanism officially associated with a particular blockchain or Layer 2 protocol for moving assets or messages to and from its settlement layer.

## What it means in practice

Canonical bridges often have protocol-specific withdrawal, proof and waiting rules that differ from third-party liquidity bridges.

## How this concept appears in Terenval Wallet

Terenval can hold accounts on supported L2 networks, while any canonical bridging process remains governed by the relevant L2 protocol and bridge interface.

**Important:** Use the official protocol documentation to verify the canonical bridge URL and withdrawal behavior.
