# Bridges {% hint style="warning" %} Please note that this section is under active development. {% endhint %} ### What is a Bridge? Bridges are a way to connect two different blockchains. They are a special type of smart contract that allows you to lock up tokens on one blockchain and mint the same amount of tokens on another blockchain. This is a very useful feature, as it allows you to transfer tokens between different blockchains. For example, you can transfer tokens from the Ethereum blockchain to the Arbitrum blockchain. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
