# Mainnet Bridge

<figure><img src="/files/00phSF7exk9MFeZeyV1u" alt=""><figcaption></figcaption></figure>

* ALTAVA LAND's ecosystem is fundamentally built on the Polygon network for efficient operation, allowing ALTAVA LAND, which is based on Ethereum, to migrate to Polygon Layer 2 and reap the maximum benefits of the ecosystem.
* Currently, it provides a bridge connected to the Harmony network. Through the Harmony bridge, users can transfer their LAND and TAVA holdings from the Ethereum blockchain to the Polygon(Layer 2), and vice versa.
* In the future, ALTAVA LAND plans to develop and provide its own bridge.
