Haust wallet

What is Haust (HAUST)?

HAUST is the native asset of Haust Network, a zkEVM rollup built with Polygon's CDK toolkit and connected to Ethereum for settlement. Its chain is designed around account abstraction, so on Haust itself a wallet can be a smart account rather than a plain key, and the network's own applications - a lending market and a swap venue - are where the token does its work.

The practical point for a holder is that the token exists in more than one place. What a hardware wallet keeps is the ERC-20 record on Ethereum: an ordinary token balance sitting under your address, moved by an Ethereum transaction and paid for in ETH. Keep a little ETH in the same wallet or a transfer will sit there unsendable, no matter how large the HAUST balance is. The same token bridged onto Haust Network is a separate entry with its own gas rules; a bridge contract, not a transfer, is what moves a balance between the two sides, and a plain send to a bridge address is the classic way people lose a position.

Supported networks in Tangem (1): Ethereum. The app tracks the balance and names the network a transfer leaves on before the card is tapped, which is the check worth making with an asset whose ERC-20 form and rollup form share a ticker. Holding the Ethereum-side HAUST on a card you sign with deliberately, rather than in a browser session open to the chain's own apps, matches how most people actually use this token: rarely, and on purpose.
