# What To Do With zAssets?
Once an asset has been **zipped** through Zipper, it becomes a **Fabric-native zAsset**, unlocking new opportunities within the ecosystem. Whether you’re looking to trade, interact with decentralized applications, or simply hold assets on Fabric, zAssets provide a **versatile foundation for expanded utility**. *** #### **Trading on Polyester** zAssets can be traded on **Polyester**, Fabric’s decentralized exchange (DEX). Unlike traditional AMM-based DEXs, Polyester operates with an **order book system**, enabling advanced trading features like **limit orders, TWAP execution, and institutional-grade market tools**. Since all assets on Fabric exist as **zAssets**, users can trade **zBTC, zDOGE, zXRP, and other tokenized versions of external assets**, which are **backed 1:1** by their original counterparts. Unlike other DEXs that primarily support ERC-20 assets, Polyester allows trading pairs that include **major non-EVM assets** in a fully decentralized manner - without relying on liquidity pools. *** #### **Using zAssets in Fabric dApps** Beyond trading, zAssets are designed to be a **core building block for decentralized applications on Fabric**. As the ecosystem evolves, developers and community members can create new use cases for zAssets, including possibilities like **lending, staking and on-chain yield strategies**. The **Fabric blockchain is permissionless**, meaning anyone can deploy smart contracts and build applications that integrate zAssets in innovative ways. If you're a developer, now is the time to explore **building on Fabric** and leveraging zAssets to power **new DeFi models, AI-driven contracts, and autonomous dApps**. *** #### **Unzipping & Exiting Fabric** If users ever want to return their assets to their original blockchain, they can **initiate an unzipping transaction** through Zipper. This process burns the zAsset on Fabric and **releases the original asset back to the user’s wallet** on the external chain, ensuring a **trustless and verifiable** 1:1 exchange. *** #### **Beyond DeFi: The Future of zAssets** The possibilities for zAssets extend far beyond trading and DeFi. **With real-time information, AI-driven automation, and Fabric’s decentralized computing capabilities**, entirely new applications can be built that go beyond what’s possible on traditional blockchains. The combination of **programmable assets, AI Agents, and smart contract logic** could lead to **financial applications, autonomous marketplaces, and Web3 innovations that have yet to be explored.** Developers and innovators will shape the next phase of the Fabric ecosystem, using zAssets in ways that push the boundaries of blockchain technology.
