globe-pointerWhat Is Zipping/Unzipping?

Zipper enables users to securely convert assets from external blockchains into Fabric-compatible zAssets (wrapping) and return zAssets back to their original form (unwrapping). This process is simple, efficient, and fully backed 1:1 by the original asset.

Wrapping (Zipping)

Wrapping transforms assets from external blockchains into Fabric-compatible zAssets.

How It Works - Summary

  1. Deposit: The user deposits their external blockchain asset (e.g., ETH or USDT) into Zipper’s secure on-chain vault.

  2. Minting: Zipper mints an equivalent amount of zAssets on Fabric (e.g., zETH or zUSDT) and transfers them to the user’s Fabric wallet.

  3. Traceability: The original asset is stored in a multi-signature vault, and the zAsset is linked to both its Fabric and original chain contract addresses.

Example

  • The user deposits 10 USDT from Ethereum into Zipper.

  • Zipper mints 10 zUSDT on Fabric and sends it to the user’s wallet.

Unwrapping (Unzipping)

Unwrapping converts Fabric-compatible zAssets back into their original external blockchain assets.

How It Works - Summary

  1. Send zAssets: The user sends their zAssets (e.g., zETH or zUSDT) to Zipper.

  2. Burning: Zipper burns the zAssets, removing them from circulation on Fabric.

  3. Withdrawal: The original asset is released from the vault on the respective external blockchain and sent to the user’s external blockchain wallet.

Example

  • The user sends 10 zUSDT(Ethereum based) to Zipper.

  • Zipper burns the 10 zUSDT and sends 10 USDT back to the user’s Ethereum wallet.
