Zip/Unzip Fees

Zipping and unzipping assets on Zipper incurs no additional service fees beyond the network transaction costs required to process deposits and withdrawals.

📌 Zipper does not charge percentage-based fees - users only pay the necessary blockchain gas fees to facilitate the transfer of assets.

How Are Fees Calculated?

• Deposit (Zip): Users pay the network fee required to send their assets to the Zipper vault on the original blockchain. Fabric Labs sponsors the network costs on Fabric for minting the zAsset and transferring to your user wallet.

• Withdrawal (Unzip): Users pay the network fee required to process the withdrawal and transfer the original asset to their destination address from the Zipper vault. Fabric Labs sponsors the network costs on Fabric for burning the zAsset.

• Fees are dynamically calculated based on real-time network conditions and are displayed before confirming a transaction.
