# Multi-chain approach

Currently, the ZeroLabs Tokenization Protocol **supports multiple blockchains** in a *limited way*.

In the initial implementation of the protocol, we have a **separate** set of ERC-1888 **smart contracts** deployed on **each blockchain**, and the Certificates are *non-transferrable* between them.

In the future, these Certificates **will be bridgeable** to other blockchains. Read more [here](https://docs.zerolabs.green/zerolabs-tokenization-module/future-improvements/bridging).
