0xSplits does not support zkSync

Summary

As per the docs: 0xSplits has not launched on zkSync, resulting in Titles not being able to launch on zkSync.

Vulnerability Detail

The docs state the following:

//On what chains are the smart contracts going to be deployed?
//Ethereum, Base, OP, Zora, Blast, Arbitrum, zkSync, Degen

However,zkSync is not supported by 0xSplits, as you can see here.

Because zkSync is not supported by 0xSplits, the external call createSplit() will not be able to be executed.

    /// @notice Creates a new fee route for the given {Edition} and attributions.
    /// @param edition_ The {Edition} for which to create the route.
    /// @param tokenId_ The token ID associated with the route.
    /// @param attributions_ The attributions to be associated with the route.
    /// @param referrer_ The address of the referrer to receive a share of the fee.
    function createRoute(
        IEdition edition_,
        uint256 tokenId_,
        Target[] calldata attributions_,
        address referrer_
    ) external onlyOwnerOrRoles(ADMIN_ROLE) returns (Target memory receiver) {
        Target memory creator = edition_.node(tokenId_).creator;

        if (attributions_.length == 0) {
            // No attributions, pay the creator directly
            receiver = creator;
        } else {
            // Distribute the fee among the creator and attributions
            (address[] memory targets, uint256[] memory revshares) = _buildSharesAndTargets(
                creator, attributions_, edition_.feeStrategy(tokenId_).revshareBps
            );

// Create the split. The protocol retains "ownership" to enable future use cases.
            // @audit this process seems odd
            receiver = Target({
->              target: splitFactory.createSplit(
                    SplitV2Lib.Split({
                        recipients: targets,
                        allocations: revshares,
                        totalAllocation: 1e6,
                        distributionIncentive: 0
                    }),
                    address(this),
                    creator.target
                    ),
                chainId: creator.chainId
            });
        }

        _feeReceivers[getRouteId(edition_, tokenId_)] = receiver;
        referrers[edition_] = referrer_;
    }

Consequently, createRoute() will not execute, effectively breaking the protocol.

Impact

This project will not be able to launch on zkSync.

Ultimately, the core functionality is broken when launching on zkSync
