Multiwrap Contract Issue

[westonnelson]

Hello,

I have been unable to compile the Multiwrap.sol contract in several different compilers.

It appears to be related to

  --> gist-d32c71f38ce15aad5b54f9df9312f73d/ERC1155Holder.sol:35:27:
   |
35 | contract ERC1155Holder is ERC1155Receiver {
   |                           ^^^^^^^^^^^^^^^

When removing the 1155 information in the TokenStore.sol file, it compiles successfully which enables the ERC-20 and ERC-721 functionality alone.
