LayerZero is a Canada-based team building the interoperability protocol LayerZero.
The protocol allows smart contracts to communicate among many or any blockchains easily. The LayerZero protocol is only messaging, no intermediary layer, wrapping, etc.
It has instant support for any chain supporting the messaging layer with no extra trust assumptions or separate consensus.
This makes Omnichain NFTs possible.
Omnichain NFTs are NFTs that can exist in two or more chains.
