# Interoperability

As we use Binance as the substrate of our BSC-1155/BSC721 implementation, any platform / wallet that supports BSC-1155/BSC-721 will be able to inspect and use our ASSET. This means independent developers could rely on the plethora of ASSETS our players will be creating. 

Osiris gaming environment will be divided into 5 types of tokens: 

● OSR (our game currency used across the system) 

● LANDS (Worlds in which players play that are created by the community) 

● ASSETS (Voxel models created by players and traded in the marketplace) 

● GEMS burnt to give attributes to ASSETS. They are BEP20 tokens 

● CATALYSTS burnt to mint ASSETS. Depending on their power, they allow users to associate a certain number of GEMS to an ASSET. They are BEP20 tokens.

Token contracts are responsible for: 

● Keeping track of creator (the address that minted the token) 

● ownership 

● transfers 

● Emitting events when the state changes
