# Omnichain

Omnichain tokens can be sent across different chains without fees or liquidity needed.\
\
The chain transfers are accomplished with a lock-and-mint model. In this model, users lock assets into a main chain, while simultaneously, the new chain mints an equal amount of wrapped tokens. When converting back, these wrapped tokens are burned to unlock the locked-up assets. \
\
Transfers between non-main chains involve burning the tokens on that one chain, and minting the exact same amount of tokens on another.
