There are two tokens involved in the VeChain system. First, there’s the VeChain (VET) token, which transmits value. Second, there’s the VeChain Thor Energy (VTHO) token, which provides a smart contracts platform.
The two-token system acts as a stabiliser, so that dApp developers have a more predictable environment in which to create new software. VET is the token that is of greater interest for investors.
