I think that it is gonna be a strong cooperation. Both tokens have their own networks with specific benefits. Hope this defi project of theirs is gonna be a success.
While the idea of converging Waves and Tron seems very cool, these blockchains are differ a lot as both use their own wallets and languages of smart contract. This problem will be solved by using the protocol Gravity which is the unique stuff. It will let languages, Ride and Solidity, being used, allowing Tron or Waves tokens to work on both blockchains.
