The team felt that the existing WTZ Fa2 1:1 wrapped tez didn't work for them because of the 0.1% fee on withdrawal, the fact that it doesn't have an oracle, and the fact that it isn't just a 1 to 1 wrapped token like WETH on Ethereum. This makes it difficult to use for protocols such as money markets. The team is looking into whitelisting a contract to circumvent the fee, and is also looking into using Ubinetic, Harbinger, and an on-chain oracle for cTez. However, they are also considering the possibility of simply DIYing the token, as it is only used on the platform and won't really mess with the market. This is because the nature of WTZ is a little bit different from WETH, as it works more similarly to a fund with shares, and also has the 0.1% fee on withdrawal.
It is important to have open conversations about the basic building blocks that we're all going to need for years to come, as interoperability is key in DeFi. By discussing the pros and cons of different solutions, we can ensure that we are making the best decisions for our projects.
