From a developer perspective, Kaia support of Ethereum Prague Improvements and Updates begs the following questions:

  1. Is mainnet integration for 7702 completed on Kaia?
  2. Does Kaia wallet now support 7702?
  3. Does Kaia have an sdk that abstracts away the endpoints exposed by the 7702, similar to wagmi, or is wagmi suitable on Kaia to integrate 7702?

side-question: how can I run a demo of 7702 on Kairos using native USDT since it’s not deployed on Kairos?
A demo showcase would make sense, I believe.
