Kava co-founder and CEO Scott Stuart said that if Ethermint (now Evmos) is not free to use, Kava will build and maintain an EVM-compatible module that is free to use forever.
Ethermint developed by Cosmos in October 2021 was upgraded to Evmos due to trademark issues and scope expansion, which allows interoperability with the Ethereum mainnet, EVM-compatible environment, and other BFT chains via IBC.
