Since mid-November, go-lachesis development has been our main focus for the second mainnet (separate from the Decentralised Finance Chain — XAR network) with Ethereum Virtual Machine Support.

We have also begin working on upgrading and refactoring our mobile, desktop, and web wallets, as well as an explorer and api for Go-lachesis.
