We have forked Cosmos’ Big Dipper explorer, and customized it for our network.
For the time being it lives here: https://explorer.mainnet.enigma.co
Our repo is here: https://github.com/enigmampc/big_dipper
It had been live since the day we launched the network, and have recently fixed some small issues, so it seems to be running fine. If you find anything wrong, you are most welcome to open an issue, or even better, submit a fix!
Anyone can now clone it and run their own version.
