The testnet is a small test DigitalBits network, open to developers.
digitalbits.io runs 3 digitalbits-core validators on this test network. Set your digitalbits-core to connect to us by using this configuration. You can also find a Frontier instance that is connected to the testnet.
The testnet is for, well, testing. It’s occasionally reset, so don’t get attached to any balances or accounts that you have on it.
