Setup guide

We will set it up for you free of charge. Send us your wallet address and the miner will mine for you alone. If you do not have a wallet yet, we will help you create one.

How to set up an ASIC miner

Connect the network first, then the power. Connect the miner to your router with a network cable, on the same network as your computer. Only then switch it on.
Find the IP address. You can find it in your router’s list of devices or with the manufacturer’s tool.
Log in. Enter the IP address in your browser. The default username and password are in the manufacturer’s manual – we will gladly send it to you.
Set up the pool. Enter the pool address in the form stratum+tcp://…; as the Worker, enter your pool account name or wallet address, a full stop and the machine name, and x as the password. Save.
Check that it is mining. After a few minutes the miner will start mining. You can check the hashrate on the pool’s website.
