How to dual mine ETC and ALPH with T-Rex?

In this guide we will show you how to set up dual mining of Ethereum Classic and ALPH on minerstat with your LHR cards. Keep in mind that it is required to have sufficient enough of VRAM on your GPU for such mining to work. You can find current DAG file sizes on our DAG size calculator.

About dual mining In dual mining two coins are mined at the same time at different pools of your choosing. The coins don't have to be of same algorithm, but to be able to dual mine, your mining client needs to support dual mining.

1. Pools

First, open the address editor and add a new tags (POOL:ETC) which will hold ETC stratum address and (POOL:ALPH) will hold the ALPH stratum address. In this example, we will use 2miners and herominers:

  • ETC: stratum+tcp://etc.2miners.com:1010
  • ALPH: stratum+tcp://de.alephium.herominers.com:1199

2. Wallets

In the next step you need to save your wallet addresses to your address editor. Create new tag (WALLET:ETC) under wallets with your ETC wallet address and tag (WALLET:ALPH) with your ALPH wallet address.

3. Worker's config

Open worker's config and select TREX as a default mining client.

4. TREX config

Click on [Advanced] tab and update the mining client's configuration so that it will be defined as:

{
"pools": [
{
"user": "(WALLET:ETC)⁣.(WORKER)",
"worker": "(WORKER)⁣",
"url": "(POOL:ETC)⁣",
"pass": "x"
}
],
"no-nvml": false,
"api-bind-http": "127.0.0.1:4068",
"json-response": true,
"pci-indexing":true,
"retries": 3,
"retry-pause": 5,
"timeout": 500,
"no-watchdog":true,
"algo": "etchash",
"dual-algo": "blake3",
"user2": "(WALLET:ALPH).(WORKER)",
"url2": "(POOL:ALPH)",
"pass2": "x",
"exit-on-cuda-error": true,
"exit-on-connection-lost": false
}
