⛏️ eCash Mining Connection Guide

📋 What You Need

• eCash address, use your ecash:q... address. See our Wallet Address Guide or generate a wallet in your browser.
• eCash wallet, you control the private keys for your ecash:q... address (never use an exchange deposit address).
• SHA-256 mining hardware, Bitaxe, NerdMiner, ESP32, ASIC, or similar.
• Internet connection, your miner must stay online to submit shares.

🔧 How to Connect (Step-by-Step)

Step 1: Get your ecash:q... address

Use an existing eCash wallet or generate one in your browser. This address is your stratum username and where payouts are sent.

Step 2: Choose your port

Pick the US port below that matches your hashrate (3334–3340). If you are in Europe, use eu.xec.hmpool.io with the matching EU port (3350–3356). Bitaxe in Europe is 3352.

Step 3: Configure your miner

Use your ecash:q... address as the stratum username. The .workername suffix is optional but recommended for multiple rigs (e.g. ecash:q....bitaxe1).

Step 4: Start mining & check stats

Within a minute you should see accepted shares. View stats on the miner dashboard using your ecash:q... address.

❓ Common Questions

• Why was I rejected at authorize?, Invalid or malformed ecash:q... address, or pool maintenance.
• Can I use a Bitcoin (BTC) address?, No. BTC, BNB, and Trust Wallet default coins will not work. You need XEC addresses.
• Why rejected shares?, Usually the wrong port for your hashrate. Try a higher port.
• What is a worker name?, Optional label after your address to identify multiple rigs (e.g. ecash:q....rig2).
