⛏️ 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.
• Registered payout profile — save all three addresses once on the miner dashboard.
• 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: Register payout addresses

Open the miner dashboard and save your XEC payout addresses. You only do this once.

Step 2: Choose your port

Pick the port below that matches your hashrate (ports 3334–3340 (legacy 3350–3356 also work)).

Step 3: Configure your miner

Use your ecash:q... address as the stratum username. Payouts always go to the correct per-coin address when the pool switches — you do not reconfigure your miner when the active coin changes. The .workername suffix is optional (e.g. bc1q...abc.bitaxe1).

Step 4: Start mining & check stats

Within a minute you should see accepted shares. View stats on the miner dashboard using any registered 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).
