⛏ SHA256 Mining

ESP32 corner

On a big pool, an ESP32 “NerdMiner” is a lottery ticket that will almost certainly never win. Here it can find real blocks.

These ports mine small coins whose difficulty is low enough for a tiny miner to win now and then – every block pays straight to your own address, inside the block. Free for every member.

Each port is for ESP32-class miners only: an account using more than 5 MH/s there is disconnected for a while. Bitaxes and bigger miners belong on the main ports (see the home page).

Start mining in 3 steps

1. Make a free account

Sign up with a Bitcoin address – it becomes your miner's username. No Bitcoin address yet? Make one here for free (you only need a pen and paper).

2. Add your POL and EMB and FXTC addresses

On your dashboard, under Payout addresses, use “Fill in all my addresses from my 12 words”, or paste addresses from the coins' own wallets. That is where your ESP32's blocks are paid. Without an address for a coin, the pool turns your miner away on that port.

3. Point your ESP32 at the pool

Open your miner's set-up page (on a NerdMiner: hold the button while it starts, then join its NerdMinerAP Wi-Fi network) and enter:

SettingWhat to type
Pool / stratum addressstratum.shears.co.uk
Port3690 for POL or 3700 for EMB or 3710 for FXTC
Username / BTC addressyour Bitcoin address (the one you signed up with). Add .name to tell several devices apart, e.g. bc1q….esp1
Passwordx

Works with NerdMiner, NMMiner and other ESP32 stratum firmwares. Some firmwares want the pool written as stratum+tcp://stratum.shears.co.uk with the port in its own box.

Honest bit

  • The blocks are real – they pay straight to your own address on each coin's blockchain.
  • These are small coins: a block is fun and genuine, but not worth much money. Mine for the joy of it.
  • How often your ESP32 wins depends on the coin's difficulty and how many other ESP32s are mining – check the table above.
  • We never hold your coins and we will never ask for your 12 words or wallet file.
