How to mine Iron Fish (IRON)

1Get a wallet

You need a Iron Fish address to receive what you mine. Use an official wallet:

• Iron Fish Node App - the official desktop wallet
• Iron Fish with Ledger

Public addresses are 64 hexadecimal characters (32 bytes).

Write the seed phrase down on paper and keep it offline. The miner and the pool only ever need the public address.

2Pick a pool

A pool combines many miners so you get paid steadily instead of waiting to find a whole block. Live fees and payouts for every pool are on the pools table.

Kryptex regions: add -eu, -us, -br, -sg, -hk, -ru or -ae after the coin in the host name (for example iron-eu.kryptex.network). For TLS use port 8017 with stratum+ssl:// (Rigel, BzMiner) or the miner's TLS switch (SRBMiner --tls true, lolMiner --tls on). Kryptex logins are wallet/worker. HeroMiners has servers in many regions: replace de with fr, es, fi, ru, ca, us, us2, us3, br, hk, kr, sg, tr or au. The same port takes plain and TLS connections. Solo mining: solo:YOUR_WALLET.

3Pick a miner

BzMiner and WildRig Multi do not list FishHash.

4Set it up

Replace YOUR_WALLET with your address and YOUR_WORKER with a name for this machine. On Windows, save the line as a .bat file in the miner's folder and double-click it. On Linux, run it from the miner's folder.

@echo off
cd /d "%~dp0"
SRBMiner-MULTI.exe --disable-cpu --algorithm fishhash --pool iron.kryptex.network:7017 --wallet YOUR_WALLET/YOUR_WORKER
pause

./SRBMiner-MULTI --disable-cpu --algorithm fishhash --pool iron.kryptex.network:7017 --wallet YOUR_WALLET/YOUR_WORKER

@echo off
cd /d "%~dp0"
lolMiner.exe --algo FISHHASH --pool iron.kryptex.network:7017 --user YOUR_WALLET/YOUR_WORKER
pause

./lolMiner --algo FISHHASH --pool iron.kryptex.network:7017 --user YOUR_WALLET/YOUR_WORKER

@echo off
cd /d "%~dp0"
rigel.exe -a fishhash -o stratum+tcp://iron.kryptex.network:7017 -u YOUR_WALLET/YOUR_WORKER
pause

./rigel -a fishhash -o stratum+tcp://iron.kryptex.network:7017 -u YOUR_WALLET/YOUR_WORKER

5Check it works

• Within a few minutes the miner should print accepted shares. Rejected or stale shares above a few percent mean a problem with the connection, the clocks or the pool address.
• Open your pool's dashboard and search for your address. Your worker appears after its first shares; pool hashrate settles over an hour or so.
• Watch temperatures for the first hour: GPU core, hotspot and memory.

Warnings and cautions

Iron Fish-specific

• Project in maintenance mode. The Iron Fish Foundation's 2026 post says development slows, grants end, the Discord closes and Iron Fish Devco was acquired by Coinbase; the Foundation keeps the bootstrap nodes, explorer and website running. Weigh that before buying hardware for this coin.
• VRAM: the FishHash dataset is fixed at 4,608 MB plus about 72 MB of cache, and does not grow.
• Drivers per lolMiner: AMD RX 6000 needs 20.40 or newer and RX 7000 22.40 or newer; NVIDIA RTX 30 needs CUDA 11 and RTX 40 CUDA 12.

For every coin

• Download miners only from the official page. Use the GitHub release or website linked in the miner table. Fake miners that steal wallets or mine to someone else are common. Where the developer publishes SHA-256 checksums, compare them before the first start (Windows: Get-FileHash .\file.zip -Algorithm SHA256; Linux: sha256sum file.tar.gz).
• Antivirus warnings. Windows Defender and other antivirus tools flag almost every GPU miner as a "potentially unwanted" program, because malware bundles them. Add a folder exclusion only for a miner you downloaded from its official page and checked, and never turn protection off as a whole.
• Your seed phrase is never needed. A miner and a pool only need your public address. Anyone who asks for your seed (recovery) phrase or private key is trying to steal your coins.
• Power, heat and hardware. Mining runs the card at full load all day. Watch GPU, hotspot and memory temperatures, keep the room ventilated, and do not leave a rig running unattended near anything flammable. A power limit or undervolt usually costs a little hashrate and saves a lot of power. Check that your power supply and cables are rated for the load.
• Profit is an estimate. Price, network hashrate and pool luck change every hour. The calculator shows today's numbers, not a promise. Small coins can be hard to sell, and taxes on mined coins apply in many countries. Nothing here is financial advice.
