Three steps · no sign-up · connect and mine

⚡ In a hurry — one command

Already have your 0x02 address? Replace the placeholder and run (Windows: PowerShell in the xmrig folder; give each machine a different name, e.g. .rig1 / .rig2).

Your address and rig name stay in this browser's localStorage — never sent to the pool.

Prepare a payout address

The address only — never a seed phrase or private key. This pool holds no custody. Easiest: grab the Zycord Wallet desktop app (zycord.com → Downloads — Windows/macOS/Linux) and create a wallet to get your 0x02 address. Terminal equivalent:

zcd wallet new --out zcd.key   # creates a 24-word seed — WRITE IT DOWN, store offline
# follow the prompts → you get a 0x02 persistent address
# that address = miner identity + payout address, goes into XMRig's -u
Create a wallet in five steps (~3 min · desktop app recommended)






Advanced: create from the command line (optional)

zcd wallet new --out zcd.key      # 24-word seed, passphrase >= 8 chars
zcd wallet address --key zcd.key  # prints one-shot 0x01 + persistent 0x02
zcd wallet restore --out zcd.key  # type the 24 words to rebuild

Terminal output example (mnemonic masked)

$ zcd wallet new --out zcd.key
passphrase for the new key file: ********
confirm: ********

Recovery phrase — write these 24 words down now, on paper, in order.
They restore this wallet on any computer, and this is the only time they are shown.
Anyone who reads them can spend everything this wallet holds.

Install XMRig 6.26.0

Download XMRig 6.26.0 (official release, verify SHA256SUMS). Do NOT use --randomx-mode light — rx/2 light-mode hashes disagree with verification and shares will be rejected. On cloud hosts / containers (Clore, LXC, some KVM) add --randomx-no-numa, or the dataset binding fails and every share is rejected (symptom: log full of skipped (can't bind memory) with accepted stuck at 0).

Configure & connect

Full commands in the "Full Startup Command" section above (ports follow the network switch); set login to your 0x02 address, optionally suffixed .rig1 to label devices — one unique name per machine (rig1, rig2, or the hostname); two machines sharing a name merge into one row. Your workers appear on the leaderboard instantly.

Full Startup Command

Bare metal / dedicated (default is optimal — omit --threads and XMRig uses every logical core):

Cloud host / container (NUMA workaround added):

How Payouts Settle

Order of magnitude: at 1% of network hashrate, expect the first payout within several hours (maturity + batching threshold); a growing "pending" figure before that is normal.

Troubleshooting

SymptomFix
no template available · endless retryGenesis not reached yet (before mainnet Oct 07): idling is normal, mining starts automatically on time
skipped (can't bind memory) · accepted 0%Container forbids NUMA: add --randomx-no-numa and restart
share below job target loopLight mode by mistake: remove --randomx-mode light
occasional Block expired (<5%)Normal block-race discard, no action needed

Startup Config


    
Security notice: miners submit only work shares and a payout address. This pool holds no custody and needs no keys; payouts are on-chain certificates from the pool wallet straight to your address. Guard your seed phrase — anyone asking for it is a scam.
