Zephyr (ZEPH) mining pool

testnet

RandomX (rx/0) · CPU · Block time 120s · Confirmations 60 · PPLNS

Zephyr uses RandomX, the CPU algorithm of Monero, on a much smaller network — a few hundred CPUs are a visible share of it, so blocks and payouts come steadily. XMRig or SRBMiner, huge pages on, and you mine to your own ZEPH address.

How to connect

Point your miner at stratum.hashlak.com with the port that fits your setup. Use the hostname, never an IP: the Stratum server can move behind the same name.

Port	Use	Start difficulty	TLS
stratum.hashlak.com:3302	CPU	15000	—
stratum.hashlak.com:3402	farms / proxies	200000	—
stratum.hashlak.com:3502	CPU, TLS	15000	✓

Fee: 0% · PPLNS
Minimum payout: 1 ZEPH
Network fee: paid by the pool

Payouts run every 10 minutes once your balance reaches 1 ZEPH. Mine to a wallet you control, not to an exchange deposit address.

Miner commands

Replace {wallet} with your address and {worker} with a name for the rig, then run.

XMRig

xmrig -a rx/0 -o stratum.hashlak.com:3302 -u {wallet} -p {worker}

SRBMiner-MULTI

SRBMiner-MULTI --algorithm randomx --pool stratum.hashlak.com:3302 --wallet {wallet} --worker {worker}

XMRig, TLS

xmrig -a rx/0 -o stratum.hashlak.com:3502 --tls -u {wallet} -p {worker}

Antivirus software usually deletes or blocks miners — add an exclusion for the miner folder (ESET: Setup → Advanced setup → Detection Engine → Exclusions). Note: opening a Stratum port in a browser bans your IP for 60 s, a wrong address for 3 s per retry, and 50% invalid shares for 10 minutes.

Wallets

Zephyr wallets (official site) — Desktop GUI, command line and web wallet are all linked from the official site. Mine to the primary address (ZEPHYR…), never to a subaddress (ZEPHs…).
zephyr-wallet-cli (GitHub releases) — The command-line wallet shipped with the node, for people who run their own zephyrd.

Download wallets only from the official site or the GitHub releases linked above. We never ask for private keys or seed phrases.

Common questions about mining Zephyr

What do I need to mine Zephyr?

A CPU with about 2 GB of free RAM per miner and huge pages enabled: on Windows run XMRig as administrator once, on Linux sysctl -w vm.nr_hugepages=1280. Without huge pages you lose 30–50% of the hashrate. Modern desktop CPUs do a few kH/s (approximate).

Which address do I mine to?

Your wallet's primary address — ZEPHYR… on mainnet, ZPHT… on the test network. Subaddresses (ZEPHs…) are refused on both networks. The badge at the top of this page shows the pool's current network.

When and how am I paid?

Every 10 minutes the pool pays every balance above 1 ZEPH and covers the network fee itself. Blocks need 60 confirmations. If a payout arrives a little later than the previous one, the wallet was waiting out its 10-block change lock (about 20 minutes) — expected.

Which port and difficulty?

3302 for one or two CPUs, 3402 for farms, 3502 for TLS (xmrig --tls or SRBMiner --tls true). To pin the difficulty add d=20000 to the password (minimum 2500 on 3302, 50000 on 3402). HiveOS: pool custom, URL stratum.hashlak.com:3402, wallet %WAL%, worker name in the password.

Disconnected after a few shares?

If half or more of your last 50 shares were invalid the IP is banned for 10 minutes. On RandomX that is usually a memory overclock or missing huge pages. "Unauthorized" in a loop means a wrong address or a subaddress: 3 seconds of ban per retry until you fix it.
