Ravencoin (RVN) mining pool
testnetKawPow · GPU · Block time 60s · Confirmations 102 · PPLNS
Ravencoin is the classic GPU coin: KawPow runs on any NVIDIA or AMD card with 4 GB of memory or more. Point T-Rex or SRBMiner at our Stratum and get paid in RVN to your own wallet — no account, no conversion, every payout on the explorer.
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:3301 | single GPU | 0.02 | — |
| stratum.hashlak.com:3401 | farms / rented hashrate | 1 | — |
| stratum.hashlak.com:3501 | single GPU, TLS | 0.02 | ✓ |

Miner commands
Replace {wallet} with your address and {worker} with a name for the rig, then run.
t-rex -a kawpow -o stratum+tcp://stratum.hashlak.com:3301 -u {wallet}.{worker} -p xSRBMiner-MULTI --algorithm kawpow --pool stratum.hashlak.com:3301 --wallet {wallet} --worker {worker}t-rex -a kawpow -o stratum+ssl://stratum.hashlak.com:3501 -u {wallet}.{worker} -p xAntivirus 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.

/watch rvn1 <WALLET>Common questions about mining Ravencoin
Which cards can mine Ravencoin?
Any GPU with at least 4 GB of memory. NVIDIA cards use T-Rex or SRBMiner, AMD cards SRBMiner. As a rough idea (our own measurements, approximate): a laptop GPU does about 5 MH/s, a desktop RTX 2070 Super about 25 MH/s. Earnings depend on the network hashrate and the price, which change every day.
Which address format does the pool accept?
A mainnet Ravencoin address starts with R; test-network addresses start with m or n. The pool refuses addresses from the other network, and the badge at the top of this page tells you which network the pool is on right now. Mine to a wallet you control.
When and how am I paid?
Every 10 minutes the pool pays every balance above 20 RVN. For Ravencoin the network fee (about 0.08 RVN) is deducted from your payout. A block needs 102 confirmations before its reward becomes spendable balance.
Which port should I use?
3301 for one or two cards, 3401 for farms (higher start difficulty), 3501 for TLS. Vardiff adjusts the difficulty by itself; to pin it add d=0.05 to the password (minimum 0.01 on 3301, 0.5 on 3401). HiveOS flight sheet: pool custom, URL stratum.hashlak.com:3401, wallet %WAL%.%WORKER_NAME%.
The miner says "Authorization failed" or finds no shares
An address from the wrong network is refused and each retry bans your IP for 3 seconds — fix the address and restart. If a browser tab opened the Stratum port, wait 60 seconds. On a laptop T-Rex may need -i 16 --dag-build-mode 1.
