Hash Refinery is in the process of closing down. Outstanding balances above minimum payout levels will be paid for active miners (some activity in the past 90 days).
We are proud to have always made payouts, even following losses due to hacks and exchange closures!
We may reopen in the future if the alt market improves. Thanks for your support these past few years!


By default, yiimp will adjust the difficulty of your miner automatically over time until you have from 5 to 15 submits per minute. It's a good trade off between bandwidth and accuracy.

You can also set a fixed custom difficulty using the password parameter. For example, if you want to set the difficulty to 64, you would use:

-o stratum+tcp:// -u wallet_adress -p d=64

Here are the accepted values for the custom diff:

Scrypt, Scrypt-N and Neoscrypt: from 2 to 65536

X11, X13, X14 and X15: from 0.002 to 0.512

Lyra2: from 0.01 to 2048

If the difficulty is set higher than one of the a mined coins, it will be forced down to fit the lowest coin's difficulty.
