If you’re running a Nym node, keeping your cost parameters updated is key to making sure it’s financially sustainable. This quick guide walks you through the process so you can set everything up smoothly.
Updating Operating Cost on a Nym Node with nym-cli
Properly configuring cost parameters on a Nym node is essential to ensuring its sustainability and profitability. In this guide, we will walk you through the step-by-step process of setting up these parameters using the nym-cli tool.
Step 1: Download nym-cli
To begin, download the nym-cli tool from the official Nym repository by running the following command:
wget https://github.com/nymtech/nym/releases/download/nym-binaries-v2025.5-chokito/nym-cli
Step 2: Update Cost Parameters
To set the operating costs and profit margin for your node, run the following command, replacing "word word word ..." with your mnemonic phrase:
./nym-cli mixnet operators nymnode settings update-cost-parameters \
--mnemonic "word word word ..." \
--interval-operating-cost 800000000 \
--profit-margin-percent 20
Then, grant execution permissions to the downloaded file
chmod +x nym-cli
Explanation of Parameters:
--mnemonic: Your account’s mnemonic phrase, used for authentication.--interval-operating-cost: Defines the operating cost per interval (in this case, 800 Nym).--profit-margin-percent: Sets the profit margin percentage (in this example, 20%).
If you prefer to execute the command in a single line, you can use the following syntax:
./nym-cli mixnet operators nymnode settings update-cost-parameters --mnemonic "" --profit-margin-percent 20 --interval-operating-cost 800000000
